Offerors should disregard this phrase. SOW item 5 and 8 refer to replacement of approximately 275 feet of line sets from the branch box to the condenser, however it does not seem to mention replacement of the piping from the branch box to each evaporator (of which there are 7 listed in the scope.

No. Please confirm if tax should be included in our proposal? Will an exempt certificate be provided?

Standalone controls for each head, no BMS. Please provide electronic copies of the floor plans handed out during the site visit. Unsure of what floor plans are being referred to. Are as-builts available showing the existing piping routing? Not available. Will unforeseen conditions be addressed via the changed clause per VAAR 852.243-70 or FAR 52.243-4? #5 on page 4 indicates approximately No. Because this requirement is being solicited as a commercial services contract under FAR Part 12, neither VAAR 852.243 70 (Construction Contract Changes) nor FAR 52.243 4 (Changes Construction) applies. FAR 52.212 4(c) (Changes) governs permissible changes to commercial contracts. Any modification must be within scope and mutually agreed to by both parties. Equitable adjustments related to unforeseen conditions may be addressed only through a bilateral modification, since unilateral change authority does not apply to commercial services unless explicitly stated.
