2024 is the halfway mark in construction for the Jurong Region Line (JRL)'s first phase. Works across the various stations reached significant milestones with several stations now working on the metal roof frames. Discover the progress made through mid-September after the jump.

Phase 1
Naturally being part of the first phase means that you make the most progress. This can be seen through the various stations along this phase having roofing and platform plant room works commence. Despite all this awesome progress though, there are still some sections where viaduct progress requires a fair bit of catch up work.

Tengah depot (Contract J101)
In a nutshell: There is progress overall, with several new tower cranes assembled at the site of the multi-storey bus park facility recently. Along the reception track ramp, parapet wall installation has begun. Over at the workshop facility, longitudinal beams have begun installation as well. This will serve as additional bus parking lots at the roof level. Track installation works continue through the limited areas where such works can proceed.

15 September 2024

JS1 - Choa Chu Kang (Contract J102)
In a nutshell: The new station building has seen portions of the new North-South Line (NSL) platform cast along the centre section. Plant rooms at the ends of the platform were also being constructed. The biggest changes seen within the existing station include the relocation of the fare line towards Exits A and B along with the shut down of the former up-riding escalator. The new concourse-to-platform link has opened on the northern end of the station allowing station modification works to proceed to phase 2.

15 September 2024

JS2 - Choa Chu Kang West (Contract J102)
In a nutshell: The corbel structures at the station have since been completed, ready to link the station up with the viaduct spans when construction proceeds closer to the station building. Works are focused on the underplatform level at the station currently. Further along Choa Chu Kang Avenue 3, viaduct span construction works are underway at various locations.

14 September 2024

JS2A - Forest Hill (Contract J102, provisional future station)
In a nutshell: Parapet wall installation is completed for a continuous stretch from the station's shell structure up to where the separate viaduct box structures meet. Launch gantry Mulan had successfully crossed over Brickland Road and had begun viaduct span construction along Choa Chu Kang Avenue 3 towards Sunshine Place shopping centre. As of the middle of the month, three spans had been completed since the gantry made the move into Choa Chu Kang town.

14 September 2024

JS3 - Tengah (Contract J102)
In a nutshell: With launch gantry Gaia having cleared the station to construct the viaduct spans on the northeastern side of the station, work began on construction of the plant room at the upper platform level of the station.

15 September 2024

JS4 - Hong Kah (Contract J103)
In a nutshell: With 4 pairs of V-columns installed out of 7 at the platform level, the horizontal roof frames were installed, allowing the support structures to be removed from one pair of V-columns. Construction of the plant room at the southern end of the station also had begun.

15 September 2024

8 September 2024

JS5 - Corporation (Contract J103)
In a nutshell: With Jurong West Avenue 2 diverted around the station, work began on the construction of the remaining viaduct piers leading to the junction with Corporation Road & Bulim Avenue. The next several layers of station roofing were being installed over the nearly completed roof frame. Viaduct construction continued along Jurong West Avenue 2.

15 September 2024

JS6 - Jurong West (Contract J105)
In a nutshell: With the roof frame completely installed, construction had progressed onto the platform level plant rooms at the station. Work was also progressing well for the viaduct spans west of the station building with parapet wall installation taking place, followed by the cable brackets and troughs. Segment launching was in progress for viaduct piers on the eastern side of the station building.

15 September 2024

JS7 - Bahar Junction (Contract J105)
In a nutshell: Roof frame installation had begun at the station recently with one pair of Y-columns installed at the main station building. A second pair sat at street level with additional components being welded to the structure before lifting up into position. The two lift frames were installed at the main station building as well. Protective structures were installed underneath the satellite station building, allowing work to proceed above the diverted roadways below the station. Segmental box launching was also taking place for the various viaduct spans around the junction.

15 September 2024

JS8 - Boon Lay (Contract J106)
In a nutshell: A slightly taller station requires slightly more time to achieve the same amount of progress as her slightly shorter stations that require slightly shorter amounts of time for similar degrees of completion. Being four stories tall, works are racing at Boon Lay to bridge the two sections of the station over the existing East-West Line (EWL) tracks. Not quite there, but probably soon. Over at the existing EWL station, modification works were underway although not quite in full swing as yet. Works to push the exit staircase further out seem to have come along while construction for a new replacement ramp had also begun.

15 September 2024

JW1 - Gek Poh (Contract J107)
In a nutshell: Most of the beam installation works at the station had completed and casting of the final in-situ beams was underway. These beams sit on the outer-most end of the station's concourse slab. At the northern end of the station, installation of the first precast beams had begun for the trackbed within the station building. Viaduct span construction works progressed south of the station.

15 September 2024

JW2 - Tawas (Contract J107)
In a nutshell: Plant rooms at the southern end of the platform have commenced construction. Portions of the metal frame for the roof were also present on site. Construction on the southern side of the special span crossing over the expressway has been completed while pending the completion of the pier on the northern side.

15 September 2024

Phase 2
Although this section has more time to complete works than stations under phase 1, there are always cases of over-achievers trying to show off. At least one of the stations along this section has begun installation of the metal frame that will eventually support the roof over the station's platform. Elsewhere, station buildings are in various stages of construction stretching from the street level up to the platform levels.

