Singapore has announced that they will build a polder designed by Royal HaskoningDHV with local partner Surbana Jurong that will add 810ha to Pulau Tekong, one of Singapore’s largest islands.
Traditionally, sand has been used to fill the area to be reclaimed above sea level. The new approach involves building a dike around the area to be reclaimed and draining the water from it – a 400 year old Dutch proven method.
This will allow the reclaimed area to be built at a lower level and hence significantly reduce the amount of sand needed for land reclamation.
Royal HaskoningDHV and local consultancy Surbana Jurong carried out the detailed study and engineering design with Singapore’s Housing & Development Board for this development located in the northeast of Singapore.
The studies and design were carried out together with Professor Kees d’Angremond as an expert adviser and Deltares as a Specialist Consultant.
Demand for sand
Mark van Zanten, Senior Project Manager at Royal HaskoningDHV, said: “We’re proud to help build the future of Singapore. The polder approach has been used in the Netherlands for many centuries, but is still in its infancy in Southeast Asia and the rest of the world.”
“This approach significantly reduces the volume of sand required as compared to the traditional method of land reclamation, and will ultimately result in savings on upfront construction costs.”
Rising sea levels
Mr Loh Yan Hui, Deputy CEO for Infrastructure, Surbana Jurong, added: “Innovative and cost effective reclamation solutions are needed to help countries tackle the challenge of rising sea levels as a result of global warming.”
“This partnership with Royal HaskoningDHV is the first of its kind in this region. Royal HaskoningDHV’s global experience in polder reclamation combined with Surbana Jurong’s coastal engineering experience and knowledge of the local environment in Asia puts us in a unique position to offer innovative and cost effective reclamation solutions to clients in Singapore and the region.”
This project is estimated to begin at the end of 2017 and complete in 2022.
