Saturday, December 21, 2024

J113 & J115A / Nanyang Technological University stations - A 2024 progress report

As the Jurong Region Line (JRL) comes to the end of its run in Peng Kang Hill, so do we in our JRL 2024 progress report. This report marks the completion of our coverage for the line's progress updates over 2024. Before we jump into that, you can recap the rest of the line's progress in the various reports we've produced this month:

In our final update report, we cover the remaining two contracts for the phase 3's northern section in Nanyang Technological University (NTU). Served by three stations, the first two are being constructed under contract J113 and the final station under revised contract J115A. All three stations and two contracts were awarded to the same contractor - Hwa Seng Builder - easing the process of construction and standardisation of noise mitigation & environmental control measures. Some milestones that the contracts in this section have accomplished include the commencement of station building construction and commencement of viaduct segment launching works. More details can be found after the jump!

J111 & J112 / Jurong Industrial Estate stations - A 2024 progress report

We're on our way to wrapping up the progress made over the Jurong Region Line (JRL) through 2024. Thus far, we have covered the contracts for the stations, depot and viaducts under phases 1 & 2:

We now begin our final posts to conclude the progress report series with 2 more posts covering phase 3's southern and northern sections. This particular report will cover the southern section through the Jurong Industrial Estates.

Phase 3's southern section spans across 2 contracts - J111 & J112, each responsible for two stations. Milestones for the first contract - J111 - include the commencement of viaduct segment launching & construction and the commencement of station concourse level construction. Meanwhile, milestones seen over at the second contract - J112 - have included the commencement of station pier construction at Jurong Hill station and the commencement of viaduct segment launching works. We'll dive a little deeper into the specifics right after the jump.

The final two contracts under Phase 2 of the Jurong Region Line (JRL) are located at Jurong East. Before we dive into the 2 contracts' combined report, here are the reports for other contracts that we've covered thus far:

Milestones for contract J110 for the construction of the Jurong East interchange station have included the commencement of structural works for the upper platform level of the station, commencement of construction of ground level columns for the transfer hub & plaza and the completion of the two viaduct piers to the station's north. On the other hand, milestones for contract J120 have included the progressive expansion of casting works for the in-situ viaduct spans, commencement of casting works for the Integrated Transport Hub (ITH) building structure over the JRL viaducts and the commencement of ITH tower building structure works. More details to follow, after the jump!

J109 / Toh Guan, Jurong Town Hall & Pandan Reservoir - A 2024 progress report

We're into phase 2 of the Jurong Region Line (JRL) 2024 progress report. Before we jump into all the details for contract J109, here are some of the previous contracts that we've reported on for the year:

Moving onto contract J109 proper, some of the milestones that the contract has seen this year includes the completion of casting of concourse level crossheads at Toh Guan station and the commencement of viaduct segment launching at Jurong Town Hall. This contract is a little less advanced in terms of progress as compared to contract J108, but nonetheless has been making steady progress as well. All the details after the jump.

J108 / Tengah Plantation, Tengah Park & Bukit Batok West - A 2024 progress report

We've been on a journey re-looking back at the progress made through the year at the various Jurong Region Line (JRL) contracts. Thus far, we've gone through the phase 1 contracts, which you can view here:

Having completed the rotation of phase 1 contracts, we now venture into phase 2 territory. These stations will open a year later than their phase 1 counterparts and will serve a separate service on their own, unofficially called the eastern route, which consists of 7 stations. The first contract along this phase is Contract J108, which was awarded to a joint venture between McConnell Dowell & John Holland.

Milestones attained by this contract thus far have included the completion of casting all precast segmental boxes for viaducts, the commencement of roof frame installation works at two (2) stations and the commencement of linkbridges connecting to station exits at one (1) station. Of the phase 2 contracts, this one is slightly ahead of the others. More details after the jump.

J107 / Gek Poh & Tawas - A 2024 progress report

Making headway through our 2024 progress report, we've come to the sixth contract and the final one under the first phase - contract J107. In case you missed them, here are the first five parts of the 2024 progress report thus far:

Contract J107 for the Jurong Region Line (JRL) was won by Chip Eng Seng - Sembawang Design Corporation (CES_SDC) and involves the construction of two stations at Gek Poh and Tawas. Both of the stations will utilise side platform layouts. Significant milestones attained through 2024 have included the completion of casting for all viaduct piers along the contract, the commencement of roof frame installation works at Tawas station and the long span crossing over the Pan Island Expressway reaching the mid-point. We take a closer look at the various accomplishments made in greater detail after the jump.

J106 / Boon Lay - A 2024 progress report

To wrap the year, we've started a series called the 2024 progress report. This series aims to recap all the accomplishments and changes made through the work at the various sites over the year. Here are the other parts for the Jurong Region Line (JRL) thus far:

This contract has seen a lot of progress through 2024. Some of the highlights would include the completion of viaduct segment launching, the commencement of viaduct span preparation for handover to track laying contractor and the commencement of exit construction. Contractor China Communications Construction Co (CCCC) has been working steadily and safely in spite of all the challenges faced along the contract's length. We recap all of these after the jump.

