Highlights
- All floors from the second level, up through the roof level, are composed of post-tensioned slabs.
- Reinforced concrete with conventional reinforced slabs are present at the ground and basement levels.
- The seismic system consists of reinforced concrete shear walls at the elevator and stair cores.
- The main project challenge was minimizing the structural element to make it fit within the small architectural footprint and unit layouts.
- We reduced the building mass by 10 percent to 15 percent with changes to the existing concept design done by another firm.
- We achieved the biggest gain by changing the residential floors from conventional 10-inch-thick concrete flat plates to eight-inch post-tensioned flat plates.
