The 360 Rosemary in West Palm Beach is a post-tensioned concrete building with a longform wide module pan joist structural system. One of the few concrete office buildings in South Florida, 360 Rosemary’s 45-foot-perimeter and column-free bays were achieved with only a 24.5-inch-deep structural concrete profile. Ceco provided the full concrete frame including foundations and crane hoisting for this project. More than 580,000 square feet of concrete was framed and poured onsite. Shell work began October 2019, and the building was topped out August 2020.
