Description

The City seeks a contractor to complete the design, engineering, equipment procurement, permitting, utility coordination, installation, and commissioning of a grid-tied, net-metered rooftop solar PV system. The system must provide at least 115 kW DC of PV module capacity and no more than 100 kW AC of inverter output. Work includes an independent structural assessment of the roof, final stamped design documents, required electrical upgrades and interconnection approvals, monitoring equipment, and coordination to preserve the roof warranty and minimize disruption to facility operations. The proposal must include a cover letter, qualifications and experience (including at least two public-entity references and descriptions and photos of at least two similar completed projects), a detailed work plan, equipment specification sheets and warranty information, a detailed project budget with a 5% contingency, a project schedule, and a statement regarding acceptance of or requested changes to the sample contract. The selected contractor must meet prevailing-wage requirements, provide the specified system warranties, and place the system in service by December 1, 2027 to support the City's elective-pay tax-credit plans. The sample contract also requires payment and performance bonds after selection; these are not proposal-stage submissions.
