Arup & PYD (Engineer of Record)
Grupo A, QBO
At 46 storeys this ambitious project is the tallest office building in Colombia. The structure is a technological advancement in the field of composite high-rise construction, combining state-of-the-art steel construction with local concrete practice to deliver innovation economically.
The structural design was highly integrated with the client’s vision for a new cultural symbol for the city of Bogota. The structure efficiently resolves dramatic cutbacks at the base of the tower, which form a key part of the architectural concept. This was achieved by utilising the building’s lateral bracing tube to act as a rational and efficient multi-storey cantilever.
The use of materials was minimised by utilising high performance seismic systems together with efficient structural forms.
The project leaves a positive legacy on local steelwork capability. By upskilling local labour to carry out erection and field welding of special seismic connections the local market now has the capability to deliver similar scale and specification projects without importing these elements.
