Amidst all the rain at the end of the year, we bring you the November Jurong Region Line (JRL) snapshot. With work going on round the clock, the various components and structures of the line inch closer to completion. That said, there still is a lot of work to be done as you'll see in this post. More pictures & details after the jump.

Phase 1
This phase is getting there. Sorta? Station buildings are rising, viaducts are forming and then there are some... gaps. Overall, things are progressing. But a lot of catch up work is needed to fill in the missing pieces. More on that in a bit.

Tengah depot (Contract J101)
In a nutshell: With the J151 trains expected to begin arriving from Q1 2025, will the depot facilities be ready in time to receive the trains? Chances are, the depot will not. It is likely that the trains will first head to the Singapore Rail Testing Centre (SRTC) in Tuas for testing locally while work continues to speed up the works at the depot. There has been some noticeable progress for sure. The admin building, located near the depot access gate, has reached level 4. Further back, part of the rolling stock workshop has received its roof, which will double up as bus parking lots. To the left of the rolling stock workshop, more portions of the depot test track can be seen installed as well.

JS1 - Choa Chu Kang (Contract J102)
In a nutshell: Through the month the various viaduct piers south of the station have taken shape, with some beginning the segmental box girder launching. In this section, only one set of piers remains to be cast. At the northern end, near Choa Chu Kang Loop, viaduct segments have also begun launching works. At the station itself, several stores have since vacated the interim shops area, leaving the food stalls as one of the sole surviving shops occupying the last unit in the row. With the first phase of alteration works completed at the existing North-South Line station, shop units here have begun to be displayed on Stellar Lifestyle's website - the leasing arm of SMRT. It will be a matter of time before these units are eventually leased out. The works at the eastern side of the station fronting Lot One have seen the toilets relocated from the interim shop block here as well.

27 November 2024

JS2 - Choa Chu Kang West (Contract J102)
In a nutshell: Works at the station along Choa Chu Kang Avenue 3 have begun on the plant room facilities on either end at platform level. Other components such as the lift shafts have also been installed. At most other stations thus far, the installation of lift shafts has been followed by roof frame installation. On either side of the station, viaduct construction works continue. Recently, launch gantry Mulan completed its work having launched segments for a total of 81 spans. The gantry will backtrack into Tengah where it will be disassembled for use at its next project. Over on the other side of the station, to the east, viaduct construction was ongoing at the junction with Choa Chu Kang Way. Here, the viaduct had almost formed a complete span across the roadway with approximately 1 segment left to be hoisted into place.

22 November 2024

JS2A - Forest Hill (Contract J102, provisional future station)
In a nutshell: Near the future station site, parapet wall installation works had progressed with cable brackets also being installed. Next to the casting yard, a shed for upcoming trackworks could also be seen as the site is readied for handover to the incoming contractor.

25 November 2024

JS3 - Tengah (Contract J102)
In a nutshell: The plant rooms at the upper platform level have taken shape, although it does not appear that roof frame installation works have commenced just yet. Launch gantry Gaia can also be seen just behind the station and may also be dismantled upon completion of viaduct segment launching works.

17 November 2024

JS4 - Hong Kah (Contract J103)
In a nutshell: All 7 pairs of V-columns that will support the barrel vaulted roof of the station have been installed and the majority of the roof frame fixed in place. Only small sections at the ends of the roof remain to be completed. With the frame covering the majority of the station's platforms, additional layers are being added to the roof for weather protection and insulation. Viaducts to the south of the station were in the midst of being built, with several viaduct piers awaiting the construction of viaduct spans atop.

17 November 2024

Reception tracks & Viaducts between JS4 and JS5 stations (Contract J103)
In a nutshell: Steady progress has been observed for the western reception tracks connecting the depot with Corporation station. On the other hand, the eastern reception tracks still feature large gaps where viaduct piers still need to be constructed. The main line viaduct between Hong Kah (JS4) and Corporation (JS5) stations was also not faring much better. Viaduct segment launching recently began in the median of the Pan Island Expressway as the line bisects the roadway. It is likely that this section will still require some time to complete and may become a bottleneck in the line's successful completion.

17 November 2024

JS5 - Corporation (Contract J103)
In a nutshell: As of November, this station is likely to be among the most advanced along the JRL. As the first station to have begun roof frame installation works, the curved end sections of the roof have since been installed. Work was also progressing on the station exits with concrete being poured into the formwork for the exit near Jurong Spring estate.

25 November 2024

JS6 - Jurong West (Contract J105)
In a nutshell: Another station that has made significant advancement is Jurong West station. Most of the exterior roof has been installed, with work now taking place within the station as well. Pieces of the roof's architectural finishings could be seen being installed by a hardworking crew. Viaduct segment launching works also continued to complete the section of viaduct linking to Bahar Junction station.

