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.

being bonded ahead of viaduct construction commencing.

02 October 2022 - A view with the next set of piers included which have
bases for bearings to be installed. These are likely to be the expansion
joints for the viaduct which allow the expansion and contraction to occur.

Since the first piers went up in February 2022, more have been added at the site. Recently, two piers with bases for expansion joints were topped off. This is likely a key to allowing viaduct construction to commence as there is a now a continuous stretch of 3 piers which allows for the construction of 2 viaduct spans minimally. A viaduct span refers to a section suspended between 2 piers.

station in the background, taking shape.

Further piers towards Tengah Plantation station are also rapidly taking shape. Some have been completely cast whilst others are partially cast or beginning with the rebar skeletons. It is also likely that some of these piers will be built to support two bounds of the viaduct, having pier crossheads that extend outwards like two arms reaching out to hold the viaducts up.

girder and the launch gantry which has been assembled next to it.

The launch gantry that had arrived on site a few months prior has since been assembled into a single structure that is longer than 2 standard spans of the viaduct. It will likely resemble the launch girders used to construct the Tuas West Extension previously. The launch gantry is likely to allow segmental box girders to hang from below for final adjustment and positioning in order to construct the viaduct.

02 October 2022 - A pier with the rebar skeleton being constructed. The green equipment lying
nearby are the moulds which will shape the concrete into its final form, giving the pier a shape.

02 October 2022 - A close up view of the same pier.

02 October 2022 - Another 2 piers whose bases appear to be complete. Now for the upwards climb.

02 October 2022 - Yet another pier whose based is completed.

02 October 2022 - A close up view of the completed base. The sheet piles used to retain the soil
for excavation of the foundation piles have been extracted and removed as well.

02 October 2022 - Towards the south (Bukit Batok West station), another pier has its foundation
piles completed and the base is under construction. This pier may support several track bounds
as there may potentially be a cripple siding located here.

Towards Bukit Batok West station, the signs of several piers under construction are visible - again in various stages. One of the furthest along on this stretch has the rebar skeleton rising up with concrete moulds placed nearby. We look forward to the continued visible progress on this section of the line and eagerly anticipate the beginning of viaduct construction - another milestone in the construction of the JRL.
