About this file
This is Addendum #01 to a Request for Bids (RFB-DMAVS-2027-03) issued by the State of New Hampshire Department of Military Affairs and Veterans Services for Center Strafford Site MEP Upgrades. The addendum modifies the roofing specifications in Drawing A-1.2, specifically revising General Roofing Note "E" at Alternates 1, 2, and 3. The key change requires contractors to provide roof curb adapters at existing roof penetrations to install new Energy Recovery Ventilation (ERV) units, with shop drawings submitted to the architect and owner for approval during the submittal process. If the new height of the mechanical units is deemed unacceptable, existing mechanical roof curbs will be replaced by change order. The bid closing date is September 2, 2026 at 12:00 PM. This addendum supersedes previously submitted documents and must be included with all bid submissions.
The addendum specifies that the existing roofing system is a fully adhered TPO (thermoplastic polyolefin) system manufactured by GenFlex Roofing System, LLC, with roofing work performed by Skyline Roofing Company of Manchester, New Hampshire. At all membrane roofs, wood blocking and nailers should be provided as pressure-treated only if required to maintain warranty of the existing membrane manufacturer. Bidders must acknowledge receipt of this addendum and submit it with their bid proposals, with complete bid documents and all addendums available through the New Hampshire Department of Administrative Services purchasing website.