24 November 2024

25 November 2024

JS7 - Bahar Junction (Contract J105)
In a nutshell: The main station building for Bahar Junction station has had its roof frame installed and parts of the roof have also gone in. Work still continues on constructing the viaducts in the vicinity of the station on either end. The satellite section of the station that will serve trains towards Peng Kang Hill was focused on bridging the gap between the two rows of segmental box girders. Work on the linkbridge connecting the two station buildings together has been progressing with further sections taking shape.

25 November 2024

JS8 - Boon Lay (Contract J106)
In a nutshell: Work on the four storey station has steadily climbed upwards, with works bridging the gap above the existing East-West Line (EWL) viaducts and connecting the two formerly separate halves of the JRL station. As the upper concourse level had been completed, works focused on the platform level and trackbeds. Additional segments of the roof frame were on site waiting to be installed. North of the station, viaduct construction is nearly complete with only a few gaps remaining. Sections of the viaduct towards the north have had parapet walls installed. On the southern side of the station, all spans of the viaduct have been completed but none of the spans have had parapet walls installed yet.

24 November 2024

25 November 2024

JW1 - Gek Poh (Contract J107)
In a nutshell: Construction of the station's trackbed and platform level arms was moving from the north towards the south. Precast T-shaped beams were being installed to support the trackbed while the arms are formed by precast segments with additional concrete poured in to complete the supporting arm. Viaducts to the north of the station were largely completed while those towards the south of the station were progressively being completed.

24 November 2024

JW2 - Tawas (Contract J107)
In a nutshell: At the southern end of the station, the columns supporting the roof frame have begun installation works as the platform level is progressively cast northwards. With segment launching on the southern side of the Pan Island Expressway completed, works have begun on the northern side to bridge the remaining gap.

Phase 2
The second phase of the line is hot on the heels of the first phase of the line with several milestones being accomplished this month. These include the progress of roof frame installation at the first phase 2 station, the assembly of the last concourse level crosshead formwork for one of the stations and the commencement of viaduct pier crossheads at the end of the line. More details in the section below.

JE1 - Tengah Plantation (Contract J108)
In a nutshell: Viaduct construction works have hit a pause recently while the station is fit out with additional load bearing supports to bear the weight of launch gantry Magnificent Mammoth as it will eventually crawl through the station before continuing its journey on the western side of the station. Near the station building, sections of the roof frame have been delivered to the site, awaiting installation once the gantry has launched the remaining spans connecting the viaduct to the station on its eastern station.

23 November 2024

JE2 - Tengah Park (Contract J108)
In a nutshell: The roof frame of the station has nearly been completely installed, with all 6 diamond-shaped supports attached to the sides of the station structure. Near the station, piers for the linkbridge connecting to an exit across Bukit Batok Road have begun taking shape. Next to the electrical substation along Tengah's Plantation Crescent, an intake substation was taking shape.

JE3 - Bukit Batok West (Contract J108)
In a nutshell: With casting works completed for the concourse level slab connecting 8 of the 10 station pier columns. At the western end, works have also begun on the casting of the platform level slab. To the east of the station, launch gantry Rock Steady has yet to be lifted to continue viaduct segment launching works at the contract boundary with neighbouring contract J109.

17 November 2024

JE4 - Toh Guan (Contract J109)
In a nutshell: This month, the formwork for the final concourse level pier crosshead was installed. Following this, casting works can begin in earnest for the concourse level of the station building. Viaduct works on either side of the station were well underway, with works to the north at a more advanced stage. This month, the lifting frame that would assist with launching of viaduct segmental boxes was lifted onto the viaduct pier in the median of the Pan Island Expressway. South of the station, viaduct piers were still under construction with the pier caps being constructed between the station and the Jurong East crossing.

Tracks through Jurong East Integrated Transport Hub (Contract J120)
In a nutshell: Works on the viaduct section through the Jurong East Integrated Transport Hub have taken shape as more of the viaduct spans have been cast. As a section of the viaduct runs through the Jurong Hub building, works have begun on the casting of the support structures for the level 8 slab of the building that will sit above the viaduct.

17 November 2024

JE5 - Jurong East (Contract J110)
In a nutshell: The majority of the works at the station building were focused on the lower platform level. However, some works towards the middle of the station were beginning on the installation of scaffolding to support the casting of beams supporting the upper platform level. Viaduct piers on either side of the station building had also taken shape with casting for the pier columns, crowns and crossheads at various stages of completion. The transfer hub which will link all platforms at the western end of the station was also making progress with several columns reaching up to the concourse level already cast.

17 November 2024

23 November 2024

JE6 - Jurong Town Hall (Contract J109)
In a nutshell: Progress was making headway over at Jurong Town Hall station, with the northern part of the station working on the platform level of the 3 storey station. The Tengah-bound viaduct had completed viaduct spans connecting to the station at this end too. Towards the end of the month, the launch gantry had made a switch back to begin launching viaduct segments on the Pandan Reservoir-bound trackway too. To the south of the station, falsework was being installed ahead of the casting of viaduct pier crossheads. Closer to Jurong East station, work was ongoing for the foundations of several viaduct piers while at least one pair was focused on the beginning of pier column construction.

