Sewer Main Replacement Project on Sierra Vista Avenue

City of Alhambra is requesting sealed bids for sewer main replacement on Sierra Vista Avenue (Project No. N2M26-94), with bids due November 5, 2026 at 10:30 a.m. and public opening at 11:00 a.m. in City Council Chambers. This is a public works project subject to California prevailing wage requirements and DIR registration.

The scope includes removal of seven existing manholes, construction of four new manholes, and replacement of approximately 1,100 linear feet of sewer main along Sierra Vista Avenue from San Marino Avenue to Los Higos Street. The project will replace the existing 8-inch Vitrified Clay Pipe (VCP) sewer with 10-inch VCP sewer at the same line and grade to address hydraulic capacity deficiencies and provide adequate capacity for ultimate flows per the City's Sewer Master Plan. The construction duration is 120 calendar days from the effective date of the Notice to Proceed.

Bidders must hold current California contractor licenses and City business licenses. As of March 1, 2015, contractors must be registered with the California Department of Industrial Relations (DIR) to bid or serve as subcontractors on public works projects. Prevailing wage rates established by the State Director of Industrial Relations apply. Bids must be accompanied by a bid bond equal to no less than 10 percent of the bid amount and submitted on approved Proposal forms. The City will deduct 5 percent retention from all progress payments. For bid evaluation, the City will reduce qualifying bid amounts by 1 percent if sales or use tax refunds are applicable, though actual payment will not reflect this reduction. The City reserves the right to reject any or all bids and hold bids under advisement for 60 calendar days.

Pre-bid inquiries in written form are due by 4:00 p.m. on October 22, 2026. Plans and specifications are available electronically from Kip Su, Engineering Associate – Utilities, at ksu@cityofalhambra.org or 626-570-3228.
