Distinctive in both shape and function, the 62-story, 709-ft-tall condominium tower features a one-of-a-kind undulating structural exoskeleton consisting of 5,000 custom-built glass-fiber reinforced concrete (GFRC) panels. Designed by world-renowned architect Zaha Hadid, who died before the project was completed, the unique exoskeleton forms curving X-braces that helped minimize the internal shear wall system.
通过加入11。——联合国厚楼板ique structural design requires only two internal columns, with interior clear spans up to 45 ft from core to glass, providing residents with a greater sense of openness. Even so, the building is as structurally rugged as it is distinctive, with the capability to withstand hurricane-force winds.
Because the complex, curving exoskeleton incorporates cross sections that change in shape and dimension with each floor, permanent GFRC formwork doubled as the final finish of the structural/architectural elements, a more advantageous strategy compared with conventional forming approaches. Working with a GFRC formwork fabricator based in Dubai, the project team developed a detailed logistics schedule, building in sufficient lead times so that components arrived well in advance of installation. Extensive quality-control measures in both countries ensured the formwork met the precise structural specifications and arrived at the jobsite undamaged and ready for assembly.
Each section entailed a complicated rebar design, with multiple angular projections that likewise required detailed design and inspection prior to pouring concrete. Lower sections measuring as much as 25 ft long and 5 ft thick were simplified into rectangular sections, then clad with GFRC panels. This approach cut approximately four months from the project schedule.
As one edge of the building’s podium lies just 6 in. from a neighboring building, the foundation system of nearly 230 30-in.-dia auger cast-in-place piles is designed to minimize the potential for settlement. One pile was driven to more than 170 ft, the deepest pile ever driven in Miami-Dade County at the time. The 12-ft-thick, 147-ft by 149-ft mat required approximately 9,500 cu yd of concrete, which was poured in one continuous 26-hour placement and supplied by nearly 1,000 concrete trucks.
After 40 months of construction that included safeguarding the then-uncompleted tower against a Category 4 hurricane, what was once described as “an impossible build” introduced a bold new silhouette to the Miami skyline.
