    Insourcad polsk arbetskraft i svensk byggindustri: En studie utifrån NCCs arbetslednings perspektiv2018Independent thesis Basic level (university diploma), 12 hpOppgave
    Abstract [en]

    The need for labor in the construction sector is today greater than the supply. As a result, several companies use foreign labor, which constitutes challenges. Previous studies highlight that problems can arise mainly in the categories of cultural differences, communication, security, quality and time.

    The purpose of this study is to investigate issues of foreign labor from the perspective of managers. Furthermore, the study aims to highlight positive effects with insourcing, a difference to previous research where the workforce has been external.

    The study is conducted through qualitative methodology where review of existing literature has highlighted apparent issues to handle. In addition, semistructured interviews where conducted with the case company management team to investigate experienced issues as well as the impact of the insourcing strategy. The analysis and discussion of the interviews results in a list of improvement suggestions for companies using foreign labor. A general conclusion is that insourcing is beneficial to construction companies using foreign labor, as it provides continuity and improved opportunity for development and guidance. Furthermore, the education and development of the workers is easier to follow up.

    A taxonomy of planning and scheduling methods to support their more efficient use in construction project management2016Inngår i: Journal of Engineering, Design and Technology, ISSN 1726-0531, E-ISSN 1758-8901, Vol. 14, nr 3, s. 580-601Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: The implementation and control processes of project planning and scheduling involve a wide range of methods and tools. Despite the development and modification and integration of the project management theory with newer scheduling approaches in particular, practitioners’ views on the efficiency and effectiveness of these methods and tools differ. This situation can be attributed in part to a lack of understanding of the most appropriate basis for implementing these methods and tools. This study, therefore, aims to overcome this deficiency by conceptualizing and adopting a taxonomy of planning and scheduling methods.

    Design/methodology/approach: The study is based on a review and discourse analysis of the literature covering a large number of theoretical and empirical studies. The underlying theories of various planning and scheduling methods were analyzed with respect to the taxonomy criteria adopted in the study.

    Findings: Using the taxonomy, the key characteristics of planning and scheduling methods considered in this study were identified and interpreted. These included concepts and theories; key features; suitability and usability; and benefits and limitations. Overall, the findings suggest that project managers should consider taxonomy as a support tool for selecting and prioritizing the most appropriate method or combination of methods for managing their projects. Recommendations include the need for more advanced or multi-dimensional taxonomies to cope with the diversity of project type and size.

    Originality/value: The results of the study allow project managers to improve their current practices by utilizing taxonomy when considering the implementation of planning and scheduling methods. Moreover, taxonomy can be considered as a tool to promote learning on the part of those less experienced in planning and scheduling. Taxonomy can be considered as an initial platform for further research in this area. © 2016, © Emerald Group Publishing Limited.

    Rullarmering: Att adoptera en armeringsmetod2015Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Rebar carpet is an innovation that favors the working environment of the rebar workers and saves time. Reinforcement workers today are a vulnerable group. Heavy lifts and backbreaking postures are a part of their everyday work. It is already established that work with rebar carpets is both time-saving, economically beneficial and from a working environment point of view better than traditional reinforcement work. Despite all benefits it is used in rather few projects today.

    The purpose of this study is to identify how the construction industry embraces new innovations related to in situ concrete with post-tensioned reinforcement. The goals are to find out how designers, contractors and manufacturers are working to adopt rebar carpets in the construction process and to shed light on, factors affecting the adoption.

    The study is based on semi-structured interviews with designers, contractors and a representative of a rebar manufacturing company.

    Designers and contractors have not, generally speaking, been actively working to adopt rebar carpet. The governing factors for the use of rebar carpets is the designers and contractors knowledge and previous experience of rebar carpet. The contractors who have previous experience of rebar carpet can imagine using rebar carpet again and contractors with no previous experience believe that they need more knowledge of rebar carpet before they dare to try. Design engineers who have designed for rebar carpet before has it in mind when they design other projects. Designers who have no previous experience of rebar carpet demand more knowledge about how they can facilitate the use of rebar carpet.

    Innovation Barriers and Enablers that Affect Productivity in Uganda Building Industry2007Inngår i: Journal of Construction in Developing Countries, ISSN 1823-6499, E-ISSN 2180-4222, Vol. 12, nr 1, s. 59-75Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The construction industry has of recent been blamed for lack of innovation. Lack of innovation in the industry is believed to be responsible for the decreasing or stagnant levels of productivity in comparison with other industries. This paper reviews the major barriers and enables to innovation in general. Propositions were made about the factors that affect innovation in the construction industry which were then formulated into a questionnaire. A survey was made on building contractors in Uganda, a developing country, targeting those with financial strength, large in size, and with high capacity to carry out big projects. The identified factors were then ranked and correlated. The level of training in science, engineering and technical education, and the level of research and development at the industry level are looked at as the greatest innovation enablers in building that will drive forward labour productivity. The size of the domestic market and the level of security are the worst innovation barriers that lead to low productivity in the building industry in Uganda. Contractors, policy makers and the government should address the identified factors in order to improve productivity.

