The return on investment of construction organizations is at risk because construction managers fail to execute projects efficiently. The purpose of this single case study was to explore strategies that construction managers used to deliver projects efficiently. The selected population was 10 construction managers from a single construction organization operating in Panama. The conceptual framework for this study was the McKinsey 7S. Data were collected using semistructured interviews, observations, and a review of public documents. Collected data were compiled, disassembled, reassembled, interpreted, and then conclusions were reached, as noted in Yin's 5-step analysis. Themes that emerged from the study included project experience, communication, collaboration, and resource management. Construction managers noted that the review of needed project experience in alignment with the complexity of the project is a strategy to deliver projects efficiently. Leaders of construction organizations can increase strategic performance by implementing collaboration and leadership programs in accordance with the business objectives. By improving labor productivity, construction companies can complete construction projects faster and with lower construction costs. The findings of this study could contribute to positive social change by providing communication and collaboration strategies between construction organizations and local communities to source local staff and resources. Construction managers might benefit from the findings of this study by increasing their project management skills, an effect that could result in long-term employability.

Byggbranschen står idag inför stora utmaningar gällande rekrytering av erfarna projektledare. Företagen har upplevt svårigheter med att hitta erfarna projektledare, detta beror på att det saknas nästan två generationer av projektledare samt att många går i pension. En lösning till problemet är att anställa nyexaminerade projektledare för att fylla luckan. Problemet med nyutexaminerade är att de saknar erfarenhet när de kommer ut i arbetslivet. Det är en utmaning för konsultföretagen, eftersom inlärningstiden för att bli projektledare vanligtvis är långa perioder. Syftet med denna studie är att förtydliga inlärningstiden för de nyutexaminerade projektledare samt att ge organisationen ett underlag för att de ska kunna se vad de bör skapa för förutsättningar och metoder. Huvudfrågorna som behandlas i vår studie är ”Vad innebär det att vara projektledare?” och ”Vad krävs för att man skall gå från att vara en nyutexaminerade byggingenjör till att bli projektledare?” Undersökningen är en kvalitativ studie som genomförts på WSP Management Östergötland. Den empiriska datainsamlingen har skett via personliga intervjuer med elva respondenter fördelade på Norrköping och Linköping kontoren. Studien visar på att vara projektledare kan variera mycket beroende på hur man väljer att tolka det, men inom byggbranschen handlar det om att leverera en produkt eller ett resultat till en begränsad budget och till en bestämd tid. Som projektledare är man beställarens ”högra hand” och ska uppfylla kundens önskemål i projektet. För att detta ska gå ihop krävs ständig kommunikation så att man förstår varandra och undviker missförstånd. Med utgångspunkt från undersökningen har vi även konstaterat att det som krävs för att man ska gå från att vara nyexaminerad byggingenjör till att bli projektledare inom området management, är rätt metod, rätt organisatoriska- och individuella förutsättningar samt att man övervinner krav och hinder som ställs från beställarsidan.

Cost overrun is prevalent in the construction industry. Usually, an owner sets a budget at the preliminary phase of a project which changes over time. Past studies are focused on analyzing the cost growth of design-bid-build projects during construction. Limited efforts have been made to analyze details of projects delivered with the Construction Manager General Contractor (CM/GC) method. This study tracks and analyzes the construction cost variation of a project from the conceptual phase to the design completion phase. The analysis is presented with a case study of a new stadium construction project. It identifies that the changes in the scope and design of the project due to the change in available budget were a major reason for variation in the cost estimates over time. Further, this study identifies a) trades with the highest variation in subcontractors’ bids, b) trades that were most overestimated, and c) trades that were most underestimated. The findings of this study is expected to aid owners, designers, and contractors of future projects in improving the preparation, planning, and estimating of future projects; reducing cost variation within trades; and optimizing the amount of contingency required to ensure the successful completion of similar projects.

Optimum construction worker (CW) performance is required to achieve project delivery within project parameters. It is not always the case as CWs are regularly exposed to hazards, involved in accidents, their productivity is poor, they suffer from ill health, suffer from work-related musculoskeletal disorders (WMSDs) and contractors lack resources to allocate towards H&S. However, the lack or the absence of health and safety (H&S) measures, which the aforementioned depend on, has a negative impact on workers’ performance. Two descriptive surveys were conducted among professional construction project managers (CPMs) registered with the South African Council for Project and Construction Management Professions (SACPCMP) and general contractors (GCs) registered with the East Cape Master Builders Association (ECMBA). Interviews were also conducted with CPMs registered with the SACPCMP residing in the Nelson Mandela Bay metropolitan area. The salient findings include: • Accidents, which occur on construction sites, impact workers’ performance; • Inadequate H&S implementation affects both CW skills and motivation, which in turn affects their performance; • Poor constructability is relevant to H&S and CWs’ skills; • Provision and maintenance of welfare facilities are commonly inadequate and affect workers’ performance, and • Projects do not benefit from the adequate financial provision for H&S. It was concluded that exposure to hazards, poor site conditions, inadequate provision of welfare facilities, WMSDs, and insufficient financial provision for H&S affect workers’ performance by either incapacitating or demotivating them. Recommendations include : CPMs should make better use of their influence on clients; they should improve communication channels between project stakeholders; legislators need to raise awareness regarding H&S and worker welfare, and training and education institutions need to empower workers and professionals with H&S knowledge.

With the advent of major advances in current information technology, many business leaders and academicians hail the arrival of a new decentralized economy based on globally networked teams. This dispersed "market-oriented" structure is a new reality for many current industrial organizations who must transform from fully-integrated, centralized organizations into loose networks of suppliers and sellers utilizing just-in-time collaboration to develop and manufacture new products and services world-wide. Recent trends in manufacturing, where companies are now pursuing ventures outside their own organizations, highlight the need for empirical studies on the nature of the collaborative innovative processes within multi-organizational project teams. In construction, temporary organizations of allied firms join together for the express purpose of completing large, complex projects. An analysis of the construction industry provides a unique opportunity to analyze the innovative nature of the multi organizational project team. A combination of organization, economic, and innovation theory is used to identify factors that enhance multi-organizational project team innovation. Various factors, including principal-agent relationships, cooperation mechanisms, learning mechanisms, and network utilization, are examined to determine their influence on multi-organizational project team innovation. Seven contracting companies are investigated in the performance of twenty-nine different construction projects. Project information is obtained from actual project team members. Fifty innovations are identified from the project sample and used for analysis. The innovations are measured by project in terms of their number and impact on the operations of the general contractor or construction manager. The analysis examines the correlation between various factors and the innovation activity found on each construction project. This research is a step towards understanding the nature of the multi-organizational project team and its capacity to innovate. Project leaders can use this information to better organize project teams for innovation while construction companies and other construction industry firms can use this information to evaluate their innovation strategy.

Det har blivit allt viktigare för organisationer och deras projekt att hantera hållbarhet. Tidigare studier har till störst del fokuserat på hållbarhet och projektledning som separata forskningsområden, vilket medför att det krävs mer förståelse relationen mellan områdena. Med hänsyn till byggbranschens omfattande miljöpåverkan studeras byggprojekt som en specifik kontext i den aktuella studien och syftet är att ta reda på hur hållbarhet i byggprojekt hanteras. Studien är av kvalitativ art där 11 projektledare från bygg- och fastighetsbranschen har intervjuats. Resultatet presenteras i fyra teman: (1) Vem bär ansvaret?, (2) Kunskap i centrum, (3) Kostnad, tid och hållbarhet i målkonflikt och, (4) Prioriteringar. Studien visar att projektledare har en upplevelse av att det är många hållbarhetskrav som ska hanteras och att det medför många aspekter att ta hänsyn till. Arbetet med att hantera hållbarhetskraven påverkas av kunskap, ekonomi och tid samt tendensen av att hålla andra parter i och kring projekten ansvariga för att förbättra hållbarheten i byggprojekt. Av studien framkommer det att projektledarens roll, ansvar och kunskap om projektledning är faktorer som genomsyrar hur hållbarhetskrav i byggprojekt hanteras. För att främja och förbättra byggprojektens hållbarhet behöver projektledare ta större ansvar för hållbarhetsarbetet samt fördjupa sina projektledningskunskaper, för att bättre kunna styra arbetet och prioritera mellan olika krav.
The importance for organizations and projects to adopt sustainability has increased. Previous research has so far mainly treated sustainability and project management as separate research areas, resulting in a lack of understanding in the merged field of sustainable project management. Therefore, is sustainable project management a research area of interest and the context of this study is construction projects, considering the significant environmental impact of the construction industry. The aim of this thesis is research how sustainability is manged in construction projects This qualitive study includes interviews with 11 project managers in the construction- and real estate sector. The result consists in four themes: (1) Who´s responsible?, (2) The power of knowledge, (3) Conflict between time, money and sustainability, and (4) Priorities. The study shows that the project managers have numerous sustainable requirements to acknowledge, which lead to managers having many different aspects in consideration during the project. Four factors were identified to impact the sustainable work in construction projects; economics and time, knowledge, and a tendency to hold other stakeholders responsible for the sustainability outcomes. The results establish the importance of project managers’ responsibility of projects’ sustainability, as well as knowledge of project management. Therefore, in order to improve the sustainability of construction projects, project managers need to take more responsibility of the sustainability work and deepen their knowledge of project management to manage the projects better and prioritize between different requirements.

