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.

J102 - Choa Chu Kang

31 July 2022 - A completely cast viaduct pier for the Jurong Pier-bound
track of the JRL.

One of the more notable changes - you can hardly miss it - is the casting of the first viaduct pier north of the station site. Sitting along Choa Chu Kang Loop, next to the existing southbound track of the North-South Line, the pier is just the start of things to come. Foundation works are on-going at the station site proper.

J102 - Choa Chu Kang West

28 December 2022 - An aerial view of Choa Chu Kang Avenue 3 looking
to the south-west. Drainage reconstruction & shifting work is going on.

25 July 2022 - Road diversion completed, freeing up the median for
construction work along Choa Chu Kang Avenue 3. This is also looking
towards the south-west, albeit a bit further towards Choa Chu Kang station.

Road diversions are in place, freeing up the road median for construction work. It took a while to get to this stage, largely due to the sheer amount of preparatory work that was necessary. Entire stretches of drains have been rerouted, constructed and commissioned for use just to get us to where we are right now. At the end of Choa Chu Kang Avenue 3 the drains empty out into a large canal that runs along Brickland Road. As such, the drains along Choa Chu Kang Avenue 3 need to be sufficiently large to cater for all the storm water given the location's proximity to reservoirs.

J102 - Tengah

3 July 2022 - A view of viaduct piers leading to Tengah station, looking northwards. The viaduct
piers are still shrouded in netting.

31 July 2022 - A view of viaduct piers leading to Tengah station. They're now free of their netting.

Initially it was tough to locate this station which is in the middle of an entirely new estate being built from scratch. But we've had our eureka! moment and finally found it. Progress has been swift. Earlier in the month, the viaduct piers were still wrapped up in scaffold and netting. Now some have been unveiled fully cast and works are even progressing to the upper deck level! The upper deck is where the branch to Jurong East will run.

J108 - Tengah Park

19 June 2022 - The beginnings of the platform to enable the segmented box girder to be lifted for
bonding with the pier.

3 July 2022 - Scaffolding now shrouded in netting.

31 July 2022 - The first viaduct segmented box girder sits atop
the pier for bonding eventually.

Back during Chinese New Year, roughly 6 months ago, we stumbled upon the first viaduct piers forming up along Bukit Batok Road here. It was a momentous moment then. Imagine the excitement at seeing that the first segmented box girder for the viaduct lifted into place for bonding to the pier. Upon closer observation, we've noted that the viaduct segment will act as a precast element and will be directly connected to the pier. Some piers will be built to allow bearings to support the viaduct - these will be known as expansion joints which allow the viaduct to contract and expand according to temperature.

31 July 2022 - The larger pier on the Tengah-bound track now
getting the pier head cast. This will allow 4 bearings to be placed
atop, to support the viaduct and allow for contraction and
expansion as necessary.

We've noticed the bigger piers along Bukit Batok Road are now being cast with the pier heads capable of supporting viaducts on bearings. Hence it makes sense that these will support the viaduct in a different manner than the pier with the first segmented box girder lifted up currently.

Works are progressing at an exciting, more visible pace now. We look forward to more milestones being reached as the viaducts and stations begin to take shape.
