Load Testing Setup
Pre-production load test utilizing four Model 287 reaction piers rated at 50 kips each, providing 200 kips of reaction resistance. The production pier achieved 106 kips ultimate capacity during testing.
Helical Pier Being Driven
Helical pier installation in progress using high-torque hydraulic drive equipment. Installation torque was monitored to verify load capacity as the pier advanced through soft soils toward stable bearing strata.
Wide View of Installation
Field installation of helical piers supporting a 280,000-pound precast utility building. The Eskridge D600 drive system (54,000 ft-lbs torque) provided the capacity required to reach approximately 75 feet below grade.
Drive Head Detail
Eskridge D600 hydraulic drive head delivering up to 54,000 ft-lbs of torque during helical pier installation. Installation torque was monitored throughout advancement to verify load capacity and ensure each pier achieved required performance criteria.
Helical Piers Staged for Installation
Galvanized helical pier extensions staged on site prior to installation. Each pier section is engineered to transfer structural loads to deeper, stable soil layers.