Digitalization is a hot topic in the construction industry today, with more and more ICT-tools being used. Web-based project platforms, digital meetings and BIM have all existed for quite a while, however the progress in using them and exploring the potential takes time. ICT-tools are usually aimed to make the information flow and communication more efficient, which directly relates to the project manager in a construction project. Therefore, the aim of this thesis is to understand how digital tools has affected the role of the client’s construction project manager over the last 5 years. The purpose is to gain knowledge on what consequences the use of digital tools such as BIM, digital project platforms and digital meetings has had on the role of the project manager and how they deal with the consequences. In this thesis, a qualitative study has been performed, where construction project managers were interviewed about their experiences of ICT-tools and the changes that has occurred over time. The findings were analyzed with a theoretical framework and discussed together with previous research and knowledge. The theoretical framework includes key aspects of leadership in project management and four main categories explaining how actors use ICT. The use of BIM was in particular analyzed using the Bew-Richards BIM maturity model. The study shows that there has been an increase in use of ICT-tools in construction projects over the last 5 years, and that there are both benefits and challenges for the project manager with all three types of digital tools that were in this study. BIM, digital project platforms and digital meetings. The primary benefits were shown to be that the tools increase timeefficiency in the project manager role and it facilitates communication. However, there is less personal contact with project team members and other challenges with getting project participants to the same use of the tools. To increase the significance of the benefits and decrease the negative consequences, the construction project manager should implement a leadership style focused on the human side, with more follow-ups, structure and routines. Technical knowledge about the ICT-tools is also beneficial to the project manager to have since it increases the possibility to guide the project team members in a good way.
Digitalisering är ett hett ämne i byggbranschen, med mer och mer ICT-verktyg som används. Webb-baserade projektplattformar, digitala möten och BIM har alla existerat ett tag nu, men utvecklingen av användandet och utforskningen av deras potential tar tid. ICT-verktyg är ofta avsedda för att effektivisera informationsflödet och kommunikationen, vilket relaterar till projektledaren i ett byggprojekt. Därför är ändamålet med det här examensarbetet att förstå hur digitala verktyg har påverkat byggprojektledarollen på beställarens sida, under de senaste 5 åren. Syftet är att få kunskap om vad för konsekvenser användningen av digitala verktyg så som BIM, digitala projektplattformar och digitala möten har medfört för en projektledare och hur de hanterar konsekvenserna. I det här examensarbetet har en kvalitativ studie gjorts där byggprojektledare intervjuades om deras erfarenheter av ICT-verktyg och de förändringar som har skett över tid. Resultaten analyserades med hjälp av ett teoretiskt ramverk och diskuterades tillsammans med tidigare forskning och kunskap. Det teoretiska ramverket inkluderar vissa nyckelaspekter av ledarskap inom projektledning och 4 huvudsakliga kategorier som beskriver hur aktörer använder ICT. Användningen av BIM var särskilt analyserad genom Bew-Richards model för BIM mognadsgrad. Studien visar att det har varit en ökning av användandet av ICT-verktyg i byggprojekt de senaste 5 åren, och att det är både fördelar och utmaningar för projektledaren med de tre typerna av digitala verktyg som var med i denna studie. BIM, digitala projektplattformar och digitala möten. De främsta fördelarna visade sig vara att verktygen ökar tidseffektiviteten i projektledarrollen och underlättar kommunikationen. Det blir dock mindre personlig kontakt med projektdeltagare och andra utmaningar med att få med projektdeltagare på samma användande av verktygen. För att öka betydelsen av fördelarna och minska de negativa konsekvenserna, borde projektledaren implementera en ledarskapsstil som är mer fokuserad på den mänskliga sidan, med mer uppföljningar, struktur och rutiner. Teknisk kunskap om ICT-verktygen är också fördelaktiga för projektledarna att ha eftersom det ökar möjligheten att vägleda medlemmarna i projektet in på rätt väg.

Project teams that deliver high risk, complex projects in the civil construction industry need tools to enable successful delivery. Construction Manager/General Contractor (CM/GC) is an innovative alternate delivery method, providing one such a tool. CM/GC furnishes public agencies with an attractive option for delivering projects in a less adversarial and more constructive manner by involving the contractor during design. The sophisticated public owner does not have to relinquish control of the details of the design in order to accelerate the schedule or see the benefits of real-time cost estimating data. There are also significant cost and schedule benefits with not degradation in quality. However, because CM/GC is relatively unknown to the civil construction industry much remains to be investigated about how CM/GC processes effect successful project delivery. This research investigated how CM/GC processes affect the three critical elements of construction process risks (including quality, schedule, cost and collaboration), project specific risks, and innovation. By identifying the processes that benefit these elements, successes can be repeated and increased. Additionally, an understanding of the differences in the perception of CM/GC processes, given by contractors, owners, and design engineers, provided perspective into improving the process. Analyzing data on current CM/GC projects and programs, as well as the compiled experience of field-experienced project teams, provided the information the industry needs to pursue implementation. Identified advantages of the process can be tied to strategies for successful delivery. Identified disadvantages expose barriers to implementation to be overcome by the project team. Project teams state that while the process does have disadvantages, many are perceptional and not fatal flaws to the method. Findings of this research link CM/GC processes to robust risk management results and the opportunity for successful innovation.

Mestrado em Gestão de Projetos
Propósito: A direção de obra face à gestão de projeto na perspetiva dos diretores de obra, no sector da Construção/Indústria em Portugal. O aparecimento de um novo interveniente, o gestor de projeto, no sector da Construção e Indústria em Portugal tem sido no meio profissional assunto de discussão e análise. O que se questiona profissionalmente é a forma de como será feita a inserção do gestor de projeto com as suas funções, num palco onde historicamente já existem intervenientes que pelo menos parcialmente as exerciam. De entre estes intervenientes destaca-se o diretor de obra cujas funções de coordenação, pelo menos aparentemente, parecem coincidir com as do gestor de projeto. O propósito da presente dissertação é o de abordar esta aparente sobreposição de funções do ponto de vista do diretor de obra. Como objetivos a dissertação pretende aferir as áreas de sobreposição, equacionar as relações de liderança e caracterizar as competências técnicas que os intervenientes devem possuir. Os resultados obtidos, a partir de uma análise qualitativa a inquéritos feitos a um painel de diretores de obra, confirmou a sobreposição das áreas de atuação e o potencial aparecimento de um risco de conflito de lideranças entre os intervenientes em estudo.
Purpose: The project direction versus the project management under the project direction point of view, on the Construction / Industry sector in Portugal. The emergence of a new stakeholder, the project manager, in the Construction and Industry sector in Portugal has been in the professional environment a subject of discussion and analysis. What is questioned professionally is the way in which the insertion of the project manager will be done with his functions, in a stage where historically there has been stakeholders that at least partially exercised them. Among these stakeholders stands out the project director (construction manager) whose coordination functions, at least apparently, seem to coincide with those of the project manager. The purpose of this dissertation is to address this apparent overlapping of functions from the point of view of the project director. As objectives the dissertation intends to assess the areas of overlap, to equate the relations of leadership and to characterize the technical competences that both the stakeholders must possess. The results obtained from a qualitative analysis of surveys carried out on a panel of project directors, confirmed the overlapping of the areas and the potential emergence of a risk of leadership conflict among the studied stakeholders.

The Design/Bid/Build (DBB) delivery method has historically been the most popular and the most effective means of determining the least cost for building a project based upon a set of construction documents. In recent years, however, other project delivery methods, including but limited to Construction Manager/General Contractor (CM/GC) and Design/Build (DB), have slowly taken a share of the construction market away from the DBB delivery method. The choice of delivery method that will produce the best value for an owner in the measurements of efficiency in quality, cost, and timeliness depends upon the type of project and the business culture of the project owner. A unique opportunity for a comparative study was presented by the Meetinghouse Facilities Department (MFD) of the Church of Jesus Christ of Latter-day Saints. The MFD completed over 200 repetitive meetinghouse projects in the U.S. over a five-year period (1999-2003), contracting approximately two-thirds of the projects using a CM/GC delivery method with an attached partnering agreement. The remaining meetinghouses were contracted using a DBB delivery method. A comprehensive comparison was conducted measuring all of the efficiencies created by the selection of delivery method, including short- and long-term costs, direct and indirect costs, construction cycle time, and quality assessment scores. After identifying and then adjusting for several confounding variables in the historical data, the statistical analysis provided evidence that the CM/GC delivery method proved to be the best value for the MFD by producing a total cost savings of over 5.5 percent on the meetinghouse projects when compared to the DBB meetinghouse projects. Construction cycle time was 20% shorter on the CM/GC meetinghouse projects and quality assessment (QA) scores were consistently higher. In regards to a 10-year life cycle repair costs, the CM/GC delivery method produced a higher quality meetinghouse, reducing repair costs by 34% when compared to the DBB meetinghouse projects.

The construction sector is one of the most important industries for the economy in Sweden. Between 2010 to November of 2020, there has been an increase in employment in the construction industry by 35.4 percent. In 2019 the Swedish construction sector was valued at EUR 53.3 billion, where the construction sub-sector makes up 47.6 percent (European Construction Sector Observatory - Country profile Sweden, 2020).  The construction industry is a fundamental part of society, whereas labor productivity, which represents the quantity of work performed per hour (Park 2006), is a vital element in the process of construction. Gunduz et al. (2020) state that labor consumes a significant amount of cost in construction projects, thus labor productivity is a determinator of cost optimization i.e., the process of making something as good or effective as possible (Cambridge Online Dictionary, n.d.). The benefit of productivity is seen as reduced construction time and cost (Fox, Marsh & Cockerham, 2010). Moreover, a lack of effective management activity towards construction resources can potentially decrease labor productivity. Thus, the familiarity of project managers with labor productivity factors is of major importance (Shehata & El-Gohary, 2011) and contributes to project success (Gunduz & Abu-Hijleh, 2020).

