Replacement of Various Roofs at Wastewater Reclamation Facility

The contract entails the complete removal and replacement of multiple ballasted roofs at the City of Pueblo Wastewater Reclamation Facility in Colorado, addressing urgent infrastructure needs due to the existing roofs being over 15 years old, failing at the edges, and exhibiting numerous leaks including around skylights, precluding repair. The scope covers various facility buildings—including administration, shop, secondary clarifier, non-potable water, and D.A.F. structures—with detailed work encompassing demolition of existing roofing systems, installation of new roof decking, rough carpentry, insulation (specifically polyisocyanurate rigid boards), cover boards, and the application of a built-up bituminous roofing system with aggregate surfacing. The roofing materials and installation must meet rigorous industry standards such as ASTM, UL, FM 4470 for wind uplift resistance (minimum 130 mph), Class A fire ratings per ASTM E-108, and the 2021 International Building Code. Quality assurance includes manufacturer-certified installers, material certifications, detailed submittal of product data, shop drawings, and sample mock-ups. Warranty provisions require a minimum 25-year coverage with a 30-year no-dollar-limit wind uplift warranty, and manufacturer inspections will verify installation conformity. Contractors responding to this low price technically acceptable (LPTA) solicitation must comply with numerous administrative requirements including compliance with applicable labor standards under the Davis-Bacon Act with wage determinations specified for Colorado, federal labor provisions, and local licensing and taxation rules requiring contractor registration and city sales tax prepayments for contracts over $100,000. The solicitation, issued by the City of Pueblo in December 2025, establishes key dates such as a mandatory pre-bid meeting, question deadlines, and a bid submission deadline via the OpenGov electronic portal. Bidders must provide required documentation including bid guarantees, affirmative action plans, insurance certifications, environmental compliance, and commitment reporting for Disadvantaged Business Enterprise (DBE) participation and Section 3 requirements to promote opportunities for low-income persons. Payment terms, contract execution, and performance bonds follow City of Pueblo standard contracting procedures. The contract requires contractors to maintain specified storage, handling, and preservation of materials with prohibitions on polyethylene coverings for insulation and mandates proper labeling of all materials to ensure traceability. Inspection and final acceptance will be conducted on-site by the City Engineer, who retains sole authority to approve or reject work. The overall performance period is defined in the bid with work commencing within three days of notice and completion expected within a bidder-defined timeframe.
