Full textPurpose: The law of public procurement is used by all governments who procure products, services and public works using tax funds. The purpose of this study is to acquire an overview of how public purchasers’ reason regarding procurement of public works. The aim of this study is to list factors that affect decision-making regarding short and long-term aspects when a public government is to purchase public works, and to acquire an understanding of what personal qualities are needed to undergo a procurement. Method: Literature studies examine how the law of public procurement is designed,and what tasks a procurer has. Further studies are made on how things can go wrong and what the consequences can be if the purchaser undergoes an unlawful procurement. The interviews illustrate practical experience that procurers and property managershave on the law of public procurement, how they go about acquiring their wanted product and their views on what is problematic about this law. Findings: This study shows us that the procurers work is comprehensive and that there is a big risk of doing something wrong in the procurement. Qualities that affect aprocurer’s work include experience, competence and knowledge of the industry. The literature studies show that a bid can be won by the lowest cost, or by the most economically advantageous tender. The latter is determined through analysing soft parameters, such as operating costs, the bidders’ organisation, production times and more. Factors that affect the procurers options regarding short and long-term aspects depends on industry knowledge, configuration of the public procurement law, structure of the organisation, political policies, environmental certifications, type of contracting and the usage of the building. Soft parameters can be difficult to control and can lead to a judicial appeal. What is currently analysed other than price is usually is the organisation of the contractor. Price is always a parameter that procurers analyse and often the only one. Implications: The public procurement law exists to favour competition in the nationand in EU. Some parts of law inhibits procures’ options and can make their work difficult to carry out. How procurers’ reason on choice of qualities of buildings and how they work with evaluating bids are good things to know for anyone involved with the public procurement law. Limitations: This study is limited to public procurers working in municipalities of about 100 000 inhabitants. The interviews are restricted to procurers and property managers. The study investigates how buyers working with procurement of public works reason.

Full textPublic procurement of construction contracts is a complex process that involves both general competence in procurement related to procurement procedures according to the laws of public procurement, and competences in project management to choose contract delivery form, payment form, collaboration form and to design the selection of supplier. A development of the procurement requires that project managers, and procurers, cooperate and are involved in the development process. In order for the two different areas of knowledge to be integrated with each other, it is required that socialization takes place between the roles according to the SECI model. The knowledge also needs to be transferred on a higher, organizational level to develop the procurement work. A prerequisite is that the knowledge is codified so that, according to the SECI model, it can be internalized by other employees within an organization. The purpose of this work is to investigate how the cooperation between procurers and project managers works when it comes to the development of the public procurement of construction contracts and how knowledge transfer can look like in the procurement phase. A case study was conducted with four contracting authorities and empirical data was obtained through semistructured interviews with procurers and project managers in the four different cases. An interview with a representative from The National Agency for Public Procurement was also conducted to investigate how they support the development of the contracting authorities. The data were analyzed with theories of knowledge transfer and knowledge integration. The results showed that the collaboration is affected by how centralized the organization of the procurement function is. The more centralized the organization is, the fewer opportunities of contact are taking place between the roles. This can lead to the socialization process not taking place to a sufficient extent, which in turn can affect the availability of codified knowledge. The work with knowledge transfer varies between the four different cases and can be explained by the fact that they have different prerequisites and resources for achieving knowledge transfer at a collective level. This is also evident in the utilization of the support functions of The National Agency for Public Procurement, where internal resources within the contracting authorities can cover this need for support. On the other hand, codified knowledge in the form of, for example, criteria databases are used frequently by all contracting authorities in the study.

Full textTwo main goals for construction projects are that they should be completed within a certain time frame at a certain cost. To ensure that successful projects are achieved, it is important that the projects are managed so that they achieve the goals where follow-up and reconciliation constitute a main activity. For project planning, Last planner can be used as a method. Activities are planned and categorized according to can and should, which will then generate a plan. Costs are controlled and followed up during the project. Target cost control and target cost design is a method who can be used for control of cost generated in both design- and production process. Planning together with reconciliation has proven to be an important key to success for a structured process. Defective routines and complexity affect the work and make it difficult to control the production for the site managers. The focus of this thesis is to map how the work with following up the schedule and the economic calculation for a project in the production process and evaluate possible improvement opportunities. The aim of this study was to investigate how the work with reconciliation of production costs and time scheduled are performed in the production process for construction projects. To realize this a case study has been done together with a Swedish construction company. Further, the aim of the survey of the working method has been to find out how the work can be simplified. This has led to an investigation into how the schedule could be used for financial management. Another goal with this study has been to contribute to the research on the follow- up process I construction projects. To achieve the aim an exploratory researched has been used. The reason for this was to increase understanding within the problem area. Furthermore, the study has used an abductive research approach as it is based on a theoretical frame of reference and the conducts interviews and observations. The study has also been carried out with the help of qualitative strategy as the focus has been on creating a deeper understanding of the problem area and as data collection requires variation. Data have been collected using literature study, interviews, observation and qualitative secondary data. The study shows that routines and working methods for following up production calculations are defective. In the production process, forecasts are currently the most common way of using financial follow-ups. Forecasts, on the other hand, are not carried out at such a tight interval, usually four times a year, which means that control of the economic situation between these occasions is defective. Work methods for following up production schedules are more explored comparatively. Production schedule and production calculation form the basis for controlling production and have a close connection. By integrating these two bases with each other, it would contribute to the financial outcome being followed up at more frequent intervals and thus give the production management an indication of whether the project exceeds the budget or not. The recommendation for the company is to primarily align the work of the employees by ensuring that there are routines and job descriptions available for work regarding follow-up of calculations and schedules in the implementation process. This would generate in better control of production so that both time and cost targets can be achieved.

