Due to the low productivity growth in the construction industry, there are discussions about theories and tools that could support an increased productivity in construction projects. One such ‘theory’ or package of tools is lean. Lean has been used successfully for decades in the car manufacturing industry, Toyota for example, and in other industries as the shipbuilding industry. In the construction industry, the use of the word lean is not frequently used and construction projects could might implement lean concepts and tools in a greater extent than today. The purpose of this thesis is to increase the productivity in construction projects by evaluating if and in which types of construction projects different lean concepts and tools could be used and when it is worth to implement different lean concepts and tools. The research questions are about if there are any obstacles to implement lean and which lean concepts and tools that are most suitable for different types of construction projects. The findings, that will answer the research questions, are based on a theoretical view from an extensive literature review including prior case studies about lean in general as well as about lean in construction projects. The findings are also based on interviews, about the construction process and lean in construction projects, with managers at different types of projects, constructed by Skanska. Even though lean is already used in some extent in construction projects, the finding is that lean concepts and tools could be used in a greater extent in construction projects without obstacles. In addition to concepts and tools used in the car manufacturing industry, e.g. just-in-time, other concepts and tools have to be added. For example production control and planning are important to support lean in construction projects. In general, lean concepts and tools could be used in all types of construction projects. Some concepts or tools are more preferable in certain types of projects. Lean could be used only by the main contractor, however, to optimize the process by lean concepts and tool, it is preferable if the whole chain is adopting lean thinking. As a final comment, construction projects are not like car manufacturing facilities with repetitive work and products. But the construction industry has to take impact from it and the future will be more like the car industry, if the quality and the architectural creativity could retained in the projects.

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.

The definition of a project is that an individual or group of individuals carries out a work that results in a unique product or service. What is usually discussed in both the media and in the construction industry is the type of project that you can talk about. In this study, this is called conventional construction projects. There are also projects that you are not allowed to talk about and that must be kept secret for various reasons. These can, for example, be based on protecting national interests. In these projects, integrity is one of the most important parameters to keep track of from a management perspective. This study examines the work methodology in this area of the Swedish construction industry. The study is based on traditional project management theory and begins with a review of concepts such as critical success factors (CSF), the distinction between confidentiality and conventionality, key performance indicators (KPI) and the classic iron triangle. The study's question is whether these concepts appear and are applied differently in confidential construction projects compared to conventional ones. Are there any activities that are of utmost importance that they are carried out for a confidential project to be considered successful? The study was conducted as a qualitative, abductive study where information was obtained through semi-structured interviews. In total, eleven interviews were conducted with individuals who participated in some form of confidential construction project. All respondents have represented construction contractors during their time in confidential construction projects. The conclusion after the completed analysis of the interviews shows that confidential projects do not differ significantly in terms of project structure. On the other hand, this type of project is characterized by a much higher degree of accuracy regarding planning and implementation than a comparable conventional construction project.Definitionen av ett projekt är att en enskild eller grupp av individer genomför ett arbete som resulterar i en, på något sätt, unik produkt eller tjänst. Vad som vanligtvis diskuteras i både media och i byggbranschen är den typ av projekt som du faktiskt får prata om. I denna studie kallas detta för konventionella byggprojekt. Det finns även projekt som du inte får prata om och som måste hållas hemliga av olika anledningar. Dessa kan exempelvis vara grundade i nationella skyddsintressen. I dessa projekt är integritet en av de viktigaste parametrarna att hålla koll på ur ett ledningsperspektiv. Denna studie undersöker arbetsmetodiken inom detta område i byggbranschen. Studien tar avstamp från traditionell projektledningsteori, och inleds med en genomgång av koncept såsom kritiska framgångsfaktorer (CSF), distinktionen mellan konfidentialitet och konventionalitet, nyckeltal (KPI) samt den klassiska järntriangeln. Studiens frågeställning är om dessa begrepp ter sig och tillämpas annorlunda i konfidentiella byggprojekt jämfört med konventionella. Är det några aktiviteter som är av yttersta vikt att de genomförs för att ett konfidentiellt projekt ska anses vara framgångsrikt? Studien har genomförts som en kvalitativ, abduktiv studie där informationsinhämtningen har skett genom semistrukturerade intervjuer. Totalt har ett antal om elva intervjuer genomförts med individer som deltagit inom någon form av konfidentiellt byggprojekt. Samtliga respondenter har representerat byggentreprenörer under deras tid i konfidentiella byggprojekt. Slutsatsen efter den genomförda analysen av intervjuerna visar att konfidentiella projekt inte skiljer sig avsevärt mycket sett till struktur på projektet. Däremot karakteriseras denna typ av projekt av en mycket högre grad av noggrannhet avseende planering och genomförande än ett jämförbart konventionellt byggprojekt.

