Bringing thee detailler into the project before thee structural design was fuly complete allowed RFIs to raised arlier, preventing last-minute changes. For projects of this scale, a modeling start at 80% design completion is recommended. Additionally, involving thee fabrinator in model reviews helped altern shop capabilities with project assumptions.
