Summary
The committee recommended approval of a $19.5 million amendment to the SFPUC headworks planning and engineering contract, increasing the contract to $33.5M and extending its term to support expanded design and construction‑phase services for the Southeast Plant replacement.
The Budget & Finance Committee recommended approval of a resolution to amend the planning and engineering agreement for the Southeast Plant headworks replacement on Nov. 30, increasing the contract by $19.5 million to a not‑to‑exceed $33.5 million and extending the term through late 2020.
Karen Kubik, director of the source system improvement program for the San Francisco Public Utilities Commission (SFPUC), said the city’s Southeast Plant — a 70‑year‑old facility that treats about 80% of the city’s wastewater flow — faces unusually high grit loads, seismic vulnerability and odor‑control deficiencies. Kubik said design work and coordination with several concurrent plant projects revealed additional necessary scope and construction‑phase design support. The headworks had a previously identified baseline budget of $385M in a $2.9B Phase 1 portfolio of the SIRS program; the contract amendment is intended to cover expanded detailed design, grit screening, odor control and construction coordination work.
Severin Campbell, representing the Budget Legislative Analyst, noted expenditures to date of $6.4 million on the contract, reported the headworks project budget increased from about $184.9M to $358.6M based on refined scope, and said design was expected to be 100% complete by May 2018. BLA recommended approval.
Supervisor Tang moved to forward the resolution with a positive recommendation; the motion was seconded and taken without objection.