Lean Construction is regarded as an innovative approach of management for various types of projects in the field of construction. As much as it is currently applied in some countries, its expansion is inevitable, for better overall results are obtained and the projects’ objectives are met more precisely. Despite the fact that Lean Construction offers solutions to many problems occurring under the traditional management approach known as the Project Management (PM), the scope of its application is not as promising. Countries where Lean Construction is minimally applied include the United States of America and the United Kingdom besides other countries in Europe and Latin America. However, it is still not applied to a more exhaustive extent in these countries and is completely missing in many others around the world. This study primarily focuses on the application of Lean Construction to Infrastructure, specifically road projects; investigating Lean Construction solutions to the time wastes. Through conducting a case study research, this work focuses on investigating the impact of applying Last Planner System as a Lean Construction tool on the elimination of Non-Value Added (NVA) activities, that is, wastes in a highway project in Cairo, Egypt. This study includes a State of Art on both Project Management approach and Lean Construction. The study applies a comparative approach between the application of Project Management approach and Lean Construction in road projects. Hence, the researcher conducted different simulations of the studied road project, taking into account the two approaches (Project Management and Lean Construction), then obtaining the simulations results. Two parameters are used as comparison criteria: Percentage Plan Complete (PPC) and Percentage Activity Waste (PAW). The later (PAW) is a new parameter introduced by the researcher to investigate its results before/after applying the Lean Construction tools. Findings of the study support the research hypothesis that the application of Lean Construction approach to road projects enhances productivity through eliminating time-related wastes and decreasing the project duration. This research supports the argument that road projects can benefit greatly from the application of Lean Construction instead of the traditional approach.Lean Construction es considerado como un enfoque innovador para la gestión de diversos tipos de proyectos en el campo de la construcción. Por más que se aplique actualmente en algunos países, su expansión es inevitable, ya que se obtienen mejores resultados generales y los objetivos de los proyectos se cumplen con mayor precisión. A pesar del hecho de que Lean Construction ofrece soluciones a muchos problemas que ocurren bajo el enfoque de administración tradicional conocido como Gestión de Proyectos (Project Management, PM), el alcance de su aplicación no es tan prometedor. Los países en los que se aplica mínimamente el Lean Construction son los Estados Unidos de América y el Reino Unido, además de otros países de Europa y América Latina. Sin embargo, todavía no se aplica de manera más exhaustiva en estos países y está completamente ausente en muchos otros en todo el mundo. Este estudio se centra principalmente en la aplicación de el Lean Construction a Infraestructura, específicamente en proyectos viales; Investigando soluciones de Lean Construction para los desperdicios del tiempo. A través de la realización de una investigación de estudio de caso, este trabajo se enfoca en investigar el impacto de la aplicación del Sistema Last Planner como una herramienta Lean Construction en la eliminación de actividades sin valor agregado (NVA), es decir, desechos en un proyecto vial en El Cairo, Egipto. Este estudio incluye un estado del arte tanto en el enfoque de gestión tradicional de proyectos Project Management como en Lean Construction. El estudio se aplica a un enfoque comparativo entre la aplicación del enfoque de el Project Management y el Lean Construction en proyectos viales. Por lo tanto, el investigador realizó diferentes simulaciones del proyecto de carretera estudiado, teniendo en cuenta los dos enfoques (Project Management y Lean Construction), y luego obtuvo los resultados de las simulaciones. Se utilizan dos parámetros como criterios de comparación: Plan de porcentaje completado (PPC) y Porcentaje de residuos de actividad (PAW). El último (PAW) es un nuevo parámetro introducido por el investigador para investigar sus resultados antes / después de aplicar las herramientas de el Lean Construction. Los hallazgos del estudio apoyan la hipótesis de la investigación de que la aplicación del enfoque de Lean Construction a los proyectos viales aumenta la productividad al eliminar los desechos relacionados con el tiempo y disminuir la duración del proyecto. Esta investigación apoya el argumento de que los proyectos viales pueden mejorarse en gran medida con la aplicación de el Lean Construction en lugar del enfoque tradicional el Project Management.

Domingo, Nikula. "Reducing construction waste in healthcare projects : a project lifecycle approach". Thesis, Loughborough University, 2011. https://dspace.lboro.ac.uk/2134/9107.
Pełny tekst źródłaStreszczenie:
Construction waste generation is a global issue in the sustainable construction context and several studies have been performed in different parts of the world to develop methods and tools for waste prevention, reduction, reuse and recycling. Most of these studies adopted a linear approach by focussing on a specific project phase, such as design, procurement or construction. However, there is a consensus in the literature that factors causing construction waste span across the project life cycle and recent researchers emphasised the need for a more integrated lifecycle approach to holistically assess and evaluate causes of waste to suggest recommendations to reduce lifecycle construction waste generation. Over recent years, the UK government has been investing billions of pounds in new and refurbished healthcare projects, where the healthcare buildings are often referred to, in literature, as complex buildings. This large investment has created a number of sustainability issues including water consumption, CO2 emissions, energy consumption, and more significantly construction waste generation. However, no significant research has been undertaken to propose a systematic construction waste minimisation mechanism for healthcare construction projects. Therefore, this research aims to develop a lifecycle construction waste minimisation framework for healthcare projects (HC-WMF). In order to identify the research problem and construction waste generation issues peculiar to healthcare projects, nine preliminary interviews were conducted with healthcare clients (N=3), architects (N=3), and contractors (N=3). The findings revealed that healthcare projects generate high rates of waste compared to other building projects throughout the project lifecycle, identified complex features that have an effect on waste generation, and identified particular causes of construction waste in healthcare projects. A further in-depth study based on four case studies was undertaken to understand the impact of waste generation due to the causes of waste, the relationship between complex features in healthcare projects and the causes of waste, and best waste minimisation practices to be implemented throughout a healthcare project lifecycle to address construction waste causes. Three interviews (client, architect, and contractor) from each case study were undertaken during the data collection stage. A Healthcare Construction Waste Minimisation Framework (HC-WMF) and Self-Assessment Tool (SAT) were then developed based on the findings of the literature review, preliminary data collection study and case studies, and adoption of the key concepts of problem solving methodology. This HC-WMF comprised six waste minimisation strategies (project documents management, stakeholders waste awareness, communication and coordination, buildability, materials selection and procurement, and change management) to be followed throughout the lifecycle stages of a healthcare project. SAT provides a means to assess the effectiveness in implementing HC-WMF and to obtain feedback and learning outcomes for continuous further improvements. In order to validate the developed HC-WMF and SAT a validation questionnaire (N=26) and validation interviews (N=4) were conducted. The validation results showed that the HC-WMF and SAT would be very useful in reducing construction waste generation from healthcare projects. The research contributes to construction waste minimisation research introducing a novel approach to lifecycle waste reduction. Also, the research revealed the complex features in healthcare projects that affect construction waste generation, causes and origins of waste peculiar to healthcare projects, and best waste minimisation strategies to implement to reduce construction waste generation from healthcare projects. Most importantly, through HC-WMF, this research produced a set of guidelines to be followed throughout the healthcare project lifecycle to reduce construction waste generation. The study has made recommendations which, if adopted, will lead to significant improvements in sustainable healthcare construction due to construction waste minimisation. The content should be of interest to clients, designers, and contractors dealing with construction waste minimisation and sustainable construction in healthcare projects. Key words: Construction waste, Healthcare, Causes of waste, Healthcare complexities, Waste minimisation, UK.

