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:

• 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
• Contract J108 for Tengah Plantation, Tengah Park & Bukit Batok West stations

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.

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.

Contract J106 entails the construction of Toh Guan, Jurong Town Hall and Pandan Reservoir stations. Over the past quarter, the most changes can be seen over at Toh Guan station with the formwork for the first station pier's concourse level crosshead can be seen. At Jurong Town Hall however, things were a little slower with casting work continuing over at the concourse level slab. Pandan Reservoir station saw similar progress, with work still mostly focused on the street level foundations and underfloor cable troughs. We'll dive deeper into the works at the various sites under the contract.

A compilation of progress at the 3 station sites as at September 2023.

Q3 of 2023 has been a fruitful one for contract J109. Although there may not have been as visible progress as contract J108, the stations and viaduct piers under this contract has been making in-roads to completion of the structures for the line. Do check out the progress report for contract J109 after the jump!

J109 - Toh Guan update Q2 2023

 

16 April 2023 - A view of the viaduct piers along Bukit Batok South.

Toh Guan station falls under contract J109, one of the most unusual and interesting contracts we have seen in a while. This is largely due to the fact that the contract is split into two sections - the northern section where Toh Guan station is located and a southern section which continues after connecting near Jurong East station. For this update, we're looking at the northern section of the contract which begins with 5 viaduct piers along Bukit Batok South, parallel to the Pan Island Expressway (PIE). Works here have been progressing steadily and without much fanfare. This is our Q2 2023 update for Toh Guan station.

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.

J109 - Toh Guan year-end update

 

18 December 2022 - A view southwards to Jurong East station. The contract J109 work site will
extend all the way to the Jurong East junction where the contract splits to allow work under
contracts J120 and J110. It then resumes along Jurong Town Hall Road.

Toh Guan is the first of 3 stations to be built under contract J109. This contract in particular is a little peculiar, being split in the middle with contracts J120 and J110 for the construction of the Jurong East integrated transport hub & Jurong East interchange station respectively. Not entirely sure why the contract was packaged this way, but we're here for updates anyway. A recent road diversion in November has now paved the way for work on station foundations to commence once the former roadway can be cleared.

We hope that you've enjoyed our previous post on the renders of the phase 1 stations of the Jurong Region Line (JRL). We're back with more now, this time for phase 2 which will run towards mega-hub Jurong East and onwards to the Pandan Reservoir.

As our previous post was getting rather long, we decided to split up the updates for easier readability. This section will cover updates on contract J109, the second contract under phase 2 of the Jurong Region Line (JRL). Contract J109 was won by Daewoo - Yongnam joint venture and involves the construction of Toh Guan, Jurong Town Hall & Pandan Reservoir stations. Interestingly this contract is split into 2 sectors located north and south of Jurong East interchange which will be built under a separate contract, being contract J110 won by Daelim.

J109 - Soil investigation & Utility tracing

 

18 April 2019

Contract J109 entails the construction of Toh Guan, Jurong Town Hall and Pandan Reservoir stations for the Jurong Region Line (JRL). A strange contract as it is broken into two sections - the northern section which involves Toh Guan station and the southern section which involves the other 2 stations. In between are contracts J120 and J110 for the construction of viaducts through the Jurong Hub integrated development & construction of Jurong East interchange station respectively.

Contract awards - J109, J152, J155 & J160

On Friday, the Land Transport Authority (LTA) announced the award of 4 contracts for the Jurong Region Line (JRL). The first contract awarded was for J109 which will include the construction of Toh Guan, Jurong Town Hall and Pandan Reservoir stations along with associated viaducts and commuter facilities. This contract has been awarded to the joint venture of Daewoo Engineering & Construction Co Ltd - Yongnam Engineering & Construction Pte Ltd. Daewoo is currently constructing the Stevens station on the Thomson-East Coast Line while Yongnam has been a key supplier of struts used in the construction of several underground MRT stations.

JRL2 - All contracts released for bid

The Land Transport Authority released the last tender for phase 2 of the Jurong Region Line (JRL) on 31st July 2019 - contract J109 for the design & construction of Toh Guan, Jurong Town Hall and Pandan Reservoir stations, viaducts inclusive. With the release of tender bidding for contract J109, all contracts for phase 2 of the line have been floated for tender.

Pre-construction - Toh Guan

Toh Guan and Yuhua estates are located next to Jurong East Central and have long been seeing MRT trains passing by since the line to Choa Chu Kang began operating in 1990. Further works to expand capacity at the nearby Jurong East station and improve turn around times for trains on the North South Line (NSL) resulted in the viaducts creeping closer to the residential blocks near the line. However, there was no convenience gained for the residents as no station was constructed in the vicinity.
