Structural Systems Repair Group (SSRG), with headquarters in Cincinnati, OH, was contracted by Model Group, to install 11 helical piles as a deep foundation system to support existing building foundation walls in OTR Historic District, Cincinnati.
jt. ·_)
Corner section of the existing building foundation wall had deteriorated and collapsed beyond repair due to settlement in poor soils. SSRG was contacted by Model/Schaefer to propose a helical pile foundation stabilization solution at this corner section. Considering very poor soils, grouted piles with 6-helix plate configuration were proposed as an effective solution to achieve required capacities. 6 of these piles were installed on exterior wall using miniexcavator mounted torque drive (40-ton ultimate capacity) and remaining 5 were installed on the inside in basement using hand-held torque drive (25-ton ultimate capacity).
