Construction on Tacoma Community College's Harned Center For Health Careers Begins Monday (UniversityPlacePatch)
Harned Center construction starts with the building’s geothermal heating/cooling system. More than 100 geothermal wells will be dug in Parking Lot C. In addition, a large storm water vault will be installed in Parking Lot D, and connections to city water and other services will be installed.
150 geothermal wells, located in Parking Lot C and the campus central quad, will provide heating and cooling for the Harned Center. Well-drilling rigs will be in place at the geothermal dig locations for about four months.