JE1 - Tengah Plantation (Contract J108)
In a nutshell: Viaduct span construction has progressed very close to the station building. It appears that progress has been slightly stunted pending the crossing of the launch gantry through the station with the trackbeds fully cast at platform level. Several spans of viaduct will need to be completed once the gantry traverses through the station.

8 September 2024

JE2 - Tengah Park (Contract J108)
In a nutshell: Our show off station - by mid-month, approximately 4 frames that will eventually support the station's roof had been installed at concourse level. The design at this station calls for a frame system that starts at the concourse and is anchored to the station's support piers. Viaduct construction on either side of the station was left with approximately 1 span per bound to join up with the station building, allowing a continuous stretch of viaduct through which the contractor could move to parapet wall installation and subsequent works.

8 September 2024

JE3 - Bukit Batok West (Contract J108)
In a nutshell: The station was the slowest in progress along this contract in particular. Nonetheless, progress was made with all the station's piers finally moving beyond foundation level. Part of the station's concourse level had already been cast as well with the station pier columns at concourse level following suit. To the west of the station, launch gantry Rock Steady was disassembled and transported across Bukit Batok Road for reassembly next to the station building.

15 September 2024

JE4 - Toh Guan (Contract J109)
In a nutshell: Approximately half of the station's concourse level crossheads had been cast. The completion of crosshead casting would allow works to move onto the next stage of construction where beams are to be installed and allow traffic below to flow uninterrupted. Viaduct pier construction south of the station was continuing while piers north of the station had been completed to crown level.

15 September 2024

Tracks through Jurong East Integrated Transport Hub (Contract J120)
In a nutshell: More sections of the viaduct spans had formwork assembled ahead of casting as the viaduct moved closer towards the Jurong Hub building structure. Due to the stacked nature of the line at Jurong East station, interesting looking piers could be seen near the interchange station.

15 September 2024

8 September 2024

JE5 - Jurong East (Contract J110)
In a nutshell: With the concourse level mostly cast, work had since moved onto the lower platform level. Rebar installation was proceeding at a very quick pace with several key portions of the station - such as trackbeds - becoming clearer as installation work progressed. Protective netting has begun going up along the westbound EWL track as the station grows taller.

15 September 2024

JE6 - Jurong Town Hall (Contract J109)
In a nutshell: The station's concourse level was completely cast and the western section had progressed to work on the platform level. Recently, the contract's launch gantry was assembled and is to begin viaduct span construction works shortly.

15 September 2024

JE7 - Pandan Reservoir (Contract J107)
In a nutshell: Most of the station had begun construction of the mezzanine level. Similar to Boon Lay station, a slightly taller station requires slightly more time to achieve similar rates of construction progress as its neighbours. Several of the viaduct piers also began having the pier crowns cast.

15 September 2024

Phase 3 (South)
The last phase of the line is not to be outdone either, with noticeable progress at the southern section. Several new viaduct piers could be seen along with other station piers. Segment launching was well underway for certain sections too.

JS9 - Enterprise (Contract J111)
In a nutshell: Concourse level construction had begun from the centre of the station as most of the station pier columns were completed. To the north of the station, several viaduct segments had been lifted into place by the hanger beams and were ready to transition to the use of lifting frames.

15 September 2024

JS10 - Tukang (Contract J111)
In a nutshell: Most of the station's piers had now been cast. The next stage of construction would see the works focusing on getting the concourse level crossheads completed. In addition to the station piers, one viaduct pier near the contract boundary with J112 was seen completed to crown level as well.

15 September 2024

JS11 - Jurong Hill (Contract J112)
In a nutshell: South of the expressway, two station piers have come up along Jurong Pier Road. On the northern side of the expressway, two viaduct piers have been completed to crown level with the southern-most one heading into crosshead construction.

15 September 2024

JS12 - Jurong Pier (Contract J112)
In a nutshell: Three cylindrical columns in the station's centre still remain as three columns, with others not joining them in the time since the last update in August. Works appear to have been focused on other sections of the station. Further north, some site clearing work has taken place for the viaduct piers to be constructed.

15 September 2024

Phase 3 (North)
The northern section of the phase has also made significant progress with most of the station structures now visible. Sections of the viaduct spans were also completed, although there were still sections where viaduct piers were missing.

JW3 - Nanyang Gateway (Contract J113)
In a nutshell: Most of the station's portal pier columns were completed, with the concourse level beams also installed in the station's centre portion. On either end, viaduct span construction had made decent headway with several stretches of viaduct spans completed. A few piers here and there remain to be constructed owing to road diversions creating sufficient space for the construction of the pier foundations and columns.

15 September 2024

JW4 - Nanyang Crescent (Contract J113)
In a nutshell: One of the few stations to have platforms at-grade, works at the station clearly show the location of the station's trackbeds. The telltale stubs can be clearly seen with low walls on either side for the under-platform equipment and ducting in place.

15 September 2024

JW5 - Peng Kang Hill (Contract J115A)
In a nutshell: Portions of the station's foundations and columns can be seen making an appearance as the station progresses upwards. To the north of the station, a section of the line will be built on an embankment or retaining-type structure, for which the foundation piles can be seen cast. Viaduct piers were taking shape with construction moving onto the crosshead level.
