North Laurel, MD
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.