    Towards a Taxonomy of Planning and Scheduling Methods in the Context of Construction Management2013Inngår i: Proceedings from 7th Nordic Conference On Construction Economics And Organisation 2013: Green Urbanisation – Implications For Value Creation / [ed] Ole Jonny Klakegg, Kari Hovin Kjølle, Cecilie G. Mehaug, Nils O.E. Olsson, Asmamaw T. Shiferaw & Ruth Woods, Trondheim: Akademika forlag, 2013, s. 570-581Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Planning and scheduling are considered as one of the most difficult but most important processes from perspectives of project management. These processes involve implementation of a widerange of planning methods used by different organizations with various levels of planning knowledge. The planning methods for scheduling can be classified as traditional methods (e.g. line of balance, Gantt chart and critical path) and modern methods (e.g. last planner and critical chain). Over time these methods had advanced from paper based to computer based. However, some project planners still prefer using the traditional methods despite other new alternatives. Users of those methods have different perspectives about the efficiency and effectiveness of the different planning methods used to manage different projects. Evidences from the secondary data found from extensive literatures have been used to assess the planning and scheduling methods mentioned above. A taxonomy describing each of the method in terms of their theories, key features, application areas, benefits and limitations is presented. The preliminary outcome of this paper may provide a tool to aid organizations in selecting and prioritizing the most appropriate methods to be developed and implemented in planning and scheduling of their projects. It also initializes a theoretical base for more rapid taxonomy studies on the use of different planning and scheduling approaches. As an overall, the present paper reminds practitioners of common ground about its important insights on how such taxonomy studies have potential to make scope of those methods and tools clearer, especially when they compare among them within the same application contexts.

    En villaleverantörs möjlighet till etablering i Finland: analys av för- och nackdelar2015Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    The construction market has, as a result of the crisis in Europe been uncertain in recent years. During the year 2013, the construction will be stabilized, in particular Finland. The geographical proximity between Sweden and Finland and similarities in cultures and climates makes Finland a coveted market for many Swedish companies.

    Differences in national regulations and guidelines, which are produced by the authorities in different countries, are examples of barriers that may hamper the process, including for Swedish villa suppliers, to establish themselves on the Finnish market. It may be useful when facing a new export drive, to look up what similarities and differences there are between the countries building codes, to prevent mistakes and unnecessary costs to the project work.

    Abstract [en]

    In Sweden there are 299 000 working in the construction industry. The construction industry is one of the industries where most accidents occur every year. During the last ten years there have been 111 death accidents in the construction industry and 48 of them were falling accidents. That means, in average, one death accident every month.

    Falling accidents gives serious injuries to the persons who are affected by them. It is anticipated that this report will investigate the factors beyond the falling accidents and also to present proposals that can decrease the number of falling accidents in the future.

    To secure a healthy and safe construction site it is of great importance that both the employers and the employees cooperate towards the same goal. A good work environment will benefit both the employer, the project will be finished in time with a good profit margin, and the employees will be satisfied to everyday come to a secure construction site.

    The result of this report indicate that it’s very important to plan the work before executing it ,so that everyone involved knows what they are going to do. This, together with, better management from the company’s directors to the employees will reduce the risk for accidents to occur.

    BIM Adoption in University Teaching Programs: The Swedish Case2013Inngår i: Proceedings of CITA BIM Gathering Conference 14-15 November 2013 / [ed] Dr. Allan Hore, Barry McAuley, Dr. Roger West, Dublin: The Construction IT Alliance , 2013, s. 163-168Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Implementation of BIM in the construction industry relies on sufficient knowledge and skills about BIM in order to gain momentum and success. Thorough understanding of the possibilities as well as challenges related to the application of BIM constitutes essential drivers for the adoption of BIM among all the industry actors throughout the construction process. Thus, there is a need for supply of knowledge and skills about BIM and its implications on the organisation, communication, management, business models etc. in construction. Accordingly, universities play an important role as a knowledge and skills supplier that helps to provide the necessary conditions for the implementation of BIM in the construction industry. This study investigates how the curricula of engineering and architectural teaching programs at Swedish universities and university colleges have responded to the apparent and increasing demand for BIM competences in industry. The study relies on a survey of 10 universities and 8 university colleges that provide engineering and architectural teaching programs at a master’s and/or a bachelor’s level. The findings show that bachelor’s engineering programs at university colleges generally have adopted BIM into the curricula to a somewhat larger extent compared to engineering programs at a master’s level. The BIM-adoption in architectural programs is, however, significantly limited. Further, the degree of BIM-adoption differs significantly between the respective teaching programs. Only few universities have adopted BIM as an integrated subject in courses that deal with general construction related issues. The predominant approach is to implement BIM-subjects as discrete teaching modules, i.e. stand-alone courses, rather than as a cross disciplinary aspect implemented in a number of the existing courses. Besides, a considerate mismatch is identified between the technical characteristics of the BIM curricula at universities and the process-oriented approach to BIM represented by the industry. Thus, the universities would benefit from a closer collaboration with the industry in BIM-related matters and they need to take on a strategic approach to BIM at an overall university or program level in order to avoid isolated BIM initiatives at a single course level.

