Repair Welded Steel Roof Whitlock North 5MG Tank

Pueblo Water (Board of Water Works of Pueblo, Colorado) is requesting qualifications for contractor teams to design and construct repairs to the roof of the Whitlock North 5MG potable water storage tank, with RFQ submissions due November 3, 2026 at 2:00 p.m., followed by a mandatory pre-proposal inspection on November 17, 2026 and proposals due December 4, 2026.

The scope encompasses removal of the existing roof structure and steel plate panels; reinforcement and modification of the tank shell to accommodate an AWWA D108 aluminum geodesic roof system; design and installation of the aluminum geodesic dome; repair of foundation ringwall cracks and spalling; installation of chime joint protection systems; floor plate repair; replacement of access systems; and repair of interior and exterior coating systems. The 180-foot-diameter, 27.25-foot-wall tank was originally constructed in 1975, underwent interior refurbishment in 2004, and failed 2026 inspection due to multiple fallen roof rafters and significant roof corrosion. Matrix Design Group will provide all design elements, including sealed and stamped construction plans, structural analysis, stability calculations, and shell stiffening design. Contractor teams must be professionally licensed, bonded, and insured; demonstrate surety-bond capacity of $1 million; and submit 2024–2025 financial statements. Liability insurance must include workers' compensation, commercial general liability, and professional liability.

Evaluation emphasizes team strength and capacity (20 points), team competence and experience (25 points), and project profiles (55 points), with preference for demonstrated potable water welded steel tank construction experience, geodesic dome installation experience, and qualified key team members. Pueblo Water will identify short-listed respondents by November 6, 2026. Short-listed teams may not make significant changes to team composition or personnel without written approval. The anticipated award date is December 16, 2026. The project site is located at the Whitlock Treating Plant in Ouray County, Colorado.
