Regional Sewer Pipeline Project

The City of Wheatland, California is soliciting bids for the construction of a 7.7-mile regional sewer pipeline to transport raw wastewater to the OPUD service boundary, along with the construction of two new pump stations and upgrades to existing lift stations. Work includes trenching, horizontal directional drilling, and jack and bore methods for pipeline installation, demolition and replacement of an existing pump station, construction of a new well booster pump station, installation of electrical and control systems, culvert replacement, site restoration, and comprehensive startup and testing. The project is governed by industry standards including NEC, NFPA, IEEE, OSHA, ANSI, ISA, and UL, with materials and equipment required to meet specified durability and environmental resistance standards such as MIL-STD-810C for plastic pipe markers. All work must comply with California Building Code and other referenced technical specifications, with inspections conducted at both manufacturer facilities and the project site, culminating in final acceptance by the Engineer or Owner’s Inspector. The contract follows a Lowest Price Technically Acceptable procurement model, where awards are made to the lowest responsible and responsive bidder among those who meet all mandatory requirements for financial capability, equipment, personnel, record of successful project completions without liquidated damages or excess claims, legal eligibility, and full compliance with contract documents. No cost trade-offs or scoring weights are applied; technical acceptability is a threshold condition, and price is the sole differentiator. The only confirmed monetary value in the bid schedule is a $175,000 allowance for dewatering under Schedule A, with all other line items listed as lump sum without established pricing, and additive alternatives provided without cost figures, making the total contract value indeterminate based on available data. Proposals must be submitted electronically via the designated bidding website by the deadline of August 25, 2026, organized into six bound volumes covering contract requirements, specifications, and drawings. Contractors must ensure compliance with safety regulations, equal opportunity flow-down provisions in subcontracts, and make all records and personnel available for inspection. Packaging and marking requirements enforce strict protections against damage and corrosion, with precise labeling standards for equipment, tools, and materials, including indelible markings and standardized danger signs. No federal accounting codes, electronic invoicing systems, or designated contracting officer representatives are specified, and no completed certifications or socioeconomic disclosures are provided in the solicitation.
