Double Wins at HKIE Structural Excellence Award 2024

Organised by Hong Kong Institution of Engineers (HKIE), the Structural Excellence Award aims at promoting excellence in structural engineering through the design and construction of buildings, infrastructures, research and application.

The achievement exemplifies WSP’s capability in harnessing our structural expertise and delivering innovative and cost-effective solutions to create unique designs that maximise efficiency and sustainability.

Cainiao Smart Gateway
Hong Kong Non-Residential Project – Grand Award

WSP provided structural, geotechnical and civil engineering consultancy services for this one of the largest and most technologically advanced logistic centres in Hong Kong with a total GFA of more than 380,000 sqm spreading over 12 floors at the Hong Kong International Airport.

As the building has a length exceeding 300m, our design featured stiff beam-column frame to control building movement under wind and enhance structural efficiency, and expansion joint was leveraged to reduce thermal stress. Large diameter bored piles with high capacity was utilised to speed up construction, and C80 high strength concrete was used to maximise warehouse storage space due to the heavy gravity load.

To ensure super-flatness and levelness in the warehouse area, we adopted a 75mm late cast wearing slab on top of structural slab redesigned with reduced thickness to minimise load impact on foundation and improve reliability. A repeated floor system was implemented to increase structural standardisation and provide a uniform layout and reduced difficulty in logistic equipment installation.

The Twins
Hong Kong Non-Residential Project – Commendation Merit Award

A commercial development with two 29-storey structures and four-level basement located in two adjoining individual sites in Kai Tak, the project will become one of the iconic landmarks in new development area of Kowloon East.

WSP provided structural, geotechnical, civil, MEP, traffic and façade engineering consultancy services for this multi-functional building. To resolve underground constraints and unsymmetric ground floor conditions while maintaining the aesthetics of twin towers, a two-storey steel mega truss approach was designed to hang part of superstructure in between MEP floors, integrating the truss inside MEP function room without additional restriction of floor usage. Bottom-up method was used to avoid large scale working activities in confined space and minimise the risk by excavation through shorten excavation time, reducing impact to existing sensitive underground structures and other concurrent construction activities in adjacent sites.
