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 No. WW-719B) 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 (this Contract)
• WW-719C Folsom Area Stormwater Improvements – Harrison/Treat Box Sewers and Connecting Auxiliary Sewers
• WW-719D Folsom Area Stormwater Improvements – Western SOMA and Northern Mission District Sewer Replacement
Contract No. WW-719B will address the SSIP’s LOS in the City’s Inner Mission District. The proposed improvements under Contract No. WW-719B include:
• Building a new wet weather sewer tunnel;
• Constructing two access structures;
• Modifying the foundations of existing Caltrans’ US-101 (Central Viaduct) bridge structure;
• Replacing an existing portion of the Division Street Box Sewers; and
