Abstract: An increasing amount of information is packed into Building Information Models (BIMs), with the 3D geometry serving as a central index leading to other information. The Three-Dimensional Information Retrieval (3DIR) project investigated the use of 3D visualisation to formulate queries, compute the relevance of information items, and visualize search results when using such models. Initially, workshops identified the needs and aspirations of the users of BIMs. Based on these, a graph theoretic formulation was created to inform the emerging system architecture. A prototype was then built using a commercial BIM platform to incorporate the enhanced information retrieval functionality. This enabled relationships between 3D objects to be used to widen a search, whereby relevant information items linked to a related 3D object (rather than linked directly to objects selected by the user) are still retrieved, but ranked lower. An evaluation of the prototype demonstrated that a tight coupling between text-based retrieval and 3D models could enhance information retrieval from 3D modelling environments. However, refinements to enable this do add an extra layer of complexity.
