Møller, Naja L. HoltenBansler, Jørgen P.2017-07-242017-07-242017Over the past decade, Building Information Modeling (BIM) – an advanced modeling technology and associated set of processes to create, develop, and analyze digital building models – has emerged as one of the most promising approaches for im- proving the performance of building projects. It has been heralded as a ‘digital revolution’ and it is expected to improve collaboration, productivity, and product quality throughout the building life cycle by providing ‘perfect information’ on which to base the design and construction (Crotty 2012). However, little is known about the use of BIM in practice, and it has so far not been studied from a CSCW perspective. In this paper we present prelim- inary findings from a field study of a large hospital construction project in Denmark. The project is in its early phases, so the focus is on the role of BIM as a platform for collabo- ration among client, architects, engineers and future users regarding the conceptual de- sign. Our findings suggest that recurrent reviews of the evolving digital model played a key role in the collaboration. We identified three kinds of design reviews: clash detection, scenario-based reviews and embodied reviews – each focusing on specific aspects of the conceptual design.enText/Conference Paper10.18420/ecscw2017-242510-2591
