Q: This project presents a great opportunity to replace the roof at the Denver Site (and will also help reduce the weight load and need for structural upgrades). Will the government entertain proposals that include a roof replacement? Will the additional cost be weighed in a “best value” evaluation, rather than “lowest cost”?

A: Yes, roof replacement proposals will be considered. There is no longer a warranty on the existing roof. UFC 3-110-03, 01 May 2012, Change 2, 1 Jan 2017, UNIFIED FACILITIES CRITERIA (UFC), ROOFING is included with amendment documents for your information.

Q: The current administration is reviewing the implementation of a new solar tariff in January.

There is a potential that this could impact our costs/pricing. When does the government anticipate contract award/notice to proceed?

A: Within 90 days of award.

Q: Can we tie into the existing perimeter security fence, or does a new fence need to be built around the entire ground mount array? If we cannot tie into the existing fence, please provide an acceptable separation/distance that must be maintained between the security fence and array fence.

A: The existing fence may be used as one side of the enclosure. No structural or physical changes may be made to the existing fence.

Q: Do the installations have a requirement for hydro-excavation at both sites?

A: No.

Q: At both sites, there appears to be little space in the electrical rooms for additional equipment.

Would the government entertain proposals to mount equipment on the exterior wall and secure it with fencing at both sites?

A: This is a design/build contract. Include equipment locations in proposals.

Q: As these locations are both on Federal property, please confirm we will NOT be required to pull any permits with the city.

A: No city permits are required.

Q: At the site visit (and a review from an engineer), the roof at the Denver site appears to be maxed out for weight loads for the existing structure. Will we be required to retrofit the existing trusses or building to accept the additional weight of the new PV system? If this is the contractor’s responsibility, please specify what structural/roof submittals will be required with the proposal.

A: If the proposal includes structural reinforcement of the roof, full structural plans and details describing the work are required. Roof submittal should include, at a minimum, roofing system materials, details and warranty information.

Q: Will the government accept emailed (electronic) proposals?

A: Yes.
