A happy new year to everyone! We're glad to be back and kicking off the new year with a snapshot update on all the happenings along the Jurong Region Line (JRL) in the first month of the year. What progress has been made since end-2024? Are there any new developments of note? All these and more after the jump!

Phase 1
Since our last update at the end of the last year, there's been some significant progress made! The workshop building at the depot has had its roof slabbed over (finally!), roofing works were gearing up at Choa Chu Kang and trackwork equipment spotted on the viaducts in Tengah. Elsewhere, viaduct construction works were also being completed and the gaps between piers closed up.

Tengah depot (Contract J101)
In a nutshell: Things have picked up with the workshop building finally having its roof slab decked over. The administrative building, which will house the Operations Control Centre (OCC) & Depot Control Centre (DCC), has also progressed well with parts of the walls on the lower floors being put in. The track ramp connecting the depot with the reception tracks has also been fit out with the parapet walls and cable brackets ahead of trackworks installation.

25 January 2025

JS1 - Choa Chu Kang (Contract J102)
In a nutshell: Preparation work was underway ahead of the station's roof frame installation. As part of these works, steel columns to support the roof along with falsework to support the installation was installed at platform and trackbed levels. Escalators were also installed within the JRL section of the station. Further along, segmental box girder installation works had made significant progress at the crossover deck, with only a few remaining viaduct box segments to be launched. Following this, construction can progress on the construction of the slab connecting the various viaduct spans together.

25 January 2025

27 January 2025

JS2 - Choa Chu Kang West (Contract J102)
In a nutshell: Two of the station's three escalators connecting the concourse and platform levels had since been installed, covered in yellow tarpaulin. Further parts for the third escalator were already on site, awaiting installation. Judging from the hard helmets worn by workers around the site, the escalators are likely to be provided by French firm CNIM, which had previously provided escalators for the Downtown Line. The majority of the viaduct spans in the vicinity have been completed, save for a few gaps here and there. Additionally, all viaduct piers along Choa Chu Kang Avenue 3 had been completed.

27 January 2025

JS2A - Forest Hill (Contract J102, provisional future station)
In a nutshell: The entire shell structure for the future station along the Choa Chu Kang-bound track can now be clearly seen. With the good view of the shell structure, we were able to see that cable bracket installation as part of viaduct preparation works for handover have progressed well. With works at the contract J102 casting yard ramping down, works to convert part of the adjacent area into a trackworks temporary staging area (TSA) had ramped up as construction moves into another phase.

27 January 2025

JS3 - Tengah (Contract J102)
In a nutshell: Roof frame installation works had begun this month with the first set of support columns and connecting arch installed. Further south, along portions of the viaduct handed over to the trackworks contractor, equipment and signage was seen along the viaducts ahead of full scale rail installation works.

25 January 2025

JS4 - Hong Kah (Contract J103)
In a nutshell: Work was progressing on the construction of the linkbridge connecting to the station exit across Tengah Garden Avenue. The exit itself has taken shape, with installation of posts for the exit's roof already installed.

25 January 2025

JS5 - Corporation (Contract J103)
In a nutshell: The first escalator has been installed at the station, connecting the concourse and platform levels at the station's eastern end. Roofing was also being installed along the linkbridge connecting to the first exit structure completed, along the westbound lanes of Jurong West Avenue 2. A further two exits were still under construction at the northern side of the station. Electrical installation works were still ongoing within the station.

25 January 2025

JS6 - Jurong West (Contract J105)
In a nutshell: Work had progressed within the station on the ceiling, however the utility booms at platform level had yet to be installed. Signage, train arrival information systems, speakers and lighting will be hung from these booms, making them an essential feature of the station. Work continued to progress on the wall construction for various back of house rooms within the station at platform and concourse levels. To the east of the station, several gaps still remained in the viaduct spans to be completed. On the western end, however, viaduct span construction had been completed with works moving onto preparation work ahead of the eventual handover to the trackworks contractor.

25 January 2025

JS7 - Bahar Junction (Contract J105)
In a nutshell: Ever a hive of activity, works progress at Bahar Junction station saw the completion of another viaduct span for the Boon Lay/Jurong Pier-bound track as it made the 90-degree turn southwards. The Choa Chu Kang-bound track also finally connected with the main station building. Works were also progressing along the link bridge, connecting the main and satellite station buildings together. The satellite station building still requires the concourse level slab to be completed before the structure can progress further upwards.

25 January 2025

JS8 - Boon Lay (Contract J106)
In a nutshell: Two-thirds of the station's roof frame has since been installed, from the initial 2 pairs of V-columns seen at the end of 2024. Three of the station's new exits were also beginning to take shape, with the fourth outside Jurong Point mall not yet quite there. Also beginning to become rather visible was the paid transfer link between the JRL station's concourse and the East-West Line's platform level. With the viaduct span construction completed for the contract - the first along the JRL to achieve this milestone - works had since focused onto the preparation of the viaduct spans for trackwork installation.