Full textSyfte: Byggsektorn har under många år fått utstå kritik för att vara ineffektiv, konkurrensfattig samt ha en hög prissättning. Svenska byggentreprenader behöver därför jobba med sina erfarenhetssystem men tyvärr saknas traditionen och även erfarenheten med att arbeta med detta. Arbetet inom byggbranschen brukar kallas hantverkskunnande. Vilket innebär att fel rättas till så snabbt som möjligt utan att förstå och analysera de bakomliggande orsakerna till felen och på så sätt kunna styra sina produktionsprocesser. Målet med studien är att framställa en teoretisk modell över informationsflöden som skulle kunna effektivisera erfarenhetsåterföringen mellan byggprojekt. Metod: Studiens angreppssätt var genom en kvalitativ fallstudie. Kvalitativ fallstudie valdes på grund av att studien kräver en fördjupad analys av problemet. Rapportens teoretiska ramverk är framtaget från en litteraturstudie där fokus ligger vid erfarenhetsåterföring, knowledge management, incitament och motivation. Empiriinsamlingen bestod av sex stycken intervjuer som genomfördes av typen semistrukturerade och en dokumentanalys. Resultat: I dagsläget används mest muntlig erfarenhetsåterföring från produktionen. Systemen för erfarenhetsåterföring används inte då kännedomen om systemen är bristfällig och information om hur arbetet med erfarenhetsåterföring ska ske är obefintlig. Arbetet med erfarenhetsåterföring sker inte kontinuerligt under projektets gång och har ingen egen skallsats. Det saknas struktur, ansvar och riktlinjer om hur arbetet med erfarenhetsåterföring ska gå till vilket leder till en ovisshet bland tjänstemännen om vad arbetet med erfarenhetsåterföring innebär. Då ingen information har kommit ut till tjänstemännen om hur erfarenhetsåterföringssystemen fungerar eller vad som finns i systemen leder detta till att motivationen med att arbeta med erfarenhetsåterföringssystemen blir sviktande. Konsekvenser: Slutsatserna för denna rapport är att en kunskapsbank ska göras tillgänglig för alla tjänstemän inom företag där erfarenheter rapporteras in och ut. Under projektets gång ska det arbetas kontinuerligt med erfarenhetsåterföring genom möten och det ska finnas en ansvarsfördelning över in- och utrapportering av erfarenheter inom produktionen. Det ska finnas en tydlig struktur och tydliga riktlinjer ute i produktionen om vad som ska ingå i arbetet med erfarenhetsåterföring. En ansvarig person ska finnas för erfarenhetsåterföringen som ansvarar för kunskapsbanken och ser till att relevant information kommer in i systemet. Begränsningar: Rapporten berör incitament och motivation som är applicerbart i alla organisationer vilket främjar ett generellt giltigt resultat. Rapporten avgränsades från eventuella databasstrukturer vilket anses som positivt då mycket tid hade behövts för att skapa mappstrukturer och ordning i modellens kunskapsbank. Detta hade indirekt tagit tid från fördjupandet

Full textIn today's construction industry, communication between contractors and authorities in connection with the authorization process can seem to be unsatisfying. There is currently no unified communication model that could lead the exchange of information between authorities and contractors in construction projects. The main purpose of the study is to identify which shortcomings in communication process are common and suggest actions to minimize them. The opinions of the authorities and the contractors in connection with the communication aspect will provide a basis for the conclusions of the study. The methods used in collecting the results of the study are qualitative and consist of semi structured interviews, participatory observations and case studies. The main idea behind the use of multiple data collection methods is to get a good validity in the study as well as to get a reality-based image of the communication in connection with the authorization process in the building works. The swim lane-diagram method is used to analyse the communication process as well as to present a reliable model that can be used as a basis of various actors in the construction industry when applying for building permissions. Causes for shortcomings of communication by the authorities may be due to high workload of government workers and staff shortages. Communication can now happen in different ways depending on which municipality a building project is carried out in. There is currently a transition in the authorization process from application and processing in paper format to a digitized process. In order to streamline the state process in building projects. Digitization can be used to a greater level than what is being done today. Example of digital measures that can benefit the state process is implementation

