You will soon notice the elevation of soil lowering on the PRAB site as shoring operations move from along Koret Way to Parnassus Avenue. For shoring, workers are drilling to install piles in the ground for the retaining wall. The piles are vertical steel beams encased in concrete. As the retaining wall is finished, excess dirt will be removed to create space for the building. 

• There will be some noise from the excavator, soil drill rig and concrete trucks.  
• You can expect to see large trucks and equipment on the site.   

Koret Way is open to pedestrians and will remain open through 2024. Construction flaggers will be present to control pedestrian traffic during deliveries as a safety measure. Any long-term Koret Way closures will be communicated widely to the Parnassus Heights campus. 

Koret Way remains closed to vehicle traffic and parking. ADA parking and some state vehicle parking is still available in the Koret Way Surface Lot near the School of Nursing building.    

• Pedestrians can access Koret Way; construction flaggers will be present to control pedestrian traffic during deliveries as a safety measure.  
• ADA parking will still be available.  
• Deliveries will be able to access Koret Way.  
• Traffic flaggers will direct pedestrian and vehicle traffic.  
• No drop-offs, pick-ups or drive through traffic will be allowed on Koret Way.  
• Emergency access is open from the School of Nursing building to Koret Vision Center.  
• Employees may park in the ACC Garage. For additional parking options, visit: campuslifeserviceshome.ucsf.edu/transportation/parking-locations-PH.

Plans are underway to install new utilities along the PRAB Promenade and Koret Way. The mechanical, electrical, and plumbing utilities serving PRAB will begin installation this summer and the work in Koret Way is expected to be complete by the fall. Some existing utilities will also be demolished. 

• Expect noise near the construction area during the demolishing of utility lines. This work may impact building occupants near the PRAB site. 
• Possibly slight alignment changes to the pedestrian path of travel on upper Koret Way.

In late April 2024, construction is expected to be complete on the lower level on the west side of the Clinical Sciences Building (CSB). The project is to build a temporary wall to protect CSB during PRAB construction, where CSB and UC Hall had previously been connected. Currently, waterproofing the wall is underway, with minimal impacts to building occupants. Tiebacks, or horizontal rods, will extend below CSB. These tiebacks will help stabilize the retaining wall for PRAB.     

• CSB occupants can expect to hear some noise and vibrations during this work.  
• A boom lift will be on the exterior northwest corner of CSB.  
• Pedestrians on Parnassus Avenue will be rerouted around the construction activities. 

During PRAB construction, pedestrian pick-ups and drop-offs for the UCSF Dental Center should go to the south entrance in the Kirkham Lot (not Parnassus Avenue). This reroute is to support the flow of pedestrian and vehicle traffic and safety near the construction site.

Also, expect noise near the PRAB construction site from demolition and other work. To limit noise, an excavator will be using concrete shear attachments. See map for best route.

UC San Francisco has received approval to move forward with a new research and academic building at Parnassus Heights, creating a vital collaborative space to drive innovations in scientific research and education.

The UC Board of Regents voted Sept. 20, 2023 to approve the exterior design, as well as the project scope, environmental review, and $842 million budget for the building, which is expected to create hundreds of jobs during its construction. Half of the funding is expected to come through external financing and half from philanthropic gifts.