25 January 2025

JW1 - Gek Poh (Contract J107)
In a nutshell: All the precast beams for the trackbed had been completely installed while platform beam installation was ongoing, progressing further southwards. At the northern end, the final viaduct segmental box girders were installed, to connect the station with the existing viaduct spans. South of the station building, viaduct span construction was still ongoing with several gaps remaining before the viaduct spans were fully completed.

25 January 2025

JW2 - Tawas (Contract J107)
In a nutshell: Station roof frame installation works were approximately half completed. Work had begun on the construction of staircases connecting the concourse level with the platform level. Just south of the station, viaduct construction was ongoing at the special crossing over the Pan Island Expressway (PIE). To the north of the station, viaduct works had moved onto the preparatory works for handover to the trackworks contractor. One of the trackworks TSAs will be located across the PIE from the station, on the site of the former Pioneer Primary School.

25 January 2025

Phase 2
Work under phase 2 of the line has been picking up some speed, with 4 launch gantries now in operation. Contract J108's stations had all commenced work on the roof installation, whereas stations under the remaining 2 contracts were in different phases of construction.

JE1 - Tengah Plantation (Contract J108)
In a nutshell: The station building was finally connected to the viaduct spans on its eastern end and the launch gantry was about to transit through the station building. Diamond-shape columns to support the roof frame were installed, but the connecting arches were not installed yet, pending the crossing of the launch gantry through the station. 14 spans remain to be constructed on the western end of the station, where it will link up with viaduct spans completed by contract J102.

25 January 2025

JE2 - Tengah Park (Contract J108)
In a nutshell: The entire roof frame for the station has been installed, with the actual pieces of the roofing system now going in. A linkbridge connecting to the station's exit across Bukit Batok Road has been partially installed across the northbound carriageway too. Works were ongoing for the remaining structure of the exit before the final third of the linkbridge can be installed above the southbound carriageway. Just south of the station, site preparation for a trackworks TSA were in progress as well.

25 January 2025

27 January 2025

JE3 - Bukit Batok West (Contract J108)
In a nutshell: Progress at the station site has caught up somewhat, to that of Tengah Plantation's. 2 diamond columns for the roof structure have been installed on the northern edge of the station while a linkbridge connecting to the station exit across the PIE has been 2/3s installed. It is likely that the remainder of the linkbridge will be installed before the rest of the linkbridge at Tengah Park station is completed. Viaduct span construction was also underway and making progress with launch gantry Rock Steady commencing segment lifting following its repositioning at the interface area with contract J109.

27 January 2025

JE4 - Toh Guan (Contract J109)
In a nutshell: All the station's concourse level crossheads had since been completely cast, allowing for works to take place at concourse level and out of traffic's way. Precast beams were mostly installed for most of the station's length, after which precast decking is laid on top. A final layer of concrete is then pumped over to create the concourse slab. Certain features such as the escalator and elevator pits can be made out. On the viaduct span construction front, work to launch the segments in the PIE median had completed. Work would now begin on the approaches on either side of the expressway. Along Jurong East Central, viaduct piers were at different stages of construction with piers north of the station having crossheads constructed while those south of the station were still working on the pier columns.

27 January 2025

Tracks through Jurong East Integrated Transport Hub (Contract J120)
In a nutshell: Work was mostly focused on the construction of the Integrated Transport Hub (ITH) building deck at level 8, above the split level viaducts approaching Jurong East station. This deck utilizes precast beams installed on columns integrated to the viaduct piers before a concrete deck is cast above the beams. The initial segments of parapet wall installed still remain as is, with no further progress on their installation since they first went up.

29 January 2025

JE5 - Jurong East (Contract J110)
In a nutshell: The majority of the station building has since reached the upper platform level, with the eastern end slowly catching up. At the station's interior, work was progressed with the unveiling of the connection points for repositioned fare gates near the JEM exit. One of the split level viaduct piers at the station's western end had commenced viaduct segment installation works using the balanced cantilevered method.

27 January 2025

JE6 - Jurong Town Hall (Contract J109)
In a nutshell: Approximately half of the station had the platform level structures cast, with work moving progressively southwards. The launch gantry along Jurong Town Hall road, the first under contract J109, had also made significant progress with 9 spans completed and construction of the 10th about to begin. The gantry is likely to construct at least 16 spans on this section of the viaduct. South of the station, viaduct piers were beginning to have their crossheads cast as well, in preparation for segment launching works.

29 January 2025

JE7 - Pandan Reservoir (Contract J107)
In a nutshell: The station was taking shape with works progressing on the northern end and the station structure reaching the concourse level. Works on the final level - the platform - had yet to begin. Viaduct piers in the immediate vicinity of the station building were only completed up to the crown level, with no crossheads in place yet. Towards the end of the line, however, crossheads could be found aplenty along with the contract's second launch gantry. With the gantry in place, construction works had begun on the first viaduct span.