Full textAbstract Purpose: The current development in the construction sector is trending towards a required positive contribution to the society in which they're active in order to procure construction contracts in the public sector, for example by contributing to social sus-tainability. Sweden is one of several European countries that stand out in the initiative to further and improve the socially developing work done by companies. Social sus-tainability can be defined as follows: health, education, public safety, government, social engagement and equal opportunity. The aim of this work is to provide perspec-tive and examples of midsized municipalities' thoughts on social sustainability in pro-curement of construction contracts. Method: Literary studies, document analysis, and interviews have been conducted. Together, they embody a case study of three midsized municipalities. The literary studies were conducted in order to create a theoretical framework for the essay. Doc-ument analyses of documents from the municipalities have been a part in the empiri-cal acquisition process. Interviews with representatives from municipal organisations which procure construction contracts have been conducted as part of the empirical acquisition process. Findings: There was a discrepancy between the information provided by the inter-viewees regarding the social demands in the procurement of construction contracts and the political decisions made by the municipalities. The interviewees usually posit-ed that political demands in these procurements were thoroughly lacking or nonexist-ent. Political decisions and established documents showed the opposite; municipal work with social sustainability was very active according to the politicians. Implications: The interest in the question of social demands in the procurement of construction contracts is significant, both from politicians and white collar workers. An expanded communication between the two is of grave importance for the devel-opment in the sector. Limitations: This study was conducted in three midsized municipalities in what used to be the fief of Skaraborg. Regional development in the question of social sustaina-bility may have affected the municipalities in a collective direction without regards to the rest of the country.

Full textMany construction businesses are stuck in old work patterns and procedures due to lack of time, nervousness and foremost lack of knowledge of new technology. Building Information Modeling (BIM) is a computer-aided instrument for the building sector which creates a digital 3D-model of a construction where all the information in the lifecycle of the construction is stored in the model. This entails additional opportunities compared to traditional 2D-drawings and BIM is due to play a huge part in the construction businesses in the future. The purpose of this study is to examine how an implementation of BIM would be realized at a construction company, and furthermore how BIM affects the different processes within the tender stage of the company. To gather appropriate knowledge surrounding the subject a literature study has been ongoing during the entirety of the study. For the purpose of data gathering, qualitative semi-structured interviews has been performed on the construction company Wästbygg and the retail company Cadcraft. Observations has also been performed on Wästbygg to get acquaintance with their current work procedures. To implement a new work procedure with BIM would prove to require engagement and patience from the company. National standards do not currently exist, and this makes the progression more challenging. It is therefore vital for the company to decide a well-defined strategy and goals, and furthermore hand out responsibility to one or two employees on the BIM-implementation. To commence the implementation in the tender stage is a wise decision, the tender stage acts early in the construction process and if a realization of BIM is successful here, the opportunities for further expansion with BIM in the company is more probable. Successful practise with BIM would contribute to a semi-automated quantity take-off and calculation, a simplified information exchange in the tender stage, and a comfortable and appealing visualization for both staff and customer. This contributes to a straightforward and more precise tender stage which will strengthen the company’s competitiveness.

Full textThis paper examines Early Contractor Involvement (ECI), which is a new method of collaboration that is designed to handle complexity in society and deal with the problems in the Swedish construction industry. ECI aims primarily at the involvement and use of the entrepreneur's expert knowledge in the early design and planning phase of the project. This in order to increase the opportunities to ensure that a construction project can be built efficiently, both in terms of time and money.We have conducted a case study of the ECI project deletapp Centralen, which is part of the extensive infrastructure project West Link in Gothenburg. The purpose of our study was to investigate how the ECI concept deals with the problems in society and the construction industry. Through in-depth analysis of interviews with involved actors in the project, we have identified factors that affect the implementation and maintenance of ECI as a collaborative method.In our study, ECI has presented various practical possibilities for our study object, such as innovative technical solutions and efficiency for construction. However, a lot of challenges with ECI have emerged. The results that have emerged are that the initial time when the client, contractor and consultants started work was inadequate. Both theory and results from interviewees point out that the problem of trust, division of work and personal chemistry can be deduced to the very first initial time of the project. However, actors involved were well aware that problems or critical situations would arise, but there were seldom good ways to deal with them. Results in our study also show problems in introducing dynamic processes, like ECI, in an organization that seeks structural arrangements.

Full textThe aim of this study in to increase the knowledge of municipal possibilities and constraints to increase building in wood by examining the municipal planning conditions. Point of departure is that building in wood is a prerequisite to reach the Swedish climate targets of drastically reducing national CO2-emissions. In a case study two municipalities are examined, Växjö and Skellefteå, two municipalities with strategies to increase building in wood and with long experience in doing so. The study explores how contextual planning conditions (project specific and informal conditions) alongside formal planning conditions affects the municipal space of action. The result shows that processes to identify planning conditions and to bridge different perspectives are crucial in order to create a contextual space of action. The result further demonstrates that contextual planning condition withhold the potential to, to a certain degree, create space of action outside the presupposed boundaries of the formal planning system.
