Appointed directly by the Hong Kong International Airport Authority (HKIAA) working closely with AECOM, Design4Structures were commissioned to deliver both engineering and construction modelling services. This meant that the Tekla model creation and development would run concurrently with the structural design.
HKIAA, approached us, to explore a digital asset-led approach to the construction of the enormous roof structure as part of its Terminal 2 expansion. This meant bringing the 3D modelling and detailing element much earlier in the project delivery. This was developed alongside a team of Structural Engineers, who designed a set of complex connections for the structure, assisting also with the rafter and bracing in the roof and the heavily loaded tree structure supporting it.
The roof structure was formed of 11.750t of steelwork, with over 30,000 steel assemblies and 16 waveform trusses at 223m in length. The building measures over 270m in length and 230m in width.
By investing in our project delivery method, the airport authority could de-risk by identifying any potential issues at the front end of the design process, before the construction programme was compiled – this enabled more accurate timescale predictions, reduced delays and no unexpected additional costs. The project demonstrates an inspiring change in the way that projects can, and will, be procured in the future.
