We're moving onto recapping the Q1 2025 progress of contract J102, awarded to Shanghai Tunnel Engineering Co. This contract of the Jurong Region Line (JRL) saw several key milestones being hit this past quarter, including but not limited to completion of viaduct segment launching, the commencement of roof frame installation works at the stations and the installation of escalators within the stations. We'll cover these in greater detail as we look at each station site closer.

J150 - Trackwork update Q1 2025

8 March 2025 - A sleeper-laying machine on the Jurong Pier-bound track near Hong Kah station.

Track laying and related installation works - referred to as Track Related Installation Programme (TRIP) - commenced on the Jurong Region Line (JRL)'s main line following the handover of sections of viaduct near the Tengah Junction by contract J102 in August 2024 to the trackworks contractor under contract J150. This represented the first contract where viaducts were handed over for TRIP purposes. TRIP works will encompass the laying of rails (both running rails and the third rail as well), cabling for communications, signaling infrastructure and platform screen gates among other components. For this post, we'll look specifically at the rail laying component as this is among the first activities to be initiated under TRIP works as locomotives and wagons will use the installed rails for subsequent installation activities.

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.

J102 - STEC update for Aug/Sep 2024

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.

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.

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

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.

With Q1 of 2024 coming to a close soon, we're beginning our quarterly updates on the Jurong Region Line (JRL). Last week, we covered the progress of Tengah depot over the first quarter, including the commencement of trackworks! Today, we'll dive a little deeper into the works taking place under contract J102 by Shanghai Tunnel Engineering Co which includes 3 stations, approximately 4km of viaducts and a future shell station.

It has been a while since we've posted about the work going on within Tengah, so it'd be a good opportunity to cover this area which has seen a significant amount of progress. Since the start of the year, two launch gantries have been set up within Tengah new town to begin constructing the network of viaducts that will allow the Jurong Region Line (JRL) to run onwards to both Jurong Pier and Pandan Reservoir. We explore more of the progress of the Tengah junction point and briefly on Tengah station in this post - do note that this is a picture-heavy post.

J102 - Flythrough videos

Recently we came across several render videos for contract J102. The first video shows the renders of Choa Chu Kang, Choa Chu Kang West & Tengah stations which are being built by contractor Shanghai Tunnel Engineering Co (STEC). Subsequent videos show the process of unloading components of the launch gantry at the storage site, assembly & lifting of the launch gantry used for viaduct construction and the construction of the base slab at Choa Chu Kang station.

JRL Groundbreaking and Viaduct Launching Ceremony on 13 Jan 2023

The Sg MRT Construction team is grateful to have been invited to the groundbreaking and viaduct launching ceremony of Jurong Region Line (JRL).

The event took place last Friday (13 Jan) morning, near the future JS3 Tengah station within contractor Shanghai Tunnel Engineering & Construction Co's J102 worksite and in proximity to where the east and west route tracks split.

Minister S Iswaran's arrival was marked by a lion dance performance, in time for the Chinese New Year festivities and for good luck and blessings on this special occasion.

The ceremony was graced by multiple grassroots advisors from the Jurong and West Coast region GRCs and SMCs, whose residents will be served by (and in the interim, affected by the works for) the JRL.

We're happy to share that we've collaborated with @booms_and_ladders (Cranes & Fire Trucks) on Instagram to bring you some professional pictures of the construction within contracts J102 & J108. This post will mostly be a photo collection for your viewing pleasure and we look forward to more such collaborations down the road to offer high quality images that capture the works that may serve as a repository as the landscape changes over time.

J102 - Peeking at the progress within Tengah

 

27 November 2022 - A viaduct pier with the crosshead already cast is visible beyond the BTO flats
currently under construction along the eastern stretch of Tengah new town.

It was a drab, rainy morning. The build-to-order (BTO) flats have risen quicker than the progress on the Jurong Region Line (JRL) within Tengah is visible. But from a high vantage point, just barely visible to the eye, was a view of some of the work for the line within Tengah. Mostly out of reach at the moment, work has been going on steadily to get viaduct piers at the southern end of contract J102 ready. As they progress further north, they get much trickier as the line's branches merge at the centerpiece station of the line - Tengah.

Recently we came across some new renders of the stations along the Jurong Region Line (JRL). We thought it would be fitting to do a re-post of all the renders we've amassed thus far. Do stay tuned as we'll let you know where we got the new renders from after the phase 3 batch.

J102, J108 - Progress update

 

25 April 2022 - The beginnings of viaduct piers north of Choa Chu Kang station.

Its been a while since we caught up to how things are shaping up on the Jurong Region Line (JRL). Things are indeed picking up pace! We've made a few comparisons to how things looked in the past as far as possible. For this post in particular, we'll be covering the stations under contract J102 (Choa Chu Kang, Choa Chu Kang West & Tengah) and also Tengah Park under contract J108.

Launch gantries on site

Contract tendering update - J102, J103, J110 & J106

The contract tendering process for the Jurong Region Line (JRL) civil contracts began last October with the release of tender for contract J101 for the construction of the depot to be located in Tengah. Since then numerous other tenders have been floated, of which the tenders for 3 contracts have been closed - contracts J102, J103 and J110.

Contract J102 is for the construction of Choa Chu Kang, Choa Chu Kang West and Tengah stations on the JRL. It also includes addition & alteration (A&A) works to the existing Choa Chu Kang station on the North South Line. Tender for this contract closed on 22 February and a total of 10 contractors have made bids.

Pre-Construction - Tengah, Hong Kah & Tengah Plantation

Being built as a new township, Tengah estate will see several Jurong Region Line stations serving the different districts within the town. Tengah station is to be located at the town centre, Hong Kah station will serve the southern portion while Tengah Plantation station serves the plantation residential district. In future, another station may be added further north between Tengah and Choa Chu Kang West stations to serve the north eastern portion of the town. All of these stations lie within a currently heavily vegetated area and works are underway to clear the area for construction activities to commence on the new town.

Contract tendering update - J101, J102, J103, J105, J110

Following the official announcement of the Jurong Region Line (JRL) in May 2018, the tendering process for the civil contracts began around November last year. To date several large civil works contracts have been floated for tender.

Contract list as of 18 February 2019.

These include the civil works contracts for the construction of Tengah depot (contract J101), Choa Chu Kang interchange, Choa Chu Kang West and Tengah stations (contract J102), Hong Kah and Corporation stations (contract J103), Jurong West and Bahar Junction stations (contract J105) and Jurong East interchange (contract J110). In total, there should be approximately 13 civil works contracts for the line. To date 5 of these contracts have been floated and 1 contact - J102 - has been closed.

Contract awards can be expected approximately 6 months after the closure of the tender while tender of the remaining contracts should be expected to be completed by the year-end. Once the contracts have been awarded, a ground breaking ceremony will be held - potentially some time after the first quarter of 2020. This is when construction along the line will begin to ramp up in intensity. In the meantime, advanced work contracts are underway to facilitate the relocation of utilities, with the bulk of these contracts due for completion by September 2020.
