NTB Project No. 1008042 Sanitary Sewer Rehabilitation of Sub-Basin 85-211

City of Oakland is soliciting bids for sanitary sewer rehabilitation of Sub-Basin 85-211 under NTB Project No. 1008042, with proposals due October 1, 2026.

The scope comprises approximately 16,805 linear feet of sewer pipe rehabilitation across multiple diameters: 10,217 linear feet of 8-inch, 3,336 linear feet of 10-inch, 1,098 linear feet of 12-inch, and 1,154 linear feet of 15-inch diameter pipe, rehabilitated by pipe-expanding method; plus 541 linear feet of 8-inch to 12-inch diameter pipe rehabilitated by open trench method. Work includes rehabilitation of sewer structures and reconnection and rehabilitation of house sewer connections. Contractors must manage subsurface work involving multiple pipe sizes, multiple rehabilitation methodologies, and coordination of lateral connections throughout the designated sub-basin area.

The City has provided a Hydraulic Modeling Analysis report dated February 13, 2026, as supporting technical documentation establishing baseline hydraulic conditions and post-rehabilitation performance standards. This analysis validates construction methodologies, confirms material specifications, and ensures compliance with City of Oakland standards and applicable California regulatory requirements for sanitary sewer systems. The project specification document (60MB) and HMA report (52MB) are attached to the procurement.

Estimated contract value, contract term, evaluation criteria, and any set-asides or local-vendor preferences are not identified in the available source material.
