<p>Construction scheduling is one of the key processes during the development of construction
projects. As Building Information Models (BIM) gain more and more in importance for the design
process, the scheduling process also has to be integrated into the collaborative model based working
environment. For this purpose a Business Process Re-engineering approach (BPR) was applied to
identify potential areas of improvement within the current scheduling and 4D simulation practice.
This paper highlights the main findings and describes a novel solution approach consisting of a
dynamic collaboration framework tailored for construction scheduling. Several tools were
implemented to prove the new concept. The Industry Foundation Classes (IFC) are deployed to
ensure open communication within the project team. Further research is ongoing within the
European R&D project InPro.</p>
