2025-2026 Sewer Manhole Rehabilitation Project

The City of Hayward, located in Alameda County, California, is soliciting bids for the 2025-2026 Sewer Manhole Rehabilitation Project, seeking an experienced contractor to rehabilitate 21 aging manhole structures within its sewer collection system. The project encompasses two primary service categories: channelizing (reshaping manhole bottoms for improved wastewater flow) and rehabilitating (applying a mortar and epoxy composite corrosion barrier system lining). Qualified contractors must be licensed in California, possess a minimum of five years of direct sewer manhole rehabilitation experience, and demonstrate successful completion of at least five similar projects within the past two years. The Request for Quotation (RFQ) was released on December 9, 2025, with a question submission deadline of December 15, 2025, and a proposal submission deadline of January 6, 2026, at 4:00 p.m. through the OpenGov Procurement portal. The City anticipates selecting the contractor by February 10, 2026, with work to be completed within 90 calendar days from the Notice to Proceed. Evaluation will be based solely on the lowest total lump sum bid amount that meets specified experience and capacity requirements.

The procurement does not specify explicit set-aside designations or restrictions for disadvantaged enterprises. Contractors must submit a comprehensive bid package including a Non-Collusion Affidavit, Non-Nuclear Weapons Affirmation, and Nondiscriminatory Affirmative Action Certification Statement. The project requires contractors to furnish Performance and Labor and Materials Bonds, each at 110% of the contract price, and comply with prevailing wage requirements under California Labor Code. While specific incumbent vendors are not mentioned, the project involves rehabilitating existing sewer infrastructure primarily consisting of vitrified clay pipe installations from the 1940s-1990s. Liquidated damages are set at $300 per calendar day for delays beyond the 90-day completion window. Though a precise budget is not explicitly stated, the pricing proposal includes five bid items: Mobilization/Demobilization (not to exceed 5% of total bid), Traffic Control, Sewer Bypassing and Flow Control, Manhole Rehabilitation (10 units), and Manhole Channelization (12 units).
