    Entreprenörens risker vid övergången från utförandeentreprenader till totalentreprenader!: En nulägesanalys som skildrar entreprenörens perspektiv i väg och anläggningsprojekt.2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    When clients more often choose to transfer from” traditional” design-bid-build contracts to design-build contracts it creates consequences of risks and possibilities for all involved parties. In collaboration with Skanska as a case company and their division “Väg och Anläggning i Väst”, this thesis was conducted as a qualitative study with the intention to examine what consequences it have on the contractor when an increased amount of contracts transfer from design-bid-build to design-build.

    This thesis shows that the contractor agrees that there are some difficulties with design-build contracts, and that the transition from design-bid-build to design-build takes place in a relatively short time, also that the contractor and the client lack the experience and skills required to perform a good project without major complications.

    Many of the problems that occur today can be derived to individuals and their communication skills, by increasing cooperation and open up for a better dialogue between the parties, which creates opportunity for both the client and the contractor to gently adjust to the changes that the transition to design-build contracts means.

    An Increased cooperation and a more open communication, will result in better working conditions and a better end product.

    Framtagning av korrigeringsfaktorer för enhetstider och kapaciteter: Ett sätt att öka kvalitén på Skanskas normallägen.2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Skanska is using work schedules that are specifically designed for employees in the production. These work schedules are called best practice. These are guides containing technical descriptions, design references, capabilities, etc. for work activities. This support function facilitates the work preparation and planning of future work. For placing unbound base course, there are only few capacities specified in the best practice model. The possibility of correcting the capacities is considered to be minimal. Hence, Skanska has requested to supplement the best practice with correction values based on factors that affect it negatively. With the correction values capacities can be used for similar projects.  The purpose of the report is to assess an approach taken to produce correction values. A general process model was used to produce correction values. The model follows four steps to generate correction values ​​using reported production data. By collecting data, categorize and process the data, correction value can then be calculated. The model's second step categorizes the production data by similar factors. An average correction value can then be calculated for every category. During the study, it has been clear that the production data must contain the right information to allow categorization of data. In order to verify and ensure the right information is provided, own follow-up forms can be designed. The focus of the follow-up forms is to answer questions that enable a categorization. The study examined road-width and settlements as influencing factor in placing unbound base course.

    Nordic and Baltic Case Studies and Assessments in Enterprises - CREDIT Report 22010Report (Other academic)
    Abstract [en]

    This report summarizes 28 case studies addressing the common interest for indicators in case studies in Nordic and Baltic countries and is distributed to different building types

    – Benchmarking systems and indicators (4 case studies)

    – Offices (7 case studies)

    – Housing (8 case studies)

    – School and nursery (5 case studies)

    – Shopping centres (3 case studies)

    – Hospital (1 case studies)

    There are some good practices for benchmarking in large scale. At the moment, those are addressing mostly process and investment indicators, and do not yet cover performance indicators. Front-runner enterprises are already recognizing the potential of benchmarking, rating to highest class may increase interest from investors and building owners. Otherwise, some national and international rating systems are available in the market.

    Few frontline owners are already using cost and performance indicators in daily operations, such as Senate Properties in Finland and Statsbygg in Norway. Their focus is mostly directed to investment, costs, and energy efficiency. Altogether, it seems that systematic procedures are needed in the industry for evaluating performance and compliance to end result to needs.

    There is no commonly agreed or standardized global or European Key Performance Indicator system, but some national and international rating schemes are available. During the past five years a number of rated buildings has grown greatly, and motivation for using those is increasing.

    Market signals are also showing paradigm shift towards end user involvement, and standardized methods for involving end users and making continuous monitoring of satisfaction should be agreed. When committing end users, they need help in order to be able to contribute in value adding way. Workplace management in office buildings is used for tailoring spaces better to end user needs. Senate Properties in Finland develops services where spaces are a strategic asset that can help to contribute an organizational change.

    National and international indicator systems do not cover all important business matters and companies are developing their own systems. Some contractors have been developing national systems for process performance monitoring. Indoor environment is important in shopping centres, and performance level for spaces is an opportunity to owner to enhance cash flow through rental agreements. In the future, building automation systems could provide real-time monitoring of performance indicators continuously contributing changes automatically to reach desired performance.

    Organizations are looking for an indicator system that could help them to measure and enhance performance of buildings. Apparently some indicators are more important than others; regulations for accessibility have become tighter, location is still the core driver, common interest towards operations and reducing annual energy consumptions is growing. There is potential to improve energy efficiency of buildings. Indicator systems should be implemented in tools to encourage usage in projects; those processes are now rather manual. Building Information Models (BIMs) may be suitable tool for managing those more automated way. Based on findings in CREDIT project, offices and shopping centres are most attracting building types in terms of benchmarking.

    Enterprises are benchmarking indicators to some extent but systematic process has not yet been developed and a uniform indicator system considering also building performance and value creation is missing. CREDIT project has increased understanding on indicators and transparency and industry needs more research on this matter.

    3D-visualisering i mark- och anläggningsprojekt.: En studie utifrån Veidekkes förutsättningar att implementera 3D-modeller i produktion.2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Due to the digitalization the construction business is increasingly striving against more digitized tools and working methods. Presenting projects in 3D has therefore become a hot topic where several actors are trying to implement 3D not only in the design phase but also in the production phase. Earlier research dealing with the subject largely chooses to focus on the building construction process and highlights the advantages that can be extracted using so called VDC- or BIM tools. Some of the scientific reports reviewed during this study on the other hand, highlights the importance of the infrastructure and earthworks stages as a part of the entire construction process. Many also believe that the infrastructure and earthworks stage play a key role in whether a construction project achieve success or not. With that in mind, the authors feel that 3D-models for infrastructure and earthworks, have not yet been explored to the extent that feels necessary, meaning that the advantages and the various obstacles that stand in the way of a successful implementation process needs to be investigated. There is no doubt that building construction has come further in a digital development aspect of visualizing projects in 3D, compared to infrastructure and earthworks.

