Rapid City Regional Hospital Campus Office Building, Rapid City, SD
Dollar Value: $7.0 Million
Square Footage: 36,723 SF
Owner: Rapid City Regional Hospital
Architect: HDR Architecture, Inc.
General Contractor: Scull Construction Service
The Rapid City Regional Hospital Campus Office Building is a three story approximately 36,700 square foot structure. The structure is founded on drilled piers and grade beams with the first floor being a slab on grade above engineered fill. The second and third floors are each framed with composite steel beams supported on steel columns, and the roof structure is to be constructed with steel deck supported by bar joists and steel girders.
Durability was a big factor in the selection of the tilt-up panels for the Central Utility Plant. The lower cost of tilt-up as compared to precast panels and the ease of adding insulation between wythes made it the best choice for housing mechanical equipment at RCRH.
Due to the soil conditions at the site drilled piers were used as the building foundation. Tilt-up panels eliminate the need for grade beams as they are designed to span from pier to pier.
The utilities were routed from the central utility plant to the existing hospital through a new approximate 10 foot wide, 12 foot tall, 300 foot long underground tunnel. The tunnel was founded on micro-piles due to the close proximity of the tunnel and the existing structures The north end of the new tunnel was actually constructed through the old central utility plant.
