Description

The City of Redding is soliciting bids for the complete replacement of the Burney Library roof, installation of a 26‑module photovoltaic solar array, and addition of a standby diesel generator with associated fuel and control systems. The scope includes demolition of existing roof components, structural concrete work for a generator foundation, full roofing system (composite shingle roof, metal trim, roof heat tape, ridge vent), electrical distribution upgrades, PV racking, inverter, panelboard, conduit, and an automatic transfer switch. The contract is a fixed‑price, lump‑sum public‑works bid with a base schedule of 50 working days (≈ 10 weeks) and up to 75 working days if all optional alternates are funded. Key compliance requirements include a water‑pollution control plan, special inspections for concrete, PG&E interconnection approval for the solar system, and extensive bonding and insurance obligations.

Budget estimate

$250,000 – $600,000

The engineer’s estimate lists a base bid of $265,000, while the compiled bid tabulation shows total bids ranging from $265,100 up to $602,559 (including all optional alternates). Assuming the winning contractor will be paid near the lower end of that range for the base scope plus a modest amount for any funded alternates, a reasonable estimate is between $250,000 and $600,000. Factors influencing the final amount include the selection of the lowest‑bidder, whether additive alternates are funded, and any change orders during construction.
