Project Description

The San Francisco Public Utilities Commission (SFPUC) is issuing this Request for Qualifications (RFQ) in search of candidates with the specified qualifications to respond to the forthcoming Request For Bids (RFB) to construct the WW-719CR Folsom Area Stormwater Improvements –(FASI) Harrison/Treat Box Sewers and Connecting Auxiliary Sewers (Project). A “Candidate” is any entity responding to this RFQ.

The SFPUC Wastewater Enterprise is proposing the Project to address the Sewer System Improvement Program’s (SSIP) level of service (LOS) in the City’s Inner Mission District. The goal is to control and manage flows from a statistically derived, LOS-design storm of 3-hour duration and delivering 1.3 inches of rain. Properties have been subjected to stormwater inundation during moderate-to-heavy storms. The lower-lying areas can experience up to several feet of flooding.

This Contract (Contract WW-719CR) is part of the larger Folsom Area Stormwater Improvements Project (FASIP). FASIP consists of four construction contracts (including this Contract). The construction contracts are:

• WW-719A Folsom Area Stormwater Improvements – SOMA and Mission Districts Sewer Replacement
• WW-719B Folsom Area Stormwater Improvements – Alameda Street Wet Weather Conveyance Tunnel
• WW-719CR Folsom Area Stormwater Improvements – Harrison/Treat Box Sewers and Connecting Auxiliary Sewers (this Contract)
• WW-719D Folsom Area Stormwater Improvements – Western SOMA and Northern Mission District Sewer Replacement

Contract WW-719CR will address the SSSIP’s LOS in the City’s Inner Mission District. The proposed improvements under WW-719CR include:
• Building a new box sewer on Harrison Street to collect all-weather flows;
• Replacing the existing box sewers on Treat Avenue (used for only wet-weather flows);
• Building a new box sewer on Florida Street to collect wet-weather flows;
• Installing a new auxiliary box sewer on 17th and 18th Streets;
• Lining existing sewers on 18th Street;
• Relocating existing sewers; and
• Building and/or modifying existing junction structures.

The SFPUC strongly encourages all Candidates to attend the RFQ Pre-Submittal Conference on: October 15, 2024, 10:00 am – 11:00 am.
