Renovation of an educational facility in Aurora, Colorado. Completed plans call for the renovation of a educational facility.

Typical for this type of older construction, steam convectors are installed below most windows and radiate heat when the steam flow is turned on. Temperature control ispoor with a manually adjusted control valve at eachunit. Steam service to this system is activated seasonally and is turned off in the summer. Environmental control is poor and occupant complaints are frequent. Additionally, the old steam and condensate piping is very old and with expected corrosion, leaks are many. Water damage is a frequent problem. Steam distribution in this manner is not a current best practice and should be modernized. This project consolidates the (3) Building 500 East Wing heating water systems into one system. This includes increasing heating water pump and piping capacities, as well as providing new heating water supply and return risers to connect the existing heating water piping in the west wing lower levels. This project also includes an additive alternate for the remaining West wing. All campus standards and project drawing and specifications shall be followed for this project. The project includes removal of steam and hydronic piping, associated insulation, mechanical equipment which includes convectors, steam-to-hot water heat exchangers, pumps, and their controls as shown on the construction drawings. Some piping insulation to be removed could contain asbestos and will be coordinated with the owner. New work includes replacing the heating water pumps and increasing heating water piping sizes to accommodate the combined heating water load. This piping will be extended to the new heating water riser. Additional piping will be enlarged and added as shown on the plans. Sprinkler piping in mechanical rooms and other spaces may need modification to accommodate the new installations. Minimal drywall and ceiling repairs required due to the mechanical scope. The new equipment such as pumps and convectors will be connected to the building automation system.
