- PostA case study of plastic pipe recycling within Civil Engineering(2020) BILLING, TOBIAS; Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik (ACE); Buser, Martine; Buser, MartineThe basis of this master’s thesis is to investigate how recycling of pipe scraps is currently being handled at NCC and also how the whole system for pipe scraps is currently set up. The aim of the study is to compare this system with the models of circular economy in order to investigate if they are compatible, and to analyse what further measures need to be taken so that the recycling of pipe scraps can be improved and further adhere to the principals of circular economy. In order to acquire information about how NCC is handling pipe scraps today, several interviews have been conducted. Workshops at two different construction sites have been carried out. Attending the workshops were craftsmen, supervisors and subcontractors. To gain further information about how the whole pipe scrap system is set up, interviews have been conducted with pipe manufacturers, and a waste management company. On a separate note, the author of this paper is working at NCC which could increases the risk for blind spots and biased analysis. The results of the workshops and interviews indicate that the current system for handling plastic pipes is not adhering to the principals of circular economy. The reason for this is: 1) Manufacturers cannot produce plastic pipes made from recycled pipe scraps in large enough scale due to material demands. 2) There are currently no profitable collection systems that can maintain the material value of plastic pipe scraps. 3) Rules and regulation fail to create incentives for recycling and circular business models. 4) It is not possible to deploy a green procurement strategy. NCC and the actors who are involved in the recycling process for plastic pipes could further adopt the principal of circular economy by adhering to activities such as: research on sustainable business models for collecting pipe scraps, research in material technology for plastic pipes, endorsement of collaboration between companies involved in the recycling chain and implementation of new rules and regulations.
- PostA case study of the new expansion of the subway in Stockholm.Adopting Build-Operate-Transfer mode in public infrastructure project-subway system in Sweden.(2014) ANDERSSON, PENNY PENG CHENG; Chalmers tekniska högskola / Institutionen för bygg- och miljöteknik; Chalmers University of Technology / Department of Civil and Environmental Engineering
- PostA case study on knowledge transfer at Serneke(2022) Peric, Natasa; Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik (ACE); Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik (ACE); Kifokeris, Dimosthenis; Kifokeris, Dimosthenis; Lind, EmilThe dynamic model of knowledge creation is based on the critical assumption that human knowledge is created and extended through social interaction between tacit and explicit knowledge. Knowledge is created by individuals and is then passed on to the organization through the knowledge spiral. This theory implies that organizations are incapable of creating knowledge on their own. However, many organizations attempt to collect tacit knowledge and transform it into codified information - usually in forms of documents, procedures, and manuals. Therefore, it is essential for organizations to have a well-developed knowledge transfer process to utilize the knowledge that exists within the organization long-term. In the context of the construction industry, there are many different disciplines interacting throughout the lifecycle of a project, making the industry knowledge intensive. Construction typically involves many processes and project participants, which is reflected in the highly fragmented nature of project implementation. A common method of knowledge transfer is to make knowledge explicit and store it in the form of computer programs and databases. Conversely, studies show that knowledge-based systems have difficulty transforming tacit knowledge into explicit knowledge. This study is based on the interest to investigate how a large construction company in Sweden manages knowledge transfer at an organizational level. Serneke, the company studied, currently invests in digitalization and a digital business operational system called VLS, which they believe will improve knowledge transfer in the organization. The study presents challenges with knowledge transfer in the construction industry, as well as challenges with the development of computer programs and platforms from the perspective of knowledge transfer. The results identify important elements in the process of improving knowledge transfer at Serneke. It is concluded that Serneke's investment in the development of VLS is an important step towards improving knowledge transfer within Serneke. VLS will facilitate knowledge transfer as it creates a common information structure across the organization. Furthermore, this study has identified that the SECI theory is applicable to many areas within the organization. Finally, it appears that the organization should work to promote factors that facilitate knowledge transfer.

