Sharp Memorial Hospital

The Central Tower of the Sharp Memorial Hospital underwent a seismic retrofit in order for it to be designated as SPC-2 and allow the structure to remain in service through 2030. Part of the seismic retrofit involved the installation of 76 ea. difficult access micropiles to in installed inside the hospital. Condon-Johnson designed the micropiles for ultimate load capacities of 616 kips in compression and 313 kips in tension.

During mobilization and installation of the micropiles the hospital was required to remain in full operation. This was obtained by having a negative air chamber in the construction area, an outside staging area, team coordination, limited noise, and a safety first culture.
