The construction industry has experienced many inspiring improvements. Especially two movements have introduced innovative design and construction practices: The advancement of lean thinking and tools and maturity in applying BIM and related concepts and technologies. Although Lean and BIM often thrive in the same culture, have many similar properties and strong potential synergies, they are often considered separate initiatives and unfortunately provide only partial benefits when applied on their own. Based on empirical findings of a general contractor, this paper shows how collaborative lean methods and BIM-related technologies can be implemented in an integrated way in practice.