    Construction Innovation Systems - A Sector Approach2005Inngår i: Understanding the Construction Business and Companies in the New Millennium / [ed] Kalle Kähkönen & Martin Sexton, Helsinki: VTT – Technical Research Centre of Finland & RIL – Association of Finnish Civil Engineers , 2005, s. 203-213Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Recent studies depict the general need to increase and improve innovation in the construction industry. Innovation processes are traditionally described and analysed either on a macro level or a micro level. Production in construction is basically project oriented, as opposed to manufacturing industries for which most of these theories are developed. It is not fully sufficient to study innovation from a micro or a macro level due to the effects of the project orientation and the large number of actors in the construction industry. The objective of this paper is to present a model of the construction innovation systems from a sector systems approach. The study rests upon findings in the area of innovation systems in general and construction innovation systems in particular on one hand and construction sector systems analysis on the other. This paper presents arguments for the development of activity based innovation systems at a construction sector level.

    Transport av volymelement: Förutsättningar ur ett företags perspektiv2011Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Building with volume element is relatively new and has started to increase more and more. The regulations that exist to regulate and determine how the transports of volume elements are to be conducted are diffuse and not very well adjusted to address the issues with transporting volume elements. Today there are a number of instances that a company has to turn to in order to get a somewhat different view, what regulations say and interpret it in order to know what applies and not applies regarding the transportation of volume elements. regulations. The rules that are in place make it tough for the volume element producing companies to develop and continue to be active on the market. New stricter laws regarding environment safe building leads to the volume elements getting larger which makes it even harder to transport them from a law and rules point of view.

    Hantering av ändrings- och tilläggsarbeten inom byggindustrin: En komparativ studie för en ökad produktivitet inom byggbranschen2018Independent thesis Basic level (university diploma), 180 hpOppgave
    Abstract [en]

    With the housing shortage in Sweden today, effective solutions to the problems that arise are required. One of the issues in almost every construction project is change orders which often causes additional work and could negative impacts on the project such as reduced productivity; it could cause rework which could affect the working environment and increase the project cost. This report will review an alternative method of managing change work called “TvåTågsPrincipen” (TTP). What characterizes the method is that you produce in two teams, a production team that strives for continuous production, and a second team that comes in afterward as the production has passed from a moment or building component to carry out all changes and additions.  After several interviews with people within construction following conclusions were drawn: the method can bring both positive and negative effects to a project, and both are important to keep in mind. Examples of positive impacts could be accordingly: higher productivity, better working environment and lower costs. Incorrect use of the method could result in larger change orders, greater environmental impact and more material usage.

    Critical Path & Line of Balance: Olika byggprojekt kräver olika planeringsmetoder2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The construction industry is currently known for projects often being delayed. Since planning is very important for the whole building project, it is very important that this is done correctly. More time should be put to plan the different projects so that the project should go on as smooth and efficient as possible. By using improved planning methods, you can contribute to a more efficient production on the construction site with less disturbances and corrections of errors.

    The purpose with this study is to compare the two planning methods, Critical Path and Line of Balance, and compare its strengths and weaknesses with each other. Hopefully, this study also contributes to development opportunities in planning in the construction sector. The result of the study has shown that Critical Path is a well-developed method that is best suited to non- repetitive projects such as construction of villas, schools and other unique projects. Line of Balance is better suited to projects with repetitive activities, for example construction of highways or the production of high-rise buildings.

    Procurement and Governance Choices for Collaborative Infrastructure Projects2018Inngår i: Journal of construction engineering and management, ISSN 0733-9364, E-ISSN 1943-7862, Vol. 144, nr 8, artikkel-id 04018071Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Collaborative approaches to infrastructure procurement are increasingly popular around the world due to their potential to provide improved project performance compared with more traditional approaches. The problem is that project outcomes continue to be unpredictable. Previous research has shown that this is the case regardless of whether the chosen procurement approach is based on price or non price selection of the project team. This is a major choice that clients make, but the presented research shows that governance choices for project execution are more important. This is significant because clients tend to focus more on procurement choices and typically do not differentiate governance based on those choices. This needs to change, and the authors show that optimal governance configurations vary on the basis of the chosen type of team configuration. For example, three specific governance arrangements for workshops are highlighted for single teams, and two specific governance arrangements for risk/reward sharing are highlighted for multiple teams. This study identifies governance actions that are associated with superior time and cost outcomes on collaborative infrastructure projects in Australia run by experienced public-sector clients under the two procurement scenarios. Based on a survey of 320 senior managers, independent sample t-tests were conducted to compare the application of governance actions among three distinct groups of projects, based on type of team selection and type of project outcome. The study provides evidence of the most effective approaches to project governance in a country that is a world leader. The results provide much needed recommendations for improved project performance based on large-scale quantitative analysis, which before now has not existed. Overall, the study recommends more attention be paid to noncontractual governance under both approaches to team selection, although the specific actions recommended vary. © 2018 American Society of Civil Engineers.

