This seven-story university building is located in Northeast Arizona. The large structure was constructed utilizing large belled concrete piers drilled down 12’ below grade with intersecting grade beams between the columns.
A major leak in the water supply system allowed the building to fail at the columns and created an upheaval in the floor slab system.
Working with a local General Contractor, Power Lift installed 330 steel pilings on existing and newly built structural beams installed in the lower level. We needed to add load bearing capacity to the original concrete columns and add support for the 8” structural slab to be repoured. Several tons of rebar reinforcing was added to the structure incorporated in the new beams and floor slab.
Soil borings indicated that sufficient bearing was located at 45’. Final depths ranged from 45’-50’.