    In this study the authors have highlighted the benefits that can be gained by visualizing infrastructure and earthworks projects in 3D. The study also shows evidence of why the application of such should take place and what companies should be considering when implementing 3D visualization into such projects. The purpose of the study is therefore to investigate how the company researched by the authors can integrate 3D models into their infrastructure and earthworks projects. This in addition to identifying the requirements that the employees have on a 3D model to facilitate development of a tool that fulfils these requirements and is usable in production. In addition, the conditions and requirements that play a main role in infrastructure and earthworks projects have been investigated to identify the most suitable conditions to allow the model to work in the most efficient way as possible.

    The study is conducted with a qualitative method including an examination of existing literature that highlights the problem areas identified by the authors. In addition, semi structured interviews are carried out with employees from the work-site leadership and the skilled workers at the company Veidekke Entreprenad AB. This to identify the current problem areas in the production of infrastructure and earthworks projects and to examine employees’ view about how 3D models would impact on their everyday work. A clear overall conclusion is that 3D-models are truly needed in infrastructure and earthworks projects out in production. A lot of factors indicate that the tool would, among other things, contribute to an increased understanding of the scope of projects and thus contribute to an improved communication and production process leading. Such a tool can according to this study, also minimize problem areas regarding technical solutions, contribute to a better planning, and by digitizing processes, increase job satisfaction for the site team.

    Pressade byggtider i byggbranschen: En studie om tidspress på platsledningen med arbetsledaren i fokus.2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report contains a study of how pressured construction times affects the foreman in construction. Pressured construction times are becoming increasingly popular in today´s construction industry and is a subject that can be perceived differently from case to case.

    This report aims to get a better clarity on what pressured building times means and how it affects the foreman. Three main questions were made before the case study began: What does pressure construction times mean? How does the foreman perceive his workload in construction projects during pressure? What work tasks the foreman has that is mainly affected by pressured construction times.

    To ensure that the right purpose of the report could be fulfilled a choice of method was done before the essay could start. The method used in this case was a qualitative method based on a theoretical framework followed up by nine interviews with foreman’s and site managers at three different construction sites.

    The most interesting conclusion that were made during this report was that work experience wasn’t something that made the workload lighter for the foreman. The workload is instead increasing over the year as the experience grows wider due to the higher expectations on the individual.

    Do firm-level barriers to construction product innovation adoption vary according to position in the supply chain?2019In: Construction Innovation, ISSN 1471-4175, E-ISSN 1477-0857, Vol. 19, no 2, p. 212-235Article in journal (Refereed)
    Abstract [en]

    Purpose

    The purpose of this study is to examine product innovation as a means of addressing infrastructure shortages in developed economies and to improve the sustainability of infrastructure. The obstacles to product innovation in the road industry are compared between different types of participants in the supply chain to provide guidelines for interventions to improve innovation rates.

    Design/methodology/approach

    This exploratory study uses descriptive data from a large scale survey of the Australian road industry. The three top-rated product innovation obstacles for the following four types of participants are examined: contractors, consultants, suppliers and clients.

    Findings

    The four groups were found to disagree about the relative importance of the obstacles. Contractors and suppliers ranked “restrictive price-only tender assessment” used by clients as their number one obstacle, while consultants thought there was too much emphasis by the clients on direct costs compared with whole-of-life costs. On the other hand, clients felt suppliers do not do enough thorough testing prior to proposing a new product and disagreed with suppliers about who should carry the risk of new product failure.

    Research limitations/implications

    The conceptual framework was found to yield novel insights with significant policy implications. The construction-specific contextual determinants that were integrated by the authors into a broad innovation diffusion process proved useful in categorising road product innovation obstacles across the four surveyed supply chain groups – without overlap or omission. The new framework also proved useful in ordering the key obstacles across groups for interpretation and discussion. In disaggregating product obstacles according to groups, these contextual determinants were proven to be mutually exclusive and to represent important focal points in promoting the uptake of product innovation in construction. Although the current study has usefully provided quantitative data concerning construction innovation obstacles, there are limitations due to its reliance on descriptive statistics. Future work by the authors is proposed to analyse the relationships between innovation obstacles and supply chain partners using inferential statistics to further develop and validate these early findings. The current study is an interim step in this work and an important contribution in identifying and addressing firm-level barriers seen to be constraining construction product innovation.

    Practical implications

    Results suggest there is a need for government clients to carefully consider the differing perspectives across the supply chain when developing strategies to encourage the adoption of mutually-beneficial innovative products on their construction projects. Inclusive focus groups examining the drivers, configuration and benefits of collaborative procurement systems are recommended to reduce innovation obstacles.

    Social implications

    Society relies on urban infrastructure for daily living and the current study contributes to stretching infrastructure investment dollars and reducing the environmental impact of infrastructure provision.

    Originality/value

    No previous study has compared the perception of product innovation obstacles across different road industry supply chain partners. This is a significant gap, as differences in opinions across the supply chain need to be understood to develop the shared expectations and the improved relationships required to improve product innovation rates. Product innovation is important because it has been shown to improve efficiency (potentially addressing the road investment gap) and reduce deleterious environmental impacts.

