Due to extremely poor soil conditions, the foundation system included a combination of eighty-two Geopiers and helical piers before a conventional concrete foundation could be constructed. The building pad and paved areas were over excavation by 24” for the placement of structural fill (RC-6) which was spread and compacted in 8” lifts. The new structure includes concrete wall footings, load bearing CMU walls and wood trusses.
