The $51-million upgrade and expansion of the 40-year-old University of Colorado Boulder Recreation Center has been a real workout for contractors, led by Centennial, Colo.-based Saunders Construction Inc. Crews gutted the original 235,242-sq-ft building on the Boulder campus and are replacing electrical and mechanical systems as well as adding 70,000 sq ft of new space. The project's mechanical upgrades include one of the most sophisticated, sustainable air-displacement systems ever used in a university rec center. Working as the project's general contractor, Saunders is building the project to net-zero LEED Platinum standards and says it expects to achieve the Platinum rating.
"CU wanted a unique energy-conserving system, and there's nothing standard about this system," says Rick Osbaugh, director of advanced energy systems at The RMH Group Inc., Lakewood, Colo., the project's lead mechanical engineering firm.