- PostA Framework for Standardized Logistic Systems in Housing Projects(2018) Forsman, Fabian; Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik; Chalmers University of Technology / Department of Architecture and Civil EngineeringProduction efficiency within the construction industry has been evaluated and criticized the last decade. Supply chain management (SCM) and the logistics of a construction project has been named as on improvement which is necessary for contractors to be able to be competitive and able to handle challenges as decreasing sizes of a site. Several researchers have claimed that the amount of non-value adding work at a construction site is significantly higher than other industries. The concept of Lean construction (LC), Supply chain planning (SCP) and Change management (CM) is widespread but not always connected and applicable on the construction industry. It exists a lot of research on how a construction project should arrange its logistics and production to achieve efficiency. This thesis aims to bridge the gap between research and practice and to explain how a project organization within the construction industry can implement new tools and techniques which previous research has developed. A qualitative method within SCM and CM was chosen. A literature study was conducted together with interviews of practitioners. The focus of the study was mainly on four topics: SCM, LC, CM and implementation strategies. Within these topics were theories such as Just In Time (JIT) and Locationbased Planning (LBP) described. It has been concluded that to be able to implement an efficient logistical system in a housing project does the design group have to get more involved in the logistical planning of a construction project. Furthermore, is it important for the contractor’s site management team to communicate internally to address logistics as a topic during the design phase. Moreover, was in concluded that the site management team could improve the logistical system of a site and production efficiency with already existing tools. Practitioners know most improvements that are recommended by this thesis, but they are not having a systematic approach to handle them. Such a framework was provided from the conclusions of this report.

- PostA Measurement of Logistics Performance(2020) ARAFAT, AHMAD; SALHA, HASSAN; Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik (ACE); Christian Koch; Christian KochLogistic management within the supply chain network plays a significant role in delivering materials and resources to the construction sites. Logistics operations may be unable to achieve efficient deployment of materials due to several factors such as weak logistical plans, lack of cooperation between different disciplines as well as the congestion of traffic. The term of logistics performance came to analyse the effectiveness and efficiency of logistical tasks such as planning, organizing, coordinating, and controlling the materials flow from the extraction of raw materials to the incorporation into ready-to-deliver end products. Since logistics started gaining valuable importance and becoming more prominent, there is an increasing need to measure the performance of construction logistics. Although several methods investigated the measurements of logistics performance, these methods are still aimed to measure it in the manufacturing industry, and little has shown how that could be implemented in the construction industry. Therefore, this master’s thesis has been directed towards introducing variables that could be used as applicable and straightforward measures for logistics performance. Another intention of this work is to show how the combination of measuring the logistics performance and the practices can lead to optimisations of the logistical plan. In order to achieve the aims of this work, the abductive approach has been followed. The work starts with a literature study on the material flow process and the measures of logistics performance in order to provide preconceptions. Thenceforward, a set of interviews have been carried out to collect the needed data qualitatively. Ultimately, but not last, an estimated case has been generated to show how the logistics performance can be measured according to the proposed framework. In addition, the estimated case has been limited to for prefabricated concrete project since this type of projects is the dominant type nowadays. As expected, the proposed framework is able to measure logistics performance when the needed data are available. Measures such as cost and time have, to an extent, the ability to present the logistics performance. Furthermore, the results displayed that poor logistical plan could lead to cost overrun. On the other hand, various challenges in the construction industry prevent it from achieving a good logistics performance. Therefore, a simple change in the transportation schedule has been conducted in the purpose of optimising the logistical plan. The results of this change exhibited a significant reduction in the logistics cost. Moreover, the interviews showed that several philosophies such as Just-In-Time and Lean should be applied to make the construction industry able to dispose of its logistics poorness.
