The ambition for a more digitalized and effective line of business is large for building companies. It is of great importance, to the companies in the building sector, that the adaption of new tools and methods of working happen to secure their place in a modern and competitive line of business. BIM-building process is the tool the companies need to reach their ambitions.  One of Veidekke´s goals is to use BIM throughout the entirety of their projects. This work has with cooperation with Veidekke Sverige clarified what obstacles there are for the implementation of BIM in the building production an also to give propositions for actions to fix these obstacles. The study has mainly been done through half controlled interviews with key individuals and thru available literature studies.  The result of the study has shown that there are three main obstacles that have slowed the implementation of BIM in the building process. These obstacles are as follows: the level of detail of the BIM model, technical difficulties associated with software and hardware, and the human aspect.  The solutions to these obstacles have been brought forward regarding the position of Veidekke Sverige, in the line of business of building, regarding BIM, and are made up of our own speculations from past experiences and knowledge gathered though the course of the education.
