Heating Hot Water Loop Replacement

SFSU utilizes a Heating Hot Water system to condition most academic buildings on campus. Thermal heating is generated by boilers at the central plant, then delivered to buildings in 8” to 12” underground mainlines. To combat corrosion and increase reliability, this project replaces the piping and valves that comprise the system. The original ductile iron carrier pipe is being replaced with high density polyethylene, which is a piping material that will provide much greater longevity for the system.

Summer 2026 is the second major phase of this project. Due to the disruptive and large scale nature of the work, the construction sequencing is phased to occur during the summer months. Work will occur in the Central Quad and in the area between the Science and Business buildings. Construction activities will include excavation, piping installation, and restoration of affected areas. The work zone will be fenced off, and pedestrian access through the area will be restricted. Expect increased construction noise, equipment, and truck activity in and around the work area during standard work hours. Please use caution when traveling near the site. Access to building entrances will be maintained, however routes may be adjusted as work progresses.