J105 / Jurong West & Bahar Junction - A 2024 progress report

Contract J105 stations as at the end of 2024.
Top: Jurong West station
Bottom: Bahar Junction main station building

The Jurong Region Line (JRL) 2024 progress report continues with an update on contract J105, responsible for the construction of Jurong West & Bahar Junction stations. This is the fourth update in the series to close off an update on the progress made along the JRL over the 12 months of the year. Here are the first three posts in the series:

Several milestones were achieved through the year under the contract. These include the completion of significant stretches of viaduct spans along Jurong West Avenue 2, completion of the two concourse level spans for the Bahar Junction satellite station building and the commencement of roofing works at both stations. Parapet wall works had also begun between the two stations. As of end 2024, work was going on to complete the remaining sections of viaducts where gaps were still present. We'll take a look at all of China Railway No 11 Bureau's accomplishments for 2024 after the jump.

J103 / Hong Kah, Corporation & Reception Tracks - A 2024 progress report

Stations of contract J103 seen at the end of 2024.

We're on a roll to wrap up progress made on the Jurong Region Line (JRL) through the 12 months of the year. This series began with contract J101 for the Tengah depot and was followed by contract J102 for Choa Chu Kang, Choa Chu Kang West & Tengah stations. We'll now continued on to contract J103 for Hong Kah and Corporation stations & the connecting Reception Tracks that link the main line with the depot.

Contract J103 has done well on the station building front but suffers on the viaduct construction aspect. The station buildings at both Hong Kah & Corporation have advanced to the stage of installation of the station roof frame and subsequent roofing works. However, there remain large gaps in the viaducts where spans were not yet constructed or viaduct piers were still being built. Of importance though, is to note that the former joint venture between Eng Lee & Wai Fong was affected by the former's financial performance which ultimately saw the company shut down, leaving the latter to carry on with the project as the sole contractor. More on these issues after the jump.

J102 / Choa Chu Kang, CCK West, Forest Hill & Tengah - A 2024 progress report

The stations of contract J102 in December 2024.

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.

Into the fourth quarter of 2024 we go. Work at the various sites of the Jurong Region Line (JRL) continues to chug along with different sites focusing on different stages of work. We bring a brief update of the progress made since the last update in September 2024.

A short summary of the various station construction statuses as of October 2024.

J102 - STEC update for Aug/Sep 2024

Video by STEC, uploaded to SGMC YouTube

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.

J110 & J120 - Jurong East update Q2 & Q3 2024

Contracts J110 (top) and J120 (bottom) as of end-Q3.

To speed things up and keep our updates a little more current, we'll be combining the updates for both Q2 and Q3 for the remaining contracts (J110, J111, J112, J113, J115A & J120) of the Jurong Region Line (JRL). Hopefully, this gives our reads a more timely perspective of the works progression.

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.

J102 - New layout at Choa Chu Kang

8 September 2024 - A view of the station's Exit A with the partially relocated fareline in view.

7 September 2024 - Another view of the relocated fareline.

We earlier detailed the changes being made to Choa Chu Kang station. Over the past week or so, some of these changes to the existing station's concourse area have been changed. The existing fareline nearer to Exit C has been shifted further out towards Exit A. In addition, the new passenger service centre (PSC) for the North-South Line (NSL) has been put into service, with the old PSC being closed for service.

J109 - Toh Guan, Jurong Town Hall & Pandan Reservoir update Q2 2024

Contract J109's three stations as of end-Q2.

Contract J109's three stations - Toh Guan, Jurong Town Hall & Pandan Reservoir - saw slight progress. The station site with the most progress over the quarter was Toh Guan, which saw the station's concourse level crossheads constructed. Works at Jurong Town Hall and Pandan Reservoir station were unfortunately a little slower through the quarter, with not as much visible progress seen. We take a look at the progress made through the quarter after the jump.

J108 - Tengah Plantation, Tengah Park & Bukit Batok West update Q2 2024

An overview of contract J108 stations at Tengah Plantation (top), Tengah Park (middle) and
Bukit Batok West (bottom) as of end-Q2 in June 2024.

Over Q2, contract J108 has seen the stations at Tengah Plantation & Tengah Park continue to take shape. Work at Bukit Batok West has also began to speed up with the structure of the station becoming more visible as more station columns are cast. Viaduct construction work also pushed further into Tengah. while causing some road diversions, ultimately inching towards completion. Other developments were also made in completing the various spans using the launch gantries Rock Steady and Magnificent Mammoth. More information after the jump.

August has been a busy month for the Jurong Region Line (JRL) with several milestones being achieved. Contract J102 saw the handover of completed viaduct spans to trackworks contractor under contract J150 and contract J109 saw the lifting of the launch gantry for viaduct construction at Jurong Town Hall's station site. In addition, roof frame installation works were ongoing at Hong Kah (JS4), Corporation (JS5) and Jurong West (JS6) stations. More details on the progress made at the various sites after the jump.

