Before we know it, May has come and gone. Perhaps the month felt a little shorter due to the vacation that some of us took during the month. That said, the heat has been relentless over the past month. We're sure that the contractors on the Jurong Region Line (JRL) would have been feeling that - figuratively & literally. The good news is that there has been a significant amount of promising progress made through the various contracts. We'll take a look at this is slightly greater detail after the jump.

Phase 1
With the clock ticking till the completion of works are due, contractors have been rushing to make headway and meet deadlines. Some trial assemblies of architectural finishes have been implemented at various stations, in addition to the ongoing installation of various utility and electrical systems.

Tengah depot (Contract J101)
In a nutshell: Progress appears to have been made on structural elements of the workshops, including the bus parking structures and various connecting bridges within the depot site. However, it does not appear that any interior fit out works are in progress at the moment. Track laying equipment was seen on site, however the tracks have yet to connect to the lines within the workshop areas.

18 May 2025

JS1 - Choa Chu Kang (Contract J102)
In a nutshell: Roof frame installation over the new platforms continued, with the western-most platforms receiving the frames as well. One section the frame near the northern end of the North-South Line (NSL) platform was also equipped with a trial assembly of the cladding to be used on the edge of the roof. Within the existing NSL station, there were several small additions to the station in preparation of modification works to come. On the viaduct front, parapet wall installation works were ongoing for the few remaining sections which had yet to be completed - one section above Choa Chu Kang Avenue 4 and the over run section north of the station.

31 May 2025

JS2 - Choa Chu Kang West (Contract J102)
In a nutshell: All 6 pairs of diamond-shaped columns to support the roof frame had since been installed. Work to connect the 2 station exits had also taken place, with the podiums reaching the full design height. The next phase of exit podium construction would be for the installation of escalators and lift cars, along with roofing. Parts of the roof insulating layers were also being installed. Additionally, track works had reached the station, with the rails laid till just west of the station. It may be a while before works are able to continue through the station to continue on towards Choa Chu Kang station.

31 May 2025

JS2A - Forest Hill (Contract J102, provisional future station)
In a nutshell: Works at the provisional station structure are largely complete, save for rail installation related works. Nearby, work was underway for the installation of turnout switches, with workers using a gauge meter to ensure the alignment of the tracks were within limits before performing flash butt welding to join the rail sections together.

31 May 2025

JS3 - Tengah (Contract J102)
In a nutshell: Roofing works for the station had progressed with the first layer of protection installed. As part of Tengah Central has since been opened to vehicular traffic, it is now possible to gain a closer look at the station and viaducts from the south. Track laying works were in progress, with the first noise barriers to be installed along the line making an appearance along the reception track linking to the upper level of the station.

25 May 2025

JS4 - Hong Kah (Contract J103)
In a nutshell: This station is likely to be the first through which tracks had been laid, with a locomotive seen on the reception track as it parked within the station. Elsewhere, the exit linked to the station through a connecting bridge was making significant progress with its roofing already installed.

25 May 2025

JS5 - Corporation (Contract J103)
In a nutshell: The station building continued to take shape, with the exit podium on the northern side of the station making headway. With the structural elements in place, work was centred on the roof installation works for the podium and linkbridge. Inside the station, installation works were well underway for the services boom at platform level. Cladding was being installed along with other components such as speakers. Other internal features that could be made out included the installation of High Volume Low Speed (HVLS) fans to ventilate the platform area.

18 May 2025

JS6 - Jurong West (Contract J105)
In a nutshell: External cladding installation works had begun at the station, with cladding panels being affixed to the frame. Unfortunately, we were not able to obtain an image of the external cladding panels installed on the frame this month - we will update on this in the following months' snapshot update. Exit podium works were well underway too.

18 May 2025

JS7 - Bahar Junction (Contract J105)
In a nutshell: Works were commencing on the casting of crosshead beams to support the platform level transfer linkway bridge connection. Casting works were underway for columns supporting the platform level and trackbed at the satellite station building as well.

17 May 2025

24 May 2025

JS8 - Boon Lay (Contract J106)
In a nutshell: The first layer of roofing insulation had been completed, with further layers to be added on subsequently. Preparations for the reinstatement of Jurong West Street 64 beneath the station were being made. Within the existing East-West Line (EWL) station, works were underway to shift the fare line at Exit D further out towards Jurong Point. This will serve to create additional circulation space for the construction of an additional lift within the fare paid area.

17 May 2025

18 May 2025

JW1 - Gek Poh (Contract J107)
In a nutshell: As roof frame installation works continued, escalator components began arriving at the station site. The installation of the protective enclosure also continued to allow future trackworks to take place as roof installation works progress concurrently. With the completion of viaduct segment launching operations, parapet wall installation works were underway.

17 May 2025

JW2 - Tawas (Contract J107)
In a nutshell: Installation of the first layer of roofing insulation had begun. At platform level, the utility service booms had been installed although these were not yet clad with paneling. Works were focused on the construction of staircases and lift cores connecting the concourse level to the platform.

Phase 2
There is a little more breathing room for the phase 2 section of the line, given that this section will only open in the year following the first phase's operation. Nonetheless, construction of the stations in this phase have made significant progress. Presumably, all stations under contract J108 have commenced escalator installation works. Most stations under contract J109 have structurally reached the platform level as well, while Jurong East station has about reached its full design height.

