Replaces approximately 16,070 linear feet of chilled water piping within the campus thermal infrastructure loop system. It also builds approximately 150 linear feet of new tunnel and hot water piping to enable increased redundancy in the hot water system in the northeast sector of the Fairfax Campus as well as building approximately 700 linear feet of new chilled water piping to serve and interconnect the northwest sector of the Fairfax Campus. Additionally, while replacing the chilled water lines underneath the north Plaza of the Johnson Center, it will upgrade and replace the failing paver system for that plaza. This portion of the project will be financed from the issuance of 9(d) bonds.
