Construction progress at T302

As the Land Transport Authority (LTA) recently announced the addition of Founders' Memorial station, it was mentioned that the construction of the new addition would begin in 2019. This statement was misleading as Founders' Memorial station was being partially constructed as an interim facility building as a future, unopened station on the line under contract T302. It was subsequently added that this would be done by converting a planned facility building into an operational station.

Project Information Centre for East Coast Line

As is common practice for all rail lines being constructed, a Project Information Centre (PIC) has been established for the East Coast section of the Thomson-East Coast Line (TEL). The PIC also covers Xilin station's construction on the Downtown Line (DTL) extension and the Tanah Merah Modification on the East West Line.

Constructing Katong Park

Along with the formal announcement of Founders' Memorial station, the Land Transport Authority yesterday also provided an update on the construction of the Thomson-East Coast Line (TEL). In particular, a more in-depth look at the construction of Katong Park station was provided.

We understand that the Katong Park station will be of a stacked configuration whereby the upper platform level is shared with the concourse, similar to Stevens station on the Downtown Line. However, unlike Stevens station, passengers will be able to switch between platform levels without the need for tapping out of the system.

Faregates are visible at both ends of the station.
According to LTA, excavation of the station could not progress until the tunnels for the station had been bored through. Tunneling from contract T305 involves launching the tunnel boring machines (TBMs) from a launch shaft abutting contract T303 near the Singapore Swimming Club, in the vicinity of the Kallang-Paya Lebar Expressway crossing. The TBMs will make their way from the launch shaft, through Katong Park station and emerge at Tanjong Katong (formerly named Amber) station where they will be dismantled.

Typically, when boring stacked tunnels, the lower tunnel is mined first followed by the upper tunnel. When approaching a station, the tunnel breaks through a portion of the retaining wall. If the station is at a sufficiently advanced stage of construction, the TBM can be pulled or pushed across the track bed at platform level to commence tunneling from the other end of the station.

Occasionally, station construction is not this advanced, particularly in tight sites where the top-down construction method is used. This would require the TBM to continue tunneling through the station box even after breaking through the retaining wall. The tunnel rings used during this portion of the drive may be concrete rings that are demolished subsequently or steel rings that are used to retain the shape of the tunnel. Such a technique was formerly used on the Circle Line during the construction of Buona Vista station, where the TBM tunneled through the station box and the temporary rings were later removed as station excavation progressed down.

The below video shows the launching of the TBM from the launch shaft along Tanjong Rhu Road in September 2017.

As both the upper TBM boring the Changi-bound tunnel and the lower TBM boring the Woodlands-bound tunnel have passed through the station box, they should be well on their way to Tanjong Katong station for their final breakthrough. As the distance for this portion of the drive is about twice a long, it can be expected that the duration of tunneling would take twice as long as well.

Gardens Bay East renamed to Founders' Memorial

We have previously touched on a station located between Tanjong Rhu and Gardens by the Bay stations on the East Coast stretch of the Thomson-East Coast Line (TEL), known as station E1 during the planning stages of the Eastern Region Line. The then working name of the station was Gardens Bay East, which has now been officially renamed as Founders' Memorial today, as announced by the Land Transport Authority.

Station renders

The consultant in charge of the Electrical & Architectural design for a stretch of the Thomson-East Coast Line from Gardens Bay East up to Marine Parade has recently released the first render of the station. Featuring entrance A which is situated in the park, DP Architects describes the design as "been developed with the concept of integrating into Garden’s Masterplan including the station entrances, cooling tower and vent shafts". Numerous water features can be seen in the render allowing the station entrance to blend into the lush green of the park. It is learned that the station may eventually open together with the rest of the stations along the East Coast stretch of the line. For renders of the other stations, do continue beyond the jump.

Construction Progress

In May, we did a short drive around to get some videos of the construction progress along the East Coast Line. Do check out the video we have created below.

Stay tuned for more updates in the coming months as construction ramps up at the various station sites.
