Singapore’s first 50-storey public housing project, the Pinnacle@Duxton, has been recognised by the Institution of Engineers Singapore (IES) as one of the top 50 engineering achievements here.

“The Pinnacle@Duxton, located where the first two HDB rental blocks were built in the area in 1963, represents Singapore’s progress in public housing and home ownership over the last 50 years,” said the Housing and Development Board (HDB).

The project comprises seven residential blocks that are linked together by 12 continuous skybridges, creating possibly the longest sky gardens in public housing history at 400m.

In fact, the sky gardens on the 26th storey also come with an 800m jogging track.

“At over 350 tonnes, the heaviest sky bridge is close to the weight of a Boeing 747 aircraft, and was an engineering feat to assemble high above ground,” noted the HDB.

It revealed that the towering residential blocks were built using high strength concrete, with prefabrication accounting for 85 percent of the construction.

Aside from the Pinnacle@Duxton, two other HDB projects were recognised – My Waterway@Punggol, the first man-made waterway designed as part of the landscape feature in HDB estates, and the Lift Upgrading Programme (LUP), which brought direct lift access to residents, island wide.

Prime Minister Lee Hsien Loong, who officiated at the IES Golden Jubilee Gala Dinner on Friday (1 July), presented the Engineering Feats @ IES-SG50 award to the HDB.

The national competition aims to recognise the top 50 engineering achievements that have made the greatest economic, infrastructural or societal impact on Singapore since 1965.