    Construction Innovation: Addressing the Project–Product Gap in the Swedish Construction Sector2013In: International Journal of Innovation Science, ISSN 1757-2223, E-ISSN 1757-2231, Vol. 5, no 1, p. 1-9Article in journal (Refereed)
    Abstract [en]

    The construction sector is often accused of being inefficient, conservative and noninnovative, although some commentators have suggested that the construction sector is not backward, it is merely different to other industries. One of these differences is the uniqueness of construction projects, which are determined by the characteristics of the site, interaction of project participants (also partly site specific) and the relationship between contractors and building product producers (which changes from one project to another). These factors are known to colour construction innovation. Previous research into the Swedish construction sector has identified a significant gap between the building product producers who are 'product focused' and the contractors who are 'project focused', with concerns expressed about effectiveness of communication between two. The findings of previous research imply, both implicitly and explicitly, that this gap may be hindering innovation within the construction sector. This appears to have implications for those concerned with construction, the building users and society as a whole. In this paper the authors provide an extensive review of the literature and research findings from which a number of unique insights are offered. The reasons for the gap between producers and contractors are discussed and a number of innovative measures are proposed that may help to bridge the gap, and hence improve innovation systems. The paper concludes with some practical findings for producers and contractors as well as some thoughts on where future research should be targeted.

    Developing a Design Process for Mobile Applications for Logistics in the Construction Industry2015In: Proceedings of the 3rd International Conference on Innovation and Entrepreneurship (ICIE-2015) / [ed] Ramjugernath, D., Reading: ACAD Conferences Ltd , 2015, p. 164-170Conference paper (Refereed)
    Abstract [en]

    Construction material suppliers have access to various types of information, such as construction data, price, production planning and logistics data. This information could be of great use for the different roles involved in a construction project if the right information is presented to the right role and through a user inter-face designed for best under standing by each role. This situation is not unique for the construction industry, but the specific context with temporary organizations (construction projects) that have to communicate with permanent organizations (construction material suppliers) combined with the fact that, at least, six roles (categories) of employees are involved in a construction project places challenges on the industry to achieve effectiveness. In this paper a process to develop a information interface between construction projects and construction material producers will be presented. Using an interventionist research approach with interaction designers involved, the process aim to guide the development of an application for exchange of information between the actors in the construction projects.

    Energieffektivisering av Villor: Finns möjligheten till Passivhusstandard för befintliga bostäder2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The climate change the earth today has to face is no longer a global problem when every individual has a responsibility to act. The residents in Sweden have no understanding how their energy consumption affects the environment, nor what measures can be taken to reduce the energy consumption.The use of the energy in new Buildings is considerably lower than in the older ones as conditions have improved and the requirements have been more stringent. As most of the buildings in the future have already been constructed it´s important to take every opportunity for energy efficiency and rebuilding of available buildings will become a significant act. Reconstruction of a building contributes generally to both a reduced individual and a reduced total energy use, while new constructions only keep a low individual energy use but a increase the total energy use. For this reason we present the opportunities for reconstruction, mainly to reach the standards for a passive house.

    Stomstabilisering hos prefabricerade betongkonstruktioner i 3D-beräkningsprogram2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis has been executed in cooperation with Abetong which is a leading company in the prefabrication of concrete structures. For a prefabricated concrete building the design engineer must take into consideration the connections between the concrete elements in order to make sure that the building will possess a sufficient structural stability. Therefore the structural engineer might have to re-calculate the original structure that often has been designed as an on site-built building. The purpose of this thesis is to examine the forces between elements related to different models to see if the structural engineer has to make a re-design. To get results for this study we have used FEM-design 3D Structure. The results of forces from the program were compared with Abetongs standard forces of point connections and recess lists and showed that the structural engineer can use the original calculation up to around five stories when a prefabricated shall be erected.

    Abstract [en]

    To achieve structural integrity in precast concrete systems, connections between elements must be capable to transfer both vertical and horizontal loads which puts high demands on single ties.

    Hollow-core slabs are often used to stabilize the structural system which puts high demands on the connections between the slab and the buildings stabilizing units. Because of this, the connections need to withstand high tensile and shear forces.

    The purpose of this report is to investigate the tensile capacity of tie-connections used between hollow-core slabs that are parallel with e.g. stabilizing walls and compare with current design methods. Current design methods suggest that tensile failure will occur in the roof and bottom of the cores which provides low design capacities. Two connections are investigated through full scale pull-out tests where the results are compared with the design methods.

    The results from testing the tensile capacity show that the failure module occurred as suggested. However, the tests show significantly higher capacity than proposed by the design methods.

    Eurocodes Design assisted by testing are applied to the test result and a new design method is proposed. Both provides design values that are approximately twice as large as the values suggested in previous design methods.

    3D-Detaljplaner: En kartläggning kring 3D-detaljplaner utifrån ett företags-, kommuns- samt civilt perspektiv.2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The zoning plan is considered difficult to interpret and there is a great need to digitize it. Previous studies highlight that BIM and GIS can be applied in the zoning plan, this means that the zoning plan can provide new functions and improve visualization. An implementation can create opportunities for several improvements, such as the zoning plan process, building permit management and communication between actors can be improved.

    The purpose of this study is to map out what problems the relevant users have with today's zoning plan. Also, how a 3D-zoning plan should be applied, and what it can contain further for information and new functions.

    The study is conducted with a qualitative method. By studying literary studies, what possibilities a 3D-zoning plan can offer is examined. In the study, semi-structured interviews are conducted with municipalities, construction companies, architects and private individuals to understand what needs to be developed, and how it should be conducted.

    Analyzing and discussing results in what opportunities a 3D-zoning plan has for an implementation and what it takes to make it a reality.

    An overall conclusion is that a 3D-zoning plan is difficult to implement today. During the study several factors contributing to this conclusion. Common standards between companies, municipalities and architects must be determined. The authors' conclusion is that the zoning plan should not be visualized, instead a new visualization system should be created to support the zoning plan.

