The four contracts include the design and construction of three JRL stations, signalling system and half-height platform screen doors and integrated supervisory control and communications systems.
Four contracts totalling $682.5 million for three Jurong Region Line (JRL) MRT stations were awarded by The Land Transport Authority (LTA) on 17 July.
The contracts cover the “construction of three JRL stations and their associated viaducts (J109); the provision of the signalling system and half-height platform screen doors (J152); the delivery of an integrated supervisory control system (J155) and the communications system for the JRL (J160)”, revealed LTA in a release.
Worth $320.4 million, the design and construction contract for three JRL stations and their associated viaducts (J109) was awarded to Daewoo Engineering & Construction – Yongnam Engineering & Construction Joint Venture.
LTA noted that the contract “covers the design and construction of Toh Guan, Jurong Town Hall and Pandan Reservoir stations and viaducts spanning 3.6 km”.
The station at Toh Guan will serve existing residential developments located along Jurong East Central, educational institutions like Crest Secondary School and places of worship.
The Jurong Town Hall station will benefit those travelling to and from International Business Park, while the Pandan Reservoir station will serve residents around West Coast Road and Teban Gardens as well as Commonwealth Secondary School and places of worship.
LTA expects construction works for the three stations to start later this year.
“Residents and commuters who use these stations when the JRL is completed can expect to see significant time savings,” it said.

Currently, Daewoo Engineering & Construction is involved in the construction of Stevens station on the Thomson-East Coast Line, while Yongnam Engineering & Construction is involved in the North-South Corridor’s construction as well as the Canberra station on the North-South Line.
Meanwhile, the $215.5 million contract for the provision of the signalling system and half-height platform screen doors (J152) for the JRL is awarded to a consortium between Siemens Mobility Pte. Ltd. and Siemens Rail Automation.
The contract includes “the design, manufacture, supply, installation, testing and commissioning of the signalling system and half-height platform screen doors for the entire JRL”.
Supporting fully-automated train operations, the signalling system will be equipped with condition monitoring capabilities, enabling predictive maintenance over the system’s life cycle.
Siemens’ signalling system is used in “the Downtown Line (DTL) in Singapore and several metros around the world, including the Este in Madrid, the Marmaray Rail Tube Tunnel in Istanbul and the Metro L2 in Changsha,” said LTA.
The third and fourth contracts, which cover the provision of the integrated supervisory control system (ISCS) (J155) and the communications system for the JRL (J160), were awarded to ST Engineering Electronics and totals $146.6 million.
LTA explained that the ISCS is an important part of “efficient rail operations as it provides the basic framework to enable a rail line’s Operation Control Centre, Depot Control Centre and Passenger Service Centre to remotely supervise and control other electrical and mechanical systems and services, as well as civil equipment”.
It added that JRL’s communication system comprises sub-systems like the communications backbone network, video surveillance, public address, digital trunked radio, telephone and travel information systems.
ST Engineering Electronics is presently involved in the implementation of communications systems and ISCS for Circle Line 6 as well as DTL3 extension projects.
