- PostA questionnaire survey study of the building industry’s attitude towards social sustainability in Sweden and Chin(2017) Zhang, Jingxuan; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and EconomicsIn today’s construction industry, there are much research and studies on environmental and economic sustainability, but the topic of social sustainability often lacks attention. The concept of social sustainability covers a large area, and it is hard to define. This thesis has studied different frameworks of social sustainability and has provided measurable criteria of social sustainability. The criteria were used to analyse the building industry’s current attitude towards social sustainability development in Sweden and China. In other words, this thesis tried to find out social related problems that the construction industry is facing, and the measures that the industry has taken to reduce the impact of social problems. Since the thesis studied a large-range topic in a large industry, a quantitative method was used in this thesis. Survey questionnaires regarding social sustainability development were sent out to companies in the construction industry in Sweden and China. The companies included architecture firms, consultant companies, contractors and real estate companies. The questionnaires were sent out by Survey Monkey, and the answers were analyzed by using an Excel spreadsheet. The results showed that in both Sweden and China, companies had personnel that were dealing with social sustainability related issues. However, the Swedish construction industry and the Chinese construction industry perceived that the face different social sustainability related issues. The companies in Sweden and China took different measures to reduce the social impacts. The results of the thesis can be used as a benchmark for future development of social sustainability in both countries. Because the society of China and Sweden are different, the results from the two nations were not meant to be compared or use one as a benchmark for another one.

- PostAdopting a business model perspective for sustainable building(2017) Vasudev, Badi; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and EconomicsThe importance to sustainability in building sector become important mostly because of more energy consumption and usage of resources in construction of buildings. Business models with proper key elements for sustainable buildings has the capability to reduce the negative impact on environment and raise the economic and environmental benefits. But there are many challenges in order to achieve goals, for this a wide research is necessary on both business models and sustainable buildings. Therefore, the aim of the thesis is to investigate business models, sustainable buildings and subtopics related to these tasks and develop a new business model for sustainable buildings with considering different views from both literature and case studies. In order to achieve, a qualitative method with an inductive approach is used to conduct the study. For this, two research methods are used in the process. Firstly, a literature review has been done on following topics such as business models, business model innovation, sustainable buildings and sustainable development. Secondly, from the case study research four case studies are selected and divided into two types those are individual buildings and companies. From the literature and case studies key elements are identified and designed a new business model. The new business model has four main elements: sustainability, innovation, networking and value proposition, and sub elements are: energy efficiency methods and environmental care; design, IT support & tools, and innovative architecture; key stakeholder identification and customer and employee satisfaction; and newness. Sustainable buildings with economic gains are challenging to achieve. However, sustainable buildings add value to the society and economic benefits can be achieved in the long-run. This new business model can be basic guideline for start-ups, small scale companies and for future research.
- PostAn exploration of the economic impact and project process influence of BREEAM certification on commercial properties(2023) Andersson, Daniel; Sterner, Erik; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and Economics; Bosch-Sijtsema, Petra; Bosch-Sijtsema, PetraThe growing emphasis on environmental responsibility has prompted industries, including commercial real estate, to reassess their standards and practices. This transformation has led to sustainable properties gaining prominence in this evolving landscape, particularly in Sweden, where certifications have become an industry norm and integral to construction projects. However, these implementations of environmental certificates such as the Building Research Establishment Environmental Assessment Method (BREEAM), have led to various challenges for the project leaders in the construction process, impacting both finances and processes. Acknowledging this shift, this study therefore delves into the economic impact of BREEAM certification on commercial properties, including investigating the economic value of commercial properties, as well as exploring the potential increase in economic value from BREEAM. Moreover, the report also discusses the challenges associated with the certification process, including increased complexity and additional work, but also management strategies to manage the implementation. This was enabled through an inductive approach and a qualitative research strategy, including semi-structured interviews with key stakeholders on a large construction company which delves deeper into one of their projects. This study in the Swedish context implied that contrary to previous literature, BREEAM certification's economic benefits, such as price and rental premiums are minimal, emphasizing the predominant influence of external drivers and highlighting administrative and hidden costs as primary contributors to the overall cost of BREEAM certification on commercial properties. It was further identified that the implementation of BREEAM certification in commercial office building construction significantly increases workload and complexity, demanding early planning, effective management strategies, and leveraging the experience of project stakeholders, underscoring the importance of addressing the complexity for successful project performance

