Engineering design for tall buildings recognised

• CITIC Tower, Beijing – Fire & Risk Engineering Award and Best Tall Building (400m and above)

Arup acted as the structural and geotechnical engineer for this iconic landmark. We engineered a highly efficient tube-in-tube structural system composed of perimeter mega structure and reinforced concrete core which significantly increased our design efficiency in delivering a safe, cost-effective and sustainable structural solution to our client. We also provided fire and security consultancy, optimising evacuation provisions and conducting complex fire analysis to ensure the robustness of the building under fire conditions.

• Raffles City Chongqing – Fire and Risk Engineering Award, Structural Engineering Award and Best Tall Building (300-399m)

Working with Safdie Architects, we addressed the structural challenges posted by the tower’s slenderness ratio over 9.4. We adopted four mega corner columns connected to the central core wall via diagonal outriggers and belt trusses. We tailor made a patented hybrid outrigger system using concrete walls, steel bracings and a structural ‘fuse’ to provide stability to the building against strong wind and earthquakes. Fire modeling analyses were also conducted for the Conservatory skybridge on top and podium levels to assess the evacuation provision and optimise the structural fire protection.
