UK-based engineering practice Arup said that it is working on five tall buildings in Mexico City, which are currently in various stages of design and construction.
The buildings include Torre Manacar, Torre Pedregal 24, Torre Reforma, Punta Chapultapec and BBVA-Bancomer Torre Ejecutiva.
Arup is working with Teodoro Gonzalez de Leon Arquitectos on Torre Manacar and Torre Pedregal 24.
Situated on Avenida Insurgentes Sur, the 30-storey Torre Manacar is expected to be completed in late 2014.
Arup developed a structural scheme for Torre Pedregal 24, which cantilevers the front of the building nearly 60m over a pavilion designed by the architect Vladimir Kaspe.
The V-shaped building was balanced on a single pair of mega-brace columns per facade and the lobby levels of the structure will provide unobstructed views into the park.
Arup said it has used advanced seismic design and analysis techniques to deliver the structural design keeping in view the specific seismic hazards of Mexico City.
The lateral loads have been designed to be shared between a central reinforced concrete core system and the perimeter mega-brace system.
The company is working with Benjamin Romano Associados on Torre Reforma, which will feature a concrete core wall lateral system with sloping brace elements on the front facade to cantilever the building over another hacienda and provide a 57-storey tower without a single continuous vertical column.
Arup has also provided a sustainable design for the building services and facade to achieve LEED Platinum rating.
In the neighboring block, the company is working with architects Taller-G to design Punta Chapultapec, a 236m mixed-use tower adjacent to Chapultapec Park.
Demolition of the previous building is complete and tendering is currently under way for the substructure works.
Arup worked alongside architects Rogers Stirk Harbour + Partners and Legoretta + Legoretta to develop an eccentrically braced mega-frame for BBVA-Bancomer Torre Ejecutiva across the street from Punta Chapultapec.
The company said the frame will cover around the tower’s perimeter, freeing the internal floor-plate and creating a ductile seismic resisting system.