29 January 2025

Phase 3 (South)
The southern part of phase 3 was finally showing some significant progress as station buildings began to take shape. When compared to the northern part of the phase, works in this section are a little slower, potentially owing to the more varied terrain and structures required.

JS9 - Enterprise (Contract J111)
In a nutshell: The station had completed construction of the concourse level with all beams and decking mostly complete. Work would likely be progressing on to the platform level. Several spans of viaduct had been completed just north of the station, while the first few spans were beginning to take shape on the southern end. Recently, several road closures were initiated to allow the falsework for the construction of a portal beam across Jalan Boon Lay to be installed. Work on this portal pier is still ongoing with concrete pouring yet to take place. Viaduct span construction with the form travelers towards Boon Lay station was progressing well, with the spans nearly completed. Likewise, viaduct span construction along Jurong West Street 64, where the viaduct links up with neighbouring contract J106, was nearly completed with approximately 2 spans remaining to the completion of the viaduct. Work was underway for the construction of a trestle structure to facilitate segment launching.

25 January 2025

JS10 - Tukang (Contract J111)
In a nutshell: All 9 of the station pier columns had been completed, with 5 also receiving the concourse level crossheads. It appears that the stations located within Jurong Industrial Estate will be slightly smaller than those along the rest of the JRL, employing only 9 station piers over the typical 10. The final viaduct pier along the contract at the south, the interface with neighbouring contract J112, had been completed with the movement & expansion joint crosshead completed. However, the pier had not been handed over to J112's contractor yet, for viaduct interfacing works.

25 January 2025

JS11 - Jurong Hill (Contract J112)
In a nutshell: About 1/3 of the station's pier columns were completed with works to launch pre-cast concourse level crosshead beams underway for the first of these piers. A further remaining 6 piers would need to be completed before works on the station could progress in full. It is likely that these further piers would take more time, owing to the inclusion of the vehicular underpass works as part of the contract, which sits directly beneath the station necessitating the integration of the station structure with the depressed road ramp to the underpass. At the northern end of the contract, the first few viaduct piers had taken shape with crossheads in place. Viaduct segment launching works were underway.

25 January 2025

JS12 - Jurong Pier (Contract J112)
In a nutshell: A hydrofraise machine could now be seen on site, to facilitate the diaphragm wall construction of the underground portion of the station. Initially, this would be relegated to the subway underneath Jurong Pier Road connecting to a station exit. Ultimately though, the station will be integrated with the future Cross Island Line station box, necessitating underground paid transfer links as well. The station structure remains largely the same, with only the low wall nearest to Jurong Pier Road seeming to have progressed further. To date, no viaduct pier construction works have taken place with a lot of the utility diversion works taking place to prepare the sites for the bored pile construction first. Segmental box girders could be seen stored near the station site, likely to support ongoing viaduct span construction near Tukang station.

25 January 2025

Phase 3 (North)
The final phase of the line within Nanyang Technological University has seen more advances in construction than its southern cousin. Station structures for all three stations could be seen making significant progress and viaduct span construction likewise continued.

JW3 - Nanyang Gateway (Contract J113)
In a nutshell: Works on the station structure had begun to approach the platform level, with beams supporting the platform and trackbed being cast. Connecting beams will be cast here for the trackbed and platform level slab. Viaduct construction had progressed with the gaps between piers gradualling reducing. In time to come, Nanyang Drive is likely to be relocated directly beneath the station structure, to allow for the remaining viaduct piers of the Choa Chu Kang-bound track to be built.

29 January 2025

JW4 - Nanyang Crescent (Contract J113)
In a nutshell: Being built into a hillside, the station presents a unique layout consisting of 3 levels. Works had progressed to the upper concourse level, the highest level of the station. Precast beams for the level had been installed, before subsequently being decked over.

29 January 2025

JW5 - Peng Kang Hill (Contract J115A)
In a nutshell: Similar to Nanyang Crescent station, this station features 3 levels with the platform level sandwiched between two concourse levels on either end of the station. The structure of the station had begun to become more apparent with several columns being visible. Viaduct piers to the south of the station had been cast to the crown level, with further casting for the pier crossheads to follow. Directly north of the station, the crossover switch deck had made decent progress with the first section of the deck cast. It was possible to see the stubs indicating the location of the future tracks for the line. Beyond the crossover deck, viaduct segment launching works had begun from one of the viaduct piers.

All in all, January has been a busy month for the line. Much of the progress can be seen with escalators and station roof frames being installed. We look forward to additional milestones being achieved this year - such as the delivery of the first J151 trains within the first half of the year and the laying of the first sections of rail along the viaduct. Do stay tuned as we bring you more JRL updates in time to come!

A similar but consolidated (a.k.a. simplified) post will be available on Instagram & Facebook on 1 February 2025.
