Project details

What E2CR delivered

Scope

SPT borings and supplemental CPTs for toll plaza, ramp, and bridge replacement design.

Outcome

CPT testing produced modulus, shear strength, end bearing, and skin friction values roughly 1.5-2x higher than nearby SPT-derived values, supporting a more cost-effective design.
