ABSTRACT
In recent years the concept and use of a Building Information Modelling System (BIMS) has acquired increasing attention in asset management. The core of BIMS is a 3D-model of the assets under consideration. For new structures this is not a problem as they will usually be designed by means of 3D models. For existing structures on the other hand, this poses a challenge, as 3D models of the structures will usually not exist. In recent years COWI has been involved in a number of projects where different approaches have been used to establish 3D-models of existing infrastructure assets. Two such projects will be described in this paper. Further prerequisites for using BIMS on existing structures are also presented. This includes existence of an object hierarchy as well as availability of relevant as-built documentation. Further, this paper discusses the similarities and differences between a BIM system and an Asset Management System (AMS).