    Hantering av logistik på svåråtkomliga platser: En studie om materialhantering och informationsflöde vid byggprojekt i innerstadsmiljö2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    One of the essential factors for a functional and hassle free construction project is well planned and organized logistics. At urban construction sites that are characterized by limited space and constant challenges given by the conditions of the location, it becomes even more relevant to plan meticulously. It is a fact that the construction business has its flaws when it comes to manage the different types of wastes that are within, and constantly working with logistics is the only way to effectively use the resources, both economically and in terms of time.

    This paper will from this background enlighten the logistical problems that emerge because of the conditions in the city, identify the most critical, and observe how they are taken care of. From our observations we noticed that lack of space and a poor communication between operators in and around the project, often is the common denominator when problems surface and are especially important to manage in inner-city projects. The issues seem to be connected to a very complex logistic network, where it’s hard to coordinate the operators further down in line. This also differs a lot depending on the size of the project, and the smaller sites often have less logistic awareness.

    The structure of emergent prefabricated housing industries: a comparative case study of Australia and Sweden2019In: Construction Management and Economics, ISSN 0144-6193, E-ISSN 1466-433XArticle in journal (Refereed)
    Abstract [en]

    Prefabricated housing is a disruptive innovation struggling to take hold in a traditional complex product system (CoPS). It is quicker to produce and has improved environmental performance compared to traditional housing. CoPS have more dense and complex network connections than commodity industries, making disruptive innovation more difficult. Effective relational capabilities can achieve the coordination necessary to address this challenge. The prefabricated housing industry needs to develop a structure that drives these capabilities. Using a case study methodology, the structure of the industry is examined in two contrasting countries, namely Australia and Sweden, as they represent an early and late stage of industry emergence, respectively. A new framework is proposed for this purpose, enabling a repeatable, orderly and comprehensive disaggregation of industry structure to examine the latent drivers of relational capability. The main empirical contribution is to (1) describe an industry that is yet to be formally recognized by national statistical agencies and (2) show how the adoption of prefabricated housing can be accelerated. The study found that younger industries need a focused industry association with diverse membership to act as an effective system integrator. © 2019 The Author(s).

    Livscykelanalyser i byggbranschen: En kartläggning av den svenska entreprenörssektorn2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The knowledge in the industry varies and it is far from all that works actively and continuously with Life Cycle Assessment. Discussions on issues dealing in particular with standardization,implementation, resources, future scenarios and advocacy opportunities occur frequently, and in the form of different standpoints. A common methodology and standard is demanded by all respondents. It is considered as one of the major inhibitions, as well as knowledge and the lack of interest from clients when it comes to the demand and use of LCA. It will require education in the subject at all levels of the company that deals with the analysis. Adequate knowledge is a must to use the LCA tool optimally and will be required for it to be considered cost effective and worth investing in. Data tools are a prerequisite and requests have been made to develop simpler and more manageable programs. The clients play an important role in the initial stages when the requirements tend to follow throughout the project. The production phase will be more focused as industry reports highlights it. The future of LCA and its implementation is considered to be good.

    Kan korslaminerat trä effektivisera ett byggsystem: En jämförelse av flervåningshus i trä2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The construction of wooden multi-storey buildings creates issues with the acoustic environment. To meet Boverkets soundproofing requirements the solutions of today results in thick partition building components taking up potential floor space. Crosslaminatedtimber is a solid timber slab that can be manufactured in varying sizes and thicknesses. These boards can then be used as supporting elements in walls, ceilings and floors. This study investigates whether cross-laminated timber can be used to streamline the construction of multi-storey wooden buildings. In this comparative survey a reference building constructed by A-hus was used and current loads, sound insulation, use of floorspace and economy were analyzed. Four different alternative walls and one floor constructed with cross-laminated timber have been studied according to the above named criteria, and then compared with the reference building. The result indicates that a wall with 80 mm cross-laminated timber board has the load capacity required, improves sound insulation and saving 16 m2 of floorspace in the reference building valued to approximately 695,000 SEK in increased sales revenue. Using cross-laminated timber in the floor does not sufficient improve A-hus current construction system and should therefore not be interesting.

    Härdnings- och stämpningstider för prefabricerade murstensskift2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    According to good practice within the Swedish masonry industry brick beams needs to be underpinned during the 28 first days. Masonry craftsmen and construction engineers believe that the supports can be disassembled before this time has elapsed. This will facilitate subsequent entrepreneurs to begin their work earlier. Previous studies on this subject haven’t been done. Within this project tensile tests have been made in order to find out how the adhesion between brick and mortar develops over time, and how the temperature affects it. The aim has been to test if the adhesion is strong enough to remove the underpinning earlier than 28 days. Interviews with bricklayers and project managers have been done to get their point of view on the problem. The result of interviews showed that bricklayers removed the underpinning earlier than 14 days, the results of the traction tests did show that the underpinns can’t be removed after an exact number of days. What determines if the stamp can be picked up earlier is the size of the opening and the temperature it cures in.

    Arkitekten och brukarmedverkan2008Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Working conditions and regulations encourage everyone to participate actively in shaping the surrounding environment in order to increase the social durability. End-users’ participation during the construction process will contribute to building better products that fulfil their needs and requirements. Meanwhile the real estate administrators will achieve a long term economic success if all renters are satisfied and prolonged their contracts. Contrary, for the individuals, both the social value and health aspects are possible to influence in shaping the living environment and working places. The aim of this study is to analyse how architects can transform and manage end-users’ demands, needs and requirements during the construction process where the construction documentation are formulated and followed-up. Emphasis will also be on how the architects’ education supports the profession’s role as facilitators in the process of involving end-users. Two case studies had been performed in order to highlight the architects’ role and involvement of end-user in the process. In order to gain an understanding on how the architect students and the professional architects view the research problems, questionnaires were used. A big asset in the construction industry is the individual knowledge gained and the mutual competence that are acquired during the construction project. For that knowledge to be useful, it requires the right working conditions, suitable organisation and above all time. Time and dialogue combined with the right tools will depict the right picture of what is to be built. Clients that work with the developed forms of cooperation provide resources at the early stage of the project which form a good condition for construction process. Both the students and the professional architects consider that it is necessary to be more participative as a society builder in the development of a durable society. A problem in the professional role is the experience feedback from end-users which results in knowledge gap about the end-users needs. A stronger cooperation between the architect and the engineer during the education period will lead to a better teamwork in the construction process. The development of a durable society requires a durable process.

