It took almost 700 construction workers to pour the foundation for CMC Group’s Brickell Flatiron condominium. Moss & Associates, general contractor, coordinated the continuous 24-hour concrete pour at the jobsite. About 150 ready-mix trucks carrying 1,250 truckloads rotated in shifts to pour about 12,500 cubic yards of concrete weighing more than 50 million pounds into a large excavated hole for the tower’s concrete mat.
Ready-mix trucks were released in waves and escorted by Miami- Dade Police from the staging area heading north on South Miami Avenue to the pumps. All pumps were positioned to allow for a ready-mix truck to simply pull past and back into position. Pumps were set up to have two trucks at any given time. Five pumps were used during the pour and there were no issues with pumps or hoses.
The pour, which ended around 10 p.m. on Jan. 7, created the condo tower’s concrete pad atop 700 steel pilings, each dug 100 feet deep. Brickell Flatiron’s foundation pour was the fifth largest condo foundation pour in the entire Southeast U.S.
Hovering 736-feet above street level, Brickell Flatiron will be one of the tallest residential towers in the U.S. upon its completion. With its distinct flatiron shape and position at the epicenter of downtown Miami’s Brickell Financial District, the 549-unit building was designed by architect Luis Revuelta and interior architect Massimo Iosa Ghini.
Unit prices range from $465,000 to $2.5 million, with penthouses priced up to $15.5 million. Construction of the 64-story tower began in March 2016 and is slated for completion in 2019.
