Replace Roof Surfaces 140P4526R0034

1. We are including 50% selective roof decking replacement in our bid. Can a similar quantifiable percentage be given for the selective replacement of eave / rake fascia and soffit repairs?

Please include an allowance for 25% selective replacement of the existing eave and rake fascia and soffit materials. Any replacement beyond this quantity should be handled through established unit pricing and approved by the Contracting Officer before proceeding.

2. Will the Dingman School and Jackson House receive the same new roof as each other?

Yes. The Dingmans School and Jackson House should receive the same general roofing system: a flat, slate-profile concrete roof tile with an integral color suitable for freeze-thaw conditions. The final profile and color should be compatible with each building’s historic character and approved through the submittal process.

3. What is the desired thickness and exposure of each slate tile?

The roof tile should have a nominal thickness of approximately 1/2 inch. The dimensions may vary by manufacturer, the exposure should follow the approved manufacturer’s installation requirements, with a minimum 3-inch head lap. For a typical 17-inch tile, the installed exposure will generally be approximately 13 to 14 inches. The contractor should submit product data, dimensions, exposure, weight, and installation details for approval before ordering.

4. Site visit: The solicitation identifies a September 1 site visit. Was attendance at that visit a mandatory condition for proposal eligibility, or may an otherwise qualified offeror that did not attend still submit a proposal?

No attendance was not mandatory

5. Decking/sheathing: The SOW states selective roof decking/sheathing replacement may be required up to 50% at the two locations, while the price schedule uses lump-sum line items. Should offerors include the full potential 50% replacement in the lump-sum price, or price based on an assumed quantity with actual replacement handled separately if conditions differ?

Offers should price based on an assumed quantity separately not in lump sum