The briefing process is critical for achieving project success and client satisfaction. It typically involves the consultant project manager co-ordinating the efforts of the demand and supply side stakeholders at the conceptual stage of a project, to identify and define the client requirements. The importance of such early intervention has been highlighted by public sector agencies and professional bodies, leading to the publication of numerous guidance notes and best practice manuals for briefing. Despite such extensive guidance literatures and efforts research shows that current briefing practice is inadequate and a weakness in the construction process. Broadly, the briefing process involves consultant project managers from different background and personality traits. Personality traits are thought of as a pervasive style of thinking, feeling and behaving. The literature demonstrate effective performance relates to an individual`s personality traits. The study attempts to evaluate the influence of personality traits of the consultant project manager on the briefing process. A review of the literature is structured under three chapters; (1) briefing process; (2) consultant project manager role in briefing and; (3) personality traits relationship and influence on performance to introduce a new perspective. It is found that there are correlations between personality traits and effective performance. From the review sixteen traits have been extracted and assessed to be related to the consultant project manager performance in construction briefing. The investigation attempts to establish the relationships between the 16 traits and the consultant project manager performance, and seeks to determine how each trait contributes to effective briefing. This is explored through observing the consultant project manager in briefing and an industry wide questionnaire survey. As the research focuses on the influence of sixteen personality traits on the consultant project manager performance in the briefing process the data was analysed by the Pearson product moment (correlation) coefficient method to evaluate relationships. The research concludes that the consultant project manager performance is connected to the iii sixteen personality traits dimensions tested and these traits are associated with effective briefing performance. The findings have implications for selecting consultant project managers. The implications of the results of this research, and recommendations for future investigations are discussed.

Byggprojekt är långa, dyra, resurskrävande och involverar ett stort antal människor som tillsammans jobbar mot ett gemensamt mål. Byggprojekt, likt andra typer av projekt som involverar ett större antal människor är beroende av en välfungerande kommunikation, framför allt när mycket pengar och tid står på spel. Byggprojektledare spenderar den större majoriteten av arbetstiden på att kommunicera och agera spindeln i nätet för att säkerställa att rätt information förmedlas till rätt individer och att alla som är involverade vet vad som är deras uppgifter under ett projekt. Syfte var att undersöka projektledarens roll i, och uppfattning av, kommunikationen inom ett byggprojekt. Vi undersökte byggprojektledarnas perspektiv om vad de främsta kommunikationsproblemen är i byggprojekt och vilka lösningar som är tillgängliga. En litteraturstudie inom kommunikationen i allmänhet men även i projekt och byggprojekt genomfördes. 15 byggprojektledare intervjuades i en rad semistrukturerade intervjuer. Valet av denna typ av intervjuer är baserade på den stora mängd data som kan samlas genom det men även öka chansen till att samla in mer spontana och personliga synpunkter. Slutsatserna för att effektivisera kommunikationen i byggprojekt är att öka transparensen i byggprojekt då det anses att det ska var tydligt för de involverade vad ändamålet och planen är vid varje kommunikationstillfälle. Denna ökade transparens minskar risken för missförstånd och den mänskliga faktorns bidragande till skador minskas; vilka är bland annat misstolkning och felaktig informering. För att minimera den mänskliga faktorns negativa påverkan på kommunikationen är det lönsamt på lång sikt för byggföretagen att erbjuda kurser och utbildning inom kommunikation samt att skapa en kommunikationsplan i ett tidigt skede inför varje projekt. De antalet digitala verktyg som används borde begränsas och standardiseras till ett verktyg som de ledande byggföretagen kommer överens om att använda; för att effektivisera kommunikationen.
Construction projects are long, expensive, resource-intensive and involve a large number of people cooperating towards a common goal. Construction projects, like other types of projects that involve a larger number of people, depend on well-functioning communication, especially when a lot of money and time is at stake. Construction project managers spend the greater majority of their working time communicating and acting as the spider in the web to ensure that the right information is conveyed to the right individuals and that everyone involved knows what their tasks are during a project. The purpose was to investigate the project manager's role in, and perception of, communication within a construction project. We examined the construction project managers' perspectives on what the main communication problems are in construction projects and what solutions are available. A literature study on general communication also on communication in projects and construction projects was conducted. 15 construction project managers were interviewed in a series of semi-structured interviews. The choice of this type of interview is based on the large amount of data that can be collected but it also increases the opportunity to attain more spontaneous and personal views. The conclusions for increasing communication efficiency in construction projects are to increase transparency in construction projects as it is considered that it should be clear to those involved what the purpose and plan is at each communication opportunity. This increased transparency reduces the risk of misunderstandings and reduces the contribution of the human factor to harm; which include misinterpretation and misinformation. To minimize the negative impact of the human factor on communication, it is profitable in the long term for construction companies to offer courses and training in communication and to create a communication plan at an early stage before each project. The number of digital tools used should be limited and standardized to a tool that the leading construction companies agree to use; to streamline communication.

Senior construction project managers who fail to create strategies for environmental sustainability risk losing their competitive advantage in the business environment. Based on stakeholder theory, the purpose of this multiple case study was to explore the strategies that senior project managers use to implement environmental sustainability in their construction projects. Data were obtained from semistructured interviews with 4 senior project managers from 4 construction companies located in the midwestern region of the United States who implemented environmentally sustainable practices in their project processes. The data analysis process included methodological triangulation. The interviews were transcribed, interpreted, and coded to generate themes, which were validated through member checking and archival documentation. The centralized themes included (a) stakeholder engagement, (b) terminology, and (c) cost. Construction projects require the use of appropriate strategies for implementation of environmental sustainability in their project processes, lest project failure occurs. The use of stakeholder engagement principles, to strengthen environmental sustainability interests, creates shared concern and helps generate a roadmap for using environmentally sustainable business strategies. The implications for positive social change include the potential to affect business practices by contributing new knowledge to develop strategies that project managers can use for implementing environmentally sustainable practices. Environmentally sustainable construction practices will enhance the social practice of caring for the environment and create health and well-being.

Problemformulering:  Hur påverkas platschefen i sitt arbete i ett byggprojekt utifrån entreprenadformerna total- och generalentreprenad? Hur kan platschefens arbete utformas och avgränsas för att förbättra ledningen av ett byggprojekt utifrån aktuell entreprenadform?   Syfte:                            Syftet med studien är att undersöka hur platschefens arbete påverkas av total- och generalentreprenad och sedan presentera förslag på hur det kan utformas utifrån aktuella entreprenadformer.   Metod:                          Metoden är en kvalitativ analys. Intervjuer är huvudsakliga tillvägagångssättet och sju platschefer och en affärsområdeschef har intervjuats. Litteraturstudier av tidigare examensarbeten och forskningsrapporter samt skrifter och artiklar från branschen har studerats.   Slutsatser:                    Det finns viktigare faktorer för platschefens arbete än själva entreprenadformen i sig. Dessa är bl.a. kvaliteten på handlingarna, projektets storlek, arbetslagets erfarenheter och sammansvetsning, den egna organisationen och tillgängliga stödresurser samt platschefens egna erfarenheter och kunskaper. Entreprenadformen är dock inte utan betydelse. I en totalentreprenad bör platschefen ges möjlighet till att delta i projekteringen för att kunna bidra med sina praktiska byggkunskaper och styra handlingarna mot att bli produktionsvänligare. I en generalentreprenad bör en organisation för hantering av ÄTA-arbeten finnas då det tar mycket tid från platschefen och entreprenören tappar pengar på ÄTA eftersom dem generellt är dåliga på att ta betalt för ÄTA.
Problem:                      How is the job of the site manager effected by the contract forms turnkey and general contract? How can the work of the site manager be designed and defined based on the contract form?   Purpose:                       The purpose of this essay is to study how the site managers’ work is effected by turnkey and general contract and to present suggestions on how the site managers’ work can be designed based on the contract form.   Method:                       The method is qualitative analysis. Interviews are the main approach and seven managers and a business area manager were interviewed. Literature studies of previous theses and research papers as well as publications and articles from the construction industry have been studied.   Conclusion:                  There are more important factors for site managers’ work than the contract form itself. These include the quality of the drawings and documents, the size of the project, the work teams’ experience and how well they function as a team, the organization and the available support resources and the site managers’ own experience and knowledge. The contract form is however not without significance. In a turnkey, the site managers should be given the opportunity to participate in the project design and planning in order to contribute with their practical building skills and guiding documents to be more construction-friendly. In a general contract there should be an organization for the management of CAW because it takes a lot of time from the site manager and entrepreneurs lose money on CAW because contractors generally are bad at charging for CAW.

Enligt undersökningar som har gjorts konstateras att digitala verktyg används mindre inom byggsektorn i jämförelse med andra branscher. Den digitala utvecklingen är viktig för hur byggbranschen kommer att se ut i framtiden. I nuläget finns ett intresse för att öka användningen av digitala verktyg från byggföretaget Skanska. En mobil version av tidplaneringsprogrammet Asta Powerproject finns på marknaden, nämligen Site Progress. Site Progress används för att stämma av projektets aktiviteter via mobila enheter.   Syftet med studien är att undersöka hur en digital avstämning av tidplan går till genom att använda Site Progress. Vidare analyseras applikationens användarvänlighet och målet är att komma fram till om Site Progress skulle kunna implementeras i kommande projekt.   I studien genomförs en undersökning på projekt Kvarteret Trollhättan 31, som är en om- och tillbyggnation av kontor. I början av undersökningen observerades hur avstämningen går till i nuläget på projektet. Därefter genomfördes samma avstämning med det digitala verktyget Site Progress. Undersökningen avslutades med kvalitativa intervjuer i syfte att ta del av produktionsledarnas tankar om det nuvarande arbetssättet samt deras inställning till införande av Site Progress.   Studien resulterar i att Site Progress medför att avstämning sker direkt på plats och att all dokumentation hamnar på en enhet. I nuläget går det ej att tilldela fler personer på en och samma summa i Site Progress Manager, detta kan försvåra arbetet med avstämning. För att Site Progress ska implementeras i arbetet med avstämning av tidplan krävs justeringar för att åtgärda verktygets brister.

