Sammanfattning: From an overview study published in 2014 it is concluded that although new information technology and standards are a strong driving force towards a more efficient and profitable facility management it is just as important to identify what types of information, in which manner, and to what extents the information is supposed to be shared to different business processes and disciplinary actors [1]. In the attempt to achieve a more automated facility management and integrated-life cycle approach of buildings the handover of building information is a major bottleneck [2]. Delimited to building services for HVAC, plumbing and electricity this study aims to investigate which needs related to installation information there are in facility management of buildings and that are possible and should be included in the handover from projects to facility management. Furthermore the study aims at in depth (through a case study) describe current ways of performing installation information handovers. New ways of working for the case study organisation according to higher levels of BIM maturity [3, 4] is described and analysed. From the results of a series of interviews (informants: [5, 6, 7, 8, 9, 10]) it is concluded that the two most valued sets of information related to building services are:  Warranty information: warranty start date, warranty period and warranty terms (description of what types of service and maintenance that are included in the acquisition of the asset). All three properties need to be nationally standardized.  Air quality in spaces: Space objects where occupants spend time should include information about the air types, its quantities and how the airflows are controlled over time in that space. Furthermore informants ask for a description of the designed function of the space and some ask for the number of persons the space is designed for. A national standardization of an information model describing the mentioned variables is necessary in the future. To be able to describe installed products regarding what (manufacturer, model and/or type) and where (location in the building) was almost as prioritized. Thereafter was the issue of the expected useful life of the products of concern for products with maintenance actions that would involve substantial costs. 3 The organization in the case study needs to move on to completely digital ways of working for enabling BIM. Additionally they need to state requirements on the structure and content of the objects in both the proprietary formats as well as on the open formats (IFC [11]) of the CAD models that are handed over to them from the projects. There is a possibility (but not utilized) for the organisation today to map IFC files to their facility management software system [12]. In the future they should utilize BIM model servers with cloud services [13] that are integrated with their facility management software system.