    Potentiella armeringsfel inom byggproduktionen: En generell studie2014Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Reinforcement is of great importance to fulfill the dimensioned strength of a concrete construction. This requires that the work needs to be carried out with adequate results that neither endangers the workers or the safety of the construction. Progressive development of the planning phase, construction documents, and construction methods is in constant need since the technology constantly evolves.

    In order for contractors to be able to get acceptances from their quotations requires that they have to increase their working pace in order to be able to leave a quotation with a lower price than the competition.

    Due to the increasing pace the different parts involved in the construction process is subjected to time pressure. The design stage, construction documents, work preparation and the execution are all affected when everything has to be finished quickly. To avoid problems, it is required that all parts are able to deliver good quality solutions and results under the influences of time pressure, which is not always easy. It happens that problems and mistakes occur, however they are usually not extensive, but in some cases the errors can lead to severe consequences such as structural collapse.

    This thesis has been written with the purpose to discern and enlighten the most common errors during the reinforcement process, especially orientated towards reinforcing drawings. Literature studies with elucidation on old known problems and errors have been investigated and thereafter compared with present issues. Data collection was conducted through interviews and a survey distribution to personnel with relevant experience.

    The results of the interviews and surveys revealed that several significant errors have arisen, errors that previously weren’t taken into consideration. The computerized society has led to the construction process, in some cases, becomes faster than the planning phases. Some parts in the construction process no longer have the time to do extensive and thorough planning as they used to be able to. To prevent these problems, extensive quality checks, but also competence- and execution training for involved personnel is needed.

    By knowing the most common errors during reinforcement work more focus can be given to these parts in order to increase the probabilities of the work being executed correctly.

    Vägen till produktionsanpassade arbetsinstruktioner2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis was to investigate the need of working instructions in Derome Träteknik ́s industrial house-building factories. Furthermore we wanted to determine an appropriate way for developing working instructions adapted to the conditions in a certain production environment. In the construction industry today prefabricated building elements are frequently used. With this come repetitive work tasks that need to be carefully planned. In the planning process industry regulations, laws, requirements from suppliers and preferences from different actors in the certain company have to be included. Only then the positive effects of industrial building will be fully achieved. In our thesis we took these aspects into account by systematic observations, meetings with the company management and by a dialog with the suppliers. We also followed three working processes in detail and developed working instructions for one of them. The outcome of the report was that the most imported steps towards developing working instructions were identified. These were organized chronologically in a list.

    Förnödenhetshantering på byggarbetsplats: Effektiviseringspotential med leverantörsbaserade logistiktjänster2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The challenge of managing necessities is something that is well known in the construction industry. This has given rise to suppliers inventing different logistical services that will improve the efficiency and working environment in the construction process. The earlier research shows problems concerning purchasing, delivery, usage and replenishment regarding necessity management.

    The purpose of this study is to show how supplier-based logistic services can contribute to increased efficiency and in addition to this improve the working environment in the construction process.

    The author has chosen to carry out the study through qualitative methodology. The literature used has been necessary in order to identify the different problem categories. In addition, interviews have been held with suppliers and semi-structured interviews at site visits to PH Bygg AB and YLAB were conducted to investigate the various problem areas without logistics services and the effects of using logistics services.

    The analysis and discussion of the results has been used to investigate and confirm the efficiency opportunities that exist when using supplier-based logistics services. The conclusion of the study is that the use of supplier-based services gives rise to a more efficient construction process. This is possible because different processes are either eliminated or transferred to suppliers, and this leads to shorter processes for the construction contractor. In addition, this has given rise to the fact that the respondents who use these services feel that the working environment has improved.

    Abstract [en]

    Lime Hempcrete consists of lime, water and hemp and creates an insulating, sound-absorbing, lightweight and environmentally friendly material that can be used in wall, roof and floor structures (Bevan & Woolley 2008). This construction method is not yet developed in Sweden as there has been a ban on the cultivation of the hemp plant. This ban on the cultivation of hemp was removed in 2003, when the material got a boost. You can use it in many different ways and not just in the construction industry (Ahlsten, 2010).

    In this study we have investigated the possibility to produce prefabricated wall elements of LHC. We have also studied its mechanical properties and dehydration time. Different types of mixes were made to find out which type of blend that worked best and had good workability properties. Four different types of wall elements were made to see how they react when they are handled and lifted and to show how you can connect the wall elements to each other and how you can connect them in corners.

    Tilläggsprogram för BIM förenklar byggprojekt: En undersökning om produktspecifika tilläggsprogram med utgångspunkt i projekteringsfasen2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    You can describe BIM, Building Information Modeling, concisely as a model where all the information for a building project´s design, construction and management can be organised.  With BIM, you can download add-ons that can simplify the work design and for following work in production for example. With these add-ons, the suppliers’ building products can be used when modelling the building projects instead of the standard products that are available in the software. The product-specific add-on tools are quite recent and have not been introduced to the construction industry as such.

    The aim of this report is to present an overview of whether BIM simplifies construction projects, and if so, how?  The goal is to give companies an understanding of what BIM is and how it can be used in a project through the design phase. To achieve the purpose and aim of this report, a qualitative study has been conducted. The materials for this study were collected through literature studies of substance relevant books, through relevant research reports and industry organization homepages on the internet.  Facts were also collected through interviews with industry experienced personnel who are familiar with both software and add-ons.

