Thornton Tomasetti is providing structural engineering services for a new 22-acre urban mixed-use development consisting of residential, commercial, retail, hospitality and cultural buildings within a gated community. The project is divided into three phases of design and construction. The ongoing Phase 1 of this project includes multiple residential buildings comprising 90,000 square meters. The towers ranging from ten to 47 stories with three basement levels are integrated within the landscape to optimize energy efficiency and occupant comfort.
The structural system for the project, reinforced concrete frame, comprises shear walls to resist lateral loads and flat plate with columns to support gravity loads at the residential floors. Flat plates have folds to accommodate depressions, perimeter façade loads and terraces. A concrete flat slab system is utilized at podium and parking levels. The foundation system comprises a reinforced concrete raft at the shear walls and isolated spread footings at columns. The benefits offered by the structural system include speedy and efficient construction with the use of local material and M-50 grade concrete; aesthetically appealing beamless flat ceiling that yielded increased clear floor-to-floor heights; and a cost effective shuttering system.
Understanding and incorporating vernacular building practices and local materials for a seismically irregular structure were some of the challenges encountered by the design team.