For decades, Army Engineers have utilized the systems of the Critical Path Method (CPM) and multi-level Gantt chart planning system for its construction projects. While these methods are well accepted, they are not without their flaws. Research and literature in project management has given weight to several viable alternative options to planning projects. One such option, Critical Chain Project Management (CCPM), was developed to address the flaws of CPM by offering a holistic approach to project management based on strict resource control and the use of time buffers. This method attempts to eliminate multitasking and procrastination that can plague efficiency and offer managers more flexibly on tasks that otherwise had no leeway. CCPM may give project managers more flexibility and control while at the same time shortening the overall length of a project, saving time and money.
The purpose of this thesis was to address the time saving and resource management benefits of utilizing CCPM over CPM and analyze the viability of those benefits being applied to U.S. Army Corps of Engineers construction project planning. Through the use of surveys of Army Engineer project supervisors, several key factors that cause delays because of CPM were identified and rated. The validity of CCPM based solutions to the same issues were also assessed by Army project supervisors in the survey. Analysis of the survey results indicated that CCPM may offer solutions to major issues that Army project supervisors face.

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.

Pełny tekst źródłaStreszczenie:
The problem of delays in the construction industry is a global phenomenon and the construction industry in Brunei Darussalam is no exception. The goal of all parties involved in construction projects – owners, contractors, engineers and consultants in either the public or private sector is to successfully complete the project on schedule, within planned budget, with the highest quality and in the safest manner. Construction projects are frequently influenced by either success factors that help project parties reach their goal as planned, or delay factors that stifle or postpone project completion.
The purpose of this research is to identify success and delay factors which can help project parties reach their intended goals with greater efficiency. This research extracted seven of the most important success factors according to the literature and seven of the most important delay factors identified by project parties, and then examined correlations between them to determine which were the most influential in preventing project delays.
This research uses a comprehensive literature review to design and conduct a survey to investigate success and delay factors and then obtain a consensus of expert opinion using the Delphi methodology to rank the most needed critical success factors for Brunei construction projects. A specific survey was distributed to owners, contractors and engineers to examine the most critical delay factors. A general survey was distributed to examine the correlation between the identified delay factors and the seven most important critical success factors selected. A consensus of expert opinion using the Delphi methodology was used to rank the most needed critical success factors for Brunei building construction.
Data was collected and evaluated by statistical methods to identify the most significant causes of delay and to measure the strength and direction of the relationship between critical success factors and delay factors in order to examine project parties’ evaluation of projects’ critical success and delay factors, and to evaluate the influence of critical success factors on critical delay factors.
A relative importance index has been used to determine the relative importance of the various causes of delays. A one and two-way analysis of variance (ANOVA) has been used to examine how the group or groups evaluated the influence of the critical success factors in avoiding or preventing each of the delay factors, and which success factors were perceived as most influential in avoiding or preventing critical delay factors. Finally the Delphi method, using consensus from an expert panel, was employed to identify the seven most critical success factors used to avoid the delay factors, and thereby improve project performance.

Project management is today a current and highly discussed area. How projects within the construction industry are managed has not changed significantly during the last decades. The construction market, the amount of different actors and the way that projects are procured today has however changed. This has led to a gap between the managerial view on how construction projects should be conducted today and how they actually are executed. This is reason enough to question this conservative industry and look into what possibilities there might be in the future. The Agile project management approach is evolved from the software industry where it has grown and developed through empirical progress. It is suited for large complex projects where it is difficult to specify the product in advance. It is today used in different industries but mostly in the software business where the customer detects their needs through means of repeated tests and improvements to a prototype. This thesis has researched what opportunities there might be in implementing the Agile project management approach in the design phase of construction projects. The major advantages found with implementing the Agile approach is an increase in the client’s involvement. The Agile approach almost forces the client to increase their participation in the project compared to the situation today. It can also decrease the uncertainty and improve risk management. By the use of time management and specific meetings it will also be beneficial for keeping track of the project’s progression and status.Projektledning är idag ett högaktuellt ämne diskuteras intensivt. Hur projekt inom byggbranschen styrs och leds har inte förändrats nämnvärt under de senaste decennierna. Byggmarknaden, mängden av olika aktörer och hur att projekten upphandlas dag har dock förändrats. Detta har lett till ett spricka mellan ledarskapssynen på hur byggprojekt skall utföras idag och hur de faktiskt genomförs. Detta är skäl nog att ifrågasätta denna konservativa bransch och titta närmre på vilka möjligheter det kan finnas i framtiden. Den Agila projektledningsmetoden har utvecklats inom mjukvarubranschen där den har vuxit och förbättrats genom empiriska framsteg. Den är lämpad för stora komplexa projekt där det är svårt att ange och definiera produkten i förväg. Den används idag i olika branscher, men främst i mjukvaruindustrin där kunden upptäcker sina behov med hjälp av upprepade tester och förbättringar av en prototyp. Denna avhandling har undersökt vilka möjligheter det kan finnas i att använda Agila projektledningsmetoder under projekteringsfasen i byggprojekt. De största fördelarna som finns med att använda den Agila metoden är en ökning av kundens engagemang och involvering i projekten. Den Agila metoden tvingar nästan kunden att öka deras deltagande i projektet jämfört med hur situationen ser ut idag. Det kan också leda till minskad osäkerhet och förbättrad riskhantering. Genom användning av ”time management” och särskilda möten kommer de Agila metoderna också att vara till nytta för att hålla reda på projektets framåtskridande och status.

The study is a qualitative investigation of the implementation of green procurement in the construction sector at Local Government level. The focus is on the Metropolitan Municipalities of EThekwini, Nelson Mandela Bay and City of Cape Town. For the purpose of realising an extended comparative perspective, an additional three smaller municipalities were also reviewed. Green procurement is the tool used by governments to source the supply of products and services that are environmentally friendly to counter the global problem of climate change. The study commences with the exposition of the aspects of green procurement from the basis of the enabling legal framework to the scholarly contribution from which the study can be predicated. It becomes apparent from this review of legislation that there is a scope within the existing body of legislation for the use of green procurement as an environmental tool. Scholarly work addresses adoption of green procurement and considers, inter alia, the Bottom-up Approach, the Top-down Approach, and the Procura + Milestones model. Literature indicates that development has a negative impact on the environment, which includes vegetation loss, illegal dumping, and greenhouse gas emissions. Further, the literature recommends green lifecycle design and production of construction projects to reduce the impact of construction on the environment. A systematic investigation of municipalities by means of interviews with relevant municipal officials involved with the procurement of products and services, infrastructure services and environmental affairs officials made it possible to identify factors that impact on the implementation of green procurement. The investigation finds that the major obstacles to green procurement are socio-economic challenges that confront municipalities, lack of policy, and lack of awareness. Recommendations include the proposal of initiatives that encourage and improve the implementation of green procurement. The study hopes to inspire innovation in the implementation of green procurement in the construction sector.

