Future residents of Bentley Residences in Sunny Isles Beach, Fla., may not realize that their 62-story oceanfront luxury condo tower rises from a bit of history: a 15-foot-thick foundation formed by the second largest continuous pour of concrete in the US to date.
Coastal Construction Group delivered and placed 20,000 cubic meters of concrete in a single 36-hour operation that began on the evening of November 14. The contractor says the spill required more than 2,100 trucks from two suppliers, coming from at least 10 different plants. A team of 250 workers took part in the pouring, which also required 2,400 tonnes of reinforcing steel.
Although the Bentley Residences foundation is the runner-up for the 21,200 cubic yards of cement placed for the Wilshire Grand Center in Los Angeles in February 2014, it holds the distinction of being the largest pour in Florida for a residential carpet foundation.
Vice President of Coastal Construction Jamie Corbett says four months of planning and preparation preceded placement, including numerous meetings with subcontractors and engineers from the project team, the City of Sunny Isles and the Florida Department of Transportation.
“We did several dry runs to make sure our plan worked,” Corbett says, adding that the painstaking advance effort paid off and resulted in a “flawless pour.”
“The vertical construction started the next day,” he adds.
Led by Dezer Development in partnership with Bentley Motors, the 716-foot-tall Bentley Residences will feature 216 luxury units, each with its own multi-car garage directly accessible by “the Dezervator,” a patented car elevator system that debuted in 2015 with Dezer’s nearby 60-story Porsche Design Tower. The project’s 20,000 square meters of planned amenities include a private restaurant, cinema, spa, gym and a landscaped beach club with cabanas.
Corbett says the tower is on track for completion in mid-July 2027, with delivery expected the following year.
