Questions and Answers Updated 7.30.25

Clarification for concrete pad:

The new heat pump unit will be installed in the same location as existing unit. Contractor may choose to use the existing concrete pad, as long as the pad meets the requirements called out in the flag notes. "Pad shall extend 6" beyond the outside dimensions of heat pump." (Sheet 4 of 4 construction drawings).

If the existing pad does not meet this requirement, the contractor will remove and dispose of the existing pad and replace in same location, a new pad meeting the requirements called out in the same flag note for a new pad "New outdoor heat pump to sit on new 6" concrete pad, pad shall extend 6" beyond the outside dimensions of heat pump."

Question 1.

We were unable to open the power panel. Will pictures be taken and posted with the amendment? Please confirm.

Question 12.

Current lead times on equipment show delivery past the period of performance of 60 calendar days. Contingent on issuance of Notice to Proceed. Will the park/contracting work with the contractor to accommodate those lead times?

Government Response:

The Government understands that current lead times on equipment may extend beyond the 60-calendar-day period of performance. The period of performance is contingent upon the issuance of the Notice to Proceed (NTP).

If the contractor provides documentation demonstrating unavoidable manufacturer or supply chain delays, the park/contracting is willing to work collaboratively to assess the situation.

Adjustments may be considered on a case-by-case basis, such as modifying the period of performance or issuing the NTP in alignment with delivery timelines.

However, any adjustments must be formally requested in writing, justified, and approved prior to issuance of the NTP.