JE1 - Tengah Plantation (Contract J108)
In a nutshell: Similar to Choa Chu Kang West station, this station is designed with 3 sets of escalators between the platform and concourse levels. However, installation works during the initial opening suggest that only 2 escalators will be provided for, with a metal staircase being installed within the pit for the third set. On the viaduct front, 4 spans remain for each bound to be completed by launch gantry Magnificent Mammoth which is anticipated to complete around July.

25 May 2025

JE2 - Tengah Park (Contract J108)
In a nutshell: By far the most advanced among the phase 2 stations, works continued on the station building and nearby viaducts. A future trackworks temporary staging site is located just south of the station and was being prepared for the commencement of track laying works.

25 May 2025

JE3 - Bukit Batok West (Contract J108)
In a nutshell: All 6 diamond-shaped columns supporting the roof were installed at the station. Escalator installation works had also commenced, with at least 2 escalators connecting the concourse and platform levels visible. With only 2 spans of viaduct remaining to be completed, parapet wall installation works have commenced.

31 May 2025

JE4 - Toh Guan (Contract J109)
In a nutshell: With all the concourse level columns cast, formwork was being installed for the casting of the beams that would support the platform slab above. Towards the north of the station, viaduct segment launching works were underway through the balanced cantilevered method. To the south of the station, viaduct pier crosshead construction was well underway, with one of the two portal piers since completed.

31 May 2025

Tracks through Jurong East Integrated Transport Hub (Contract J120)
In a nutshell: The viaduct spans under the contract have mostly been completed and are in position, although the cast in-situ spans through the new Jurong Hub development will need further concrete pouring to build the spans out to the full design specifications. The sections through open air have seen progressive installation of the parapet walls.

31 May 2025

JE5 - Jurong East (Contract J110)
In a nutshell: Columns supporting the station extension's roof have reached the top level above the upper platform. Works were underway for bridging the gap between the existing EWL Westbound track and the new station platform. Towards the end of the month, new fare gates were installed for a new, relocated fareline. Several ticketing kiosks were also relocated ahead of reconfiguration works at the concourse level. Viaduct span construction works saw the connection of the spans to the interfacing section with contract J120.

18 May 2025

31 May 2025

JE6 - Jurong Town Hall (Contract J109)
In a nutshell: The station building structure was substantially completed up to the platform level, with the launch gantry progressing southwards towards the Ayer Rajah Expressway (AYE). No escalators were seen installed as yet, nor any roofing frames installed.

31 May 2025

18 May 2025

JE7 - Pandan Reservoir (Contract J107)
In a nutshell: Parts of the platform level for the station were under construction, with casting works moving southwards. Viaduct span construction was moving slowly from the tail end of the line's viaducts next to Pandan Reservoir.

31 May 2025

Phase 3 (South)
Phase 3's southern section has begun to become more prominent with sections of the viaduct taking shape. However, these are all north of the AYE and the area south of the expressway does not yet have any viaduct sections complete or in the span launching phase. The trend of station construction also follows closely, with stations located north of the AYE making the most progress.

JS9 - Enterprise (Contract J111)
In a nutshell: The station structure was coming together quickly, with works already focusing on the platform and trackbed level. Viaduct construction works on either end of the station building were also taking place at breakneck speed, with several spans since completed. Work on the sharp curve from Jurong Central Park to Jalan Boon Lay was underway, with viaduct segment launching taking place.

24 May 2025

JS10 - Tukang (Contract J111)
In a nutshell: The centre part of the station had begun work on casting of the platform level beams. On either end of the station, casting was underway for the crossheads of the viaduct piers.

24 May 2025

JS11 - Jurong Hill (Contract J112)
In a nutshell: A fourth station pier had since emerged while two others had completed installation of the precast crosshead segments. Viaduct piers just to the north of the station had began to emerge, with crosshead casting following suit.

24 May 2025

JS12 - Jurong Pier (Contract J112)
In a nutshell: Casting work had begun for the station columns on the western side of the station. Diaphragm wall construction continued for the subway linking to an exit located across Jurong Pier Road.

24 May 2025

Phase 3 (North)
In comparison to Phase 3's southern section, the northern sector features a more consistent construction pace. All 3 stations within Nanyang Technological University (NTU) had large portions of structural works completed and significant stretches of viaduct spans launched. None of the 3 stations had yet seen viaduct spans connect to the station buildings directly yet, though. Some amount of works remain till any of the structures will be able to obtain basic structural completion.

JW3 - Nanyang Gateway (Contract J113)
In a nutshell: Following the earlier diversion of Nanyang Drive below the station, work had commenced on foundations for the remaining viaduct piers supporting the Choa Chu Kang-bound track. Casting was also underway for the platform level slab, with rebar for the staircase at the station's eastern end still showing.

24 May 2025

JW4 - Nanyang Crescent (Contract J113)
In a nutshell: The station building had made progress with the entire platform level since built out. Work on the upper concourse level, which would feature linkbridges to 2 exits on either side of Nanyang Drive, was also substantially built. Works continued on viaduct span construction on either side of the station.

24 May 2025

JW5 - Peng Kang Hill (Contract J115A)
In a nutshell: The station structure has since come up, with works now focusing on the platform level slab. Works are more advanced towards the northern end of the station building, where the upper concourse level will be located. Due to the vegetation in the way, we are unfortunately not able to get a clear look at the construction progress in detail. To the north, several viaduct spans have since been completed, with works ongoing for the span across the junction of Nanyang Drive & Nanyang Crescent.