    Modernisering av en fotbollsarena: Örjans Vall2012Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The purpose of this study is to show the technical building requirements for modern arenas inSweden. The study will also create an understanding of how the requirements affect theSwedish football arenas which are affected by the regulations valid from 2014. As one of theSwedish football arenas there is Örjans Vall located in Halmstad. The aim of this study is todevelop alternative solutions regarding the technical problems Örjans Vall is facing 2014,when the new arena requirements for “Svensk elitfotboll” are taken into use. The solutions aremeant to be seen as suggestions which can inspire and guide the future planning for themodernization of Örjans Vall.In order to present a suggestion with technical building solutions the study contains differentphases. The first phase is an evaluation of the arena requirements and criteria, with focus onthe technical building requirements, which are of importance when creating solutions forÖrjans Vall. The second phase is a review of the arena situation in Sweden. The last phase isan evaluation of Örjans Vall made towards the previous evaluation of the requirements andcriteria as the basis.The evaluation of Örjans Vall shows which technical building defects the football arena have.A rebuild and expansion of Örjans Vall is essential and needs to take place before 2014 unlessan exemption is issued. When all the parts in a complete suggestion should be consideredfollows a discussion where each area is treated separately. All areas will then form the basisof a complete suggestion for how a future Örjans Vall could be designed. The basis for thediscussions are simple solutions were practical suggestions are presented. In the areas where asimple solution does not exist, other arenas in Sweden will be considered to inspire theproposal.The solutions include the defects in different areas but also renovations and extensions of thebleachers where the main defects are shown. The report presents four alternative renovationsand extensions of the bleachers where an overall proposal is developed to meet the spectatorinterests.

    Utökad samverkan med leverantörer: - Partnering, en lönsam möjlighet i byggindustrin?2013Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The construction industry has been heavily criticized in the past few years for its development of productivity compared to the manufacturing industry. In 2009 the Social Care Center developed a report that treated och criticized different errors within the construction industry. For instance competence, construction errors and performance had showned bad results which had to be improved. A common sentence within the building industry is that ”every project is unique”.

     

    Today it’s common for a construction company to have costs for material and services which exceeds two-thirds of the total cost. The greater part of the total costs therefore does not lie within the companies internal organisation, but at the suppliers. Studies showed that external costs will increase in the future.

     

    New working methods from the manufacturing company, like Lean Construction and Partnering are starting to establish more and more in the building industry. The larger companies have learned how to use this new way of working but also the medium sized companies have started to show their interests for these methods that will work in a way of preventing problems, finding solutions and shrinking the costs.

     

    The construction company, Jonab, showed their interest for partnering and through earlier cooperation with Halmstad University it resulted in this final thesis. The scope of this thesis is to investigate with neutral view, Jonab’s business relationship focusing on the suppliers. From the perspective of partnering, we’ve given Jonab an overview over their relationships and recommendations on how to improve it with the use of partnering.

    Abstract [en]

    This thesis has been developed inassociation with Strängbetong AB, Sweden.

    A few years backCementa AB introduced a new type of cement on the Swedish market: Byggcement,which is a Portland Limestone Cement. This type of cement is better for theenvironment and cheaper than Rapid Hardening Cement which is used today at SträngbetongAB.

    Strängbetong AB isvery interested in a change of cement in the factory and wants to know what ittakes to make a transition from Rapid Hardening Cement to Byggcement.

    This final projectaims at investigating how the workability and strength development are affectedby a transition from the existing cement to Byggcement and how we can change theproperties of the concrete by adding different types of superplasticizers. 

    Laboratory and factoryexperiments were made, to investigate the transition.

    Managing short-term efficiency and long-term development through industrialized construction2014Inngår i: Construction Management and Economics, ISSN 0144-6193, E-ISSN 1466-433X, Vol. 32, nr 1-2, s. 97-108Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There is a strong need for a productive and innovative infrastructure sector because of its monetary value and importance for the development of a sustainable society. An increased level of industrialization is often proposed as a way to improve efficiency and productivity in construction projects. In prior literature on industrialized construction, there are however neither many studies addressing more long-term aspects of innovation and sustainability nor studies within the infrastructure context. Organizational theory suggests that firms need to be ambidextrous and focus on both long-term exploration of new knowledge and Technologies and short-term exploitation of current knowledge and technologies, in order to achieve sustainable development. Therefore, an investigation of how both short-term exploitative performance objectives and long-term explorative development can be addressed when implementing industrialized construction in infrastructure projects was conducted. A case study consisting of four infrastructure projects shows that the main drivers for increased industrialization are of an exploitative nature, focusing on cost savings and increased productivity through more efficient processes. The main barriers to increased industrialization are however related to both explorative and exploitative activities. Hence, by managing the identified barriers and explicitly addressing both exploitation and exploration, industrialized construction can improve both short-term efficiency and long-term innovation and sustainability. © 2013 Taylor & Francis.

    This report that is written in cooperation with Peab Sverige AB, studies the information and knowledge management from the production support to the production management.

     

    The conclusion of this report is that to have a good and functional information and knowledge management it is necessary that the company has a good way of regain and handling experiences from its projects. The way to do this is to develop the managing system on the production management’s terms. It is also critical to find an easy way for the production management to use the system.

    Vad motiverar och engagerar yrkesarbetare i byggprojekt: Partnerings påverkan på motivation och engagemang2017Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Inom varje projektorganisation finns det olika individer som ska skapa en produkt av hög kvalitet enligt kundens krav och förväntningar. För att bedriva projekten på ett effektivt sätt med ett bra samarbete har partnering vuxit fram. För att lyckas skapa ett bra samarbete gäller det att motivera och engagera alla inblandade till att arbeta åt samma mål. Beteendet ändras dock inte automatiskt hos människor bara för att de arbetar i ett partnering-projekt. Kontinuerligt arbete krävs för att motivera och engagera individer under hela projektets gång. I den här studien kommer partnering hänvisas till ett arbetssätt för att uppnå samarbete, motivation och engagemang. Skapar projekten en arbetsmiljö som gör att anställda presterar på sin högsta nivå kan det leda till att produktionen blir effektivare. För att yrkesarbetarna ska prestera på sin högsta nivå är det viktigt att motivera och engagera dem under produktionen. Examensarbetets syfte var att undersöka hur yrkesarbetarna motiverades och engagerades och vad i partnering som kunde bidra med att skapa detta hos yrkesarbetarna. Studien har utförts med hjälp av informanter från Skanska, Hus Göteborg.

