The contract covers the construction of a diaphragm wall and bored and secant piles. The piling works, which make up the largest element of the contract, will be undertaken by Keller subsidiary Resource Piling. The company, which Keller acquired in 2009 which will install more than 2,500 piles of varying diameters.
The overall project, for the Singapore Ministry of Health, will create an integrated general hospital, community hospital and specialist outpatient facilities, catering for more than 700,000 residents in the region.
Keller chief executive Justin Atkinson said: "This is the largest contract award to date for Resource Piling. It is a good example of how the businesses we acquire are able, over time, to take on larger and more complex work, knowing they have the technical and financial backing of a strong, international parent.
“Increasing our participation in major projects remains one of our key aims and we are delighted to have been selected to work at Sengkang."
Keller's work is expected to begin next month and to complete in the third quarter of 2014.
