Approve Increase to the Construction Duration Contingency for Contract No. WD-2895, San Francisco Zoo Recycled Water
Summary of Proposed
Commission Action:
Approve an increase of 203 calendar days (approximately seven months) to the duration contingency for Contract No. WD-2895, San Francisco Zoo Recycled Water, with Basset Engineering, for a revised duration limit of 670 consecutive calendar days (approximately one year and 10 months), with no change to the contract amount, to allow for the completion of the project which is delayed due to the additional time required for manufacturing and procurement of long-lead electrical equipment.
Background: The San Francisco Public Utilities Commission (SFPUC) is building a recycled water facility to serve the San Francisco Zoo (Zoo) and the lower Great Highway to support water conservation efforts. The Zoo currently relies on groundwater pumped from the Westside Groundwater Basin to supply various non- potable demands such as landscape irrigation, animal exhibit washdown, and impoundment and animal pool filling. The Lower Great Highway also relies on this groundwater for landscape irrigation.
The San Francisco Zoo Recycled Water Project (Project) is a new recycled water pipeline in the public right-of- way to the groundwater reservoir and pump station facility (owned and operated by San Francisco Recreation and Parks Department) to convert the Lower Great Highway’s and Zoo’s current groundwater supply to recycled water supply from the SFPUC ) Westside Recycled Water Treatment Facility, except for end uses that require potable water (such as drinking water for animals). Supplying these demands with recycled water will offset close to 100% of the Lower Great Highway’s and Zoo’s annual groundwater use and will conserve high quality groundwater to supplement potable water supplies in San Francisco. Approximately 200,000 gallons of groundwater each day will be offset by recycled water through this Project.
On February 13, 2024, by Resolution No. 24-0027, the Commission awarded Contract No. WD-2895, San Francisco Zoo Recycled Water to Basset Engineering, in the amount of $2,175,723 and with a duration of 425 consecutive calendar days.
Scope of Contract: The contract work location is in the City and County of San Francisco on Sloat Boulevard, West of Skyline Boulevard. The contract work includes Agenda Title: WD-2895, San Francisco Zoo Recycled Water Commission Meeting Date: June 10, 2025
installation of:
