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:

• Contract J101 for Tengah Depot
• Contract J102 for Choa Chu Kang, Choa Chu Kang West & Tengah stations
• Contract J103 for Hong Kah & Corporation stations
• Contract J105 for Jurong West & Bahar Junction stations
• Contract J106 for Boon Lay station
• Contract J107 for Gek Poh & Tawas stations

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.

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.

Contract J108 is the first of two contracts that cover three stations each - the other being neighbouring contract J109 which we'll be covering in the following post. Over the first three months of the year, work has been chugging along with viaduct spans taking shape and the station buildings slowly being cast. We take a closer look at the three stations under this contract - Tengah Plantation, Tengah Park & Bukit Batok West - in greater detail after the jump.

J108 - Tengah Plantation, Tengah Park & Bukit Batok West update Q3 2023

Stations under contract J108 as on 24 September 2023.

A lot has happened last quarter over at contract J108 which is for the construction of 3 phase two stations at Tengah Plantation, Tengah Park & Bukit Batok West. Also part of the package are viaducts from Tengah Junction, where the line diverges from the western route, up to the interface with contract J109 along the Pan Island Expressway (PIE), south of Bukit Batok town. In order to speed up the updates ahead of the year-end recap that we're in the midst of preparing, we're updating the rest of the line by contract. Head on past the jump for loads of pictures about the progress made over Q3 2023.

J108 - Tengah Park update Q2 2023

The past quarter (Q2 2023) has been a busy period for contractor McConnell Dowell over at contract J108 for the construction of stations and viaducts at Tengah Plantation, Tengah Park & Bukit Batok West. The portion of viaduct spans north of Tengah Park station up to the point where the line veers off Bukit Batok Road and into Tengah has been completed. Work on the station structure at Tengah Park has taken off with the columns visible at the street level before the concourse level is added in. A second launch gantry is also being assembled to commence viaduct span construction on the southern side of the station.

Yesterday, the second launch gantry for contract J108 was raised into position south of Tengah Park station. The gantry will begin work assembling the viaduct spans for the cripple siding located here. The lifting process utilised 2 mobile crane units that lifted the gantry in a process known as a tandem lift. Once elevated to the desired height, the cranes swung the gantry over to the final position atop the supports and the gantry was locked in place.

With thanks to Alfred Yeo Chi Jin, a resident of Bukit Batok West for contributing these photos with regularity, we have been able to observe the process of transferring a launch gantry from one trackway to another. The transfer was completed over a course of several days by sliding the supports across a beam that helped to keep the gantry in place.

J108 - Tengah Park's third span

College, along Bukit Batok Road before the line swings into Tengah.

Its a new week and we kick it off with an update on the Jurong Region Line (JRL) at contract J108. This was the first contract to begin viaduct construction despite being under phase 2 of the line, which is only due to open in 2028. Thanks to Alfred Yeo, who has kindly contributed his pictures, we have some early photos from last week when the construction of the third span was in its infancy.

The Six Stages to building an elevated MRT line - Preparatory Works (1)

 

We launched our new mini-series last week, a deep dive into the process of building an elevated MRT line which was last seen on the East-West Line when the Tuas West Extension was built. Join us as we explore the first of six distinct stages of bringing an elevated MRT line to life - the preparatory works stage.

Reader Alfred Yeo Chi Jin, a resident of Bukit Batok West, kindly sent us a series of images of the contract J108 launch gantry. Good progress has been made with a second span nearly completed. The second span starts where the first currently ends, with the segmental box girder that has been bonded with the viaduct pier. The other end of the span will be located at a movement joint pier which uses bearings to support the viaduct instead of being bonded to the segmental box.

Time waits for no one is an often heard phrase. This seems to hold true when one speaks about the pace of works at contract J108 in getting the first viaduct span for the entire Jurong Region Line (JRL) completed. What makes this an amazing feat is the fact that this contract is actually part of the second phase, yet it is the first to have a viaduct span nearly entirely launched. What works in the contract's favour is that it is mostly located within untouched greenfield sites which require minimal utility diversion works before works can progress.

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.

Contract J108 is for the construction of 3 stations on the Jurong Region Line (JRL), however we will only be covering the 2 stations within Tengah for this contract in this post. No worries, the next station will be covered in the following post so no losing out there. While contract J108 may fall under the second phase of the line, works at this contract are progressing at lightning speed.

J108 - Another major milestone

BUKIT BATOK ROAD - Its up! Its hanging, suspended in the air. As you drive along, you might be able to spot a blue truss-like structure on the side table of the road. Might may not be quite the right word as the structure is pretty hard to miss. But if you're driving, best not to be distracted... Hence the use of the word, might.

J108 - Tengah Park progress

 

02 October 2022 - An aerial view of the contract J108 construction site
near Tengah Park station.

The construction site under contract J108 near Tengah Park station has come a long way in the past 9 months. The first viaduct piers for the Jurong Region Line (JRL) were spotted along Bukit Batok Road here. These piers now support the first seen segmental box girders which are being bonded ahead of viaduct construction. October seems to be the target month for several contracts to begin construction of viaducts with several circulars for other contracts also seeming to indicate this as the start date for this phase of construction.

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

We'd like to wish all our readers a Happy & Prosperous Lunar New Year! May each of you be blessed with bountiful fortune in the year of the Tiger. And to all the contractors on the Jurong Region Line (JRL) project, may you all experience good health (and safety) this coming year.

Through the Chinese New Year period, we have been travelling around a fair bit and noticed the first viaduct piers for the line beginning to emerge above the hoarding protecting the worksite.

J108 Construction Update - Q3 2021

25 September 2021 - A view of the route as the line swings in to Tengah estate as seen from Bukit Batok Road.

Phase 2 of the Jurong Region Line (JRL) is the final phase we cover in our update for Quarter 3 of 2021. This phase consists of 4 contracts - J108, J109, J110 and J120 for the construction of various parts of viaducts and stations. Contract J108 was won by John Holland-McConnell Dowell and will connect phase 2 to the rest of the line at phase 1's Tengah interchange station. The contract will involve the construction of 3 stations at Tengah Plantation, Tengah Park & Bukit Batok West.

As this post is rather photo-heavy, we have decided to break the post up according to contract for easier readability. Do look out for our subsequent posts on other sections of the line.