- PostA personalization approach for complex decision-making, The case of contract strategy selection at Akademiska Hus(2016) GRUNNESJÖ, MARTIN; GODFREY, NEDRICK; Chalmers tekniska högskola / Institutionen för bygg- och miljöteknik; Chalmers University of Technology / Department of Civil and Environmental EngineeringIn an industry characterized by uniqueness, organizations in construction are put under great pressure to have decision-makers that can deliver unique solutions, often without experience from previous efforts. This work was carried out in collaboration with Akademiska Hus, which is one of the biggest real-estate companies in Sweden. The work aims to find the influencing factors in the choice of a contract strategy. This report also aims to examine the similarities and differences in the process of selecting contract strategy in projects across regions at the Akademiska Hus. Another purpose is to explore how the in-house knowledge base is shared and moreover explore the potential for a personalization approach to facilitate the process. As empirical evidence, twelve interviews have been conducted with project managers across regions at Akademiska Hus. From the results, it can be seen that factors influencing the choice of a contract strategy falls under the three categories; client's objectives, projects characteristics and client comparative advantage. The results also show that Akademiska Hus does not have a standardized approach or models for deciding upon a contract strategy. In addition, the process of deciding on a contract strategy varies a lot between regions. There is a wide in-house knowledge base within the organization. However, Akademiska Hus lacks effective cross regional knowledge sharing mechanisms thus the knowledge base is not fully utilized in enhancing the contract strategy selection process. The thesis highlights a potential of a team-centered decision mechanism when deciding on a suitable contract strategy, enabling project managers from different regions to participate. Through a group-based decision-making mechanism, individuals would be able to share their knowledge and thereby increase awareness of the consequences of decisions. In this way, the organization's ability to select the contract strategy would be enhanced.
- PostA practice perspective on knowledge sharing between projects A construction case study(2018) Nilsson, Anton; Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik; Chalmers University of Technology / Department of Architecture and Civil EngineeringOrganisations competitive advantages and ability to compete in the business arena is recognised to be highly related to organisational knowledge and knowledge management (KM). Knowledge sharing between projects is essential for project-based organisations to prevent that knowledge gets isolated in separate projects. The purpose of this thesis is to evaluate knowledge sharing practices at a case organisation and the aim is to provide the organisation with two proposals of KM initiatives, which could improve between project knowledge sharing practices. This qualitative study takes a practice perspective on knowledge sharing between projects in a construction organisation to identify practices and underlying social dynamics affecting these practices. The theoretical framework derives from practice theory and is used as a lens of inquiry when analysing the interview and observation data. Two normative and co-dependent practices are found to permeate the organisation and to be affecting knowledge sharing practices between projects, searching and involvement. Both of these normative practices are found to be of mainly informal nature and highly related to the social and cultural context. Within the organisation, four knowledge brokers are identified to be highly related to the organisational knowledge sharing. These brokers are found to facilitate the normative sharing practices and is utilising both informal and formal arenas. Several of the formal arenas is found to facilitate the two normative practices and enable the development of informal sharing practices and connections between individuals in the organisation. In order for KM initiatives to be successful, the organisation needs to evaluate practices and understand the underlying social dynamics to align the initiative with the organisational conditions. The findings of this study provide the case organisation with the basis for two KM initiatives and further highlight the importance of practice from a KM perspective. This thesis adds to an area which is receiving limited attention and offers a starting point for future researches to evaluate practices in other organisations or industries.

- PostA Swedish contractor’s view on incentives for environmental classified construction(2018) Karlsson, Axel; Edeland, Fabian; Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik; Chalmers University of Technology / Department of Architecture and Civil EngineeringSustainable construction has become increasingly important to consider for all stakeholders in the industry, but also for many users. As a result, more and more environmentally certified buildings and districts are demanded. Many companies see competitive advantages in being associated with sustainable construction and see financial gains while improving environmental work in society. The purpose of this report is to investigate the driving forces and barriers that exist for entrepreneurs in the industry. The essay will also examine which collaboration and construction methods are best suited for success with environmental certification projects. The report is based on a literature study and a qualitative interview study. Economy and time are represented as the main drivers and barriers. It can be added that there is generally a consensus among respondents about an entrepreneur's view of environmental certifications. It is more advantageous to certify a commercial property where users can profile themselves in promoting environmental work. Large companies demand environmentally certified buildings more than private individuals do. It can also be determined that the quality of the detailed design is more important and has a greater impact than the type of construction applied.