The acceleration of globalisation has forced companies to cope with its propulsion in order to become more competitive and internationalised, an internationalisation that creates the importance of knowing how to manage global and virtual teams (GVT). The knowledge in the area today has shown to be vague, generalised and hard to grasp, especially for the unexperienced GVT-project manager. The purpose of this thesis is therefore to study whether the literature regarding how to manage a GVT corresponds with the perceptions in practice and how these findings can contribute to a more efficient project management approach. This study is examined using a qualitative method based upon literature and semi-structured interviews. This foundation is used to provide a deeper understanding of the subject as well as it puts this research questions into the proper context. The interview respondents are from the same organisation, however, from offices located in four different countries. The result shows that there are different perspectives on how GVTs should be managed efficiently, and that different leadership preferences exits. Furthermore, there exists a lot of possibilities, but also challenges that must be coped with in order to reach the team’s full potential. These challenges are connected to the virtual work settings and practical problems as well as the team's heterogeneity and communication structure. It was found that it is important to consider the purpose of the collaboration in order to strategically plan for its initiation and execution.
Globaliseringens acceleration har tvingat företag att hantera sin framdrift för att bli mer konkurrenskraftiga och internationaliserade, en internationalisering som vidare leder till vikten av att veta hur man ska hantera globala och virtuella team (GVT). Kunskapen i området idag har visat sig vara vag, generaliserad och svår att ta till sig, särskilt för den oerfarna GVT-projektledaren. Syftet med detta examensarbete är därför att studera huruvida uppfattningen om hur man ska hantera GVT skiljer sig mellan litteratur och i praktiken samt hur dessa upptäckter kan bidra till ett mer effektivt projektledningssätt. Denna studie undersöks med en kvalitativ metod baserad på litteratur och semi-strukturerade intervjuer. Grunden används sedan för att få en djupare förståelse av ämnet såväl som den sätter rapportens frågeställningar i rätt sammanhang. Intervjurespondenterna är från samma organisation, dock från kontor i fyra olika länder. Resultatet visar att det finns olika perspektiv på hur GVT ska ledas effektivt och att olika ledarskapspreferenser existerar. Dessutom finns det många möjligheter, men också utmaningar som måste hanteras för att nå teamets fulla potential. Dessa utmaningar är kopplade till virtuella arbetssätt och praktiska problem samt teamets heterogenitet och kommunikationsstruktur. Det konstaterades att det är viktigt att överväga syftet med samarbetet för att strategiskt planera för dess initiering och genomförande.

Construction managers aim to deliver successful construction projects; however it is unclear how they perceive construction project success and how they influence that success. Focusing on the construction phase of the project, a Systems Conceptual Framework is induced from the literature review. In-depth interviews undertaken by 10 construction managers, whose experience accounts for over 130 construction projects, provide data to derive categories which populate the Systems Conceptual Framework initially developed. By adopting an unstructured approach to the data collection, a holistic view of how construction managers impact the success of construction projects is acquired. The construction managers' influence on success is identified through the skills, competencies and characteristics which enable success of the construction phase (enablers). This inductive-deductive methodological approach allows the identification of categories and relations between them which, along with the Systems Conceptual Framework, form the Empirical Model. A Pareto analysis was carried out in order to determine the relative relevance categories have against each others. Overall, 56 relations were identified between the 37 categories derived from the data analysis. The results of the research show that the influence of construction managers on project success is determined by twenty enablers. According to the Pareto analysis, 6 enablers were most relevant; they are separated into two interrelated sets: Communication, Leadership and People Management, and Ability to Pull Back, Experience and Technical Skill. This suggests that construction managers consider mastering 'hard' and 'soft' aspects of the job are both equally relevant to the success of the project. The high interconnectivity between the categories is what allows the Empirical Model to be developed; making it the most important finding of this research. Evidence indicates that construction managers work with both a subjective (qualitative) and an objective (quantitative) concept of success. The quantitative concept of success can have between two and four success factors, which are prioritised according to the needs of the client; there is always one critical success factors that leads the project. The subjective concept of success incorporates aspects of the end user and personal satisfaction, and specific characteristics of the project. The results also show that the outcomes of construction projects can be three: success, failure, and a third outcome which is neither, an outcome between success and failure. Participants have identified this last outcome as being the most frequent.

Construction management projects involve complex, dynamic environments resulting in uncertainty and risk, compounded by demanding time constraints. Research indicated project managers have struggled to identify best practices for scheduling construction projects via critical path methodologies while searching for tools to increase timely job completions and budget profits. The purpose of this single case study was to explore the strategies that construction project managers used to manage scheduled construction project delivery on time. The constructivist philosophical worldview was used as the framework for this study. Data were collected from semistructured interviews from 7 project managers from 5 different construction companies selected via purposive sampling throughout Florida. All project managers had at least 15 years of experience and multiple construction projects with managing scheduled project deliveries. Three themes emerged through thematic analysis: project, time delay, and cost. A construction project can have many variables that project managers cannot control such as the issue of on-time scheduling. Project managers identified that a project could be within the budget or cost set for the project and still be on time and go over budget or be within budget and not meet schedule. No broad support was found for agile project management, and no confirmation could be made that principles of philosophical theories were critical for project success. Implications for a positive social change result in creating new jobs during and after construction, bringing new individuals to neighborhoods, schools, and area businesses.

Professionals who experience burnout are less productive and lead to decreases in both profitability and human resource (HR) capital. The purpose of this correlational study was to examine the relationship between construction project duration; project budget; an individual's role on a project; and Maslach's three dimensions of burnout, (a) professional efficacy, (b) emotional exhaustion, and (c) cynicism, for the target population of construction management team members working within the Midwestern United States. Using data from an online survey, a multiple linear regression analysis was used, along with a separate multiple linear regression model, to quantify the relationship of each dimension of the burnout syndrome with the independent variables. Results suggested that there was no statistically significant relationship between the independent variables and burnout, but statistical significance existed with project budget predicting the burnout dimension of cynicism F(2,136) = 6.395, p = 0.013, R2 = 0.05, suggesting that the larger the project budget, the more susceptible the individual to cynicism. Past research has found that increased levels of cynicism in project team members can lead to feelings of alienation and disengagement from the job role. The implications for positive social change include increased awareness of burnout within the construction context and potential modification of existing business practices and operating procedures to avoid employee burnout of project management team members. Business leaders expanding their understanding about predictors of burnout may lead to lower turnover and turnover intentions while increasing productivity and profitability of their organizations.

Innovative technologies for construction project management are constantly emerging in the construction industry's global landscape, yet the rate of failed projects within the Nigerian construction sector due to poor coordination of construction tasks is on the rise. An unanswered question in the literature remains as to why construction project managers in Nigeria remain slow to adopt new technologies for improving decision-making processes and project success rates. The purpose of this qualitative single case study with embedded units was to understand the perceptions of construction project managers in Nigeria regarding their barriers to technology adoption. This study was framed by 2 conceptual models: Usman and Said's model of factors contributing to information and communication technology adoption in Nigerian construction firms and Waziri, Mustapha, and Idris' model of factors influencing IT adoption in Nigerian construction organizations. Semistructured interviews involving 10 participants, reflective field notes, and archival data provided information regarding the barriers to technology adoption experience of construction project managers in Nigeria. Thematic analysis of the textual data and synthesis produced 5 conceptual categories for 14 identifiable themes from the study. The conceptual categories were (a) adoption of technology, (b) culture, (c) organizational performance, (d) innovative technology, and (e) interorganizational collaborations. The findings from this study may serve as a catalyst for positive social change by challenging existing technology-avoidance behavior in the Nigerian construction industry, and opening new opportunities for improved project delivery in the Nigerian national economy.

Thesis (MTech (Business Administration in Project Management))--Cape Peninsula University of Technology, 2019.
Construction projects are deemed to be complex due to the uncertainties in-volved in such projects. The project management literature has outlined chal-lenges that are found in construction projects. It points out that major challenges and problems found in construction projects include cost and schedule overruns. To achieve construction project success a project has to be completed within cost, time and quality standards or performance. To attain success has always been difficult due to the lack of skills and competencies required by construction project managers. A project manager that has the desired competencies to effectively manage cost, time and quality standards in construction projects is needed. Poor management of construction projects is not only in South Africa but it’s a global challenge. Through the combination of qualitative and quantitative research method (also known a mixed method) this study evaluates project manager’s competencies with the objectives of determining the appropriate competencies that could assist a project manager to excellently execute construction projects. This thesis points out that for an effective project manager to successfully manage construction projects requires to have high strength on leadership competency to provide pro-ject leadership, communication competency to direct a way forward in a project and problem solving competency to provide feasible solutions. Provision of project leadership refers to a project manager upholding effective working relationships with colleagues, influencing others to work without being pressurised and provision of vision for the team to know their direction. Direct a way forward in a project refers to a project manager effectively communicating project objectives, speaking to encourage team members to perform tasks effi-ciently and listen actively. Provision of feasible solutions refers to a project man-ager having an ability to identify a problem, seeking best solutions when dealing with problems and exhibiting creativity in problem solving.

One of the main capital expenditures is construction projects; these can provide very large profits. These profits can be used for public projects; that are justified by cost-benefit analysis, or private projects; that are justified by budget constraints. Most projects have a very tight financial plan that is part of a large scheme. As projects are very cost intensive one of the main roles of project managers are to estimate total costs and ensure the budget is kept throughout the duration of the project. Libya is a developing country that has a growing construction industry, however, the management of construction projects frequently experiences challenges with time and cost restraints and this affects the overall performance of the project as well as the performance of the project managers. The main aim of this thesis is to investigate and evaluate the factors that impact project manager performance and their ability to complete and deliver projects successfully in Libya. This study will ascertain the role of project managers, the challenges that project managers in Libya frequently encounter the cause of time and cost overruns within construction projects and the main factors for successful construction projects. This research adopted both quantitative and qualitative research methods. The findings are based upon 300 structured questionnaires distributed to general, project managers working on construction sectors in Libya (Tripoli). Completed questionnaires received were 183. This is a response rate of 61%. The data was analyzed by using factor analysis (FA). A statistical analysis was used to confirm and addressed the issues of reliability and validity of the questionnaire survey as a measuring instrument. In addition structured interviews with qualified project managers were used to confirm that the data collected was truly reflective. Upon the data analysis from the questionnaire survey and structured interview that the project manager is the most important factor affecting the success of the project in construction industries Libya, furthermore project manager skills are important component that influence the performance of project manager. Proposed guideline has been adopted for implementation of balanced scorecard in Libya to help construction organisations improved their strategic management system. Finally, the conclusions, key findings, recommendations to industry, limitations of the study, and possible further work in research were discussed.

