Project Plan: Construction Delivery Method: EPC (Engineer Procure Construct) The weight of the HVAC units and LEF-1 central exhaust unit increased dramatically from 30% design level to IFC. Ultimately some additional steel reinforcing was required for supporting LEF-1 fans. This added cost to the project.
Evaluate with the steel fabricator how the structural engineer has designed the connections. It may save time on installation to change details calling for welds to all bolted and accelerate schedule/save on labor.
