J106 - Boon Lay update Q2 2024

16 June 2024 - An aerial view of the new JRL station building and viaducts of contract J106.

Contract J106 for the construction of Boon Lay station and viaducts for the Jurong Region Line (JRL) has seen steady progress at its site through Q2 of the year. Through the quarter, the station building has continued to take shape with the structure rising from the concourse level on the third floor to the platform level on the fourth floor. Eventually, both halves of the station to the north and south of the existing East-West Line (EWL) viaduct will meet above the operational line.


1 May 2024 - A view of the progress of works for the station building as of mid-Q2.

16 June 2024 - A view of the progress of the station building as of end-Q2.

Within the existing EWL station
Works within the existing EWL station have also begun to show, with markings for the relocation of the faregates at Exit D appearing and hoarding for the new staircase connecting the concourse and platform levels going up. At Exit D, the relocated faregates will be arranged in a single row, rather than in the staggered arrangement that is currently utilised. This new arrangement will create a slightly large fare paid area that can accommodate an additional lift to be built.

western end.

13 April 2024 - Multiple markings on the floor for the relocation of faregates.

likely show the new locations of the faregates, moved further towards Jurong Point shopping centre.

New JRL station building
Due to the site's constraints, being situated over a junction and a live railway line, the new JRL station building is being constructed in two halves on the north and southern flanks of the MRT viaduct. The halves are being constructed independently but will eventually join up in the middle, above the EWL tracks. Through the quarter, the building's structure has grown to be a slightly imposing structure next to the Jurong Point shopping centre.

Viaducts
The last section we'll look at is the progress of viaducts along contract J106. Like with the station building, there are 2 main sections where viaduct construction work is taking place. The northern stretch is where the main line runs and connects to the Bahar Junction station, while the southern stretch will be used as over run tracks until phase 3 of the line comes into operation.

Work along the southern stretch has continued to progress with the launching of viaduct segmental boxes using the balanced cantilevered method over the past quarter. At the end of Q2, there were still several gaps to be filled, notably the sections that include the movement & expansion joints, for which the sections of viaduct interfacing with the piers had yet to commence construction.

On the other hand, the northern stretch features approximately 5 movement & expansion joint piers of which at least 2 had begun construction of the associated viaduct spans. Steel supports were used to provide support to the initial set of segments being launched, with subsequent segments added on to balance the load on the bearings of the movement & expansion joints as the spans grew further. In addition, near the northern-most end, parapet wall installation works commenced with the parapet erector being hoisted up onto the viaduct.

It will definitely be interesting to see how the works progress through the third quarter of the year as the viaducts should begin to reach completion. As the length of viaduct to be constructed is short in comparison to other contracts, the work should progress somewhat quicker, potentially overtaking the progress levels of other contracts. Do check back for updates some time soon!