A challenge in Lean Construction is how to make it applicable when there is a high degree of complexity and uncertainty. In many construction projects there are changing project requirements, unique products and a need for actions that are highly focused on meeting customer/client expectations. Such scenarios require management methods that are characterised by being flexible and able to react to change. The aim of this thesis is to introduce a method that has such characteristics. Project Management, Lean and Agile paradigms are merged through the application of the fission and fusion approach of nuclear physics. This research is facilitated through a sequential explorative method. In the first instance, interviews with 22 practitioners in the fields of construction project management, Lean and Agile have been conducted. Then a quantitative self-administered questionnaire with 213 useful responses has been utilised to validate the transferability of the interview findings. It is concluded that Lean is not ideally suited to dealing with the dynamic nature of construction projects. Agile methods, which were developed to cope with the high levels of uncertainty inherent to IT projects, are more flexible and able to react to change. Hence utilising Agile-based methods might be the key to the successful utilization of Lean in construction. Therefore a management method based on combining Lean and Agile approaches has potential. Such an approach needs creative thinking to develop a solution that is different to that of “Leagile”. Leagile uses Lean and Agile methods in the execution phase sequentially, through using a decoupling point model to separate the two. This thesis introduces a new paradigm in which such a decoupling or separation does not take place. Rather, project management, Lean and Agile have been merged together to develop a new holistic and strategic framework. The paradigm presented in this thesis is termed “AgiLean Project Management”.

In one of the largest and most important industries in Sweden, the construction industry, the success of the projects can be closely related to how uncertainties of outcomes or risk are managed. For a construction project to be successful, different individuals and organizations need to provide their knowledge and experience to fulfill the project scope. Risk is something that, if properly managed, will make the project achieve and perhaps surpass these goals and if not, make the project underperform. There exist frameworks for how risk should be managed and also theories for how past experience influence future decisions. How risk within construction projects are managed is related to the experience of the team members as well as top management’s insight in the risk management process. Through a qualitative approach, based on literature as well as interviews, this master thesis provides an insight into how the key project participants are managing risk. Further, this study examines possible shortcomings with risk management practices and proposes management strategies for these. In this study, consultants working with both developers and contractors have been included to share their view. The results of this study show that current risk management practices deviate from the practice proposed within research and industry related literature. This makes the construction projects to rely heavily on individual’s knowledge and there is a risk that lessons learned will not be spread within the organization or the society. Further, risk and opportunities are often managed within the same framework which does not provide for risk to be managed accordingly and opportunities to be exploited. It is proposed that professionals within the industry have a risk propensity that is rather unchanged by gaining more experience but there exists a shift in how risk is perceived. These findings are closely related to how much insight top management within the organization have. Today, most efforts are concentrated on how the project is performing in relation to the budget and schedule which makes risk management a reactive rather than a proactive measure.
I en av Sveriges största och viktigaste branscher, byggbranschen, kan byggprojektens resultat vara nära relaterat till hur osäkerheter samt risk hanteras. För att ett byggprojekt ska bli framgångsrikt måste alla inblandande parter bidra med sina kunskaper och erfarenheter för att uppfylla projektets mål. Risk är någonting som genom en bra hantering antingen kan överträffa dessa mål eller istället göra att projektet misslyckas att nå dessa. Det finns ramverk för hur risker ska hanteras samt teorier för hur tidigare erfarenheter påverkar framtida beslut. Hur risker inom byggprojekt hanteras är relaterat till projektgruppernas erfarenhet samt företagsledningens insyn i riskhanteringsprocessen. Genom en kvalitativ studie baserad på såväl litteratur som intervjuer ger denna masteruppsats en inblick i hur de viktigaste projektdeltagarna hanterar risk. Vidare undersöker denna uppsats även vilka risker själva riskhanteringsprocessen har samt föreslår åtgärder för dessa. I denna studie har konsulter med erfarenheter av att arbeta med både beställare och byggentreprenörer inkluderats för att få en så bred syn som möjligt på hanteringen från de olika parterna. Resultatet av denna studie visar att den nuvarande riskhanteringsprocessen inom flera av organisationerna avviker från den modell som förespråkas av forskning och branschorganisationer. Detta gör att organisationerna ofta förlitar sig på individernas kunskap och att lärdomar sprids dåligt inom organisationen och samhället. Vidare så hanteras risker och möjligheter ofta på samma sätt vilket innebär att risker inte hanteras rätt och möjligheter utnyttjas inte. Dessutom verkar yrkesverksamma inom branschen ha en riskbenägenhet som är relativt oförändrad av erfarenhet men deras uppfattning av risk förskjuts. Resultaten är nära relaterade till hur stor insyn och delaktighet organisationernas ledning har i själva riskhanteringsprocessen. Idag handlar det mycket om att ledningen har en reaktiv inställning till risker, efter att dessa fallit ut, istället för att ta till proaktiva åtgärder.

Open Policy has been implemented in China since 1979. A lot of measures have been adopted to improve the performance in different economic domains. Agent Construction Management (ACM) system was introduced in 2004. It is a new project management mode based on agency theory and empowerment theory. It is introduced in the construction industry to improve the performance of government funded projects. This research aims to analyze how to improve project performance by improving the project managers‘ performance through competencies and empowerment based on organizational learning in ACM system. Local project managers‘ competencies are analyzed to find out the disparity between project managers in China and developed countries. The relationships between organizational learning, competencies of Chinese project managers and empowerment are also explored. The competencies of Chinese local project managers are analyzed based on Royal Institution of Chartered Surveyors‘ (RICS) Assessment of Professional Competence (APC). A theoretical framework is developed based on the related literatures and theories. Three hypotheses are established to depict the causal relationships between learning, competency, and empowerment of project managers in ACM system. A field study is carried out to quantitatively test the hypotheses by means of questionnaire elaborated theoretically and situationally. The survey subjects are “A” level project managers in construction consulting organizations in China. 194 valid questionnaires are randomly collected from 75 project management firms in China. SPSS and Structural Equation Modeling techniques (SEM) using AMOS are adopted to analyze the collected data. Most of the hypotheses are supported by the empirical data collected in this research. The empirical data supports that competency level is positively related to learning orientation. The results show that a project manager‘s learning orientation has a significant influence on his/her competency level. While, empirical data shows that there is no direct and significant relationship between competency and job performance of project managers, while empowerment has significant effects on job performance. Based on the understanding of the effects of learning, competency and empowerment on project managers‘ job performance, measures can be adopted to improve the competency and empowerment of project managers, hence leading to better job performance and project performance. Though job performance is not directly related to competency, competency is still a necessary of job performance and can not be neglected. Project management firms should create a learning culture in the firm, and improve the learning orientation of the employees, which will improve employees‘ competency. Empowerment is highly related to job performance which suggests that project managers should be empowered to improve job performance.

With rapid changes in the business environment, more acute competition and increasingly demanding clients, organisations in the construction industry have identified innovation as a means of achieving competitive advantage. Innovation provides an important avenue for firms to improve performance while differentiating their products and services. Research has identified a number of factors as influencing innovation in construction organisations. Primarily these include internal factors such as organisational climate, innovation championing, leadership and exogenous influences such as clients, regulations, technology and the economy. The role of senior management in promoting innovation is widely recognised in literature. However, in the construction and project based environment, very few studies have focused on middle management and how their day to day leadership activities impact on innovation and project performance. The purpose of this study was to improve middle management leadership behaviour in order to facilitate innovation and improve project performance in construction professional services firms. Through a combination of qualitative case study, questionnaire surveys and qualitative interviews, the research identified how the leadership behaviour exhibited by middle managers in the work place could enhance innovation and project performance. The study was undertaken in five phases to reflect the five key objectives for the research. The first phase comprised a review of the literature on innovation to identify key internal and external factors influencing innovation and ultimately, project performance. The second phase involved a case study of three different innovative projects to examine the role of middle managers in facilitating the innovations studied. Phase three of the study investigated the relationships among transformational leadership, innovation championing and organisational climate for innovation while examining how they combine to promote innovation and enhance project performance. Phase four involved qualitative validation of the relationship among the constructs examined in phase three and preparation of leadership development resource for middle managers which was subsequently trialed in phase five. Key findings from the study suggest that transformational leadership behaviour exhibited by middle managers influences innovation by developing an environment conducive to innovation which in turn fosters innovation championing behaviour and ultimately, enhances project performance. The study contributes to knowledge and adds to the understanding of the role of middle managers in facilitating innovation and improving project performance. It demonstrates that the bypass effect of transformational leadership is applicable in the project based environment since transformational leadership of middle managers directly influenced project performance, circumventing project managers. In addition, the cascading effect of transformational leadership was confirmed, as championing behaviour and climate for innovation mediated the relationship between transformational leadership of middle managers and project performance. Furthermore, it revealed that the individual dimensions of transformational leadership influenced innovation and project performance differently. The study found that individualised support was the most influential dimension impacting on innovation championing behaviour, climate for innovation and project performance. Articulating vision and fostering the acceptance of group goals both influenced climate for innovation and project performance. High performance expectation, modelling behaviour and intellectual stimulation influenced innovation championing and project performance. Beyond these the study has highlighted the particular actions which constituted each dimension of transformational leadership and how they influenced the performance of project team members. Through this study transformational leadership development resource has been developed to help middle managers cultivate the expected leadership behaviour that could facilitate innovation and improve project performance. The study also identified how transformational leadership behaviour can be engrained in the day to day working practices of middle managers. The study presents a more positive view of middle managerial role in improving organisational performance contrary to previous negative reporting on this constituency and identifies the need for greater recognition for their role. The study recommends that construction professional services firms should support middle managers to develop transformational leadership behaviour and create the kind of environment where innovation becomes a part of the normal daily work practices. In addition the study opens a new avenue for the study of transformational leadership by using both qualitative and quantitative methods to investigate the impact of the individual dimensions. It recommends that future research adopts the same approach in different contexts to further test the suggested relationships. The study concludes with recommendations for policy makers to give greater attention to incorporating transformational leadership behaviour into the essential set of behavioural competencies managers in the construction industry need to develop beyond their technical skills.

