Hudson River Ground Stabilization

The design-build scope includes modifying and stabilizing a 1,200-foot section of soil in the shallow area of the Hudson River near the Manhattan shoreline to prepare for tunnel boring operations. The scope includes:

• Geophysical and bathymetric surveys to assess riverbed conditions
• Removal of obstructions and installation of a steel pipe pile and sheet pile combi wall containment system
• Execution and verification of ground improvement methods to support tunnel boring
• Environmental monitoring and compliance throughout construction

Construction is expected to be completed in 2027. The work will create stable soil conditions for future tunneling.
