Happy New Year! We hope that your 2026 will be a bright & incredible year for you. The team was rather busy through 2025, especially during the last few months of the year. We weren't able to compile a Snapshot feature to close the year off for updates on the Jurong Region Line (JRL), but will be working to make one happen for this month's progress. To make up for the lack of a Snapshot update though, here are some images that we've come across that may interest you.

We're moving onto recapping the Q1 2025 progress of contract J102, awarded to Shanghai Tunnel Engineering Co. This contract of the Jurong Region Line (JRL) saw several key milestones being hit this past quarter, including but not limited to completion of viaduct segment launching, the commencement of roof frame installation works at the stations and the installation of escalators within the stations. We'll cover these in greater detail as we look at each station site closer.

Continuing on with our 2024 progress report, we now come to the stations under contract J102. Arguably the largest contract under the Jurong Region Line (JRL), the contract stretches across approximately 4.3km from Choa Chu Kang to Tengah and includes 3 stations. Also included in the contract are the bare bones for a future station within Tengah's northeast sector, which we refer to as Forest Hill, after the Tengah planning district in which it is located.
Progress on the contract has seen several milestones through 2024 which include the handover of the first sections of viaduct to the track works contractor, completion of launch gantry Mulan's viaduct segment launching and the completion of all viaduct piers along the contract. We take a closer look at the various sections in detail after the jump.
Today, contractor for package J102 - Shanghai Tunnel Engineering Co (STEC) - released a progress update on the package's official Telegram channel. The update features aerial views from a drone of the project's progress and all four stations (3 full build & 1 future infill) can be seen in the video. We'll go through some of the coverage from the video and accompanying update on upcoming works that was initially published, but subsequently retracted, as well.

A lot has taken place in Q2 for contract J102. With 4 stations being built under the contract, we had to split this update into 2 parts to make it more bite-sized and not an overload of information or more of a huge photo dump than it already is. Progress has been swift and moving full steam ahead as the changes to the sites can be seen with every visit. Nonetheless, it will still take some time before the Jurong Region Line (JRL) sections under this contract can achieve basic structural completion.

With Q1 of 2024 coming to a close soon, we're beginning our quarterly updates on the Jurong Region Line (JRL). Last week, we covered the progress of Tengah depot over the first quarter, including the commencement of trackworks! Today, we'll dive a little deeper into the works taking place under contract J102 by Shanghai Tunnel Engineering Co which includes 3 stations, approximately 4km of viaducts and a future shell station.

Transformation has taken place over the past quarter at the site of the Jurong Region Line (JRL)'s Choa Chu Kang West station and viaduct sites. Work has commenced on the station concourse slab crossheads which, like many other stations located in the road median, will help to support beams that will form the concourse slab eventually.

A recent post by MP for Keat Hong divison, Mr. Zhulkarnain Abdul Rahim, showed a visit to the Jurong Region Line (JRL) Project Information Centre (PIC) featuring new station architectural models. Our team made a visit to the JRL PIC today to check out the new additions to the collection.

Contract J102 involves the construction of 3 stations along the Jurong Region Line (JRL) and provisions for a future infill station as well. Stretching approximately 4.3km, the second station along the line is located on Choa Chu Kang Avenue 3 and is tentatively called Choa Chu Kang West. We check in on the progress made at the station site as of quarter 2 of 2023.
We launched our new mini-series last week, a deep dive into the process of building an elevated MRT line which was last seen on the East-West Line when the Tuas West Extension was built. Join us as we explore the first of six distinct stages of bringing an elevated MRT line to life - the preparatory works stage.
Recently we came across several render videos for contract J102. The first video shows the renders of Choa Chu Kang, Choa Chu Kang West & Tengah stations which are being built by contractor Shanghai Tunnel Engineering Co (STEC). Subsequent videos show the process of unloading components of the launch gantry at the storage site, assembly & lifting of the launch gantry used for viaduct construction and the construction of the base slab at Choa Chu Kang station.

The stretch along Choa Chu Kang Avenue 3 has been fully diverted allowing for construction works to commence in the road median. As such, foundation works are taking place along the entire stretch of roadway. Several auger machines are dotted throughout the work site to commence bored piling for the pier foundation piles.

Also under contract J102 is neighbouring station Choa Chu Kang West. Located along Choa Chu Kang Avenue 3, works have been on-going to shift the carriageways apart to allow work to commence in the road median. Most of the viaduct piers will be located here, with the exception of a few portal piers (piers that straddle either side of the road and use a horizontal beam in between to support the viaduct). The station will also be located in the road median, offering access to either side of the road via linkbridge - akin to stations like Clementi, Dover, Commonwealth and Queenstown on the East-West Line.

Recently we came across some new renders of the stations along the Jurong Region Line (JRL). We thought it would be fitting to do a re-post of all the renders we've amassed thus far. Do stay tuned as we'll let you know where we got the new renders from after the phase 3 batch.

Its been a while since we caught up to how things are shaping up on the Jurong Region Line (JRL). Things are indeed picking up pace! We've made a few comparisons to how things looked in the past as far as possible. For this post in particular, we'll be covering the stations under contract J102 (Choa Chu Kang, Choa Chu Kang West & Tengah) and also Tengah Park under contract J108.

Work on contract J102 has proceeded swiftly with demolition of Block 303 Choa Chu Kang central commencing in December 2020. A month later and the entire block has been brought down to make way for the new Jurong Region Line (JRL) being added to the station complex. As part of the JRL project, two additional platforms will be constructed at the station, allowing access from the North South Line (NSL) to the JRL.

Since our last update of Contract J102, there has been some progress made. Most visible is the progress around Choa Chu Kang station for site preparation. Scaffolding has been going up around the vacated Block 303 along Choa Chu Kang Avenue 4. A few fabric noise barriers have been installed ahead of the demoltion works.
