Construction in such close proximity

This open waterfront concept could only be realized by ‘hiding’ the parking garage underground—a challenging and costly approach that contrasts sharply with typical condominium developments in South Florida, which tend to feature a pool deck situated high atop several levels of parking. To create the underground structure, the development, design, and building teams worked closely together to determine the best method for subterranean to the bay.
236-car garage for Una Residences will cost $25 million to build.
Reaching nearly 15 m (50 ft) and three stories below sea level, the 9290-m2 36-car garage for Una Residences will cost $25 million to build.
To build a garage that does not flood, the building’s general contractor, a joint venture whatsapp number database between Civic Construction and Ant Yapi U.S., along with specialty subcontractor Keller International, set out to create a massive watertight concrete box deep underground. Using highly advanced technology and equipment, the complicated undertaking requires workers to drill 800 holes 15 m deep into the ground and fill them with concrete and water. The interlocking pillars create a cement block that is hollowed out to build the garage.

Following the building’s groundbreaking earlier this year, the construction team embarked on the deep-soil-mixing construction process to create a giant waterproof ‘bathtub’ that protects the building’s concrete mat above the tub from the groundwater and forms the base of the garage.
