Utility routing — both above-ground and trench-based — also continues in the project site area near the SON Building to support future campus infrastructure connections.

The installation of new chilled water piping from a utility yard, known as the Hooper Pad, to HSW (see the red line below) will require multiple chilled water shutdowns. The shutdowns, which are scheduled to start: 4 a.m. January 24, 2026, through 12 a.m. January 25, 2026, and will impact the Clinical Sciences Building (CSB), Health Sciences East and West (HSE and HSW), the Medical Sciences Building (MSB), and the Ray and Dagmar Dolby Regeneration Medicine Building.

A second chilled water shutdown will impact HSW only at a later date. 

The chilled water shutdowns will not affect domestic water (restrooms, sinks, drinking water). Facilities Services shutdown notices will be distributed to impacted buildings.

The new Ladle & Leaf location in Millberry Union, room 135, 500 Parnassus Ave., is now open to the Parnassus Heights community and beyond. Construction for the relocated café reached substantial completion in late November, followed by final inspections and operational setup. The cafe officially opened on December 17, 2025.

The relocation from the former School of Nursing building supports the Parnassus Commons (PCCSI) project and the broader campus revitalization effort. The refreshed space offers indoor seating and an outdoor terrace and is designed to function as a community lounge outside of café hours, accessible with a UCSF ID badge.
