St. Petersburg is fast becoming one of Florida’s most desirable cities to live and work in—and that popularity is causing a housing shortage. Once a hotel parking lot, the 35-story Saltaire fulfills a need for high-end condominiums. The building consists of ground-level retail space and six levels of parking underneath a seventh-floor amenities level. From there, a 28-story tower rises. The luxury residential tower overlooks Tampa Bay and is in walking distance of downtown attractions.
Ceco provided turnkey concrete services for this project, which consisted of 35 elevated post-tensioned (PT) concrete decks. The PT and lightly reinforced slabs connect to massive and heavily reinforced shear core walls. With a typical level measuring approximately 19,000 square feet, Ceco placed a total of 41,763 cubic yards of concrete and installed 6,053 tons of rebar plus 1,315,000 pounds of PT tendons.
By using a PT concrete flat slab structural system, engineers were able to design 8-inch slabs for the building. The thinner slabs ensure a lighter structure than one built with conventionally reinforced concrete slabs and reduced material costs.
Formwork systems used included Ceco’s HV forming system for the tower as well as a parking garage located on the project site. Once the Ceco crew climbed to Level 8, they used table trusses for all remaining levels.
Project owner KT St. Pete Bayfront acquired the downtown property from Hilton Hotel, which operates next door to Saltaire and used that property as a parking lot. As part of the deal, the Saltaire project included simultaneous construction of a new parking garage for the hotel.
The parking garage opened to the public once complete, which presented several logistical challenges for the ongoing tower construction. The crew was not allowed to use a crane to fly material over the operating garage, located on the west side of the jobsite, resulting in limited laydown area.
Ceco’s experienced team leaders and management worked closely with general contractor KAST Construction and other trades to overcome logistical and material delivery challenges and resolve issues quickly. The Ceco team also negotiated use of a neighboring building’s driveway to unload trucks delivering rebar.
As a result, the Ceco crew met and exceeded the project schedule.
