Purpose: Digitalization has progressed with big steps in the recent decades. This has been reflected in the construction industry where “Building Information Modeling” has been implemented. The implementation has entailed some complications for designers, existing established working methods are opposed to new software and digital instruments. There are also differences in skills between the designers who have worked long in the industry and those who are newly graduates. Those who have a long working experience do not have as high digital competence as the newly graduated but they have a much broader practical knowledge. The purpose of the study is to analyze how the implementation of BIM has affected constructors about their professional/technical competence and to develop measures to increase the digital competence so that constructors can fully utilize their professional competence. Method: The method used in this study is interviews. The study will be carried out through qualitative methods where the interviews are semi-structured. Several interviews have been conducted at two consulting offices in Uddevalla and Trollhättan. The interviewees are constructors with experience of construction before BIM and constructors with experience of BIM from their education. Findings: The study shows what factors that have contributed to difficulties in the working method BIM. Digitalization in general has affected the workflow that constructors carry out because they replace old habits. The construction industry is constantly changing, and older constructors can adapt to the system by training. This creates difficulties, which means that they require help from employees with a better digital competence. A higher digital competence is necessary to keep up with the incubation. Therefore, through good leadership, you should help older constructors, this is done by motivating them to learn how to use software to design, communicate and organize. Implications: There is a lack of digital competence in several constructors without education of BIM. There are also complications between constructors due to differences in skills and different perspectives on their problem solving. The study proposes that a BIM-coordinator is needed to steer the implementation of BIM in the right direction in a company and that a broader investigation must be carried out. Limitations: The report’s survey method was only limited to one company in addition to two offices, which meant that the perspective in the study was limited. The study focuses more on identifying the problem and finding a solution to the problem, it does not focus on how the measures should be carried out and what consequences this would have on a company.

Compared to other industries, the construction industry is slow to take advantage of the benefits of digitalization. There are many different parties involved in projects, which makes it a versatile but also fragmented industry, which in this case is not to its advantage. Building information modeling (BIM) is a tool that could improve the cooperation between these parties and which has many other benefits associated with it, such as time- and cost savings. Quantity take-off in BIM is something that can be carried out at a low degree of maturity and is considered to be one of the most useful working methods that BIM enables. Despite the many benefits that studies have shown, many companies in the construction industry have still not fully implemented a working method where BIM is used for quantity take-off.The purpose of the project is to investigate the BIM use among parties in the Swedish construction industry. More specifically, this study will examine the working methods of medium-sized construction companies with quantity take-off. Since the work with quantity take-off has been shown to be linked to more basic BIM use, this factor can be seen as a good indicator for the development of BIM within companies. Medium-sized construction companies have been chosen as they are a good representative of the large mass of parties in the construction industry who have both the capacity and the finances to implement BIM. Furthermore, this project also aims to locate the difficulties in using these digital working methods for quantity take-off.The study is performed as a qualitative case study where ByggDialog AB exemplified a medium-sized construction company in the construction industry. In semi-structured interviews, employees were asked to answer questions concerning the subject of the study.The results of the study have shown that the willingness to develop working methods with BIM at medium-sized construction companies exists, but that visions and ambitions are limited by the adjustment costs that a BIM-implementation would entail. The fact that there are no requirements or demands from customers is another factor that contributes why BIM is not used more today. As a result of the fact that the customers today are not prepared to finance a BIM-implementation, the development is not driven further within the studied company.In this case study, we have identified that the studied medium-sized construction company does not use BIM for quantity take-off. This is not due to that the contractors do not want to, but because it is difficult to motivate that a BIM-implementation would cover the costs involved. This study therefore indicates that in the short term it is not profitable to implement BIM as it entails large conversion costs for companies. / Byggbranschen är jämfört med andra branscher långsam på att utnyttja de fördelar som finns med digitalisering. Det är många olika aktörer inblandade i projekt vilket gör det till en mångsidig men även fragmenterad bransch, vilket i det här fallet inte är till dess fördel. Building information modeling (BIM) är ett verktyg som skulle kunna förbättra samarbetet mellan dessa aktörer och som har många andra fördelar kopplat till sig såsom tids- och kostnadsbesparing. Mängdavtagning i BIM är något som kan genomföras vid en låg mognadsgrad och anses vara en av de mest användbara arbetsmetoderna som BIM möjliggör. Trots de många fördelar som studier påvisat har många företag inom byggbranschen fortfarande inte fullt ut implementerat ett arbetssätt där BIM används vid mängdavtagning.Syftet med examensarbetet är att undersöka BIM-användningen hos aktörer i den svenska byggbranschen. Mer specifikt kommer detta examensarbete att granska medelstora entreprenörers arbetssätt med mängdavtagning. Eftersom mängdavtagning har visats vara kopplat till mer grundläggande BIM-användning kan denna faktor ses som en god indikator för utvecklingen av BIM inom företag. Medelstora entreprenadföretag har valts då dessa är en god representant för den stora massan av aktörer inom byggbranschen som både har kapaciteten och ekonomin att implementera BIM. Vidare syftar detta examensarbete också till att lokalisera svårigheterna vid användning av dessa digitala arbetssätt för mängdavtagning.Studien är utförd som en kvalitativ fallstudie där ByggDialog AB fått exemplifiera ett medelstort entreprenadföretag i byggbranschen. Medarbetare har i semistrukturerade intervjuer fått svara på frågor som berör studiens ämne.Resultatet i studien har visat att viljan att utveckla arbetssätt med BIM hos medelstora entreprenadföretag finns men att visioner och ambitioner begränsas av de omställningskostnader som en BIM-implementering skulle medföra. Att det inte finns någon efterfrågan eller krav från beställare är en annan faktor som spelar in i varför BIM inte används mer idag. Som en följd av att beställarna idag inte är beredda att finansiera en BIM-implementering så drivs inte utvecklingen vidare inom det studerade företaget.Vi har i denna fallstudie identifierat att det studerade medelstora entreprenadföretaget ej använder sig av BIM vid mängdavtagning. Detta beror inte på en ovilja hos entreprenörerna, utan för att det är svårt att argumentera för att en BIM-implementering skulle täcka de kostnader som det innebär. Denna studie indikerar därför att det på kort sikt inte lönar sig att implementera BIM då det innebär stora omställningskostnader för företagen.
