Ramboll was appointed as structural engineer on this project.
The main vertical elements are reinforced concrete, providing stability against wind and seismic activity. The floor slabs are post-tensioned concrete. The structural integrity of these slabs presented a challenge as it featured a typical step between the office section and the rest of the floors and contained a large opening that formed a ‘U’ shape to the floor plan.
A number of column and shear walls were transferred from one location to another at the lower tower area which were quite distinctive structurally.
A separate car park building, 16 storeys high, with a swimming pool and gymnasium on the roof, were also designed by Ramboll, incorporating reinforced concrete on the ground floor with steel columns and beams supporting the composite metal decking slabs on the floors above.
