In total, 40 issues were identified during visual coordination and 180 during automated clash detection. Most of the issues were replicated across the building, and one group could include hundreds of similar clash instances across the building, for example, pipe clashes in the same model.
A simple estimate shows that dealing with these issues on-site costs a significant amount of money. The assumption was made that one issue can be resolved by 2 people in 2 days. In total it results in 7104 h spent. With an hourly rate of 20 EUR solving these issues would cost more than 140k EUR.

The Pilot proceeds with an as-built model development. More conclusions will be made and we will write about them. Leave a note if you want to hear about the second phase.
ITED's team was responsible for the project management, MEP model development and 5D scheduling in for this project.