    Faktorer som gjorde att yrkesarbetarna blev motiverade var att de hade kul på jobbet och bra kollegor runt sig i arbetet. Det var också motiverande att vara delaktig och involverad i att skapa produkter med hög kvalitet. Många av informanterna menade att kundens mål och visioner var viktigt för att få möjlighet att skapa en produkt som når upp till förväntningarna. Genom att yrkesarbetarna får fokusera på mål och visioner samt vara med och sätta upp dem kan mer motivation och engagemang skapas. Partnering kan i teorin bidra till att skapa motivation och engagemang men det är upp till varje projektorganisation hur organisationen väljer att implementera samarbetsformen partnering i projektet. I resultatet kan inte något specifikt urskiljas kring vad det är i partnering som motiverar yrkesarbetarna. Det som motiverar yrkesarbetarna kan göras i alla projekt och det är upp till projektorganisationen men också varje anställd att skapa förutsättningar till att skapa en motiverande arbetsmiljö där de anställda upplever tillfredställelse och trivsel.

    Effektivisering av asfalttransporter: Enhetligt arbetssätt för styrning och tidsskrivning av asfalttransporter2013Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    The cost of transportation has strongly increased in the recent years, transportations which are a major part for the construction companies. Skanska Asphalt which is a part of Skanska Sverige AB has noticed that there are significant cost savings to be made with the purchasing of transports. The transports in this case is about asphalt, where the costs are about 10% of the outsourcing business turnover. The purpose of this thesis is to study the working practice that Skanska Asphalt are using today in controlling and time-writing, for the asphalt transportations. Resulting in recommendations on how to improve the working practice at Skanska Asphalt.

    This study was conducted with the help of a number of interviews with Skanska’s employees and with suppliers of transportation to describe the practices which are being used in during the asphalt transportation. In the construction industry, every project is different and varies. For every project there is a production manager in charge from and scheduling to the ordering of transportations. For ordering asphalt transportations it’s common today for the production manager to make calls directly to individual drivers or to the management for the contracted transportation suppliers.

    It’s mostly common in time-writing to use hand-written notes, but there are also times when the drivers are using PDA for which the transportation management endorses the correctness of drivers information. The major problem is that the charged time for transportation is too high compared to the actual time, because drivers tend to round up the time-writing to the full or half an hour.

    Efficiency enhancement within Skanska is important and a proposal for improving working practice that can lead to cost savings is to introduce a different type of tariff. This requires closer cooperation and higher demands on the suppliers of transportation. For this system to work, it’s important to get system support from the suppliers.

    With improved internal communication between production managers it’ll result in further efficiency enhancements being found and Skanska will be able to increase the utilization of the asphalt transportation. The planning of the asphalt transportations could improve even further if it had existed any kind of calculation template. If Skanska informs the transportation suppliers in the early stage before the project kicks off with some form of planning calendar with the correct number of vehicles, will make it easier for transportation providers to meet Skanska's transportation needs.

    BIM - Förvaltarens Framtid2010Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    For nearly twenty years people have been talking about Product models, but given that the building industry is so conservative, it is hard to implement new working methods. Product models are these days known as Building Information Modeling, BIM. People often say they work with BIM but they often forget the most important part, the information. A 3D model should be linked with characteristics and information. Information that can be invaluable for the facility manager.

    We have a vision that in the best of worlds the facility manager would be able to "walk" into the model and see what kind of installations are inside the wall or in the roof. You should be able to point at an object and gain complete information about operation and maintenance off the installation. You should also be able to gain information such as the name of the product and article number if you have to buy a new one. That’s why in our thesis we want to highlight the possibilities for the facility manager.

    In order to have high achievements with BIM, coordination is highly needed. All participants in the construction process have to work together at an early stage; they must have the possibility to affect the stage of inquiry. By having the facility manager connected to the process at an early stage, other members have the opportunity to understand what’s expected from them. In the same way the facility manager will understand if any of the requirements are unreasonable or difficult to solve. Planning must be allowed to cost money. A well planned project can later save a lot of money due to less problems at the building worksite. In a well planned project there will be less changes and less additional work. The key words are Coordination and review.

    During the facility management stage there are great opportunities to save money with BIM. The benefits of BIM have been shown and larger facility companies demand a model that work in the facility management stage. The greatest advantages are gained by the visual model that gives a greater understanding and a better base for decisions. There are also great advantages in more effective processes, better quality and better documentation for maintenance, operation, future rebuilding and future sale.

    To be able to get a good image of BIM, how it is used today and what expectations there are, we have interviewed facility managers, system manager and BIM experts. We have also researched information in reports and articles.

