Questions & Answers / Clarifications

This document contains questions submitted by potential bidders and the government's responses, clarifying various aspects of the solicitation.

• Base Bid Scope: The Base Bid exclusively includes air infiltration and shaft sealing work. Curtain wall replacement will NOT be included in the award or evaluated as optional work. The project will ONLY consist of the base bid.
• Bid Options: No bid options are being considered or evaluated; the contract award will be based on the Base Bid only.
• Scope Narrative: A detailed scope narrative for the Base Bid is provided, outlining work for sealing intake housing, pedestrian doors, basement coiling doors, utility air shafts, and penetrations. Review of drawings and specifications is required for specific details.

• Door Identification: Specific doors included in the perimeter door gasketing work are identified on the drawings.
• Coiling Doors: Specifications for insulated, airtight coiling doors are referenced in the specifications. Existing electrical service is to be reused for new motorized doors.