- PostBusiness Strategical Proposals for Implementing Reused Windows in Industrial Construction(2022) Boman, Cassandra; Kruners, Nike; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Löwstedt, Martin; Löwstedt, MartinIt is known that the construction sector accounts for a sizeable share of the total waste generated annually. With various climate targets pushing towards sustainable development, this sector needs to become more circular. Reusing materials and products is seen as having a great potential in reducing the amount of waste and negative environmental impacts the sector has today, although this is often easier said than done. Windows are considered to be one of the more complex components to reuse. In addition, the conditions for implementing reused windows differ depending on the type of construction process and building. The aim of this master thesis was to identify the conditions of using reused windows into newly produced, prefabricated multi-family dwellings, in order to present business strategy proposals for companies within this area of business. A literature review was conducted to understand what barriers currently exist and to identify main stakeholders that are to be involved in the development. The theoretical framework was used as a basis for the interview study which consisted of 10 interviews with stakeholders from different parts of the construction value chain. The interviews were categorised to answer the question of which stakeholder should drive the change, what business changes are required in the studied company, conditions on how windows can be reused and how it can be applied in prefabrication. The results showed that there is no single actor taking sole responsibility, as the whole sector must embrace this reform. However, the actor that will have a major influence towards the implementation of reused windows in prefabricated production are the client. The results also showed that large parts of the buildings that will be dismantled in the near future have windows installed that will not meet the current requirements. Further, the results also showed evidence that the main obstacles are not related to prefabrication but occur much earlier in the value chain. However, obstacles that needs to be addressed concerning prefabrication is increased time- and cost aspects regarding uncertainties of attachments and design changes, as a result of the standardized and otherwise effective lead times. The conclusion drawn presents business strategy proposals for improvement potentials to facilitate the reform towards using reused windows in prefabricated production. The proposals concern internal business initiatives, prefabrication, and sectoral collaboration. Finally, suggestions for further research on the topic are discussed.
- PostClashing institutional logics and its consequences for communication A study of managers in a Swedish cross-cultural mega project(2021) Fischer, Frida; Bergfeldt, Fredrik; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Gluch, Pernilla; Gluch, PernillaThe globalization has served as a ground for government bodies to procure, and construction industry companies to expand beyond their national borders. The public infrastructure client Swedish Transport Administration (STA) have over the last decade introduced strategical aims to advertise their procurements globally, and the efforts have resulted in an increasing presence of foreign contractors in Sweden. In these projects, challenges such as cultural communicational clashes can arise. The responsibility to manage these cross-cultural communicational clashes are not a designated responsibility. However, managers must deal with cross-cultural communication on a daily basis. These challenges have been studied in the Västlänken project, a mega infrastructure project between the client, STA, and foreign contractors. The thesis aims to investigate the communicational challenges present between STA managers and foreign contractor managers, as well as how client-contractor contracts can be improved for cross-cultural communication. The aim was realised through 12 semi-structured interviews with involved managers and two expert interviews. The interview findings were analysed with the theoretical lens of institutional logics. The analysis revealed a set of 20 clashing and aligning managing institutional logic pairs amongst the managers. Ten of the identified logic pairs were aligning and ten were clashing. It was found that clashing institutional logics have a predominant negative effect on communication. The analysis further showed that both STA managers and foreign contractor managers have revaluated some of their own previously clashing logics, which indicates that logics can align over time. This inevitable mixture of clashing and aligning logics is an ongoing hybridization which have developed from the managers earlier managing logics. However, it was found that institutional logics can have national affiliation and that some logics will not change.

- PostCollaborative Learning and Innovation - A Way to Overcome Inertia in Construction(2019) Sörensson, Hampus; Wu, Peiyu; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and EconomicsThe purpose of this research is to explore the reasons for low rate of innovation and their corresponding resolutions in the Swedish construction industry from clients and consultants perspectives. Various practices of collaborative innovation, i.e. product/service innovation, process innovation, organization innovation, have been observed. Qualitative interviews with academic experts, consultants and clients in the industry were held and were compared to literature. By applying Absorptive Capacity framework (ACAP), a comprehensive understanding of innovation development and collaborative learning in case study organizations was obtained. Essential role of factors in ACAP, such as social integration mechanism as well as transformation and exploitation, are recognized. The findings focus on the issues attributed to production dynamics, as opposed to market dynamics, where characteristics of the construction process, namely project organization, unique project and long project horizon contribute to inertia. Furthermore, collaborative practices that may resolve the inertia are found to be knowledge flow, innovation leaders, innovation arena and collaborative business relationships. In addition, digitalization and long-term financial and environmental sustainability are identified as main drivers of collaborative innovation.

