The design and construction of One Raffles Quay is widely acknowledged as a major engineering feat due to the constraints of the site and the presence of subway lines at shallow depth running directly beneath its 50-storey North Tower.

Meinhardt pioneered an innovative transfer system utilising the central box core as a transfer structure spanning across the subway tunnels. The unique transfer system along with a highly efficient outrigger braced steelconcrete composite structure and the novel skewing of the building mass over the subway tunnels – to reduce the transfer span – led to enormous cost and time savings on the project. Today, the iconic landmark in the Singapore skyline located in the prime business district encompasses twin office towers with two basements, a multi-level podium, and an underground link to the Raffles Place Mass Rapid Transit Station. It also features Singapore’s first commercially applied District Cooling System, which not only effectively reduces urban heat, but also provides energy cost savings. The North and South Towers, built for banking and financial corporations, add up to an estimated 1.3 million square feet of prime office space. The North Tower stands 50 storeys (245 metres) high, providing outstanding views and column-free space of approximately 18,000 square feet per floor. Standing at 29 storeys (140 metres) tall, the South Tower enjoys large regular column-free space of approximately 30,000 square feet on each floor.
