Depot Office Center Parking Ramp

  • Location: Minneapolis, MN
  • Architect: ESG Architects
  • Client: CSM Corporation

Project Highlights

  • 290 stalls
  • Three levels
  • Precast concrete


This three-level, 290-stall ramp is shared by tenants of the Depot Office Center and Metropolitan Lofts. It was designed to meet regulations requiring it to be obscured from street view, which is done by partially tucking it into the first floor of the Depot Office Center building. The overall structural system of the ramp is precast concrete on a conventional spread footing foundation. A sloped drive lane in the center of ramp uses precast bearing walls on each side. Precast double tees are used for the floor located inside the office building. Along the common wall of the office/parking area, the steel columns from the office building above were transferred out using steel transfer girders to maintain the required drive aisles for the parking area. An expansion joint was placed through the parking level along this line to isolate the office building from the thermal movements of the ramp. Ten-inch-thick precast bearing walls between parking and office on the east and parking and the lofts building on the north provide fire separation. Residential garages for some of the loft owners are built on top of the ramp’s double tee structure.