    The Construction Process Forum was initiated by the Construction Council. The Construction Council is an organisation which supports cooperation between universities and the construction industry. The Construction Process Forum was formed through that chosen key persons were asked to come up with suggestions on how to create a more effective construction process plus how to improve the image of construction. The aim was also to increase the awareness among the participants of Construction Process Forum. This report narrates the result of one years work within the Construction Process Forum. The focus of this first year was the construction site and the changes needed of the construction process to create better conditions for the construction site. The Construction Process Forum ended with the formulation of a plan of action for the development of construction.

    Project Assessments in Construction and Real Estate: Analysing management of end-user needs and ensuring performance in the building life cycle. CREDIT Report 42010Rapport (Annet vitenskapelig)
    Abstract [en]

    In this report a generic model for the capture and assessment of end-user requirements and needs, the CREDIT carpenter model, has been developed. The main determinants of the model is the need for the project organisation (including the facilities management organisation) to ensure a thorough understanding of the end-user requirements and needs as well as an assessment through out the project process. The end-users and the project organisation are often working in two different value chains. This, among other things, means that they may not share a common understanding of the process. Apart from just assessing to what extent the requirements and needs has been achieved it is important to assess the process of accomplishing the desired result. This way it is possible to learn from what has worked well and what has not. There is some variation in what and how it is being assessed depending on what type of building it is. Assessments on housing are more inclined to focus on softer aspects, for example perception etc. In the other cases there are, generally, a more technical perspective. It may be an affect of how knowledgeable the users are. In regard to housing the users have possible less experience of construction and communicating their needs than in the case of offices etc. There is also a notable difference between approaches and interest on what to assess in the different countries. Sweden has a much more soft approach and an ambition of getting as many as possible to understand what is being assessed and for what reasons while Finland has a much more technical and measurable approach. The clients, naturally, play a large part in the construction process, also when it come to capturing and transferring the requirements and needs of the end-users. It is mainly the clients that initiate it. Maybe more surprisingly, they do perform a lot of the work themselves as well. Designers play an important role as do known end-users as well. During the project it is mainly the client that initiates the assessments, but the actors of the project process, designers and producers that perform it. Evaluating the degree of fulfilling the requirements and needs as well as assessing the process to enable learning is again mainly a client action both initiating and performing, the rest of the actors do not engage to any larger degree. The processes from begin of the brief to the end of construction have well developed routines as a part of the project management system. These routines are good enough to successfully fulfil the studied project and the control of the process in order to get internal efficiency in the short run perspective. But there is almost no case that shows any assessment tool that support feedback, the knowledge development and the innovation process which is important in the long-run perspective. The missing feedback is marked in the carpenter model. Found in the study there are two examples of tools that together may to some extent overrun this issue. Building Information Models have the potential of acting as an information carrier within a project, storing all types of information needed for assessing a number of different aspects. The main issue is to get the right information and presenting it in a way suitable for the target group. This is done in the case of Falk in Skanska (in Norway). It is a system gathering and presenting a multitude of KPIs, from a number of different systems, in an easy to understand layout.

    Situationsanpassat ledarskap för byggproduktion2013Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    A large cost at the construction sites today is the labour cost of the workers. But unfortunately the worker potential is not used to full. It is not unusual to take into a count with a work-­‐place-­‐additional-­‐time of 50% in some cases. By increasing the workers' motivation and responsibility for their tasks may reduce the time considerably, which also increases the potential for greater gains in construction projects.

    By using the situational leadership may the workers level of maturity develop entirely. They become broadly self-­‐propelled with high efficiency and the construction leader can after that get more time for his/hers own tasks.

    The work gets done more efficiently and the potential for greater profits increase. Good leadership at the construction site also improves the working environment for all. More people may be motivated to go to work and such sickness absence may decline.

    Abstract [en]

    A degree thesis about quality control and assurance in construction. Made in cooperation with Wästbygg. An analysis was made of the self-monitoring control that is conducted during the construction. The data was collected from interviews from personnel employed by Wäsbygg as either work-leader, project-manager or quality- and environmental-coordinator. During the study there was also a review of the literature in the subject. From the data collected it was found that lack of commitment and poor attitude about the procedure were some of the main reasons why it doesn't work.

    To improve the self-monitoring control during construction is it necessary to execute it more consistently. Have clearer definitions for what self-monitoring control to make it easier for workers to conduct it. The workers also needs extra training and education in the subject to preform it better. The management on site does also need to participate more to show that it's a important procedure.

    Adoption of a Working Environment Innovation: “Rollout Bar Carpets”2015Inngår i: Proceedings CIB W099 Belfast 2015 / [ed] Mike Behm & Ciaran McAleenan, Downpatrick: EEI Publishing , 2015, s. 417-425Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Work environment problems associated with reinforcement work at constructions sites are often great and difficult. This applies especially to the ergonomic situation. The situation is particularly difficult in connection with reinforcement in horizontal structural elements such as slabs and foundation slabs on the ground, where several of the most difficult load factors occur. Since about 15 years there is an innovation (rollout bar carpets) available on the Swedish market. This innovation can many times be used at these structural elements and gives both time savings and working environmental benefits. Despite this the innovation has been and is adopted rather seldom. The reasons for this have been studied through semi structured interviews with with design-engineers, site-managers, workers and persons working at a reinforcement manufacturing company. The main results from the study are as follows: i) Rollout bar carpets have a potential of improving both work environment and time consumption on site. However, this may not be enough in itself to achieve a general adoption of the technology. ii) The implementation and adoption of innovations in construction may be more complex than the novelty of the innovation may suggest. This is due to the contextual delimitations of a project-based industry and the different roles in the construction process.

