Site Visit to Bukit Panjang

The land transport authority held a site visit to Bukit Panjang station earlier this morning to announce a first quarter opening date for the Downtown Line 2 in 2016.

September Tunnel Progress

September 15
Earlier this morning, the night shift team at Nishimatsu led S687 to breakthrough the d-wall at Kaki Bukit station, completing the BP bound tunnel between UBI and KKB. This is the third out of 4 TBMs to breakthrough under C929A.

Bukit Timah Road Realigns

Many changes have taken place across the various DTL2 sites over the last couple of days. This dedicated post would consolidate all the new developments.

Newton
One of the most significant milestone in the project timeline, C920 has completed its last phase of traffic diversion at the Newton site - the first DTL2 project to have done so. The slip road has been reconstructed over the backfilled launch shaft ahead of the projected Q4 2014 timeframe indicated on the road signages. Having diverted back the road, land is freed up to construct up the remaining segments of the entrance. Steel frames for the future walkway ramp has begun to form.

Reinstated Bukit Timah Road. Do note that the bus stop location is temporary.

Here is the recently completed escape shaft at Ferrell Residences. The site is temporary hoarded up.

Stevens
C919 will be carrying out one final traffic diversion at Stevens. This is for the hacking of the d-wall located below the existing road. Unlike the initial diversion back in 2011, the presence of the station superstructure now imposes an incredible site constraint. The road has been positioned and surfaced right up to the edge of the structure. The diversion will be carried out this Thursday.

Diversion works

Managed to get a glimpse of the entrance escalators being lowered down prior to road diversion preps as I was walking by the week before. A rare sighting.

Tan Kah Kee
Following the achievement of BSC for the expo bound tunnel to BTN, the final standalone gantry crane for DTL2 has been dismantled at the TKK launch shaft. Backfilling of the shaft will begin at once.

Bukit Panjang

We conclude our 3rd Quarter updates for Stage 2 with Bukit Panjang station. The ventilation shaft structure is complete, while entrance A can be seen forming on the southbound road. Entrance B and the cooling tower is still in its substructure.

The flyover is also beginning to take shape as precast segments are being hoisted and fitted on the north columns. This flyover will be a 2 lane dual carriageway. The southbound lane of Upper Bukit Timah Road has also been diverted slightly towards the west to make way for the superstructure construction of entrance A.

Cashew

At Cashew station, the final road reinstatement will take place in November this year. Like Little India, a secondary hoarding is created within the existing site area behind the original hoarding to prepare for the reinstatement.

Hillview

Alongside Hume, Hillview has almost been completely backfilled. The openings for the future 2 exits and ventilation shafts are prominent, exposing the substructures which have risen all the way up to the surface level. For the entrance along the northbound side of the road, a road diversion would be needed before the entrance can begin to form. It is believed that works will proceed for the flyover to be done first, before the final alignment of the northbound road can be reinstated - allowing for the entrance to form.

Hume

Hume is at its final phase of being backfilled. Road reinstatement could possibly take place early next year.

Beauty World

Vent shaft superstructure at Beauty World is being formed. We should start to see rebar at the entrances' surface by year end.

King Albert Park

Sixth Avenue and King Albert Park are currently trailing behind in progress with casting works still going on beneath the surface. Superstructure of the entrances and vent shafts will not appear until a further 4-6 months.

Sixth Avenue

Sixth Avenue and King Albert Park are currently trailing behind in progress with casting works still going on beneath the surface. Superstructure of the entrances and vent shafts will not appear until a further 4-6 months. As the Expo bound tunnel was competed first, the tunnel has achieved BSC with the first stage concrete, allowing for trackworks to proceed from KAP to Sixth Avenue and ultimately reach Botanic Gardens.