The commitment and retention of employees in the construction industry has been a major concern for a considerable period of time. This problem is exacerbated by the inability of the industry to attract, develop, motivate, and retain employees. These factors have been identified as relating to the communication of employees' expectations in terms of the job role. The aim of this study is to investigate the impact of line managers' communication practices on commitment and retention through the psychological contracts perspective of subordinate construction and project managers. To achieve this aim, the study draws from two well established theories: the concept of the psychological contract which is based on the theory of reciprocity, and Luhmann's social system theory which views communication as the elementary process constituting the social domain. These theories form the basis of exploring the conditions under which perceived employment obligations of line managers, by subordinate construction managers and project managers, have potential impact on their commitment and retention. A selection of construction and project managers in Nigeria and the UK, through an extensive two-stage Delphi study, provided a list of the most significant items of information subordinates in their positions required from line managers in order to undertake their job. The alignment of the expected information versus provided information was contrasted using a Wilcoxon Singed Rank Test which revealed a deficiency in the level of actual provided information by line managers. A further analysis of the perception of the "Communication Style" and the "Nature of communication" and the impact of these communication practices on subordinates commitment and retention show that line managers' communication practices significantly impact commitment and retention of subordinates' in the construction organisations. The findings revealed that organisational commitment and high commitment cannot be achieved without line managers aligning their communication practices with subordinates' expectations to do the job. Specific models are developed to provide a summative overview of line managers' communication practices which impact commitment and retention of their subordinates.

Construction productivity is an interesting phenomenon which was an initial study into time and motion. However this remains a vital part of the construction industry today as it takes into consideration cost-savings, a precise timeous delivery of projects and the correct usage of materials. This phenomenon itself is a huge challenge to many companies in South Africa. The construction industry in South Africa is seen as a tool to alleviate the increasing unemployment and poverty levels. The ruling party, the African National Congress (ANC), has made statements to decrease the unemployment rate and due to these promises, the imposition of the use of local unskilled labour from the local communities has become the norm on the majority of construction projects. This formed the basis of the Expanded Public Works Programme. This initiative has indeed shown a huge success but the programme lacks long-term support. The majority of these workers are taken on short-term projects and thereafter the workers are returned to the unemployment pool. The workers are also aware of the short-term projects and therefore there is a lack of motivation which inevitably affects the productivity on any construction site. This study looks at the challenges faced by contractor's in the Eastern Cape and analyses the effects of the use of unskilled labour from the local community. Questionnaires were completed as a measurement instrument to determine the motivation, leadership style and the communication levels among the unskilled, core and the managers on construction projects. The productivity achievements of the unskilled labour and the core labour will be measured and compared and the findings are discussed.

Aim - The purpose of this thesis is to examine the possibilities for feedback and learning in the construction sector. In addition, it is also examining the possibilities of how to get employees involved into new solutions in a more flexible way.  Theory - Innovation as a science field within construction bases much of its theories on Rogers, Schillings, Slaughters and Tatum’s work on innovation models and how they affect the implementation of the innovation. The theories also regard innovation diffusion and its focus on different actors and how they adapt to an innovation over time and about different key individuals such as Champions and Gatekeepers and their role in spreading the innovation.  Method - This thesis is a qualitative study with an inductive approach which was conducted as a case study on a consultant company in Uppsala, Sweden which is active in the construction industry. 10 interviews were conducted with different project managers and two more interviews with individuals with connection to their work. In addition, an observation study was also carried out. Findings - The results showed that the innovation process is not prioritized due to time requirements and that it is not the main task of the consultant to be innovative. They should rather focus on delivering a stable product for its customers. However, the co-workers do overall want to be more innovative but the current way of spreading and delivering new solutions might not be the best suitable way based on the time it requires for them to engage in the innovation.  Conclusion - The conclusion is that key individuals could be implemented and reduce other colleagues’ workload in the innovation work by absorbing ideas and new innovations. And summarize and visualize its benefits to the entire team.

ABSTRACT KeyWords: Project Manager, Project Management Knowledge, Construction Project Management, Personality Trait, Questionnaire Survey No objective evaluation method exists for evaluating what kind of knowledge is needed for a construction project manager in accomplishing his works in Taiwan. Therefore, the evaluation and education for project managers depend on the accumulation of their experience. Based on previous methodologies, this study classified the knowledge into the implicit knowledge that is represented by the big five personality trait model, and the explicit knowledge that is collected from the body of knowledge proposed by some international professional institutes. The evaluation items for the implicit and explicit knowledge were collected from the literature and then discussed with domain experts. The feasibility for those evaluation items were collected by questionnaire survey and analyzed by statistical methods. This study found that the person has the personality trait of conscientiousness is suitable for being a construction project manager; a construction project manager urgently requires the personality trait of achievement striving. Furthermore, for the explicit knowledge, construction project managers require the project management knowledge, that includes (1) schedule management, (2) cost management, (3) procurement management, (4) safety management, (5) scope management and (6) quality management. For the implicit knowledge, construction project managers require the construction domain knowledge, including (1) synthesis and evaluation and (2) principles and context of construction domain knowledge. Based on the findings by factor analysis and other statistical methods, this study developed an evaluation metric for construction project manager, that metric consists of eight dimensions, i.e., (1) emotion management, (2) work execution, (3) basic concept, (4) planning and risk management, (5) control and management, (6) financial management, (7) contract management and (8) specified construction skills. The study results can be as the basis for developing training materials and as the index for employing professional construction managers.

abstract: The goal of this research study was to identify the competencies the Project Manager (PM) will need to respond to the challenges the construction industry faces in 2022 and beyond. The study revealed twenty-one emerging challenges for construction PMs grouped into four primary disruptive forces: workforce demographics, globalization, rapidly evolving technology, and changing organizational structures. The future PM will respond to these emerging challenges using a combination of fourteen competencies. The competencies are grouped into four categories: technical (multi-disciplined, practical understanding of technology), management (keen business insight, understanding of project management, knowledge network building, continuous risk monitoring), cognitive (complex decisions making, emotional maturity, effective communication), and leadership (leveraging diverse thinking, building relationships, engaging others, mentoring, building trust). Popular data collection methods used in project management research, such as surveys and interviews, have received criticism about the differences between stated responses to questions, what respondents say they will do, and revealed preferences, what they actually practice in the workplace. Rather than relying on surveys, this research study utilized information generated from games and exercises bundled into one-day training seminars conducted by Construction Industry Institute (CII) companies for current and upcoming generations of PMs. Educational games and exercises provide participants with the opportunity to apply classroom learning and workplace experience to resolve issues presented in real-world scenarios, providing responses that are more closely aligned with the actual decisions and activities occurring on projects. The future competencies were identified by combining results of the literature review with information from the games and exercises through an iterative cycle of data mining, analysis, and consolidation review sessions with CII members. This competency forecast will be used as a basis for company recruiting and to create tools for professional development programs and project management education at the university level. In addition to the competency forecast, the research identified simulation games and exercises as components of a project management development program in a classroom setting. An instrument that links the emerging challenges with the fourteen competencies and learning tools that facilitate the mastering of these competencies has also been developed.

abstract: Much of the water and wastewater lines in the United States are nearing the end of their useful life. A significant reinvestment is needed in the upcoming decades to replace or rehabilitate the water and wastewater infrastructure. Currently, the traditional method for delivering water and wastewater pipeline engineering and construction projects is design-bid-build (DBB). The traditional DBB delivery system is a sequential low-integration process and can lead to inefficiencies and adverse relationships between stakeholders. Alternative project delivery methods (APDM) such as Construction Manager at Risk (CMAR) have been introduced to increase stakeholder integration and ultimately enhance project performance. CMAR project performance impacts have been studied in the horizontal and vertical construction industries. However, the performance of CMAR projects in the pipeline engineering and construction industry has not been quantitatively studied. The dissertation fills this gap in knowledge by performing the first quantitative analysis of CMAR performance on pipeline engineering and construction projects. This study’s two research objectives are: (1) Develop a CMAR baseline of commonly measured project performance metrics (2) Statistically compare the cost and schedule performance of CMAR to that of the traditional DBB delivery method A thorough literature review led to the development of a data collection survey used in conjunction with structured interviews to gather qualitative and quantitative performance data from 66 completed water and wastewater pipeline projects. Performance data analysis was conducted to provide performance benchmarks for CMAR projects and to compare the performance of CMAR and DBB. This study provides the first CMAR performance benchmark for pipeline engineering and construction projects. The results span across seven metrics in four performance areas (cost, schedule, project change, and communication). Pipeline projects delivered using CMAR have a median cost and schedule growth of -5% and 5.10%, respectively. These results are significantly improved from DBB baseline performance shown in other industries. To verify this, a statistical analysis was done to compare the cost and schedule performance of CMAR to similar DBB pipeline projects. The results show that CMAR pipeline projects are being delivered with 6.5% less cost growth and with 12.5% less schedule growth than similar DBB projects, providing owners with increased certainty when delivering their pipeline projects.

abstract: The demand for new highway infrastructure, the need to repair aging infrastructure, and the drive to optimize public expenditures on infrastructure have led transportation agencies toward alternative contracting methods (ACMs) such as design-build (DB) and construction manager/general contractor (CM/GC). U.S. transportation agencies have substantial experience with traditional design-bid-build delivery. To promote ACMs, the Federal Highway Administration and the National Cooperative Highway Research Program (NCRHP) have published ACM guidance documents. However, the published material and research tend to focus on pre-award activities. The need for guidance on ACM post-award activities is confirmed in NCHRP’s request for a guidebook focusing on ACM contract administration (NCHRP 2016). This dissertation fills the crucial knowledge gap in contract administration functions and tools for DB and CM/GC highway project delivery. First, this research identifies and models contract administration functions in DBB, CM/GC, and DB using integrated definition modeling (IDEF0). Second, this research identifies and analyzes DB and CM/GC tools for contract administration by conducting 30 ACM project case studies involving over 90 ACM practitioners. Recommendations on appropriate use regarding project phase, complexity, and size were gathered from 16 ACM practitioners. Third, the alternative technical concepts tool was studied. Data from 30 DB projects was analyzed to explore the timing of DB procurement and DB initial award performance in relation to the project influence curve. Types of innovations derived from ATCs are discussed. Considerable industry input at multiple stages grounds this research in professional practice. Results indicate that the involvement of the contractor during the design phase for both DB and CM/GC delivery creates unique contract administration functions that need unique tools. Thirty-six DB and CM/GC tools for contract administration are identified with recommendations for effective implementation. While strong initial award performance is achievable in DB projects, initial award performance in this sample of projects is only loosely tied to the level of percent base design at procurement. Cost savings typically come from multiple ATCs, and innovations tend to be incremental rather than systemic, disruptive, or radical. Opportunity for innovation on DB highway projects is influenced by project characteristics and engaging the DB entity after pre-project planning.