- PostA Total Cost Analysis Model of Construction Logistics Solutions Comparing Direct Delivery and Delivery via a Construction Logistics Center at JM(2021) OSSIANSSON, FILIP; ÅSTRÖM, ELIN; Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik (ACE); Sundquist, Viktoria; Sundquist, ViktoriaThe construction industry has challenges in increasing productivity and at the same time keeping production costs down in comparison to other industries. The construction industry also entails a high environmental footprint due to choices of materials and the many materials deliveries necessary for building completion. Rearrangements of construction logistics and implementing supply chain management (SCM) provide possible solutions to these issues. As part of gaining control of the supply chain and reducing the number of deliveries to the site, Construction Logistics Centers (CLCs) are increasingly being used. The aim of this study is to develop a total cost analysis (TCA) model to evaluate two logistics processes of materials delivery to construction site: Direct Delivery or Delivery via a CLC. A reference project at the Swedish construction company JM provides data to the TCA model. The TCA model examines costs in relation to logistics activities from the point of materials leaving the supplier to being placed at the assembly area at the site. The cost data in the TCA are gathered from JM’s framework agreements with suppliers and the CLC-operator. The activities identified in each logistics process are gathered from observations as well as the framework agreements and information from involved parties. The study contributes with a TCA model for different logistics solutions and batch sizes where the TCA itself provides insights of how logistics operations are organized and the costs they entail. The study shows that JM through the implementation of a CLC and the subsidiary JM Supply (responsible for on-site logistics) has taken successive steps towards more efficient SCM. The study contributes to the understanding of the effects of implementing a CLC. The results from the TCA model shows that due to the present supplier agreements and logic of batch sizes, the most cost advantageous logistics solution at JM is the direct delivery to site. However, it should be noted that costs differ significantly in relation to various material types. The TCA model also illustrates that the number of transportations to site decreases with the implementation of a CLC, which is considered a benefit. Thus, to reach the full potential of a CLC solution, JM needs to align purchasing, production, and logistics processes further by taking a holistic perspective of value creation. The research results support JM’s future decision making about the design of their construction logistics solutions as to increase productivity and improve market competitiveness.

- PostAddressing Existing and Changing Roles in the Construction Industry. Current and Future Transformations of Professional Roles toward Fulfilling Industry Demands.(2023) Burtcev, Leonid; Omiwole, Damilare Daniel; Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik (ACE); Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik (ACE); Kifokeris, DimosthenisThe Construction industry is currently buffeted with continuous transformative processes and demands, the like that has never been experienced before. The subject of the resulting change in literature has been explored relatively sparsely, the introduction and evolution of digital technologies and sustainability thinking and their increased propulsion for the AECO in terms of upgrading existing skills, responsibilities, and competencies to meet new norms and recommendations made by society, clients, and regulatory organizations in the industry. In addition, there has been existing research speculating how the construction practice would be in the future, including outcries of new engineering competencies that would be needed in the near future. Nonetheless, there has sparsely been in-depth work to determine how individual professional roles are being altered through their adaptation to the various industry change processes. This study provides a foresight of how professional roles in the construction industry will be developed. In addition, the study will help ascertain from a historical viewpoint through literature and experience of active professionals the trends and changes in their work experience in the Swedish AEC industry over the years and the various drivers influencing these changes. Following a comprehensive literature review combined with deductive analysis of the empirical data from interviews, a mind map was developed to demonstrate findings and analyze how professional roles are perceived to develop in the future. Through the findings of this study, we could redefine the development of roles as a progressive process that is first depicted by new ways of working and new responsibilities, upon which the growth on either of these fronts would require that a new entity become accountable for the new responsibilities, and independent of existing roles. The findings show that digitalization, sustainability, and collaborative working practice have contributed to future role development. Meanwhile, achieving the industry goal of being more efficient, enabling digitalized systems, adopting more sustainability solutions, and becoming data-driven serves as drivers of change that influence professional roles in the industry. The study’s conclusion will provide insight into the future expectations of stakeholders and policymakers for managing change processes in the Swedish AEC industry. Especially by implementing strategies to upskill professionals’ IT competencies, automate routine tasks, increase sustainability or circularity engagements, share common operating databases, and facilitate interaction between these development pathways.
