Replace Existing Roof at the Visitor Center and Tribal Offices Questions, RFI Due August 31, 2026 3:00 PM MST

Reference: Project Specifications Section 01 11 00, Summary of Work, pages 01 11 00-2 through 01 11 00-3; Section 01 27 00, CLIN 01 – Demolition; Drawing A1.

The specifications require repair of the roof deck as required, while the Safety Requirements also identify the potential for concealed deteriorated wood decking or structural components discovered during demolition. Since the existing roof deck will not be fully visible until tear-off, please confirm how deterioration beyond the specifically depicted missing or disturbed areas should be priced.

Should offerors include an allowance or assumed quantity of deck replacement in the lump-sum bid, or will concealed deterioration discovered after demolition be handled as a differing/unforeseen condition and contract modification? Roof deck repair is limited to areas where existing roof penetrations are demolished and infill of the roof decking is required to match existing conditions.

The Safety Requirements identify deteriorated wood decking as a potential condition that may be encountered during construction; however, based on available information and knowledge of the existing conditions, deterioration of the existing roof decking is not anticipated.

If deteriorated or otherwise unsound roof decking is discovered during demolition, notify the Government prior to proceeding with repairs. Such conditions will be evaluated and addressed as an unforeseen/differing site condition, as applicable.
