I-90 Cleveland Innerbelt | Cleveland, OH

The Cleveland Innerbelt Modernization Plan included reconstructing five miles of busy highway, including the construction of two new bridges to carry traffic. We were contracted to install drilled shafts for two piers for a new bridge alignment.

Crankshaft Press | Sharon, PA

A new crankshaft press constructed in Sharon, PA required temporary support of excavation. We were chosen as the design/build contractor for the SOE solution, which was constructed using drilled shafts.

What are drilled shafts?

Drilled shafts, also referred to as drilled piers, caissons or bored piles, are deep foundation solutions used to support structures with large axial and lateral loads by excavating cylindrical shafts into the ground and filling them with concrete.

How do they work?

Drilled shafts are typically designed and constructed to support axial forces through a combination of side friction and end bearing resistance. They range in diameter from 24” to 120” and can be installed to depths in excess of 300 feet.

Why do you need drilled shafts?

Drilled shafts are an economic solution that can be installed in a variety of different ground conditions to accommodate large axial, lateral and overturning forces.
