Protective debris netting is being installed along Medical Center Way and will remain in place through approximately 2028 as vertical construction of the new hospital progresses. In preparation for the structure rising, the project team will conduct a load test of the safety netting system on March 21, 2026. During this test, a worker suspended in a steel basket from one of the project’s tower cranes will drop weighted materials onto the netting to ensure it meets required performance standards. This specialized safety test has been conducted only a limited number of times in the United States.

• March 2026: Structural steel deliveries expected to begin with flaggers in place to support safe traffic flow.
• Protective debris netting installation underway along Medical Center Way and near the existing hospital loading dock; netting expected to remain in place during the building’s steel erection through 2028. Testing of the netting is scheduled for March 21, 2026.
• Weekend closures of Medical Center Way will continue; weekday single-lane conditions may occur periodically.  
• Construction hours for this project include "noisy" work from 8 a.m. to 5 p.m. Monday through Friday, and 9 a.m. to 4 p.m. on Saturdays.  
• Dates and details are subject to change. 

Now – December 2026: A partial renovation of the Clinical Sciences Building (CSB) is scheduled on the west and north sides of level 7, where the building connects to BRAB. The new space will accommodate future research activity and program connectivity between the two buildings. A bridge from CSB to BRAB is also under construction.

Now – June 15, 2026: CSB occupants on floors 5-7 can expect intermittent noise and vibration during window removal and installation on levels 6 and 7. This date was extended due to unforeseen site conditions. The UCSF community can find additional information in this Construction Impact Message from March 12, 2026. (MyAccess required) 

• Now – September 2026: Expect noise and vibration near adjacent floors during window removal and installation on levels 6 and 7 in the Clinical Sciences Building (CSB), near the bridge, to support space improvement project and the bridge connection work between CSB and BRAB. The UCSF community can view a Construction Impact Message about this work.
• Now – June 2026: CSB occupants on floors 5-7 can expect intermittent noise and vibration during window removal and installation on levels 6 and 7. This date was extended due to unforeseen site conditions. The UCSF community can find additional information in this Construction Impact Message from March 12, 2026. (MyAccess required) The whole partial renovation of the space in CSB on level 7 is expected to be completed in December 2026.
• March – November 2026: Expect intermittent construction activity related to underground utility work along Parnassus Avenue between Third and Fourth avenues. Traffic control and pedestrian rerouting will occur as needed during this work.
• Curtain wall installation continuing upward through Level 9.  
• Tower crane hoisting of equipment to upper levels expected Monday through Saturdays.
• Interior construction activity will increase as the BRAB curtain wall enclosure progresses, with minimal impacts. This includes fireproofing, mechanical installations, interior wall framing, plumbing, electrical work, and fire sprinkler systems. Because the work is underway inside the building, crews will be completing this work during longer work periods later in the day and on Saturdays.
• Traffic and pedestrian movement around the BRAB construction site continues to be actively managed. Traffic flaggers are positioned at Parnassus Avenue at Fourth and Third avenues to support safe inbound and outbound construction deliveries. Also, flaggers are monitoring traffic for the project on Koret Way.
• Ongoing façade and equipment deliveries are being staged from Koret Way. Koret Way remains restricted with intermittent access for pedestrians between 7 a.m. and 5 p.m. Monday through Friday.
• Construction Hours: Regularly scheduled BRAB construction activities are 7 a.m. to 5 p.m. Monday through Friday, with occasional work occurring within the Environmental Impact Report (EIR) hours on the weekends. Construction hours will change during some work, including early morning concrete pours.  
  • Site utility work will occur between 12 p.m. and 8 p.m. on an intermittent basis between March – November 2026.  
• Dates and details are subject to change. 

The UCSF community can watch a 25-minute PCCSI virtual town hall from February 25, 2026, to learn about project updates and the latest impacts. (MyAccess is required.) 

• Koret Way will continue to be closed Monday through Friday, with intermittent access for pedestrians, as a safety precaution for UCSF Real Estate capital project construction activities. A traffic coordinator manages vehicle gate access on Koret Way during normal business hours, and UCSF Facilities Services manages access after hours. Any future access changes along Koret Way will be communicated to the UCSF community.
• ‌An emergency egress route (MyAccess login required) has been established for Clinical Sciences Building (CSB) occupants, which leads outside south of the building to Koret Way.‌ See the map below for details. 

• UCSF community: Watch a 25-minute virtual PCCSI Town Hall from February 25, 2026, to learn the latest updates on the project. (MyAccess required).
• Now through March 2026, heightened construction noise and vibration are expected near the SON building demolition site and Saunders Court at Parnassus Heights. Following the demolition, noise is expected through 2026 for utility work needed to support the project and west development. 
  • Noise and vibration are expected to impact ‌‌the following buildings:
    • ‌‌Clinical Sciences Building (CSB)
    • Health Sciences East and West (HSE and HSW)  
    • ‌Ray and Dagmar Dolby Regeneration Medicine Building (IRM)
    • ‌Medical Sciences Building (MSB)
    • ‌Koret Hall (Koret Vision Center)
    • Possibly other nearby buildings adjacent to Saunders Court.
  • ‌‌If construction is impacting your UCSF research, please contact [email protected].  
  • If you are a UCSF employee and PCCSI construction is impacting your operations, please contact the project team at [email protected] or your supervisor/manager.
  • Dust management measures and environmental monitoring continue throughout demolition activities.  
  • Sound-dampening strategies are used on equipment where feasible to help limit noise impacts.  
  • Departments experiencing operational disruption may request support in identifying alternative workspace options.
• Earplug Stations: To help minimize the impact on those in nearby UCSF buildings, earplug stations are operational in the Clinical Sciences Building (CSB), the Medical Sciences Building (MSB), and the Health Sciences West and East towers. The stations dispense one pair of earplugs at a time to ensure availability. 
  • See the map below for the locations of earplug stations.‌
• Pedestrian access remains open on the east side of Saunders Court. Please follow fencing and wayfinding signage to safely navigate around the SON building.
• Koret Way access will continue to be closed with intermittent openings to support safe construction operations. Truck deliveries will be on Koret Way.
• UCSF Facilities Services, in coordination with the PCCSI project team, will communicate utility shutdowns to impacted building occupants as needed.
• Construction hours are 7 a.m. to 5 p.m., Monday – Friday, and 8 a.m. to 5 p.m. Saturday and Sunday (as needed), to better support project progress while reducing the duration of impacts on the UCSF community and beyond. ‌Construction for the project adheres to the Comprehensive Parnassus Heights Plan (CPHP) Environmental Impact Report.