- PostAddressing the challenges of developing a socially sustainable urban district A case study of Frihamnen(2017) BENGTSSON, ANNA; GRANBERG, ANNA; Chalmers tekniska högskola / Institutionen för bygg- och miljöteknik; Chalmers University of Technology / Department of Civil and Environmental EngineeringDue to growing segregation and inequalities in Gothenburg, issues concerning social sustainability have gotten increased focus in the ongoing urban development project RiverCity Gothenburg. The Frihamnen district is part of the project and some of the main objectives for the district is to create a diverse area, accessible for everyone, with socially mixed housing and a variation in activities and business. The purpose of this master thesis is to address the important aspects to consider when working with social sustainability in large urban development projects. The study is a qualitative study with an abductive approach with the Frihamnen project as the case study. A set of ten interviews and one observation constitute the results of the study. The results were thereafter discussed in relation to the developed theoretical framework. The identified challenges and hence important aspects to consider when incorporating social sustainability in urban development projects were concluded to be a collective development of the area, having predefined demands, managing the different actors to collaborate, having a supportive municipal organization and creating defined and measurable targets.
- PostAn analysis and investigation of warranty rework and costs Case Study of a Swedish Contractor(2017) DAEBES, MUNTADAR; YILMAZ, OGUZHAN; Chalmers tekniska högskola / Institutionen för bygg- och miljöteknik; Chalmers University of Technology / Department of Civil and Environmental EngineeringThe purpose of this thesis work is to identify the warranty work and aftermarket work that the case company faces. In recent years the case company has met an increase in the warranty work. The master thesis has been carried out in a Swedish contractor and is limited with remarks from warranty inspection protocols and data collection for four apartment projects. The study is based on interviews with senior executives in the case company. The results in this study show that the three most common defects that occur during the first two years are as follows: cracks on walls/ceilings, cabinet and boxes and doors. This three building parts account for 55.5% of the total number of remarks, based on the warranty inspection reports. The study presents appropriate improvement work to avoid the emergence of the warranty work and to facilitate the follow-up of the warranty work. The main reasons for warranty remarks are based on several different conditions. The causes can be attributed to moisture-related movements, lack of care and maintenance, assembly errors and lack of product selection. The design phase has the major role when it comes to rework. This in turn led to quality errors to occur. Furthermore, the pressure of time in the construction sector has an impact in the result of quality shortcomings. Construction companies are willing to be done in a shorter time than they really need. This naturally leads to stress at the last stage and leading to shortages at the end of the handover of the residence. A closer relationship between the internal organization and the site manager is needed to solve aftermarket problems in a more efficient way. Most of the experiences learned from previous project are not delivered inside the organization, it rather stands with the specific person. Therefore, it is important for the companies to gather information and experience from previous project and deliver it to the project organization. Companies should have strategies to encourage further training so that individuals get better knowledge of the working methods. In order to prevent defects and mistakes during the production phase, experienced personnel from the production management should be involved in the early design phases.

- PostAnchoring Construction Planning in Production(2016) Viklund Tallgren, Mikael; Chalmers tekniska högskola / Institutionen för bygg- och miljöteknik; Chalmers University of Technology / Department of Civil and Environmental EngineeringWith the rising complexity of construction projects, the need to manage this complexity rises. The complexity comes both from the rising amount of subcontractors involved in projects as well as more complex solutions. To mitigate this complexity planning is vital, but as commonly seen in construction projects, few finish on time or on budget. This could in part be identified as a result from the project organisation, where the amount of subcontractors affects the information dissemination and the reliance on the production schedule. Traditionally construction projects employ specialist planners to do the scheduling, this creates distance between workers and the schedule and thus a distrust of the schedule. This leads to the use of the schedule as loose guidelines. In this research one way of countering this has been to include the formen of the contractors in the planning process. By breaking down the project into physical locations and making the participants identify the activities for their contract in each location, the basis of the schedule is anchored and produced collaboratively. By using a collaborative planning session and sequencing of the activities the schedule is anchored. As identified in this research the use of building information models (BIMs), would support this process and help furthering the collective view of the project and help in reducing problems with information filtering through the mixed use of resources such as BIM, drawings and specifications. As it is today planning softwares do not support this kind of scheduling directly from the model. From these described problems a software solution is mapped and a proposed as well as introduced in relation to the planning method.
