Construction workers broke Florida records on Saturday when they undertook the largest concrete pour in state history. The workers were forming the foundation of Panorama Tower, an upcoming mixed-use project at 1101 Brickell Avenue.

Crews and concrete trucks gathered at midnight Friday to begin the massive undertaking: For the next 22 hours, 175 concrete trucks ferried 1,200 loads to the project’s 220 carpenters, laborers and steel workers, who worked to build what developers say will be the tallest residential building on the East Coast south of New York.

By 10 p.m. Saturday, workers had formed the single largest foundation in Florida’s history, and conducted Miami’s longest continual concrete pour, according to a release.

When complete, the 83-story tower will house 821 rental units, 100,000 square feet of medical offices, 50,000 square feet of retail and restaurant space on the bottom two floors, and a 2,000-space parking garage. The building’s residential portion will sit on top of a 19-story podium where the retail, office and parking spaces will be located.

The building is being developed by Florida East Coast Realty, which plans to finish the $800 million project by 2018. The developer recently received a $340 million construction loan arranged by Wells Fargo Bank. — Sean Stewart-Muniz