Esta pesquisa foi motivada pela observação de um problema prático com potenciais contribuições teóricas. O problema em questão é a dificuldade de gerenciar projetos complexos de construção de modo que os objetivos estratégicos de sua implementação sejam alcançados, problema observado em um complexo programa de reestruturação urbana na cidade de Porto Alegre. Estudos indicam que nas últimas décadas houve um aumento na complexidade de gestão de projetos que resultou em desafios para as práticas gerenciais tradicionalmente adotadas. Alguns autores relacionam esse aumento de complexidade com uma demanda, cada vez maior, de compreender como projetos estão alinhados com os objetivos estratégicos e como irão contribuir para a geração dos benefícios esperados pelos diversos agentes intervenientes de um projeto. Dentro deste contexto, a falta de suporte dado pelas tradicionais praticas gerenciais é apontada. As críticas focam não só na falta de alinhamento estratégico e na dificuldade de gerenciar interesses conflitantes, mas também na dificuldade de lidar com a susceptibilidade desses projetos ao contexto politico, econômico e social no qual se inserem, e com a dinâmica desse contexto. Dentro deste contexto, foram identificadas duas abordagens gerenciais que emergem no contexto da construção civil em resposta às deficiências observadas: a Benefits Realisation Approach (BeReal) e o Lean Project Delivery System (LPDS). O foco da literatura existente sobre essas abordagens é predominantemente de caráter prescritivo, oferecendo modelos e métodos para sua aplicação. Identificou-se portanto a necessidade de avaliar a contribuição dessas abordagens para lidar com os desafios observados e contribuir para a melhoria do suporte a geração de valor em projetos complexos. Uma terceira abordagem, a Logical Framework Approach (LFA), utilizada no programa onde o problema foi identificado, também foi avaliada, pois é sugerido na literatura que ela oferece suporte para lidar com alguns aspectos da complexidade dos projetos. O processo de pesquisa envolveu as principais etapas de Design Science Research: encontrar um problema prático e com potencial para contribuição teórica, obter um entendimento deste problema, desenvolver ou identificar potencial solução, testar a solução, avaliando sua utilidade, e avaliar a contribuição teórica desta solução. Neste estudo, ênfase foi dada à avaliação das potenciais soluções identificadas. Três estudos empíricos foram realizados: o primeiro teve como objetivo entender o problema - programa de reestruturação urbana em Porto Alegre/Brasil; o segundo para avaliar as contribuições da adoção da BeReal em um programa de reestruturação de um campus hospitalar em Brighton/Inglaterra; e o terceiro para avaliar as contribuições do LPDS em um projeto de um hospital em San Carlos/Estados Unidos. Os três estudos apresentam diferentes contribuições gerenciais para o suporte a geração de valor em projetos complexos de construção. Tais contribuições são explicadas com base em um referencial teórico desenvolvido, formando um modelo conceitual que explica as mudanças necessárias no contexto de gestão de empreendimentos complexos para um melhor foco na geração de valor e como as diferentes praticas observadas e mecanismos de suporte contribuem para esta mudança.This research was motivated by a practical problem with potential theoretical contributions. The problem in hand is the difficulty to generate value in complex construction projects, a problem observed in a large urban regeneration programme in Porto Alegre. Past research indicate that in the last decades there was an increase in project complexity, posing challenges to traditional managerial practices. According to some authors, such complexity is partially due to an increasing concern to understand how project’s outputs contribute to generating change and delivering benefits to different stakeholder groups. Within this context, the lack of managerial support provided by traditional project management approaches is pointed out. Firstly because such approaches generally focus on the delivery of a physical product, within time and budget. Secondly, they do not provide support for dealing with the conflicting interests of multiple stakeholders. And thirdly because they do not properly consider that projects are susceptible to their economic, social and political context and subject to changes in such environment. In this research, two managerial approaches that are being used in the construction industry were identified as having potential contributions to improve value generation in complex projects: the Benefits Realisation Approach (BeReal) and the Lean Project Delivery System (LPDS). The literature available about these approaches is mainly prescriptive. Thus, there is still a need to understand why and how such approaches contribute for value generation. A third approach, the Logical Framework Approach (LFA) used where the problem was identified, was also analysed, as the literature suggests it also offers contributions to deal with some aspects of complexity. This research followed a Design Science Research process: finding a practical problem with potential theoretical contributions, framing the problem and searching for potential solutions, understanding how and why the solutions contribute for solving the problem and analyse the theoretical contributions of the solutions. In this study, emphasis was given to the evaluation of potential solutions identified. Three empirical cases were realised: the first one was in a urban regeneration programme in Brazil, aiming to understand the problem; the second was realised in a healthcare infrastructure programme in the UK, to analyse the adoption of BeReal; and the third in a healthcare infrastructure programme in the US, to analyse the adoption of LPDS. The three studies presented different managerial contributions to support value generation. Such contributions are analysed based on a conceptual framework that was devised. The model reveals the underlying concepts of observed managerial practices that contribute towards the improvement of value generation.

