Arup’s tall building expertise has earned seven top accolades at the Council on Tall Buildings and Urban Habitat’s (CTBUH) Annual Awards, which recognise extraordinary contributions in the advancement of tall buildings and the urban environment, as well as sustainability at the highest and broadest level.

Seven of our projects were named “Best in Category” at the CTBUH’s Tall + Innovation Conference, held virtually from 18 to 20 May. The category winners were chosen from a group of over 160 world-class finalists from over 40 countries.

1 Bligh Street

1 Bligh Street, Sydney, Australia - 10 Year Award

1 Bligh Street, with its spectacular 30-storey atrium, set new standards for sustainability and innovation in high-rise development in Australia. The Arup team provided structural, mechanical, façade and fire engineering and design, as well as building envelope and sustainable building design.

CITIC Tower, Beijing, China - Best Tall Building (400m and above) and Fire & Risk Engineering

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.

Claridge's Hotel

Claridge's Hotel, London, UK - Geotechnical Engineering

Arup and McGee developed a methodology to excavate and construct a five-storey basement under Claridge’s Art Deco wing while the hotel remained fully operational. Arup’s structural and geotechnical engineers, together with our advanced technology and research group, contractor McGee and temporary works designers RKD, spent six months carrying out site trials, material tests and analysis to demonstrate that the concept was buildable. An additional 5,500m² of space was created under the central London hotel with no disturbance to the hotel’s guests.

Hanwha HQ

Hanwha Headquarters, Seoul, Korea - Renovation

Arup provided façade engineering services for the remodelling of the existing Hanwha Headquarters building. We worked closely with the architect to create a façade that was responsive to the site conditions – the ‘eye’ areas are located in the places receiving the most sunlight with the best views. Hanwha’s high-performance PV panels were integrated into the design to highlight the façade aesthetic.

Raffles City Chongqing

Raffles City Chongqing, China - Best Tall Building (300 - 400 meters)

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.

Additionally, we are involved in a total of 13 Audience Awards, selected by the hundreds of conference attendees who participated in the virtual events.

The CTBUH awards aspire to provide a more comprehensive view of these important structures, while advocating for improvements in every aspect of performance, including those that have the greatest positive impact on the individuals who use these buildings and the cities they inhabit. The annual awards are an independent review of new projects, judged by a prestigious panel of experts.
