Innovative repair methods used on a South Florida high-rise corrected problems caused by poor construction practices. The building's floor structure consists of a two-way flat plate that is continuous with 8-foot cantilever balconies. The 8.5-inch-thick balconies surrounding the building perimeter were found to be structurally deficient. The top reinforcement was placed too low in the balcony slabs. Reducing the distance between the top steel and the bottom of the concrete slab reduced the slab's ability to resist cantilever forces.
