Informationsbehov ur en BIM-modell för användning i fastighetsförvaltning

Sammanfattning: Purpose: As buildings become more complex, property management becomes increasingly complex. New demands are made on buildings environmental performance, risk management and new technology is introduced, which changes the property management industry. Problems with current property management methods are that the information for an efficient maintenance is difficult for the trustee, and the lack of interoperability between architects, constructor, client and trustee. The digital divide between trustees and other actors helps the trustee to reject the idea that BIM can be used in management. The aim for this rapport is to determine what information is to be required from a BIM-model to be to any use in the management process. Method: This work has been done through interviews and document analyses to answer the goal. Findings: There is a drive from trustees to switch to BIM, but the main obstacles are the lack of knowledge and influence at the start of construction projects, which means that the right requirements regarding the development and detailing of a BIM model can’t be set properly. Trustees know what information they need, but not how to set the right requirements without a specific standard. Implications: A lack of competence and knowledge about BIM at the trustees implies the need for a standard on the BIM-models level of detail and development for at all stages in the project, and all actors and researchers involved in the work. However, the trustees is aware of the information they need in their management system, which should be taken into account when a standard is being made. Limitations: The interview respondents came from different types of management companies, such as profit-making and non-profit-making, smaller and larger management companies, as well as trustees of residential, office, hall buildings and campus properties. Interviews with clients had helped make the work more relevant as it appeared from interviews conducted that the client plays a major role when demanding a BIM-model in a construction project.
