Digitalized Construction Project : To Build after a Legally Binding BIM-model

Detta är en Master-uppsats från KTH/Fastigheter och byggande; KTH/Fastigheter och byggande

Sammanfattning: Digitalization has become something of a buzzword in today's society and rightly so as it brings multiple benefits and opportunities. The AEC/FM industry has constantly lagged behind other industries in terms of change and development and is often regarded as conservative. Strongly associated with digitalization in construction are the concepts of Building Information Modeling (BIM) and Virtual Design and Construction (VDC), which partly include technology and models for integrated and model-based approaches to, for example, reduce fragmentation between project members who traditionally work independently of one another. In research, it is revealed that there are large gains with a successful implementation of BIM/VDC in projects and this is something that many companies in the industry are working with and seeking to develop. The purpose of the thesis is to investigate how the project team members have worked and how the working methods are perceived by them in a well-known construction project in Sweden, where they have taken a step further in digitalizing construction by building after a legally binding digital model instead of the traditional paper drawings. The subject is explored with a qualitative method, in the form of a case study, where a scientific literature study, interview study, and observations together form the basis of the study and these parts act as a basis for the discussion. The literature study covers previous research as well as concepts relevant for answering formulated research questions and concepts that emerged during the interview study that are important to understand for a qualitative discussion and, consequently, qualitative conclusions. In the interview study, 13 respondents were interviewed in so-called semi-structured interviews and all of them were involved in the case project. The findings indicate that the BIM-model can contribute to better communication, higher resource efficiency, better quality and, at the same time for a lower total cost of the project. Identified perceptions in designing a BIM-model and then building after the model instead of 2D drawings are predominantly positive. While advantages and opportunities are demonstrated by this way of working, new challenges and risks arise. This entails legal risks, technical risks and management risks. There are new types of errors that arise with a more detailed design.
