Enriching the 'I' in BIM: A BIM-Specifications (Bimspecs) Approach

This paper conceptualizes a framework for bridging the BIM-Specifications divide by embedding project-specific information in BIM objects by means of a product library. We demonstrate how model information, enriched with data at various levels of development (LODs), can evolve simultaneously with design and construction using a window object embedded in a wall as lifecycle phase exemplars at different levels of granularity. The conceptual approach is informed by the need for exploring an approach that takes cognisance of the limitations of current modelling tools in enhancing the information content of BIM models. Therefore, this work attempts to answer the question, “How can the modelling of building information be enhanced throughout the lifecycle phases of buildings utilising building specification information?” LITERATURE REVIEW Problem Overview. Building Information Modelling (BIM), a process of digitally representing buildings in 3D, is redefining the world of construction (Azhar, 2011; Succar, 2009). Building specifications on the other hand, are a class of building information crucial to the lifecycle of buildings which capture information related to material quality and the associated workmanship necessary for project completion (Potter, 2002). Ongoing efforts in the construction industry are targeted at exploiting Building Information Modelling for increased efficiency and productivity gains. Indeed there is evidence that such efforts have given rise to industry-transforming outcomes as improved team communication through visualisation (Succar, 2009), as well as increased accuracy in building design and construction through clash-detection, cost
