Yesterday, the Land Transport Authority (LTA) awarded contract J115A, which includes the construction of Peng Kang Hill station, to Hwa Seng Builder. The successful contractor is also in charge of neighbouring contract J113 for the construction of Nanyang Crescent and Nanyang Gateway stations. As such, this makes all stations within the Nanyang Technological University under the purview of a single contractor - an undoubtedly useful situation as the contractor should be able to ensure that the flow of construction vehicles into and out of the campus can be regulated much more ease than if the contracts were split between 2 different contractors.

Casting Yards

The construction of the Jurong Region Line (JRL) includes the construction of piers and viaducts that will form the trackbed for the line. One of the most common methods for construction of the viaducts is using segmented box girders to form a complete span which is laid between two pier columns. Wires are passed through the interior of the box girders and tensioned, providing the force necessary to keep the span rigid and able to withstand the loads that are placed upon it.
