Portland State University, Campus Utilities Loop

The PSU Campus Utilities Loop was completed to provide needed utility capacity to address consistent growth of the urban campus. Fortis replaced the existing steam-and-chilled-water piping throughout the campus and installed new utility tunnels, chillers and emergency generators. In the existing tunnels, Fortis replaced 1,500’ of 6” chilled-water piping and 1,200’ of 8” and 12” steam piping. In the new utility tunnels, which are 900 linear feet of concrete box culverts that are 10’ x 12’ wide, new utility services were installed with 2,600’ of 18” chilled-water piping and 1,300’ of 12” high-pressure steam piping. The final “loop” connects the West and South ends of the campus to the North and East. Fortis also delivered a 1,000-ton chiller plant tied into the loop.