An essential factor adversely affecting the performance of construction projects is the improper handling of materials during site activities. Materials management is made problematic by materials shortages, delays in supply, price fluctuations, damage and wastage, and lack of storages pace. In addition, paper-based reports are mostly used to record and exchange information related to the materials component within a supply chain which is problematic, error-prone, and inefficient. Generally, modem technologies are not being adequately used to overcome human error and are not well integrated with project management systems to make the tracking and management of materials easier and faster. Thus, this research focuses on the development of a mechanism to improve materials management on construction projects through the integration of materials tracking and resource modelling systems. A multi-facetted research approach was adopted. Initially, a literature review on materials management process in the construction project was conducted. This was followed by case studies involving six construction projects in order to investigate current practice in materials management to establish key problem areas and elements of good practice. The case studies also explored the requirements for integrating materials management and resource modelling in project management systems. The case study findings underpinned by literature results were used to develop a real-time framework for integrating RFID-based materials tracking and resource modelling. The framework was encapsulated in a computer-based prototype system based on Microsoft Visual Basic. NET. The prototype system was developed by amalgamation of all the software and hardware chosen such as MS Access (database system), MS Project (resource modelling) and RFID (automated materials tracking) to provide the mechanisms for integrating materials management and resource modelling in the construction industry. Evaluation of the prototype system was carried out by a series of interviews with industry practitioners to assess its appropriateness and functionality. It also established the skills and other requirements for the effective use of the real-time materials tracking system. The evaluation established that the prototype system demonstrated many benefits and is suitable for use in materials tracking and inventory management processes. It is concluded that the prototype system developed can improve materials management on construction projects, particularly with regard to materials tracking and integrating materials utilisation with the resource modelling subsystem in project management applications. Adoption of the approaches suggested in the thesis will enable the construction industry to improve the real-time management of materials on sites, and hence improve project performance.

Current approaches to evaluating the success of construction projects are inadequate in assessing and improving the management of ongoing and future projects. This is concluded from a study of the relevant literature and of construction project management in Sri Lanka and the U.K. The main criticisms of current practice are the ad-hoc nature of the evaluation itself, the failure to properly relate the evaluation: to the original project objectives; to contextual conditions; and to realistic targets derived from historical databases of similar projects. The absence of any such comprehensive database is a particular shortcoming in Sri Lanka. This research work develops and tests a framework for a comprehensive construction project evaluation system that would overcome such shortcomings.The system would help an evaluator generate a specific project evaluation framework depending on the category (type) and stage of the project and the particular purpose of the evaluation. Such a framework would contain criteria of project performance (eg: related to cost, time, quality, safety, satisfaction etc. and associated sub-criteria), hierarchies of 'indicators' by which to measure such criteria and typical target values (and ranges) of such indicators in that category. Such target values are weighted by the specific project profile, based on project priorities and contextual conditions. The sub-systems of the proposed evaluation system are the criteria, the indicators (with typical target values) and an expert system front-end. Supporting 'tools' modules contain techniques for information elicitation, weighting, analysis and presentation. The three sub-systems of criteria, indicators and the expert system were tested. For example, groups of cost indicators and their average values within specific project categories were derived from data obtained from 138 building, 35 roadworks and 38 bridge projects in Sri Lanka. Their validity was tested by their consistency within project categories, by comparison with projects outside the original database and at a Workshop with experts in Sri Lanka. A pilot expert system was developed to demonstrate the viability of integrating appropriate modules. It is concluded that the proposed system is viable and would provide comprehensive and realistic evaluations of the management of construction projects.

This thesis studies the application of system dynamics principles and models to construction project negotiations and schedule. It helps improve the efficiency of the negotiation processes and allows planners to realize the shortcomings of their proposed schedules through showing the relationships and interactions between variables in the processes or the schedules. This research is conducted as an effort to demonstrate the usefulness of the system dynamics models on the construction industry. By developing robust system dynamics models, the efficiencies and the overall performances of the construction projects could be improved as the probability of project delay would be significantly reduced through, much better planning and more efficient negotiation process.

This thesis aims to valuate flexibilities in a large-scale railroad construction project. In general, a railroad construction project involves a large amount of flexibilities due to its long construction period and conflicts among various participants. Therefore, railroad construction projects require investors to examine the feasibility of the project, taking into account managers' ability to make strategic decisions to deal with flexibilities during the construction. However. this important value is not considered in conventional valuation methods, such as Net Present Value (NPV) or Internal Rate of Return (IRR) analysis. This study introduces methods to identify and valuate the flexibilities involved in a project. Decision Tree Analysis (DTA) and Real Option Analysis (ROA) are mainly discussed as primary methods to avoid pitfalls of the conventional valuation methods. DTA helps managers to make future decisions in an effective way by providing graphical diagrams of decision opportunities. ROA appraises the value of mitigating risks by allowing managers to defer investing decisions until a situation that affects a project's success seriously becomes obvious. As a case study, the additional station construction projects in Incheon International Airport Railroad (IIAR) are analyzed to apply the methodologies to valuate the flexibilities. The case study shows that the use of DTA and ROA enables us to visualize the risks, and to quantify the value of flexibilities in the project.

One of the most important, but often overlooked steps in developing a project is a plan to prevent and handle conflict, a Conflict Management Plan. Leading construction experts have identified Productivity, Innovation, Cost Control, Safety, and Litigation Expenses as critical areas in need of improvement in the construction industry of this next century. In the United States alone, $60 billion are spent every year on lawsuits, of which the construction industry accounts for nearly $5 billion. Various dispute avoidance and resolutions techniques are presented that aim to prevent disputes before they arise and minimize the impacts if they do. These techniques are the tools then used in the Conflict Management Plan. A Conflict Mitigation Plan looks at each project individually to establish a set of criteria for controlling conflicts. It assesses how much conflict you will encounter, how severe each conflict might be, then presents cost effective ways to avoid conflict and curb these disputes. Similar to the contract documents it should be complete, unbiased, understood, and accepted by all the parties involved. All of the project participants such as the owners, the owner's representatives, designers, lawyers, and contractors are responsible for designing, reviewing and revising it accordingly. No one person or field should be responsible for developing this plan. Designing a conflict mitigation plan compels the owner to contemplate the conflict that might arise. This will allow the owner to allocate these risks and develop a plan to handle discrepancies. By doing this upfront and with each subsequent review, everyone involved has agreed to follow this plan, reducing the push for lengthy, costly court proceedings. To implement a Conflict Management Plan one must assess the project situation by identifying the sources of conflict that might occur, then analyze the severity and impact each of these conflicts might have. Match the conflict with a corresponding DART, to reduce or avoid the conflict. Draft the plan. Review and revise it as needed.

