Wagman Geotechnical Construction Project

North Laurel Pumping Station

  • Location

    North Laurel, MD

  • Duration

    September 2009 - October 2009

Wagman’s Geotechnical Construction group provided design and construction of excavation support for the North Laurel Maryland Pumping Station. The project required the construction of a 60 foot wide by 60 foot deep box with hardwood lagging and rock fall fencing. Drilled-in soldier piles were installed for the purpose of both excavation support and site dewatering.

Key Challenges & Project Details

  • The piles were installed utilizing a micropile drill rig in order to penetrate the bedrock.
  • The compressive strengths of the bedrock were up to 1,700 psi.
  • Pile lengths averaged 43 to 45 feet in order to achieve adequate bearing capacities.
  • Wales and bracing were provided to stabilize the box during excavation.