    The result of our case study, which was to examine the application of an add-on in a construction project, the construction project of "Triangeln" in Malmö, was compared with the theories that we found through the literature studies.  In this report, the programme´s functions have been investigated and presented. A conclusion is that, with the product specific add-ons, the design phase will become more detailed and advanced but will also contribute to simplifications, especially in the production phase. In the design phase with BIM and the add-ons, it can take a little longer to perform than usual because of the degree of details and project design. However, this time is not wasted as time will be saved in the production phase as a result of the BIM and add-ons in the design phase. Furthermore, by allowing the actors involved to participate earlier in a construction project, the impact on the building's design is affected in its favour, resulting in a simplification of the work in the design phase. The add-ons also make it easier for customers to use the company's products in the building design, by letting companies develop and have their own product specific add-on. This will gives the supplier an advantage in both sales and in the marketing of the products. By doing this, the supplier companies also guides users towards utilising simpler working methods which will benefit everyone.

    Cooperation in the Swedish construction industry is largely due to the project in question will be successful or not. We have in this thesis study the critical factors of cooperation between the main and sub-contractor to work throughout the project. We conducted the study through both interviews and a survey to get as wide basis as possible and by that represent the whole industry. We chose to highlight the bits that the various participants consider to be of greatest importance to their work, to work as good as possible. The result of our study shows that the problem of cooperation is perceived differently depending on where in the process the person is sitting. And there is much that can be improved to increase the efficiency of the entire process by improving cooperation. We chose to limit ourselves to see the collaboration from the design stage to start until the building is completed. We have also chosen to limit ourselves to ensure the Swedish construction industry.Cooperation in the Swedish construction industry is largely due to the project in question will be successful or not.

    Innovation brokers in the Swedish construction sectorManuscript (preprint) (Other academic)
    Abstract [en]

    As demand on the construction sector to improve has grown in many countries an increasing understanding of the complexity of the national innovation system has developed. in other industrial sectors, with similar complexity, the concept and the importance of innovation brokers has been identified. This concept is examined here in the context of the Swedish construction sector. A number of organisational types, acting as innovation brokers, have been identified. There are no organisations acting as innovation brokers solemnly and their level of independency can to some extent be questioned. This may not be a problem as such; because of the construction innovation system in Sweden varies from the innovation systems from where the concept of innovation brokers has been identified.

    Innovation Diffusion in the Construction Sector2006Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Innovation and development are the backbone of a thriving market economy. It is through innovations of various kinds that nations, industries and companies compete. Many actions in areas internationally and nationally will affect the construction sector. Research into construction innovation has attracted increasing interest. There have been studies ranging from how national research policies support construction innovations to how projects should be organised. One general conclusion is that the level of innovation needs to be improved. There is a need to assess the potential barriers and enablers to achieving a better diffusion of innovations in construction. The overall aim of the research is to increase knowledge of the factors creating successful development, implementation and diffusion of innovations in the construction sector. More specifically, the research aims to understand where the usefulness and weaknesses exist in applying established innovation theory, particularly in regard to diffusion, within the Swedish construction context with the further aim of identifying a suitable basis for creating a shared understanding among stakeholders of the innovation process at work.

    A conceptual model for improving the existing situation was developed using contextualised innovation and diffusion theories. The model was tested using the findings in several supporting papers. It was found that actions in line with the conceptual model would enhance the probability of successful diffusion. The research has also investigated national policies, innovation brokerage and (research and) development projects in Sweden and found systemic weakness in the innovation process. The research has also found that tools of analysis not normally associated with the research problem in the construction domain can be used to provide improved insights to policy makers, innovation brokers and development managers. Significant in this regard is the criticality of communication vertically within the supply chain and laterally amongst suppliers with respect to specific innovations, such that diffusion becomes a normal and, therefore, integral feature of construction activity. The tools of analysis identified and adopted in the research can be used directly by policy makers, innovation brokers and development managers to lead to a shared understanding of barriers and enablers to innovation and a basis for continual improvement. In this connection, causal loop diagrams can aid in assessing the type of organisations needed in communication. Shortcomings in communication can, to a certain extent, also be mitigated by innovation brokers.

    Innovation in the Construction Process; a comparison with Complex Product SystemsManuscript (preprint) (Other academic)
    Abstract [en]

    Innovations in construction materials and components are made without being integrated with other materials and components. It is not even enough with innovations only in construction materials and components. This paper is mainly a literature study of research regarding Complex Product Systems (CoPS) and the construction process. The construction process can be compared with theories concerning another context, as in the case of theories of CoPS. According to theory, one problem in a construction process is that solving single issues is not adequate as the required result is often influenced by other issues, confounding the expected outcome. CoPS focuses on system design, knowledge transfer, cross co-operation interactions and communication, and skills and knowledge. It is necessary that these focus work well to achieve an innovation process. Using traditional forms of cooperation, these areas often pose problems in the construction process. The forms of co-operation, which have greater potential than others, are those that do not separate design from production.

    Innovation in the Construction Process: A Theoretical Framework2002Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The demands on the construction industry can be met either by fulfilling them by applying existing knowledge and solutions or by creating something new. Trying to meet demands with existing knowledge and solutions is only possible to a certain point, beyond which it is necessary to create something new.

    This thesis aims to create a theoretical framework for new forms of co-operation that encourage innovative procedures. The theoretical framework is based on innovation theories.

    Findings suggest that motivation to innovate is important. It is mainly the client who can provide the incentives for innovation, while it is mainly a malfunctioning process that breaks them down. The process is very much the result of the forms of co-operation used. In the comparison between the construction process and the innovation process eight aspects are found, which are directly influenced by how the co-operation forms are function, namely, allowing the actors to be involved during an extended period of every project, communication, contractual incentives to encourage innovation, early involvement of the different parties, learning, relationship and co-operation with other parties, risk and reward, and support for the idea of longer relationships between the actors.

