abstract={There are multiple studies emphasising the positive interaction between Lean Construction and BIM use. Nevertheless, it is often difficult to find a direct link between this integrated strategy and the project outcome. This paper presents a case study of a large hospital project in a dense downtown environment, where BIM and Lean were used in synergy - mutually informing each other and catalysing their impact. This project created opportunities for multiple innovations and optimisations. This paper will focus on the positive impact from simultaneously applying 4D-BIM and a variation of takt-time planning to the demolition of the old hospital building adjacent to the new one. The optimization between the demolition and the new construction was crucial for the project, as it allowed the Design-Builder’s company to shorten the schedule by two months and to win the contract. Another innovation was the automated update between master schedule, takt-time plan, BIM model, and project documents (including 2D plans and Virtual Reality). This automated loop makes the schedule available to each construction stakeholder (from client and designers, to the foremen) in the format that is most appropriate and useful for them. It also allows for easy progress tracking and control.  },
