McCrossin Foundations was subcontracted to install the drilled shafts for the building foundation and a cantilevered precast lagging soldier beam retaining wall.

The caissons ranged in diameter from 30 to 60 inches and depths up to 35 feet were drilled, as well as a structural rock socket up to 10 feet. The caisson shafts were drilled primarily through fills, weathered shale and limestone. Due to the underlying materials and existing site conditions, some shafts required temporary casing during installation. McCrossin Foundations was responsible for pouring approximately 700 cubic yards of concrete using the free fall method, as well as installing the pre-tied reinforcing caisson cages.

The soldier beam wall scope included the design, engineering and installation of 2,400 square feet of a soldier beam and wood lagging wall.
