As it has been approximately 4 years since the Jurong Region Line (JRL)'s final alignment was announced to the public in May 2018, several images of the stations have been made available showing the minor details that distinguish each station from another. Whilst using a basic design skeleton that features a vaulted roof supported along the sides by several columns, each station manages to retain some level of individuality. Several videos have since allowed us to catch a glimpse of the designs of the upcoming stations.

Contract awards - J115A & the curious case of Peng Kang Hill

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.

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.

Contract J102 was one of the first contracts awarded for the construction of the Jurong Region Line (JRL). As such, construction works at this contract are some of the farthest along. The contract entails the construction of 3 JRL stations, including addition & alteration works to the existing Choa Chu Kang station. To do this, a new platform will be added to allow for cross-platform transfer between the North South Line (NSL) and JRL. The concourse level will be expanded as well, to accommodate circulation and vertical access to the new platforms.

CNY Special - First viaduct piers for JRL

 

01 February 2022 - Rebar visible above the hoarding for Jurong Region Line's viaduct piers.

We'd like to wish all our readers a Happy & Prosperous Lunar New Year! May each of you be blessed with bountiful fortune in the year of the Tiger. And to all the contractors on the Jurong Region Line (JRL) project, may you all experience good health (and safety) this coming year.

Through the Chinese New Year period, we have been travelling around a fair bit and noticed the first viaduct piers for the line beginning to emerge above the hoarding protecting the worksite.

To conclude our Q3 update on the Jurong Region Line (JRL) for 2021, we visit Jurong East. Construction here is covered under 2 contracts - J110 and J120. Contract J110 is for the construction of Jurong East interchange station and modifications to integrate the new structure in with the existing complex. On the other hand, Contract J120 involves the construction of the Jurong East integrated transport hub (ITH), including JRL viaducts through the complex.

As our previous post was getting rather long, we decided to split up the updates for easier readability. This section will cover updates on contract J109, the second contract under phase 2 of the Jurong Region Line (JRL). Contract J109 was won by Daewoo - Yongnam joint venture and involves the construction of Toh Guan, Jurong Town Hall & Pandan Reservoir stations. Interestingly this contract is split into 2 sectors located north and south of Jurong East interchange which will be built under a separate contract, being contract J110 won by Daelim.