One of the causes of projects failing to meet their budget and schedule expectations is poor contractor performance. Small-medium sized contractors in the South African construction industry are faced with challenges such as poor management of cash flows, poor access to credit, not having enough capital to drive the project from their own coffers, challenges in obtaining finance, poor planning, challenges with getting competent staff, poor administrative capabilities, lack of experience and poor education, lack of management skills in general and the influence of the client such as imposing unrealistic deadlines. The competencies of the construction project manager are imperative to achieving project success in terms of meeting budget and time expectations. The specific competency of the construction project manager for handling small-medium sized contractors in South Africa are critical analysis, judgement, resource management, engaging communication and motivation. This study explores the need for a collaborative planning framework between small medium sized contractors and the construction project manager in South Africa, to address poor technical and managerial skills of small-medium sized contractors

It has been shown that there exists a correlation between the cost of construction of elementary schools and the project delivery systems. Previous research showed that Competitive Sealed proposal contract method of construction is $4000 cheaper than the Construction Manager at Risk method of construction per student for elementary school construction in Texas. This research investigates the elements causing construction cost variation in elementary schools of Texas by comparing and contrasting the two forms of contract documents, CSP and CMR. Two schools were selected for the study, although the schools are technically in different regions of Texas, the geological record suggests that there is not much difference in the techniques used for foundation construction and hence a reasonable comparison is possible. A comparison was completed of the contract documents for two elementary schools. School A was built using CSP and School B using CMR. The two schools were built for about $13000 per student in line with A. N. Reinisch’s findings for CSP contracts in Texas, but not CMR average costs. The two ISD’s who supplied the documents were clearly concerned at cost control and appear to have managed this process. The earlier findings of a cost difference between CSP and CMR are not overturned by this study. Future studies involving a greater number of schools and the development of a central database are recommended.

Project Management is the most commonly used method for the industry to compete in the ever-changing market. The competency of the project manager is the key factor to the success of the project. This study aims to explore the essence of project manager core competency in construction industry, and has developed a total of 13 core competency measurement indicators upon referring to relevant project management literature. These 13 indicators are found to fall under four major perspectives, including “professional knowledge and experience”, “management skill”, “interpersonal relationship “, and “system integration skill”. This study uses analytic hierarchy process to analyze and has found the importance ranking and relative weights for all measurement indicators. The empirical results show that the order of the most important core competencies of project manager are: “interpersonal relationship”, “professional knowledge and experience”, “management skill”, and “system integration skill”. Among the 13 measurement indicators, the top five indicators which project managers valued most are “communication skill”, “practical experience”, “leadership”, “coordination”, and “integration skill”. Therefore, the finding of the study has shown that the most important ability of the project manager in construction industry is “interpersonal relationship “.

In recent decades, the use of construction manager-at-risk (CMAR) has surged as an innovative construction project delivery method in comparison to traditional competitive bid procurement methods. The conceptual pros and cons of the method are widely accepted throughout the construction industry; however, very little quantitative research exists validating such beliefs. The study presented in this technical paper empirically compares the performance of CMAR to that of the more traditional method of competitive sealed proposal (CSP) in the construction of higher educational facilities. In a study of 33 projects constructed by The Texas A&M University System, 19 procured using CMAR and 14 procured using CSP, observed results show a reduction in schedule growth and change order quantity when using CMAR over CSP. However, additional results show that CSP is more apt to result in decreased project and construction costs than CMAR. Business practices of The Texas A&M University System, statistical significance testing of research data, and practical applications of research findings are included.

abstract: Alternative Project Delivery Methods (APDMs), namely Design Build (DB) and Construction Manager at Risk (CMAR), grew out of the need to find a more efficient project delivery approach than the traditional Design Bid Build (DBB) form of delivery. After decades of extensive APDM use, there have been many studies focused on the use of APDMs and project outcomes. Few of these studies have reached a level of statistical significance to make conclusive observations about APDMs. This research effort completes a comprehensive study for use in the horizontal transportation construction market, providing a better basis for decisions on project delivery method selection, improving understanding of best practices for APDM use, and reporting outcomes from the largest collection of APDM project data to date. The study is the result of an online survey of project owners and design teams from 17 states representing 83 projects nationally. Project data collected represents almost six billion US dollars. The study performs an analysis of the transportation APDM market and answers questions dealing with national APDM usage, motivators for APDM selection, the relation of APDM to pre-construction services, and the use of industry best practices. Top motivators for delivery method selection: the project schedule or the urgency of the project, the ability to predict and control cost, and finding the best method to allocate risk, as well as other factors were identified and analyzed. Analysis of project data was used to compare to commonly held assumptions about the project delivery methods, confirming some assumptions and refuting others. Project data showed that APDM projects had the lowest overall cost growth. DB projects had higher schedule growth. CMAR projects had low design schedule growth but high construction schedule growth. DBB showed very little schedule growth and the highest cost growth of the delivery methods studied. Best practices in project delivery were studied: team alignment, front end planning, and risk assessment were identified as practices most critical to project success. The study contributes and improves on existing research on APDM project selection and outcomes and fills many of the gaps in research identified by previous research efforts and industry leaders.