    Modelling the causes and effects of problems in the construction processManuscript (preprint) (Other academic)
    Abstract [en]

    The construction process is faced with many challenges, not least dealing with concerns over an adversarial culture, weak suppliers integration and variable quality. With its different levels and numerous participants, the process can be a complex affair. There is a need to understand how the different elements of the process relate to, and effect, each other. The paper presents an analysis of the relationships between certain of these elements, by treating the construction process in a system' context. The particular use of casual loop diagrams to help improve understanding of the interdependences between elements that are considered to the problematic is explored. These diagrams can be used to identify connections of importance when seeking solutions and examples of their use are presented. They show the relationships between problems and those factors that may reinforce or balance one another. The approach advocated in this paper provides tentative steps towards unravelling some of the complexity that obscure the root cause of problems inherent in the process.

    The Construction Process; a Systems ApproachManuscript (preprint) (Other academic)
    Abstract [en]

    The construction process is believed to have problems. The causes suspected and their solutions have been put forward, but the problems in the construction process have not disappeared. The primary aim of this article is to show that many of the problems perceived are interlinked in a system and that this is one of the reasons that the solutions have not had the expected impact. A systems approach, with reinforcing and balancing causal loop diagrams, has been used to show this. A secondary aim is to give some recommendations for the improvement of the construction process. The article first investigates how to fulfil the goals of a project and solve the problems perceived of the construction process. The main findings are that the systems approach gives a useful understanding of the interconnections between some of the perceived problems and that in some cases it is not enough to change only the most obvious cause of the problem. The causal loop diagrams clearly show that the reinforcing loops are balanced by balancing loops. These are good as they will hinder negative reinforcing loops from becoming vicious, but bad as they may hinder a positive development of the reinforcing loops.

    Abstract [en]

    Although construction is considered to be slow in adopting new technology and new processes, innovation, research and development are performed routinely. Nonetheless, knowledge about what affects the diffusion of research results - in the context of innovations - is incomplete, limiting the effectiveness of procedures designed to evaluate project proposals. The aim is to examine the factors that can influence the diffusion of results, in this case from externally funded construction innovation projects. A Fisher's exact test is performed on six concepts derived from general innovation theory which are tested on 20 development projects. The test is used to establish the significance of the six concepts and their applicability to construction-related innovation. The results reveal support for all six concepts, although only four of them attract a high level of significance. External lateral and vertical communication and external integration during the development phase are shown to increase the chances of successful diffusion and should therefore be assessed in project proposals.

    The construction sector tries to take the lead – A sector lead approach to construction process improvement2005In: Proceedings of the 2005 International Conference on Construction and Real Estate Management : Challenge of innovation in construction and real estate / [ed] Wang Yaowu & Shen Qiping, Beijing: China Architecture & Building Press , 2005, p. 274-277Conference paper (Refereed)
    Abstract [en]

    In many reports the improvements of the actors in the construction sector have been requested. One explicit factor that has been called for is an increase in cooperation and communication between the different actors. The Swedish construction sector in general has not been swift in accepting new process improvements as they have been put forward by academics or government. There are many possible explanations, among them are that the solutions have been too much of 'desk products', not suitable for direct application into the construction sector and its firms. In the southern region of Sweden a sector initiated and lead initiative with an aim of developing the construction and the real estate management process, increase the profitability across the supply-chain, increase the human value among the actors of the construction process, and increase the image of construction, has been carried out. The forum resulted in increase of knowledge of the construction industry and effect of different actors on it for those who participated. On a more general level a program with the aim of increasing the efficiency and improving the image of the construction industry was developed. This paper discusses the approach as such; advantages and disadvantages as well as lessons learned. It also reports on the outcome of the initiative.

    Institutional reasons for not implementing PPPs in the transport sector2012In: COST Action TU1001: Public Private Partnerships in Transport Trends & Theory: 2011 Discussion Papers / [ed] Athena Roumboutsos & Nunzia Carbonara, Bari: Favia , 2012, p. 108-121Chapter in book (Other academic)
    Abstract [en]

    Purpose – Italian implementation of PPP has its own features which distinguish it from other models adopted in Europe and in the world. International literature lacks of contributions about the Italian case, while the analyses on this issue in the national literature are not systemic. To fill this gap we aim at characterizing the main features of Italian PPPs, in comparison to the features of such partnerships in Europe and in the world.

    Design/methodology/approach – In order to describe the PPP implementation, the paper proposes a theoretical framework describing PPP as it is conceived by international literature.

    Findings – A set of factors, like uncertainty on the rules, complex procedures and the lack of private competences  on PPP, hinder the involvement of private operators in PPPs. Consequently, PPP project financing structure is mainly based on public guarantees, even because of scarce utilization of capital markets for funding.

    Social implications – Practitioners and scholars can use this framework analysis in order to know strengths and weaknesses of PPP application in their socio-economic context.

    Originality/value – The proposed framework represents a useful tool for comparing the application of PPPs among different sectors and different countries. Furthermore, the theoretical framework can be considered a starting point of future research aiming at developing a tool for assessing the expected performance of PPP projects.

    Effects of a Lack of Support for Public Private Partnerships: The Swedish Case2010In: Proceedings of the 6th International Conference on Innovation in Architecture, Engineering & Construction (AEC) / [ed] Anumba, C.

