A qualified licensed paint contractor or abatement company must perform lead paint removal and new coating.

Bidders must demonstrate a minimum of five years of similar experience and successful completion of at least three comparable projects within the past five years. Pricing must be submitted as a not-to-exceed total cost with itemized line items for sandblasting protection, coating systems labor and materials, roof demolition and disposal, metal roofing installation labor and materials, and stamped structural engineering. Insurance requirements include $1 million commercial general liability per occurrence, $1 million owner's protective liability, builders' risk at 100 percent replacement value, and $3 million commercial umbrella/excess liability. A two-year warranty on workmanship and manufacturer warranties are required. Expected completion is no later than 14 days after contract execution, with $300 per day delay penalties for work exceeding 60 calendar days. Pre-bid questions are due September 23, 2026 at 1:00 p.m. All submissions must be uploaded electronically to MITN with a 20 MB file size limit; hard copies are not accepted.
