Abstract: The South Florida beachfront is awash with an ever-increasing number of high-rise condominiums. As land becomes scarcer and increasingly expensive, and building regulations change to require above-grade floors to be commercial or residential units, developers must locate parking below grade. However, given a subsurface profile consisting of highly porous limestone, together with a shallow groundwater table, maintaining a dry excavation for underground basement construction is a significant challenge.
