NIGP 09064: Proof Boxes

NIGP 09064 Proof Boxes, an Item code, captures roofing materials and components that state and local governments procure for building envelope repairs and replacements — though recent solicitation activity under this code reflects broader roof restoration work including material supply, structural repairs, and installation labor. The City of Madison Engineering's Normal Hall roof replacement represents the kind of work being solicited: removal and replacement of existing roofing systems, repair or replacement of damaged structural components, installation of new underlayment and finished roofing materials, and restoration of ancillary systems such as gutters and downspouts. Issuing bodies soliciting under this code include city engineering departments and municipal procurement offices managing capital maintenance for municipal buildings and parks.

The City of Madison RFB# 15026-0-2026, posted July 10, 2026 with bids due August 14, 2026, solicits replacement of a 3,600 square-foot asphalt shingle roof on a historic park pavilion, including sheathing repair, new underlayment and asphalt shingle installation, and counterflashing replacement at clerestory windows. Work must be completed by October 30, 2026. The solicitation carries a local-vendor preference for vendors registered with the City of Madison as of the bid due date, requires a mandatory pre-bid site visit, and imposes compliance with Wisconsin burial-site preservation statutes due to the building's location on a designated American Indian burial area. Contractors must provide Commercial General Liability insurance of at least $1,000,000 per occurrence and maintain daily photographic documentation of work progress. Recent opportunity activity is concentrated in Wisconsin municipalities.
