7/31/2020 22

The Statement of Work states we are to provide all equipment and labor shown in the drawings and specifications titled “Energy: Upgrade HVAC and DDC Systems Base Wide”. The plans with this title show work at six total buildings. The ES2 drawings that were included in the solicitation shows HVAC controls work at 21 buildings.

Please advise if this project is to include the controls work at all 21 buildings. If so will there be electrical and mechanical drawings issued for the non-controls related work needed at these buildings? It is our understanding the controls contractor will need electrical and mechanical contractors assistance in completing their work but this is not called out on any drawings. If drawings will not be issued can we get a scope of work detailing what additional electrical and mechanical work is needed at each building?

Yes, the contractor will be responsible for the controls for all 21 buildings the plan set for controls was left out of the SOW in error. The plan sets and specifications to be bid are listed in the solicitation. The controls system needs to be fully functional at the completion of work. If additional electrical and mechanical work is necessary it must be covered by the contractor to ensure controls shown in the controls shop drawings are fully functional after work is complete. Pre-bid there will not be any additional plans issued for the buildings where only controls are being installed.

Also, please see DFARS 252.236-7001 as contained in the solicitation.