    Success Factors Related to Industrialized Building in Sweden2014Inngår i: CIB International Conference 2014: W55/65/89/92/96/102/117 & TG72/74/81/83: Construction in a Changing World: Book of Abstracts / [ed] Dilanthi Amaratunga, Richard Haigh, Les Ruddock, Kaushal Keraminiyage, Udayangani Kulatunga & Chaminda Pathirage, Salford: School of the Built Environment, University of Salford , 2014Konferansepaper (Fagfellevurdert)
    Abstract [en]

    During the last decade there has been intense discussion in Sweden about industrialization in construction. The discussion has focused on industrialization in connection with erection of multi dwelling houses. It has been argued that industrialization is a key factor as regards obtaining affordable high-quality dwellings. During the last ten years some new industrialization concepts have been developed and tested. Even though some concepts have failed others have been more successful and are under further development. Industrialization is a reality within the Swedish construction sector and can be assumed to play an important role in the future as regards obtaining affordable high-quality dwellings. In this paper success factors related to four industrialized building concepts/methods are described and discussed. The review is based on available literature relating to each of the concepts/methods/producers, from which it was possible to ascertain success and failure factors.

    Introduction of sustainable low-cost housing. Experiences from a demonstration project viewed from an innovation diffusion perspective2016Inngår i: Proceedings of the CIB World Building Congress 2016: Volume V - Advancing Products and Services / [ed] Nebil Achour, Tampere: Tampere University of Technology, 2016, Vol. 5, s. 431-442Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The purpose of the study is to describe and analyse, from an innovation diffusion perspective, factors important when using demonstration projects as a tool for introduction of sustainable low cost housing. The study is focused on Ethiopia, a country with big challenges as regards population increase, lack of resources, deforestation, land erosion and a general need for better and sustainable housing, especially in rural areas. The study is furthermore focused on the adobe technology as a more sustainable alternative to the traditional building technology which is very timber consuming. Many attempts have been made to introduce this technology with the use of demonstration buildings. A great part of these attempts have failed, some have been successful. In order to study and discuss important factors in connection with the use of demonstration buildings, a project executed some years ago in southern Ethiopia has been analysed. The study is based on findings collected during and after the erection of these buildings mainly through practical tests, interviews and observations. From a technical point of view this demonstration project was successful. It was possible to develop an appropriate production technology and the result was buildings with a good standard and good function. Experiences up to now indicate a good durability. From an innovation diffusion perspective however the demonstration buildings have not fulfilled their purpose. The impact in the region seems to be very small. The conclusion in the paper is that the reasons behind this failure mainly are: (1) Lack of clear and visible relative advantage in comparison to the traditional building technology. The supply of construction timber in the area in question is still good. (2) Lack of a champion advocating the technology by using the demonstration buildings and thereby giving the message to the society that the technology is valuable and trustworthy. (3) Lack of continuity in the demonstration efforts, as a result of the lack of a champion.

    Inblandning av flygaska i betong - inverkan på tidig hållfasthetsutveckling vid låg temperatur2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Detta examensarbete har haft till syfte att undersöka utvecklingen av tryckhållfasthet vid låg

    temperatur hos betong med olika innehåll av flygaska. Tryckhållfastheten har bestämts genom

    provtryckning av kuber med åldrar upp till 28 dygn. Provningen har utförts på tre delserier;

    delserie 1 utan innehåll av flygaska, delserie 2 med 7,5 % och delserie 3 med 15% flygaska räknat

    på cementvikten. Kuber från dessa delserier har förvarats under olika temperaturförhållanden;

    från lägst ca 7 °C till höst ca 20 °C. Temperaturutvecklingen i representativa kuber har

    kontinuerligt registrerats. Tryckhålfastheten har bestäts efter 1 dygn, 2 dygn, 7 dygn och 28

    dygn.

    Resultaten frå de utföda mäningarna ä i huvudsak föjande: (i) Inblandning av 7,5 % flygaska ger

    en reduktion med 8,3 –11 % av hålfastheten vid hädning vid ca 20 °C och vid provning vid olika

    åder. Inget klart samband mellan provningsåder och reduktion. (ii) Inblandning av 15 % flygaska

    ger en reduktion med 22,1 –24,6 % av hålfastheten vid hädning vid ca 20 °C och vid provning vid

    olika åder. Inget klart samband mellan provningsåder och reduktion.

    Pågrund av svåigheter att styra temperaturen hos provkropparna påett noggrant sät visade det

    sig svåt att dra sära slutsatser avseende inverkan av säkt hädningstemperatur. Föjande kan

    dock sköjas i de uppmäta resultaten. (i) Inverkan av reducerad hädningstemperatur minskar

    med öande åder. Detta gäler oavsett halten av flygaska. (ii) Lå temperatur i tidigt skede (de 7

    fösta dygnen) ger en föhöd sluthålfasthet. Detta gäler oavsett halten av flygaska.

