W Austin Hotel and Residences in Austin, Texas. Left image courtesy Andersson-Wise Architects.
Thornton Tomasetti provided structural engineering for the one-million-square-foot, LEED Silver urban complex that includes a 35-story tower with 200 luxury condominiums and a 250-room W Austin Hotel. The building’s podium houses retail space, office space, restaurants and three levels of below-grade parking. An amenity level with pools for the hotel and the condominium tower is located above the podium. The centerpiece of the development is an attached 2,750-seat theater where the PBS live music show “Austin City Limits” is recorded.
The hotel and condominium portions of the structure are composed of post-tensioned slabs. The majority of the podium is a conventional concrete structure, while the theater portion is framed with structural steel. The stacking of multiple occupancies drove the selection of the structural systems.