This paper researches the theoretical background needed for the implementation of literary texts with multicultural themes for use in EFL courses in Sweden and it offers several concrete didactical solutions for multicultural reading. The theory of multicultural education by J. A. Banks is presented with focus on the dimension of knowledge construction. The processes that are examined are the learning processes in the zone of proximal development by Vygotsky (1986), the concept of scaffolding by Woods, Bruner & Ross (1976) and the process of perspective-taking by Thein & Sloan (2013). These processes each employ a three-step sequence that moves students from their existing knowledge to new knowledge and revised personal opinions. The teacher’s role is to provide support during the learning process. The second part of the paper suggests different activities for the multicultural reading of a novel, used to make the process of multicultural knowledge construction and scaffolding visible. Teacher support includes text reduction, book discussion and language analysis. Discussion points found in Love Medicine start with revising the stereotypical images, discovering how personal experience influences knowledge or how ethnicity influences professional career choices. When teachers and students read literary texts with multicultural themes, students’ racial prejudice can be reduced (Banks 2004) and their ethical attitudes become more open (Thein & Sloan 2013). The literary work chosen for framing in the theory is Love Medicine by Louise Erdrich. The paper ends with a reflection over the limitations of multicultural reading projects.

Pełny tekst źródłaStreszczenie:
Project managers have a major role in the construction and completion of projects. Much of their work consists of reviewing, clarifying, and coordinating information required by the field management and subcontractors performing the work on the job site. The assistance they give with the transfer of information helps with successfully completing projects. For many people, the largest indicator that a project was successful is that construction activities were completed on schedule. While finishing on schedule may be the primary focus of those involved with construction activities, projects still struggle to finish on time. The purpose of this study is to find out what construction industry professionals consider important skills, tools, and knowledge for helping project managers finish the projects they manage on schedule. Research results found the general topics of management and scheduling are the most important for project managers to understand. Within the topic of scheduling, the importance of material procurement ranked highest of the specified subcategories. Construction professionals also ranked working with subcontractors, understanding project documents, weekly project meetings, working with owners, and having interpersonal and communication skills as important topics that will help project managers keep their projects on schedule.

Due to their complexity, construction projects involve significant risks thatmust be managed in order to meet the main project objectives in terms of cost,time and quality. While some risks can be foreseen at the beginning of aproject and allocated among the project actors, other risks are difficult topredict. Moreover, even identified risks may change in scope and requiredifferent types of response. In order to manage such risks successfully,collaborative efforts among project actors are needed. This thesis focuses oncollaborative management of risks in construction projects – joint riskmanagement (JRM) – which is claimed to provide several advantages incomparison to separate risk management by each project actor. An overall aimis to increase the understanding of how JRM can be enhanced throughout aproject’s lifecycle.The underlying studies this thesis is based upon constitute a multiple case studyof nine construction projects, a questionnaire survey and a longitudinal casestudy of three construction projects. Empirical data were collected throughinterviews, observations of JRM workshops and document studies. Theempirical findings show that cooperative procurement procedures, organicmanagement systems and appropriate strategies for addressing agency-relatedproblems enhance JRM in construction projects. Thus they require thoroughconsideration when organizations intend to implement JRM.This thesis provides several contributions to risk management theory. Firstly,the author extends the definition of JRM by including its core componentstogether with associated activities and underlying factors. The extendeddefinition better reflects, and increases understanding of, the nature of JRM.Secondly, the research contributes to discussion of serious drawbacks related to traditional procurement practices by identifying and studying procurementvariables (project delivery method, form of payment and use of collaborationor partnering arrangements) that have a major influence on risk management.In addition, the results of questionnaire survey suggest that cooperativeprocurement procedures in general and collaborative activities in particular arepositively related to the use of JRM. Finally, by framing the empirical resultsin an organizational theory context this research identifies two sets of factorsthat strongly influence the implementation and effectiveness of JRM, related tomanagement system (organic vs. mechanistic), and strategy for responding toagency-related problems. By applying theory on mechanistic and organicorganization to RM, the study pinpoints the importance of managing tensionsbetween control and flexibility when implementing JRM. The author suggeststhat JRM requires a combination of formal tools (aimed at controllingidentified risks) and flexible strategies (aimed at responding to unforeseenevents). By investigating how strategies to handle agency-related problems canfoster collaborative relationships and JRM, this research contributes to RMliterature where few studies have discussed JRM from the perspective of theprincipal – agent relationships.Godkänd; 2013; 20131205 (ekaosi); Tillkännagivande disputation 2014-01-07 Nedanstående person kommer att disputera för avläggande av teknologie doktorsexamen.

Broadly discussed in the literature the concept of project success still remains ambiguously defined. The well known success criteria like time, cost and quality does not provide any practical nformation of achieving of project objectives in an efficient way. Identification of main drivers of project success gain particular importance for companies in the light of highly competitive environment.
Housing construction projects represent one of the largest sector in construction industry and Ukrainian housing construction industry is considered to have one of the highest rate of return in EU. However the amount of research related to Ukrainian market is limited to few general economy overviews published by such organizations like World Bank and big consulting firms.
The main aim of this research is identification of the most influential success factors from the 26 factors identified in existing project management literature. The analysis was performed in a highly profitable housing construction industry with a focus on Ukrainian market peculiarities.
A questionnaire survey was sent to 110 experienced housing construction project managers and 26 responses there received. Based on the findings of the questionnaire success factors were ranked according to their impact on project success. In addition success factors interrelationship was studied in order to study the importance of each factor in depth.
The findings of the research contributed both to project management field of study and Ukrainian construction market research. A primary and support areas of success factors were identified which might serve as a practical guide for managing housing construction projects in Ukraine. The most important success factors were defined: economic environment, project manager’s experience and qualification of project team.
Project managers in housing construction industry in Ukraine would probably consider being more aware of the dominance of environment and human recourses related success factors. Additionally, success factors interrelation matrix might be used as a success diffusion map.
Further research might be also essential in this area like studying different types of project and expanding the focus of current study or analysing the importance of success factors on different stages of the project life cycle.

