Mervärden av BIM : En analys av implementering av BIM i byggproduktionen

Sammanfattning: The past 60 years, many industries have developed exponentially regarding digitalisation and they have adapted to the technology quickly. However, the construction industry has a linear development and has almost remained unchanged over the past years. It is still common to use printed plans at construction sites and raise buildings based on 2D drawings even if there are detailed 3D models accessible. There are great opportunities for development of the construction industry, but not many companies have succeeded in maximizing the outcomes due to limitations of external factors. The use of Building Information Modeling (BIM) needs to be standardised in the construction industry, in all phases. The thesis aims to investigate the obtained benefits of implementing BIM at construction sites. The thesis presents the topics of the construction process and BIM, and it accounts the results of the study based on a qualitative analysis. The responses from the interviews have been interpreted and summarised into a result, which are also confirmed by a background research. The study resulted in many benefits from the implementation of BIM at construction sites. To summarise, the benefits are: better information management, clearer communication, more efficient planning, reduced costs and increased quality. The study also shows that each benefit, in turn, results in additional benefits. The conclusion is that, in order to gain from the benefits, companies must invest in competence and resources. It is also necessary to demand more from authorities in order to make digitalisation a standard in the construction industry. There are great opportunities for an automatised construction process in the future. Furthermore, it can be speculated whether this will also lead to robotisation of the industry, 3D printing of buildings and using AI to design buildings. The first step for the construction industry is to catch up with the other industries is to standardise the use of BIM throughout the construction process.
