Woodlands - Basic Structure Completion

The final zone of roof slab has been constructed, completing the main structural works at the station. Dismantling of the temporary struts, kingposts, waler beams as well as the striking of falsework are in progress following which the station would achieve the BSC. Structural works for entrance F have also completed to the threshold level - the first among all 5 entrances.

Woodlands Cast (V)

The first section of the roof slab has been cast and reinforcement works for the second zone has almost been completed in preparations of the second pour. Casting works are ongoing at the entrances and crossover tunnel. 2 steel beam launching works for the NSL paid linkway was carried out over the last 2 months.

Woodlands Cast (IV)

Casting of the station's concourse slab is largely completed and works are proceeding up to the roof level. Excavation works at the crossover tunnel site have completed facilitating the breakthrough of the T206 tunnels.

Woodlands Cast (III)

Casting of the concourse level is midway completed across the station box, while excavation works at Entrance F, G and the subway link within the bus interchange have commenced.

Casting works for the station have progressed up to the concourse slab.

Excavation & strutting at crossover tunnel

Woodlands Cast

Bored pile works for the cut and cover tunnel have completed, and the final zone will commence strutting and excavation works. Casting of the skin wall and platform is ongoing at the station.

Woodlands Excavation (V)

Bulk excavation works for the station box have reached the S5 layer and is nearing the formation level. Bored pile works are still being done at the crossover cut and cover tunnel.

Woodlands Excavation (III)

Excavation of the Woodlands station is progressing down to the S2 layer. The completion of the diversion at the Ave2/5 junction in December makes way for the secant bored pile works at the southern portion of the crossover tunnel. The temporary Woodlands Bus Interchange will open next Saturday allowing for the subsequent commencement of A&A works to the existing bus interchange and NSL station for the linkway connection.

Woodlands Excavation (II)

Excavation works have commenced across the station box. Removal of the top soil reveals a coarse ground conditions at a shallow formation. The rock head of the Bukit Timah Granite is extremely high around the site and extensive rock blasting can be expected throughout the course of the excavation works over the next year.

The previously-excavated section of the crossover tunnel has now been decked over in accommodation of the impending traffic realignment of the Avenue 2/5 junction. The remaining half of the crossover tunnel will then be constructed after the diversion has taken place.

The temporary bus interchange is almost ready and on track to open around January.

T203, Woodlands Excavation works

Woodlands Excavation

After a year of piling, the T203 project team have commenced excavation works at the crossover tunnel. Sewer diversion works around the Avenue 2/5 junction are still ongoing and will complete soon. Piling works are now concentrated at the site of the vent shafts and cooling tower on the north end of the station box.

A large amount of rock lies shallowly beneath the T203 project site, and the overall excavation process is envisaged to be one of the slowest among all the projects.

Piling at Woodlands (IV)

Piling works at the Woodlands station have been going on for almost a year now. Sewer diversion works around Avenue 2/5 by the separate contractor are still on going, and we should see preparations for the diversion of the junction by the next quarter for the crossover tunnel construction. The temporary bus interchange is on track to open by year end, with the terminal structure almost completed.

Piling at Woodlands (III)

Piling works continue around the Woodlands site. Utility diversions are still on going around the junction of Ave 2/5, at which the first traffic diversion is expected to be implemented after the next quarter for the construction of the crossover tunnel box. Progress on the temporary Woodlands Regional Bus Interchange under T2211 is included in this update.

Piling at Woodlands (II)

Piling works continue on at the Woodlands site with the 6 Bauers. The rigs are now spread out around the station box away from the crossover tunnel during the initial drilling. The site is viewed from a different angle - Causeway Point in this update.

A road notice has been put up informing motorists of the impending traffic diversions at the junction of Avenue 2/5 for the construction of the crossover tunnel, and a completion only in Q4 2017 when the tunnel is expected to have been backfilled. The diversions however have not started.

Piling at Woodlands

Following the groundbreaking, South Woodlands Drive has seen a road diversion. To date, a total of 7 crawler cranes and 6 piling rigs flood the site. Works are currently being focused on the crossover tunnel which will sit below the existing road junction of Avenue 2/5, hence the need for a future road diversion which can be expected soon after sewer diversions are completed by T2119A.

Under the neighbouring tunnel contract T206, 2 TBMs boring the mainline tunnels from LS2 are planned to dock at this crossover tunnel by the end of next year.

Moving down to Woodlands Central

Moving down south, after curving between HDB blocks and following Woodlands Drive 91 and Woodlands Street 81, the line emerges to Woodlands central. Being an interchange station with the North-South Line, some modification works are necessary at the existing station before construction can begin proper on the Thomson Line station and tunnels.

Into the Woodland

As promised in this update, we will be sharing more about the area around Woodlands South. The tunnel arrangement here will be one of the most complex along the entire line due to the configuration for reception tracks to the Mandai Depot in the vicinity. As such, the authorities dedicated the entire tunnelling works for both mainline and reception tunnels between Woodlands and SBAB to a sole contract - T206. Contract T206 will further interface with another 4 contracts (T201, T203, T205 and T207)

be constructed next to the station as the existing one undergoes refurbishment. The site office is likely for either
contract T203 (TSL Woodlands station) or T2211 (Woodlands temporary bus interchange).

Tunnel Chart for TSL

Here's the tunnel chart organised into two sheets - stage 1 and 2, and stage 3. The exact number for T206 is not known at the moment. A total of 36 TBMs (excluding T206) are set be procured for the entire TSL.
