Bradford White Piers

Story

A large appliance manufacturer needed to extend their facilities.  Part of that expansion included a long narrow room alongside an existing portion of the facility.  The soil borings indicated fill at the top of the site and some lenses of peat and other compressible material farther down which limited the capacity of the site to hold the new much heavier load.  They needed to transcend the weaker soils and lock into the stratum at 38-42 feet.  The choice was new construction helical piers, which could be installed through the poorer soils and load up in the much stiffer elevation, thereby giving the needed capacity.  The 4.5 inch diameter pier was selected because of a very strong section modulus for column stiffness and 156,000 pounds of compression capacity.  The engineer laid out the piers to match the loading.  The piers were capped with a custom designed bracket to maximize bearing capacity for the grade beam and stability in the beam.  The engineer selected galvanizing as a necessary corrosion protection.  The project was completed in approximately 2 days' time, with all piers reaching specified capacity, including the required factor of safety.  The piers were ready for immediate loading application.  The customer was pleased with the timeliness and the neatness of the installation.
