Discover how advanced PT products and services made the Porsche Tower’s Radial layout possible.
Suncoast recently contributed its post-tensioning expertise to constructing the Porsche Design Tower to stabilize each level of the 60-story building in Sunny Isles Beach, Florida. Suncoast’s combination of engineering talent and service excellence helped increase safety and efficiencies and reduce risk in this high-profile project.
60-stories of stability
Suncoast’s proprietary SRS® package and post-tensioning tendons reinforced the Porsche Design Tower, a 60-story, $560-million residential condominium. Nestled in the heart of Sunny Isles Beach, Florida, the Porsche Tower will include the first automated vehicle elevator parking system used in a private condominium project in the US.
This project posed multiple challenges; a workable concrete pour sequence was needed for the building’s three core areas, at a rate of one floor per six days. To satisfy this rapid schedule, the team placed each elevator/stair core in a separate pour on each floor, then used interior stressing blockouts for stressing portions of the banded ring beam tendons. This enabled the setting of complex vertical formwork in segment one; the slab reinforcing, Suncoast SRS® and PT to be set in segment two; and slab formwork to be placed in segment three – enabling all trades to work daily during the floor cycle.
Unbonded PT system benefits
- Efficient and cost-effective reinforcement
- Allows for reduced slab thickness
- Enables lower overall building height
- Improved deflection control
Reliable reinforcement, revolutionary design
The Suncoast SRS® package includes carbon steel and factory-welded Nelson Punching Shear Resistor studs, which are used in the flat-reinforced concrete slabs and footings in the Porche Design Tower.
- Punching sheer resistance can replace or supplement stirrups, drop panels, or column capitals
Suncoast’s unbonded post-tensioning system provides an efficient, cost-effective reinforcing system for elevated slabs. Suncoast provided 1.25M lbs of encapsulated PT materials for the Porsche Design Tower and 6,700 pieces of SRS.
