Pipe-jacking in action in a past PUB project at Jalan Buroh by Ley Choon. From the above road area, a boring machine guided the installation of a long pipe underground. This method does not require extensive open-cut construction activities on the road surface.

A 2.1 km long water pipe will be installed from Jalan Kampong Chantek to Dunearn Road but you will not notice any major traffic diversion nor will there be much dust and noise.
The project to be undertaken by SGX Mainboard-listed Ley Choon Group will employ "trenchless technology" which avoids the use of open-cut methods, reducing construction activities on the surface.
Ley Choon Group has gained expertise in "pipe-jacking" after having done many similar projects before.
In this latest project, Ley Choon, a leading one-stop service provider for underground utilities construction and road works, was awarded a S$25 million contract by the Public Utilities Board (PUB).
Expected to be completed in two years, this contract involves the laying and installation of 2.1 km length of a 2.2 m diameter potable water transmission steel pipeline.
The pipe-jacking method involves the use of a remotely controlled pipe-jacking boring machine to guide the entire pipe-jacking process, with most activities done sub-surface.

We are delighted to win another pipe-laying project from PUB, which has been our client for more than 25 years.”
The new pipeline line in this project when completed will improve flow and pressure of water supply servicing residents upstream of city.
Mr Toh added: “Leveraging on our expertise in pipe-jacking and micro-tunnelling, we will continue to tender for more pipe and cable laying projects.”
The Group’s unfulfilled order book based on secured contracts stood at S$186 million as at 31 March 2015, keeping the Group busy with projects for the next two years.
As a L6-registered contractor (the highest grade) with the Building & Construction Authority (BCA), Ley Choon is able to tender for Singapore’s public sector contracts of unlimited value in the categories of cable/pipe-laying and road reinstatement, pipes and other basic construction materials. The Group is also an A1-registered contractor in the category of civil engineering (CW02).
