The $13.5 million University of Colorado Health Sciences Center, Aurora, Colorado, provides comprehensive services for the outpatient care and treatment of cancer and urology patients. The facility is a cast-in-place concrete frame building with a glass and brick veneer exterior. The building houses multi-disciplinary activities including outpatient exam and special procedure areas for cancer treatment services; patient support services; and clinical investigation.
For the floor and roof structure of the three-story building, a 24-inch-deep, wide module, or “skip-joist” concrete framing system was selected. The floor and roof framing is supported by a combination of square and exposed round concrete columns on a foundation of concrete spread footings. Cast-in-place shear walls on a mat foundation form the wind and seismic lateral load resisting system. The typical building bay size of 30-by-30-feet was pre-established by the owner and designed to accommodate an additional future floor level.
The first floor houses three linear accelerators that required rooms with concrete walls and ceilings of varying widths up to 8 feet 8 inches thick to shield harmful radiation generated by the equipment. The main lobby features a dramatic three-story interior space. The adjacent upper floors are set back from the exposed concrete columns with only the concrete beams extending out to connect the floor to the columns.
A concrete floor system was ideal for the owner requirements of strict vibration control criteria, heavy floor loads, and shallow floor depth to provide ease and flexibility for mechanical, electrical and pluming (MEP) systems design and installation. The inherent continuity of the cast-in-place concrete framing system provides unparalleled vibration damping characteristics. The resulting floors exhibit superior vibration control and fire resistance with no additional costs or delays in schedule and occupancy. Forming girder and beam soffits flush with the bottom of the joists simplified and maximized the clearances for mechanical and electrical equipment. They also afforded earlier project completion, and optimized total cost. The project received the 2000 Award of Excellence from the American Concrete Institute Rocky Mountain Chapter.