This thesis is about risk management in fast-track construction projects. The aim of the study is to identify the risks in the UAE construction industry, understand how they are dealt with, and propose more effective frameworks for risk management in fast-track construction. A mixed method approach was used to fulfil the objectives of the study. 65 questionnaires were distributed to professionals in the construction industry, including contractors, sub-contractors, project managers and private consultants. Their responses were analysed using statistical techniques, and the results taken for discussion to a focus group of eleven experienced construction managers and experts. Secondary data was also collected via literature reviews of print and website articles, and of books and documents from company, government and industry-specific databases. The findings show that risks in construction projects can be internal or external, and that in the UAE, owner- and design-related risks are seen as the most significant. Knowledge about risk management is present, but more needs to be done to eradicate the problems associated with poorly managed fast-track construction projects. Using the suggestion of the focus group, a framework for risk mitigation was developed based on the Alien Eyes’ risk and Qualitative Risk Management models. The study discusses the implications of risk management for practitioners and academicians in the construction industry. Poor risk management, which is usually the consequence of inadequate recognition of and/or responsiveness to risks and uncertainties, can have a devastating impact upon projects. It is hoped that practitioners applying the findings and suggestions in this study will see positive change, improved profitability and greater competitive advantage as a result.

This thesis investigated the levels of infrastructure construction project stakeholders’ involvement, their influence on quality outcomes, and how improved participation can enhance not only quality outcomes but overall project delivery success. Understanding the current engagement mechanisms and the innate challenges provided a basis for developing a framework, the Quality Excellence Framework (QEF), a framework that provides the foundation for successful quality outcomes, overall project success, continuous improvement and innovation. The research, conducted over three phases, comprised qualitative and quantitative analyses. The final phase, the Focus Group Discussion (FGD), was an endorsement of the QEF by a panel of industry experts.

Pełny tekst źródłaStreszczenie:
The construction industry contributes the largest portion of waste to landfill, and it consumes a significant proportion of mineral resources excavated from nature. Due to adverse environmental impacts of waste generation, as well as financial gains associated with its minimization, waste intensiveness of the industry has remained a major concern across nations. This study investigates the design, procurement and construction strategies for waste minimization, using a dynamic approach. Apart from an investigation of the key and underlying measures for construction waste mitigation, the study considers the interrelationship between stages of projects' lifecycle. This is as activities carried out at an earlier stage are capable of engendering occurrences at later stages of the dynamic project delivery processes. Following the tenets of critical realism philosophy and exploratory sequential mixed method, the study combined qualitative and quantitative approaches at intensive and extensive stages respectively. At the early stage of the study, data were collected through literature review and focus group discussions with industry experts. Results of the qualitative study were used to develop a questionnaire, which was analysed using statistical approach and structural equation modelling. As a means of investigating the key drivers of waste minimization at a holistic level, a system dynamic model was developed to simulate the interplay and effects of different strategies that were confirmed through the previous process. The study suggests that design stage has the most decisive impacts on construction waste minimization. At this stage, the key dimensions for designing out waste include design for modern methods of construction, collaborative design process, design for standardisation and waste-efficient design documentation. Error-free design and involvement of contractors at early design stage are part of the critical success factors for designing out waste. With design being much important for waste minimization, competencies of design in terms of waste behavioural competency, design task proficiency, construction-related knowledge and inter-professional collaborative competency are essential for designing out waste. Materials procurement process could enhance waste minimization by considering its key dimensions for driving waste-efficient projects, which includes waste-efficient materials purchase management, suppliers' alliance and waste-efficient bill of quantity. Efficient materials take-off and take back scheme are confirmed as critical success factors for driving waste minimization through materials procurement processes. During construction activities, waste could be reduced through prefabrication and offsite technology, contractual requirements, maximisation of materials reuse and improved collaboration, among others. Prefabrication, supply chain alliance and collaborative procurement routes are confirmed as the critical success factors for reducing waste during construction process. Dynamic interplay among these sets of strategies suggests that notwithstanding the significance of the different measures during design, procurement and construction processes, prefabrication technology and collaborative procurement route are the holistic drivers of construction waste minimisation. The study implies that designers could effectively drive waste minimization through dimensional coordination and standardisation of design in line with standard materials supplies. In addition to the need for prefabrication and offsite technologies, increasing collaboration among project team is requisite to reducing waste generated by construction activities. By implementing the strategies suggested in the study, substantial proportion of construction waste would be diverted from landfill.

Nowadays, organizations implement projects for many purposes. Using the project as a strategic success factor for project-oriented companies is continuously increasing. However, most of the time, the results are not the same as planned. Some projects fail to achieve their objectives; others are canceled, whereas on some other cases, companies have to re-plan their strategy. Project-oriented companies know that maintaining an ideal and logical balance between the project’s time, cost, and quality constraints can vastly guaranty project success. Therefore, they should switch from traditional project management to modern and advanced project management methodology, which improves project performance and efficiency over its life cycle. One of the most applicable tools used to assess and monitor project performance and thus finding the associated issues is Project Audit, which is a comprehensive and organized assessment of the effectiveness and efficiency of project performance, management, and compliance. In this research, an integrated project audit model is presented that incorporates a detailed design module, which shows the structure of the model, questionnaire module, and a scoring module. The model is developed as an integrated project audit application where the user is easily able to select, plan, implement, and report a project audit. The model’s output consists of two parts: 1) a comprehensive report that shows the project situation in five main project processes and nine project functions. This report presents the project’s score in a specific function and its related process (i.e., planning cost or closing procurement); 2) useful analytical reports and graphs of the project performance. In this part, the model compares the project’s planned and actual time and cost, calculates their variances, and forecasts the final cost and time based on the current performance. The model is validated by using an actual Oil and Gas project to test its workability and capabilities. Three groups will benefit from this model; 1) owners; 2) project managers and project team; 3) general contractors and construction companies. The model helps project owners to identify problems early on and reduce project waste in terms of time, effort, material and costs. Moreover, it provides owners the opportunity to identify the project performance from the cost and time constraints. Also, after using this model, project managers and project team have a list of findings that need to be addressed to enhance the overall project performance. The various reports of the model not only provide detail information about project constraints (time, cost, and quality) but it also present valuable analysis related to other aspect of the project (i.e. risk, scope, and communication) which are very useful for the project team. Furthermore, the developed lessons learned from the project can be documented with this model, which is very useful for general contractors and construction companies in future projects.