- PostContractor-supplier relationships in the construction industry - A case study(2016) Nikinosheri, Roham; Staxäng, Filip; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and EconomicsThe supply chain in the construction industry includes several actors, influenced by the project-based nature of the industry. The majority of studies concerning the interactions and collaborations between actors to improve the supply chain has concerned contractors, subcontractors and clients and resulted in developed procedures, such as partnering. However, the relationship between supplier and contractor has generally not been mentioned in those cases even though this relationship has a substantial impact on the supply chain process. This thesis aims to analyze possibilities and suggest recommendations to improve the supply chain process with an enhanced collaboration between supplier and contractor, by studying the relationship based on high-involvement relationships. The empirical findings are based on a case study of the relationship between a supplier and a contractor in the construction industry. A total of 11 interviews, distributed between the companies, has been conducted and constitutes the data on which the case study is based on. The studied relationship possesses several aspects of a high-involvement relationship without a formal mutual strategy. It was found that the fundamental feature of the relationship was social bonds through personal relations. Additional bonds such as knowledge-based bonds, technical bonds and legal bonds should be increased to enhance the high-involvement relationship. In order to implement a long-term orientation and commitment mutual long-term agreements should be created. Those agreements should be formalized in accordance with intermediate partnering in long-term, but in short-term partnering is not realistic to implement in the examined relationship. By increasing the influence of the supplier, through adding services and procedures to the range of their supply, the relationship and thereby the supply chain could be improved.

- PostDEPARTMENT OF TECHNOLOGY MANAGEMENT AND ECONOMICS DIVISION OF SERVICE MANAGEMENT AND LOGISTICS CHALMERS UNIVERSITY OF TECHNOLOGY Gothenburg, Sweden 2021 www.chalmers.se Report No. E2021:070 Innovation through Early Contractor Involvement A comparable case study of Swedish infrastructure projects and their contractual disposition(2021) Bergström, Tom; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Bosch-SIjtsema, Petra; Bosch-Sijtsema, PetraThe use of Early Contractor Involvement (ECI) has gained increased attention in the construction industry as a means to remove the separation of projects’ design and construction, thus integrating the contractor’s expertise and knowledge in early planning and design work. The benefits seen thereof are numerous, including an improved time- and cost certainty, improved risk management and improved buildability. Another benefit commonly acknowledged is a larger opportunity for and increased innovation, yet current studies of the ECI-concept and its links to innovation have given little attention to how the projects’ contractual disposition affects innovation. Thus, this study has investigated this seen knowledge-gap through a qualitative comparable case study of two current ECI-projects within the Swedish infrastructure sector. Moreover, the study has also in a broader perspective investigated the perceived benefits and hindrances seen through ECI-implementation, as well as the challenges seen through the use of target cost principles and economic incentives. Focus has been placed on the projects’ initial planning and design phase and empirical material was gathered from interviews with both projects’ respective client and contractor organisations. The most notable benefit seen through ECI-implementation was the integration of the contractor’s expertise in planning and design, thus allowing considerations of the contractor’s input in both decision-making and design development. The hindrances to achieving all ECI-benefits were concluded to stem primarily from the lack of equal commitment and the lack of a compromising attitude among the projects’ participating organisations, primarily grounded in accustomed client and contractor roles. These cultural aspects were also seen to create challenges in the projects’ target cost processes, in which client and contractor interests pre target cost agreement were seen to stand in conflict with one another, hence creating large difficulties in reaching agreements which both parties perceived as fair. The difficulty in equating the client and contractor’s economic interests in the planning and design phase was also seen as impeding an increased level of innovation in both projects, and when paired with a lack of economic incentives for innovation efforts, instead created unwanted incentives as to hide innovative solutions till post target cost agreement at which the contractor was also economically reimbursed for such efforts.