Abstract in English with Afrikaans and SeTswana translation
Evidence from relevant literature indicates that abandoned and failed projects have become prevalent in the Botswana context. Poor stakeholder management has been identified as a salient contributor to this challenge. To this end, various stakeholder management (SM) frameworks, models and methodologies have been developed. Nevertheless, the increasing incidence of project failure and abandonment in the Botswana construction industry indicates significant underperformance of these SM methodologies. A cursory appraisal of SM models highlights the linearity of the stakeholder relationship management (SRM) curve, i.e. between the client, consultants and contractors, with SRM responsibilities being domiciled with the client or their representative in most cases. Also, the dynamics associated with changes in stakeholder attributes during project delivery are not catered for by extant SM and relationship management models. In addition, extant SM models focus on the relationship between the project stakeholders on the one hand and the external stakeholders on the other, and others cater for project stakeholders alone. This implies that the models currently deployed for SM in the Botswana construction context remain defective. Contracting organisations (contractors) have been blamed for their inability to manage relationships with projects and external stakeholders during project delivery. Yet, these entities are not at the epicentre of SRM on construction projects. This study provides answers to the gaps highlighted. As its central objective, this study set out to develop and validate a contractor-driven stakeholder relationship management framework (CSRMF) for the Botswana construction industry. The emergent framework which leverages on the attributes of the customer relationship model (CRM) overcomes the shortcomings mentioned previously. An interpretivist philosophical paradigm was adopted in this qualitative case study research study based on pre-determined case selection criteria. Owing to the need to attain analytic generalisation through adherence to replication logic, a multi-case study research design was utilised. Six contractor organisations categorised according to scale and operating within Gaborone were selected. The unit of analysis centred on the relationship between the contracting organisations and other project stakeholders on selected projects being procured and delivered under a diverse range of contracting strategies. Data was collected through a sequential multi-method approach in which semi-structured interviews were conducted with project managers representing these construction contracting organisations on the selected projects. To enable replication, care was taken to select two contracting organisations per level – large, medium and small according to prevalent grades. Samples across the different sizes of the contractors allowed for better generalisability. Relevant projects and organisational documents were reviewed. Furthermore, data from the various stages was analysed using the qualitative content analysis technique. The findings of the study show that most of the contractors in Botswana related to their project stakeholders without a model or framework when handling relationship management with project stakeholders. These findings are a reflection of the small, medium and large construction contractors in the Botswana construction industry. There was further indication that the small, medium and large contractors had a way of managing stakeholder relationships and resolving conflicts, and thus the level of experience and knowledge within the contracting firm had a significant influence on how they managed their project stakeholder relationships in the course of project procurement and delivery. In addition, the study findings demonstrate that the nature of contracting strategy had a significant influence on how various categories of contractors related to their stakeholders on construction projects. The traditional method was found to be the main procurement strategy used in the Botswana construction industry, and this approach was fairly rigid to implement effective contractor-driven stakeholder relationship management. Other procurement strategies, such as design-and-build, and construction management are used in Botswana with their positive and negative impacts on contractors’ capability to manage their project stakeholder relationships and related matters effectively. Further evaluation of the findings led to the identification of key success factors for CSRMF development to foster effective contractor-stakeholder relationship management. These key success factors are effective communication, collaboration, engagement and cooperation among clients and contractors and consultants’ commitment; employee (stakeholder) engagement and satisfaction and capacity building; in-depth understanding of all project stakeholders and their importance and influence; and strategies to manage their relationship effectively in the course of project design, procurement and delivery. Based on the evaluation of formulated propositions and analysis of empirical data and results tested in this study, the findings also support the following analytical generalisations: the construction contracting organisations in Botswana do not have any SRM frameworks in place for engaging with stakeholders in their different projects; contractors in Botswana recognise the need to do better in managing their project stakeholder relationships; and there is an apparent gap in technical skills and limited ability of contractors to manage relationships with project stakeholders. Premised on the findings, a contractor-driven stakeholder relationship management framework was developed. The CSRMF was validated by two focus groups, namely sampled project managers from the semi-structured interviews, and relevant professionals and other academics in the industry. The validation was done to assess the relevance of the CSRMF in their management of relations. The CSRMF will provide guidance for bridging the gaps identified. It will be adopted and utilised by contractors to achieve efficiencies in the management of relationships with stakeholders, thus saving time and costs and securing improved quality and, most of all, client satisfaction.
Volgens die literatuur misluk die meeste projekte in Botswana. Swak bestuur deur die belanghebbendes in die projekte is die hoofrede hiervoor. Talle raamwerke, modelle en metodologieë gemik op doeltreffende bestuur van belanghebbendes (BB) is as oplossing vir hierdie probleem voorgestel. Dat al hierdie BB-metodologieë egter gebrekkig is, blyk uit ʼn toename in die aantal mislukte projekte in die konstruksiebedryf wat laat vaar is. ʼn Oppervlakkige ondersoek van die BB-modelle het aan die lig gebring dat die belanghebbendeverhoudingsbestuur- (BVB) kromme afgeplat is. Hierdie kromme gee ʼn aanduiding van die verhouding tussen die kliënt, konsultante en kontrakteurs. Belanghebbendeverhoudingsbestuur berus meestal by kliënte of hulle verteenwoordigers. Die bestaande BB- en verhoudingsbestuurmodelle maak geensins vir veranderinge in die eienskappe van belanghebbendes tydens die lewering van ʼn projek voorsiening nie. Hierbenewens fokus sommige BB-modelle op die verhouding tussen eksterne belanghebbendes en projekbelanghebbendes, en party slegs op projekbelanghebbendes. Om hierdie rede is die modelle wat tans in Botswana se konstruksiebedryf toegepas word, ontoereikend. Kontrakteurorganisasies word dikwels daarvan beskuldig dat hulle nie tydens die lewering van ʼn projek in staat is om hulle verhouding tussen eksterne en projekbelanghebbendes te bestuur nie. Hierdie groepe staan egter nie in die brandpunt van konstruksieprojekte se BVB nie. Hierdie studie poog om oplossings te bied vir die tekortkomings wat aangetoon is. Die oogmerk is ʼn raamwerk vir kontrakteurgedrewe belanghebbendeverhoudingsbestuur (RKBVB) vir die konstruksiebedryf in Botswana. Hierdie raamwerk steun op die kliënteverhoudingsmodel (KVM) om die gemelde tekortkomings te verbeter. Hierdie kwalitatiewe gevallestudie berus op vooraf vasgestelde kriteria vir die keuse van gevalle. Daarby word ʼn interpretatiewe filosofiese paradigma in hierdie studie gevolg. Aangesien analitiese veralgemening volgens die eise van replikasielogika die doelwit was, behels die navorsingsontwerp veelvuldige gevallestudies. Ses kontrakteurorganisasies in Gaborone wat volgens ʼn skaal gekategoriseer is, is gekies. Die verhouding tussen hierdie kontrakteurorganisasies en die belanghebbendes in projekte wat volgens ʼn verskeidenheid kontrakstrategieë verkry en gelewer is, was die ontledingseenheid. Data is volgens ʼn sekwensiële multimetodebenadering ingewin, en halfgestruktureerde onderhoude is met die projekbestuurders van hierdie ix konstruksiemaatskappye gevoer. Om replisering te vergemaklik, is twee kontrakteurorganisasies volgens hulle vlak – groot, middelslag en klein en graad gekies. Die onderskeid op grond die grootte van die kontrakteurs het tot veralgemening meegehelp. Insae is in die projek- en maatskappydokumente verkry. Die data wat in elke stadium ingewin is, is volgens die kwalitatiewe tegniek ontleed. Op grond van die bevindings het die meeste kontrakteurs sonder enige model of raamwerk hulle verhouding met die projekbelanghebbendes bestuur. Hulle verteenwoordig alle klein, middelslag en groot konstruksiekontrakteurs in Botswana. Die gebrek aan kennis en ervaring in die bestuur van hulle verhouding met belanghebbendes en die beslegting van geskille in die verkryging en lewering van projekte was ooglopend. Daar is voorts bevind dat die aard van die kontraktuele strategie ʼn beduidende invloed gehad het op hoe die onderskeie kategorieë van kontrakteurs verhoudings met die belanghebbendes in konstruksieprojekte aanknoop. Verder is bevind dat die konstruksiebedryf tradisionele verkrygingstrategie meestal volg. Hierdie strategie is taamlik rigied en bevorder nie juis kontrakteurgedrewe belanghebbendeverhoudingsbestuur nie. Ander verkrygingstrategieë, soos die ontwerp-en-boustrategie, en konstruksiebestuur word in Botswana toegepas, en kan kontrakteurs se vermoë om hulle verhouding met die belanghebbendes in projekte en aanverwantesake doeltreffend te bestuur, enersyds bevorder en andersyds belemmer. Verskeie suksesfaktore vir kontakteur-belanghebberverhoudingsbestuur (KBVB) is op grond van die bevindings onderskei, te wete effektiewe kommunikasie, medewerking, betrokkenheid en samewerking tussen kliënte en kontrakteurs asook konsultante se verbintenis; werknemer (belanghebbendes) se betrokkenheid, bevrediging en kapasiteitsbou; ʼn grondige begrip van alle belanghebbendes in ʼn projek en van hulle belang en invloed; en strategieë om verhoudings effektief in die ontwerp, verkryging en lewering van ʼn projek effektief te bestuur. Die bevindings, wat op die beoordeling van die geformuleerde voorstelle en ʼn ontleding van die empiriese data berus, het tot die volgende analitiese veralgemenings gelei: konstruksiemaatskappye in Botswana het geen BVB-raamwerk waarvolgens hulle met belanghebbers in projekte omgaan nie; hulle besef dat hulle hul verhouding met belanghebbendes in projekte beter behoort te bestuur; en kontrakteurs beskik blykbaar nie oor die tegniese vaardighede en vermoëns om hulle verhouding met belanghebbendes in projekte te bestuur nie. x ʼn Raamwerk vir kontrakteurgedrewe belanghebberverhoudingsbestuur (RKBVB) is op grond van die bevindings ontwikkel. Die RKBVB is deur twee fokusgroepe gevalideer, naamlik projekbestuurders enersyds en beroepslui en akademici in die bedryf andersyds, ten einde die relevansie van die RKBVB te toets. Die raamwerk help kontrakteurs om die genoemde probleme op te los. Aangesien dit kontrakteurs sal help om hulle verhouding met belanghebbendes doeltreffend te bestuur, sal dit nie alleen tyd en geld spaar nie, maar ook die gehalte van hulle werk en bowenal kliënttevredenheid verbeter.

The construction industry is an important sector in the development and economic progression of South Africa. Moreover, projects in the South African construction industry involve different individuals and organizations that collaborate to achieve a specific task at a specific time. Hence, leadership is essential in any construction organization to achieve organizational goals and to promote individual professional achievement in the industry. This study evaluates different leadership style practices of construction and project managers in the South African construction industry. The study further investigates leadership development approaches in the industry. The data used in this research were derived from both primary and secondary sources. The secondary data were collected via a detailed review of related literature. The primary data were collected through a structured questionnaire aimed at 150 construction and project managers in the South African construction industry. The study revealed that project and construction managers in the South African construction industry prefer transformational leadership, followed by transactional and democratic leadership. It was also revealed that communication skills, vision, honesty and reliability are some of the important traits of a project leader. This study also suggests ways in which leaders can be developed in the construction industry. Formal leadership training, mentoring and personal development are highlighted as some of the ways in which construction leaders can be developed in the construction industry. It is therefore recommended that construction organizations in South Africa should invest more than they are currently doing in leadership development programs, so that future project and construction managers can be developed to be effective leaders in the industry. The current study contributes to the body of knowledge on the subject of leadership in the construction industry. The value of the study is to facilitate and understand the different leadership style practices in the construction industry and to determine the relationship between leadership styles and project success. This research also provides new information on how to improve leadership in the South African construction industry.

Project management is one of the most effective approaches to ensure the success of project on condition of complex environmental factors for the construction industry. However, many researchers have defined the project success, but there isn’t an accordant definition. It is sure that one of the key factors for the project success is the performance of project manager. This study aims at defining and identifying which factors influence the performance of construction project managers. By the discussion and analysis on these key factors, it assumes the performance of construction project manager in the construction industry can be advanced so as to advance the possibility of project success. 132 valid questionnaires from project managers are collected, and the research result is integrated as follows: (1) It identifies if the 48 influential variables have significant importance by one-sample t-Test. The result indicates that the 5 influential variables (work overtime, company size, age, overseas experience, membership of professional institute) don’t reach the significant importance, and the other 43 influential factors have significant influence on the performance of construction project manager in this study. (2) It ranks the influential variables by the mean of their importance. The first five variables are “conscientiousness”, “motivation”, “integrity”, “engaging communication”, and ”sensitivity”. (3) By correlation analysis, the four variables of project membership, annual turnover of the company, work year of being project manager, and year income of the project manager have positive correlation with the 9 influential factors. Therefore, construction project managers with different backgrounds have different views on the influential perspectives. (4) By one-way ANOVA test, it finds the views of construction project managers in the companies with different characteristics have significant difference on the influential variables of “project team relationship”, “ability of project team”, “project experience of company”, and “foreign language”. This study offers some valuable implications for the management to select effective project managers to improve the success of the projects.