Literature usually suggests that construction organization can reduce the costs derived from rework implementing quality management systems. Most common challenges and obstacles that construction organizations face during the implementation process and use of quality management systems are related to "how" the information can be recorded in an effective way, and "what" can be done with the recorded information.
The aim of this dissertation is to focus on improving the defects recording process in the construction industry, and to propose methods and tools to use defects recorded on-site to prevent and reduce rework in the construction industry.
The dissertation starts with the development of a conceptual model used to characterize defects. The current model is based on previously existing models and their adaptation to the context of the Spanish residential building sector. The model is based on the enumeration of the parameters that allow characterizing defects. The final model includes 6 parameters, with a list of standardized words and their definitions.
The pre-established vocabulary lists are based on existing classification systems proposed by recognised organisations, authors and research reports, but then adapted to the Spanish context. However, in terms of defects, no standardised list exists. For this reason a taxonomy of defects is further developed for the Spanish construction sector. The aforementioned taxonomy consists of 15 main categories and 19 subcategories.
The dissertation continues with the development of a methodology to track defects in the construction industry and its implementation in an IT tool called MoBuild. The obtained tracking system is based on images and tags. The strengths the abovementioned tracking system is to record information in a structured way and enable further statistical analysis of the recorded information. The new approach implemented in the MoBuild application allows practitioners to reduce the time of the recording process, facilitating the implementation of quality management systems, such as ISO 9000 in construction organizations.
Furthermore, research proposes a quantitative methodology for dealing with potential adverse quality risks during the pre-construction stages of residential buildings and other similar types of constructions. The strength of this methodology lies in the fact that it helps designers to explicitly consider on-site quality during the design process. Designers can compare several design alternatives during the design phase, and determine the corresponding overall quality risk levels of a construction project without their creative talents being restricted. The methodology is especially worthwhile for those less-experienced designers who lack the required skills and knowledge to recognize quality risks in developing optimal designs.
The methodology also serves as an assessment tool for construction companies. It can be used to measure the potential quality risks of construction projects and its subsequent construction activities. The suggested methodology also allows construction companies to optimize their on-site performance in the quality domain during the planning and preparation stages.
Finally, this dissertation analyses the quality perceived by the end users during the post-handover stage. Different statistical methods are used to demonstrate the usefulness of the recorded data for the construction organizations. The aim is to highlight the essential role that records play in the operation of a quality company, in particular by providing essential evidence of the operation of quality systems.
The aforementioned statistical analysis determines the type of defects detected; the elements affected by defects; the areas where defects are detected; which subcontractors produce defects; the source of the detected defects; the origin of the detected defects and; the influence of the building type and its characteristics in the number of defects detected.

Construction materials cost estimation is considered one of the most important tasks in the development of project budget. Using material hedging to mitigate the risk of material price volatility is a new concept for construction companies.
This thesis matched material hedging with the fuel hedging application utilized by airlines. The weather hedging process was used as a precedent for material hedging application in the construction industry. This thesis developed a model to provide a step by step guidance to apply material hedging in the construction industry. Further, this thesis matched its model with the model presented by Macdonald (2013) and provided a lower level of detail to support actual implementation of material hedging.
Future work in this area could be the investigation of material hedging cost to decide if the hedging application is feasible. Also, validity and reliability of the model presented by this thesis should be investigated.

The 'defects problem' has demanded considerable attention in recent years, with much emphasis given to the technical causes of failure. This research project examines the problem from a different point of view - that of human error. Taking as a starting point, technical publications in the construction industry, the research reviews human error literature from a variety of industries and perspectives and synthesises a model of error causation covering organisations in a construction project context. This model is then progressively tested in four studies, a general preliminary survey and three more detailed studies of house-building. Conclusions support the view that errors leading to failure in complex socio-technical systems often exhibit systems characteristics and involve the whole managerial structure. An improved model is proposed, which emphasises the importance of both project and general management errors.

The value of project knowledge to the management of a current project is considered crucial to successful project delivery. However, knowledge capture and retrieval suffers from a number of deficiencies, which may result in the loss of huge amount of knowledge and difficulties in retrieving captured knowledge. This study aims to develop a reliable framework for the capture and retrieval of organisational knowledge for use in construction projects. Adopting an empiricist methodology, it includes a survey conducted to investigate the current practice, and semi-structured interviews to explore best practice. The results obtained are used as a foundation for a framework that can assist construction companies to avoid the loss of project knowledge and increase performance and innovation in projects. The findings indicate that project review (PR) is the most appropriate method for achieving knowledge capture; in addition, this should be conducted in a systematic and precise way and results should be presented in the form of instructions or in a checklist format, forming short and precise insights. For quick and efficient retrieval knowledge must be categorised based on project management processes and activities, using an IT system with components designed to manage knowledge and locate experts. Nevertheless; the framework developed suggested that regardless of the effectiveness of the approach to knowledge capture and retrieval, without a knowledge-sharing environment the application will not benefit from these methods. Open culture and resources are critical for providing a knowledge-sharing environment and that leadership has to sustain project knowledge capture and retrieval, providing full support for its application. The framework has been evaluated by academics and practitioners who are experts in their field. The results have indicated that the framework and its components are both applicable and effective.

This research examines the micro -political risks affecting international construction projects in Namibia and whether these risks are effectively managed. A case study research design was used for the study and the findings were that key threat risks identified in this context were repudiation, contract problems, labour unrest, hostile press, delay in permit approvals while local ownership requirements and expatriate labour restrictions are both threat and opportunity risks . It further emerged that qualitative (heuristic) techniques were commonly used in an ad hoc fashion for risk assessment and that the risk management strategy of cooperation was the most preferred. In addition, evidence suggest s that the execution phase is most prone to micro political risk. A significant number of the micro -political risks identified arise from the host government, while the balance arise from the host society. These findings are likely to apply to other international construction projects in Namibia and have serious implication s for the role of government in the success or failure of infrastructural projects which are badly needed for national development. Therefore, the Namibian Government can positively contribute through introduction of regulations, laws or amendments to laws that enhance opportunities, minimise downside risk, and thereby reduce overall construction costs on international construction projects in the country. It is recommended that systematic risk management in which both qualitative and quantitative techniques are used for risk assessment, be adopted in dealing with micro political risks associated with international construction projects in Namibia. Additionally, tertiary institutions offering risk management training need to focus on qualitative methods to facilitate maximum benefit when these methods are applied by their graduates. The existence of both threat s and opportunities in the micro -political risk environment in international construction means contractors in international construction need to be on the lookout for downside risks as well as opportunities.
