With the last steel beam lifted up to the sky, the tallest building in Beijing, China Zun topped out successfully on 22 August.

China Zun Tower stands out in the capital city’s Central Business District opposite another well-known Arup project – the CCTV Headquarters. Arup have acted as the structural and geotechnical engineer for the project since 2011, as well as providing fire and security consultancy. We engineered a highly efficient tube-in-tube structural system composed of perimeter mega structure and reinforced concrete core.

The current elegant curved shape was also the result of many scheme study runs. The geometric complexity was further combined with the challenge of engineering a viable seismic structural system for such a tall building with its unique enlarged zun-top.

Our engineering team developed and applied parametric structural modelling tools which significantly increased our design efficiency and enabled a quantitative feedback to our client in a very short time. With more than 800 options studied together with the architect KPF in a holistic design environment during the scheme design and pre-design stage, Arup managed to deliver a safe, cost-effective and sustainable structural solution.
