  • Booster station design and water main piping

Site Development

DGR Engineering (DGR) contracted directly with MPCH and worked closely with the Owner’s Architect, BWBR of St. Paul, MN during the planning and design phase. Planning started with site plan design for the new facility to offer maximum exposure to traffic on Highway 75. The hospital building is set back into a hill so that the site grading produced ample suitable soils to construct the building slab and parking lots.

The front parking lot is reserved for patients and guests and employee parking is located behind the building. Parking lot grades are pedestrian-friendly while maintaining good surface drainage. Traffic flow of patient, delivery and emergency vehicles was a point of emphasis during the design process. The employee parking lot accommodates delivery truck turning maneuvers and direct routes to the emergency entrance. It was also designed to be easily navigated for emergency situations.

The new hospital required construction of utilities service lines. A water main loop surrounds the building to provide fire protection and water service from several directions. DGR assisted Rock Rapids Municipal Utilities with design of a booster station and water main piping to provide required fire flows and improve water system pressure and flows in the southwest corner of Rock Rapids.

Floodplain Analysis

DGR employed a Geographic Information System (GIS) in conjunction with the U.S. Army Corps of Engineers to first determine the 100-year flood elevations and delineate the floodway boundaries.

Distribution Conversion

Due to concerns with the age and condition of the structures, along with safety clearances to energized equipment and conductors, a project was undertaken to replace the old infrastructure with new underground lines and associated padmount equipment.
