Woodlands South - Basic Structure Completion

The station achieved full basic structural completion with final portion of roof slab cast at the beginning of the year. The remaining concourse and roof slabs have also been constructed at the temporary access pits. RC structural works for entrance B & D have completed, and trackworks have also progressed through the station from SBAB.

The roof slab for the entire station is now completed, with filling works in progress prior to the start of bulk excavation on the south side. Bottom up excavation works for entrance A and C are completed and commencing respectively. Rock blasting works are being done at the concourse level and Entrance B.

All diaphragm wall works have been completed for the project. The final section of roof slab will be constructed at the station before joining the existing bulk excavation works at the north end.

Woodlands South Excavation (II)

The diaphragm wall for the southern zone of the station box and entrance A have been completed and excavation works are underway here. Bulk excavation works for the station are in progress at the completed north zone. The final D-walling works for the project are in progress at entrance C.

The second phase of the d-walling works are underway following the completed stage 3 road diversion.

Woodlands South Diverts (II)

A partial reinstatement of Avenue 1 at the junction of Drive 16 makes way for the remaining diaphragm wall construction at the southern end of the station box. The completed roof slab at the north end of the station is being prepared for the diversion of the remaining stretch of Avenue 1 to complete the 3rd traffic diversion - which will be in place until the completion of the project in 2019.

Woodlands South Cast

The partial basement roof slab of the Woodlands South station is almost completed. Backfilling is underway near the junction of drive 16 around block 542 and 588. The section of roof slab near block 541 is still being prepared to be cast. Following which, we can expect a realignment of Avenue 1 for the remaining permanent top-down construction phase to be carried out.

Preparations for the realignment of Avenue 1 can be expected by the first quarter of 2016.

Woodlands South Excavation

The first phase of the D-wall has been completed on the north face of the Woodlands South station. Excavation works at the S1 layer is in progress. The station will be constructed top-down, and preparations for casting of the roof slab is visible at Entrance D. The next traffic diversion should be implemented by early 2016.

Woodlands South D-walls (III)

D-walling works at the Woodlands South station continues. A section of the completed panel near the junction of Ave 1 and Drive 16 has been shored and partially excavated. The diversion of Avenue 1 can be expected by the next quarter for the construction of the remaining diaphragm wall panels next to Christchurch Secondary.

Woodlands South D-walls (II)

D-walling works continue at the Woodlands South site. 2 piling machines and an additional crawler crane has been added to aid in the construction works from the previous update. We expect expect another quarters of D-walling works to proceed before Traffic Diversion 3 (TD3) gets implemented which involves a final realignment of Avenue 1 that will last through the remaining duration of the project.

Woodlands South D-walls

D-walling works for Woodlands South have commenced following the diversion of Avenue 1. 2 hydrofraise machines are currently executing the trenching works. More bentonite silos have arrived on the site and are awaiting to be hoisted up at the junction of Avenue 1/Drive 16.

Woodlands Avenue 1 Diverts

The third traffic diversion under T205 has been implemented over at Woodlands South this morning. This diversion shifts the existing southbound Avenue 1 closer to Christchurch Secondary, alongside the already-diverted northbound road which had been earlier implemented on Oct 6.

With both carriageways of Avenue 1 fully diverted, D-walling works for the north perimeter of the station will commence in full swing from now. A subsequent diversion of Avenue 1 to the north can be expected in 6 months for the d-walling works on the south perimeter. Upon completion of the ERSS we expect excavation works to begin by the first half of 2016.

Woodlands Drive 16 Diverts

As the existing Woodlands Drive 16 cuts through the Woodlands South site, an interim road has been created to go around the site area. The road however has not yet been opened to public. Works are also underway for another road diversion along Avenue 1. The road will be shifted closer to Christ Church Secondary - this is to facilitate the construction of the station's earth retaining stabilizing structure (ERSS).

Rounding the corner into Woodlands South

Contracto T205 is for the construction of Woodlands South station near Christ Church Secondary School. Since the last update, some more construction machinery has been brought on site and the site office area completed. A retaining wall is to be built within the hoarded up site of Christ Church Secondary to facilitate a road diversion in time to come.

Woodlands South - It's Beginning

Continuing on from the previous update, we have a closer look at the WDS site today. The silos which were seen last month have now been hoisted up while site clearing is still in progress. The actual station box will sit beneath the existing Avenue 1/Dr 16 junction, to the bottom right of the picture.

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)