    Abstract [en]

    Sweden is part of a small European minority in the perceived societal gain of PPP. After a pilot PPP project in late 1990’s no additional project has been started in Sweden. Although there is interest from both public infrastructure clients and construction companies the national government has very clearly stated that infrastructure projects should be procured in a traditional way where all funding should come from the national budget. The purpose of this paper is to discuss how a lack of support for governmental interests in PPP solutions affect the innovative climate of infrastructure investments. Broadly defined, PPP solutions are arrangements where the public sector together with a private partner engages in a long-term co-operation to solve a public need. The opponents in Sweden base their arguments on the viewpoint that it if the state cannot finance a well needed infrastructure project within the national budget there is no need for a private initiative since the state can borrow funds on better terms than a private actor. However, the proponents see PPP as way of not only financing well needed project but also as a way of improving the innovative climate of the infrastructure sector. In short, the opponents only see PPP as an alternative way of financing public projects while the proponents see PPP as a opportunity to improve performance of infrastructure facilities by long-term partnerships and incentives to adopt new and innovative solutions in construction and maintenance. The study presented here shows that the main effects of a lack of PPP solutions is the following: First, the time from an identified need until finished project becomes very long since each project needs to fit in the yearly national budget. Secondly, when national funds are insufficient, well needed infrastructure projects are delayed in the planning process often with no definite new time plan, and very rarely does the government borrow additional funds. Thirdly, there is a tendency to divide large infrastructure facilities in smaller entities in order to fit them in the national budget, which has the effect that the full benefits of the investment are delayed. Finally, and maybe most importantly, the Swedish government’s reluctance to adopt PPP solutions and to finance infrastructure projects in small entities, promotes traditional design and build contracts with very small incentives for adopting new innovative solutions to improve the construction process.

    Links between Successful Innovation Diffusion and Stakeholder Engagement2014In: Journal of Management in Engineering, ISSN 0742-597X, E-ISSN 1943-5479, Vol. 30, no 5, article id 04014018Article in journal (Refereed)
    Abstract [en]

    Stakeholders can positively assist or hinder attempts at innovation. Much depends on the nature of their engagement. The stakeholder engagement process can be complex and unpredictable, more so if no strategic plan is put in place or if no systematic thinking is invested in the innovation. Stakeholder engagement in the innovation process in general and innovation diffusion in particular is examined in the context of construction. From a theoretical perspective, analysis of the effect of stakeholders could be expected to help in refining the innovation process so that it produces decisions and outcomes more likely to lead to successful innovation and diffusion. To cover diverse applications from product development to the drafting and implementation of national standards, 19 innovation projects were studied. Through a statistical analysis of stakeholder involvement, based on a Fisher's exact test, it was concluded that a structured process of engagement has to be an integral part of the innovation process. Accordingly, an explicit plan for communication and engagement with identified key stakeholders is necessary ex ante as a condition for successful innovation and diffusion. © 2014 American Society of Civil Engineers.

    Public Procurement of Industrially Produced Housing2009In: Proceedings of 5th Nordic Conference on Construction Economics and Organisation, Vol. 1, 2009, p. 13-20Conference paper (Refereed)
    Abstract [en]

    Purpose

    The aim of the research was to investigate how a model for public procurement could be designed with the aim of including industrially produced housing in the procurement process in Sweden.

    Methodological approach

    The study was performed in two steps, an initial literature review and then a case study. The literature review aimed at creating an understanding of how this is done in other contexts and what the public procurement legislation allows. The case study investigated the current procurement process using an existing project between two companies, one public client and a contractor.

    Results

    Conclusions from case study are that co-operation in an early stage is desirable as well as involving the contractor in an early stage. In the process every involved should get the opportunity to use their knowledge in the process and form the project. The criteria for evaluation is important as well as the objectives for the project. To use an industrial produced housing also demands special attention to the regulation of secrecy. An important conclusion is that it should be possible, within the existing regulatory context, to procure industrial produced housing. The adoption of competitive dialogue, though, would probably increase the possibility of it to happen regularly.

    Status

    The paper is based on research that is finished.

    Contribution

    The work helps to identify the problems and possibilities of public clients procuring industrially produced housing. It reveals that the main obstacles as such is not the legislation, but at the same time it could probably made easier by the adoption of competitive dialogue into the Swedish procurement legislation.

    Identifying bottlenecks in the photovoltaic systems innovation ecosystem – an initial study2018Conference paper (Refereed)
    Abstract [en]

    Solar energy is likely to play a major role in future renewable energy systems. One important part in that is the integration of photovoltaic (PV) systems into the built environment. Earlier studies show that the institutional framework plays a major role for achieving a broad implementation of PV systems. It has however also shown that the value network of PV systems needs to be understood and developed further. In that respect, earlier research on innovation diffusion into the built environment shows the necessity of involving and understanding key stakeholders. Stakeholder analysis may help in identifying key stakeholders but fail in assessing the stakeholders’ role in the value network as it does not, for example, take into account the relational effects. Innovation Eco Systems is an approach that has the potential to do this as it addresses the alignment structure of the partners needed for the value proposition to occur. The aim with this initial study is to address the use of innovation ecosystem as a way of assessing implementation of PV systems in the built environment. Two structured workshops with two key stakeholder categories, Clients and Suppliers, were held to identify the main barriers for a broader implementation of PV systems into the built environment in Sweden. The main results show that the earlier studies were right in that the institutional framework is a major factor, but also that the value network is important and that the problems in the value network is perceived somewhat different between the two categories. This suggests that it will be necessary to address the value network from the perspective of the actors by applying an innovation ecosystem analysis. It also helped in identifying other important stakeholders in the value network that will be needed to include in the future studies. To summarize, the findings of this initial study suggest that innovation ecosystem will address a more comprehensive picture on the implementation of PV systems in the built environment. However, to be able to identify bottlenecks and subsequent solutions to these bottlenecks further studies of the complete innovation ecosystem, with its stakeholders, is necessary. The ongoing project is currently carrying out these studies in a Swedish context.
