BIM is a tool with great potentials within several fields of application, but despite this there are still doubts about the possibilities to take on and integrate the use of BIM, especially in the building production. Lack of interest, complex applications and the need to reorganize processes are complicating the integration. This study discusses BIM as a digital aid in the building production where the ambition is to analyze how a contractor can convert visions about BIM into practical application in the building construction.

To achieve the ambition with this examination paper, a case study has been conducted at Peab in Jönköping where data has been collected through interviews, observations and a document analysis. This empirical data is analyzed along with a theoretical framework, which is created through a literature review.

Today, BIM is not established at Peab in Jönköping and the company stands in the presence of a change where BIM shall be integrated and become a natural way to work. The visions about BIM are that the company shall gain an improved position in the labor market, produce better documents and establish BIM in the building production. The BIM integration is a line responsibility where the line managers must create a culture for development, take responsibility and show commitment in the transformation. All project participants have to undergo education and the roles and responsibilities in the integrations must be identified. The visions and ambitions about BIM at the office must be transferred to the building production, to succeed with the integrations and create a collaboration that reduces the gap between the office and the construction site.

The conclusion is that an integration of BIM in the building production is possible, only when BIM is an established and natural work method in the design phase. To facilitate the integration of BIM in the building production at Peab in Jönköping, the information flow must be more frequent and continuous, the BIM model must be adapted to the users in the building production and a clear strategy must be framed before the projects, that currently are designed with BIM, reaches the construction phase.

This examination paper aims towards readers with prior knowledge in BIM and building technique, therefore the result is presented without further explanation about functions in mentioned softwares. Only one case company is selected to gain a profound insight and to clarify the connection between visions and practical application.
