Conference paper
It is not easy to evaluate Building Information Modelling (BIM) and Lean Construction (Lean) capabilities of design firms. The paper investigates the level of BIM and Lean implementation at representative design firms in Massachusetts. A survey was given to the principal design firms working for a large public client. First, answers were analysed and discussed. Second, results from the same design firm were compared to detect possible inconsistencies. Main results show that there is still not a clear definition of BIM and Lean; BIM training is not done consistently within design firms; and there is not a common understanding of BIM and Lean within each design firm, even though most designers affirmed that they have internal standards. Results of the survey could be useful for designers to develop internal standards and establish training courses for the design firm and clients to better understand designers' approach to BIM and Lean.
