Capabilities: Earth Retention | Deep Foundations | Design Build | Earthwork | Environmental

South Minneapolis Regional Service Center was a best value public bid to construct a 4 story building with 2 stories of underground parking within 5-ft of an occupied building.  Bolander proposed a value engineering alternate to the project providing over $1M of savings.  Our scope included:

  • Select demolition of the existing building
  • Removal and disposal of over 20,000-ton of environmentally impacted soil
  • Drill and set 50-ft H-Pile with 10-ft bedrock embedment within 5-ft of an occupied building
  • Permanent H-Pile and Lagging system
    • 25-ft vertical face
    • Designed to support both occupied building and soil pressure loads
    • Designed to act as a one-sided form for the proposed building
  • Temporary H-Pile and Lagging system
  • Micropile foundations to prevent differential settlement
