When complete, the Treasure Island C2.4 project will be an 18-story residential tower rising above two low-rise building wings on the much anticipated Bay Area community development. The concrete tower will have 244 rental units, one below-grade parking level for 109 vehicles, lobby, café, central courtyard, and rooftop solar panels.

DCI’s San Francisco team is the engineer of record designing the primary lateral and gravity systems of the residential tower. The team is detailing the layout for the tower’s podium base and parking level for flexibility and for meeting the strict torsional limits of the project site. The floor system at-grade level will be mild reinforced concrete. Concrete shear walls will be arranged around the elevator and stairwell cores to minimize architectural layout. The above-grade residential slabs will include PT concrete to help reduce seismic mass.