J102 & J150 - Handover of completed viaducts at Tengah for track works

A milestone moment has been reached in the construction of the Jurong Region Line (JRL). A section of the under construction viaducts in Tengah have been successfully handed over to trackworks contractor China Railway First Group this week. This section of viaducts, under contract J102 by Shanghai Tunnel Engineering Co, has seen the installation of cable racks, cable troughs and first stage concreting before the handover was effected.

J107 - Gek Poh & Tawas update Q2 2024

A view of contract J107 stations at Gek Poh and Tawas in end-Q2.

Advances in the progress of Gek Poh and Tawas stations were seen over Q2 of the year. At Gek Poh station, the concourse was largely completed while over at Tawas, the platform level beams were coming along well. Viaduct progress along contract J107 was also making headway, with viaduct spans stretching longer and longer through the quarter. Join us as we dive into the progress update for the contract over the second quarter of 2024.

J106 - Boon Lay update Q2 2024

16 June 2024 - An aerial view of the new JRL station building and viaducts of contract J106.

Contract J106 for the construction of Boon Lay station and viaducts for the Jurong Region Line (JRL) has seen steady progress at its site through Q2 of the year. Through the quarter, the station building has continued to take shape with the structure rising from the concourse level on the third floor to the platform level on the fourth floor. Eventually, both halves of the station to the north and south of the existing East-West Line (EWL) viaduct will meet above the operational line.

J105 - Jurong West & Bahar Junction update Q2 2024

A view of the Jurong West (top) and Bahar Junction (bottom) stations under contract J105 as
of end-Q2.

Along phase 1, contract J105 is without a doubt one of the most interesting contracts to observe, given that it encompasses the construction of the unique Bahar Junction station. Also included under the contract is the more tame and templated Jurong West station. Over the past quarter, gains have been made in both stations' construction. The viaducts along the stretch were also coming together as well, with sections of completed spans progressing to the next stage of construction.

J103 - Hong Kah & Corporation update Q2 2024

Hong Kah & Corporation stations as seen in end-Q2.

Contract J103 has seen some of the greatest progress in station construction while at the same time, the slowest of viaduct progress among the first phase of the Jurong Region Line (JRL). Over the past quarter, Corporation station has emerged as the most complete along the line while Hong Kah's stagnated progress has finally made some headway. The viaducts however, were still far from completion - a critical component of the line and its operation, given that the viaducts under the purview of the contract also connect the main line with the depot. We'll explore the progress made under the contract over Q2 in greater detail after the jump - do be fair warned, this post is highly picture-intensive.

J102 (Part 2) - Forest Hill & Tengah update Q2 2024

The future infill station and the approach tracks to Tengah station under contract J102 as seen
in end-Q2.

Last week we covered the first update for contract J102 over the second quarter of the year. This week, we're continuing our update with the remaining 2 stations under the contract - the future infill station just inside Tengah that we're calling Forest Hill and Tengah station, located at what will become the future town centre. As we learnt last week, a lot has happened within contract J102 over the past quarter. Works have been progressing at a frenzied pace, with viaducts within Tengah taking shape - more so than those within Choa Chu Kang. The station buildings are also substantially completed to the platform levels, although Forest Hill's structure is a very basic frame. In this update, we take a closer look at the goings-on around the two station locations.

J102 (Part 1) - Choa Chu Kang & Choa Chu Kang West update Q2 2024

24 June 2024 - A view of Choa Chu Kang & Choa Chu Kang West stations under contract J102
as of end-Q2.

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.

The various contracts along this phase are rushing to have the civil works completed in order to meet the targeted completion date. We understand that the targeted completion of works for Phase 1 would be around end-2026. In order to allow for sufficient time for fitting out and testing of systems, the basic structures would need to be completed approximately 2 to 2.5 years ahead. Given that this will be the first section of line to begin operations, further time may be required for testing of the new equipment to ensure that all issues are ironed out sufficiently.

Meanwhile, Phase 2 has a targeted completion date of mid-2027. Bringing up the remainder of the line, the targeted completion date for Phase 3 of the line is by September 2028. As such, the contractors for Phase 1 should begin feeling the pressure to meet the deadlines for handover of the completed structures to the trackworks contractors for the next phase of construction.

J101 - Tengah depot update Q2 2024

2 June 2024 - An aerial view of the Tengah depot in end-Q2.

Bit by bit, the Tengah depot - home of the Jurong Region Line (JRL)'s trains and operations, is inching towards a semblance of completion. The depot is one of the keys to enabling the line to function and be commissioned. Without the depot, it becomes a tremendous task to ensure that all the line's systems are able to integrate and function collectively as the line is commissioned ahead of opening. In the months prior to the line's opening, testing of the rolling stock (trains) will need to be done within the depot. This process requires the stabling shed, workshops, test tracks and operations control centre to be ready.

At present, none of these buildings are in a state ready to receive any units of the rolling stock. There are no paved roads within the compound to facilitate the delivery of the rolling stock either. Based on how the site looks, the stabling yards may be the first buildings to be ready for the delivery of the rolling stock. In this post, we'll take a deeper look at the progress made at the depot over the past quarter and size up what needs to be done to get it in basic shape for rolling stock delivery to happen.
