Empire Tower

Al Reem Island, Abu Dhabi, UAE ¤

Elegant and simple architecture that translates into a complex geometry challenge for our engineers.

The simple design of this 58-storey Empire Tower, inspired by twisting clay and bringing to mind a folded paper fan, maximizes views over the Gulf. 

Material technology innovation

 

During concept stage, our structural engineers designed a state-of-the-art composite transfer slab structure to free up interior spaces in the building.

Structural loads are typically transferred from one floor to another with all columns in line vertically, which would have placed columns in undesirable locations.

By applying 3D structural modeling, we relocated interior columns into more desirable positions.

The structural load is therefore directed laterally across the floor plate, and transferred down a different column. Pioneering this transfer method, our engineers used high-strength concrete and steel to create a slim floor plate that is able to resist seismic activity.

Inclined façades and high wind pressures

With walls sloping both in and out, and at varying angles, our façade engineers were faced with a complex task. Inclined façades and high wind pressures can result in over or under-specified glass thicknesses.

Convex curves and micro-risers

To accommodate the building’s curve, our building services team had to adapt the services. Typically, there would be a large single central riser distributing cooling, electricity and plumbing to each floor throughout the building. Given the twisting leaning nature of this tower, we designed a series of smaller risers from the lower ground floor instead. These micro-risers follow the vertical incline of the building and enabled us to slim the ceiling void at every level, reducing the overall height of the building and saving our client money.
