NIGP 70058: Proofing Systems

NIGP 70058 Proofing Systems, an Item code, encompasses roof replacement and repair work on public buildings and facilities, as demonstrated by recent municipal solicitations seeking qualified contractors to execute full roof replacements with compliance requirements spanning building code adherence, historic preservation, and archaeological protocols. State and local governments buying under this code procure services including removal and replacement of roofing materials, repair or replacement of roof sheathing, installation of underlayment and shingles, gutter and downspout work, and related waterproofing measures on existing structures. Issuing bodies include city engineering departments and municipal facilities management offices; the activity shown here involves a city government with local-vendor preference scoring.

The City of Madison issued RFB# 15026-0-2026 for Normal Hall Roof Replacement in Madison, Wisconsin on July 10, 2026, with bids due August 6, 2026 at 2:00 PM CST and a mandatory pre-bid site visit on July 22, 2026. The scope covers approximately 3,600 square feet of asphalt shingle roof replacement on a historic park pavilion, including removal of existing materials to sheathing, sheathing repair, installation of new underlayment and shingles, counterflashing replacement, and reinstatement of gutters and downspouts. Work must begin on or about October 1, 2026 and complete by October 30, 2026 under a fixed not-to-exceed cost structure. The project triggers Wisconsin burial-site preservation requirements and mandates metal-detector sweeping within 100 feet of the building, detailed photographic and as-built documentation, one-year warranty coverage, and Commercial General Liability insurance of at least $1,000,000 per occurrence. Local vendors registered with the City of Madison receive a scoring preference. Questions deadline was July 28, 2026, with answers posted by July 31, 2026.