24 November 2024

JE7 - Pandan Reservoir (Contract J109)
In a nutshell: The majority of the station building's construction had reached the mezzanine level of the 4 storey station. Several columns extending up to the concourse level could also be seen. Casting work had also begun for the viaduct pier crossheads near the end of the line, including that apparently featuring a turnout towards the reservoir, presumably for some future purpose. There were still pockets of sections where construction of the viaduct piers was still focused on the pier foundations as bored piling works were still under way.

17 November 2024

Phase 3 (South)
The southern section of phase 3 might be the slowest progressing of all sections of the line. That said, works are not stagnating or at a standstill, as evidenced by the station and viaduct structures slowly taking shape with each passing month. It just so happens, that when compared to other sections, this appears to be the slowest moving.

JS9 - Enterprise (Contract J111)
In a nutshell: The station building structure is beginning to take shape with about 60% of the concourse slab cast. This station in particular, features a smaller footprint compared to some of the other JRL stations. While the station features 3 exits, connections between the concourse and platform levels will only see a single pair of escalators, a single set of staircase and a pair of lifts being catered for. This is in contrast to other stations which may see 3 or 4 escalators being built from the onset. Elsewhere, viaduct construction works were progressing, especially near the contract boundary with contract J106. The method of construction used for the Jurong River crossing is not often seen in elevated rail construction projects locally as of late - the balanced cantilevered method employing the use of travelling forms. This is essentially a hybrid of the cast in-situ and balanced cantilevered forms of construction that takes a longer time to complete than using precast segmental box girders.

24 November 2024

JS10 - Tukang (Contract J111)
In a nutshell: Tukang station has seen marginal progress since our last visit to the site, with scaffolding and formwork set up for the casting of the concourse level crossheads. Near the contract boundary, a lone viaduct pier was working its way towards crosshead construction. This pier has likely made headway as it is probably a movement & expansion joint pier, which would need to be handed over to southern neighbour contract J112 for viaduct span construction works.

24 November 2024

JS11 - Jurong Hill (Contract J112)
In a nutshell: The station building still consisted of 3 station piers in the road median of Jurong Pier Road. Apart from the three piers at the station site, there is not a lot of other visible structures as yet. However, across the Ayer Rajah Expressway, one of the two viaduct piers had completed crosshead casting works. A hanger beam could be seen installed atop of the crosshead, indicating that the start of viaduct segment launching works is imminent for the contract. A second pier further behind was undergoing crosshead casting works.

24 November 2024

JS12 - Jurong Pier (Contract J112)
In a nutshell: Works along this section of the contract were mainly focused on the station building, with no viaduct pier works seen as yet. There remains a long way to go as no bored piling works for the viaduct sections have commenced to date. Nonetheless, the station building has seen some progress with the low wall being cast along the station's western edge. This will ultimately form the concourse level which will sit slightly raised above ground level.

24 November 2024

Phase 3 (North)
The final section of phase 3 has seen quite some progress since our last visit. More viaduct columns have begun popping up, station building construction has progressed with more columns being cast and viaduct pier crossheads were being unveiled. We wrap up this month's snapshot with the last few stations on the line.

JW3 - Nanyang Gateway (Contract J113)
In a nutshell: Works have begun on the station's concourse level columns, with casting underway for a mix of square-shaped and cylindrical-shaped columns. These will aid in supporting the platform level above. Several more viaduct piers, especially those in the vicinity of the School of Design, Art & Media, had begun sporting completed crossheads with segment launching commencing.

24 November 2024

JW4 - Nanyang Crescent (Contract J113)
In a nutshell: Columns have emerged at the station building site, across the lower concourse and platform levels. Scaffolding and formwork were in place to facilitate the casting of horizontal beams and other supporting columns through the station site.

24 November 2024

JW5 - Peng Kang Hill (Contract J115A)
In a nutshell: Newly cast viaduct columns could be seen to the south of the station building, while those north of the station building began unveiling completely cast crossheads. Most of the station building itself still consisted of rebar with the structure of the station yet to be cast. Immediately north of the station building, columns supporting the embankment upon which a crossover will be located had been further lengthened.

24 November 2024

Overall, November has been a busy month for the contractors working to deliver the JRL. In spite of the challenges brought about by the northeast monsoon season, the teams were pushing ahead with construction of the various pieces of rail infrastructure. Till our next update, we hope that this consolidated summary has given you a glimpse at the progress made through November 2024.

A similar but consolidated (a.k.a. simplified) post will be available on Instagram & Facebook on 30 November 2024.