    Fö de olika kuberna som provtryckts har den ekvivalenta mognadsådern beränats med hjäp av

    uppmäta temperaturer. Detta har gjorts dels med TT-faktormetoden, dels med hjäp av

    Ahrreniusfunktionen. Baserat pådetta har teoretiska hålfasthetsutvecklingsfunktioner formulerats

    fö de tre serierna. Genom dessa funktioner har inverkan av flygaska och temperatur kunnat

    analyseras. Dessa analyser tyder påföjande: (i) En inblandning av 7,5 % flygaska ger en reduktion

    av den relativa hålfastheten med 5 –10 %. En minskande temperatur och en minskande åder ger

    minskande inverkan. (ii) En inblandning av 15 % flygaska ger en reduktion av den relativa

    hålfastheten med ca 20 %. Detta gäler oavsett åder och temperaturnivå

    BIM Inertia: Contracts & Behaviours2015Inngår i: Building Information Modeling: Applications and Practices / [ed] Raja R. A. Issa & Svetlana Olbina, Reston, Virginia: American Society of Civil Engineers (ASCE), 2015, s. 107-134Kapittel i bok, del av antologi (Annet vitenskapelig)
    Abstract [en]

    Whilst Building Information Modelling (BIM) promises significant improvements in construction quality and efficiency, current contractual models do not encourage its use; indeed actively inhibit the collaboration at its core. To help bring BIM into the mainstream, it is claimed we need to re-craft existing contractual relationships to facilitate collaborative decision making and to equitably allocate responsibility among construction participants. This chapter looks at the case of Sweden and aims to identify and appraise observed hindrances to BIM collaboration and digital information stewardship. It presents an understanding of the connections between the commercial environment and contractual provisions that regulate the party’s business relationships and the resultant procedural and behavioural phenomena that can be viewed to thwart BIM collaboration and degrade the value or integrity of digital deliverables. The study then, in a more general context, asks what we can learn here that may have wider application through consideration of suitable BIM collaboration support mechanisms that may reduce or remove collaboration barriers, induce open, sharing behaviours and support the creators and users of digital information. Methods employed include a critical review of existing contract forms, synthesized with focus group interviews (FGIs) with representatives from diverse AEC disciplines. Results indicate that a number of systemic difficulties exist that can create an inertia which can be traced through behaviours and circumstances to contractual provisions. An understanding of such difficulties is presented and a consensus emerges on a number of key supporting mechanisms that may better facilitate meaningful early BIM collaboration and oil the wheels of communication without recourse to re-writing the rule-book.

    National and International Benchmarking: CREDIT Report 52010Rapport (Annet vitenskapelig)
    Abstract [en]

    This report summarizes findings and recommendations from 24 case studies from seven participating countries addressing performance indicator benchmarking at a sectoral, national or international scale. Their distribution in scope is: – benchmarking systems and indicators (4 case studies) – offices (7 case studies) – housing (6 case studies) – school and nursery (4 case studies) – shopping centres (3 case studies). In addition, actual performance benchmarking was done between six Finnish and Norwegian office buildings using CREDIT Key Performance Indicators and a web-based benchmarking tool, developed in CREDIT for that purpose. Some good benchmarking practices exist already at a national and international level. They focus on process issues, investment aspects and environmental properties. These existing schemes contribute to the CREDIT framework, but don't cover well the performance dimension. There isn't yet any commonly agreed European Key Performance Indicator system, or building and real estate performance indicator standard. CREDIT made a contribution to their development from the Nordic/Baltic perspective. It also provided valuable input from the performance and social sustainability point of view to existing economic and environmental oriented schemes that are continuously updated and amended. CREDIT made progress in performance indicator framework and actual performance indicators and tools, some of which were already tested in the case studies. Understanding on existing benchmarking schemes is also improved. The results of CREDIT WP6 performance indicator benchmarking at a sectoral, national or international scale can be exploited in number of ways, such as – the front runner companies adopt the core performance indicators in their practices and influence in forming their use a sector based practice – further development of standardization, tool development (IFCs), benchmarking schemes and rating systems makes use of the results.

    "En kvinna kan inte utföra en mans arbete": En studie om hur kvinnor och mäns normer & värderingar påverkar jämställdhet inom hantverkaryrkena2019Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    The construction business is one of the most male-dominant industries in Sweden, where the majority of the workers are men. Since the industry is associated with dirt, provocative jokes and heavy lifting many tend to picture a man as a construction worker. This unfortunate picture has set a tone on the society and in the minds of young girls who believe that they don't belong in the construction business. Those who are affected the most are the craftsmen, which is the part the authors have decided to focus on. Previous studies has shown that women who works in a male-dominant work environment tends to be exposed to sexual assault, stress, less development opportunities and different standards than their male coworkers. This inspired the authors to examine if this applies to the craftsmen and if so, how can one make the craftsman profession more appealing to women?

    The purpose of the study is to examine any possible problems attached to the low amount of female craftsman and the benefits that would occur if the amount got higher. To execute this study the authors have chosen a qualitative methodology. Previous studies have helped to form eventual problem formulations and questions asked in the semi-structured interviews that where conducted by the authors. The discussion and analysis results in a list of changes that must happen in order to appeal more women to the craftsman profession. In conclusion, changes that must happen will take time and one can only hope that the next generation will grow up without the stigma the craftsmen suffers from today.
