Piling at Havelock (IV)

Piling works continues at the Havelock station. The gantry crane has been assembled at the site of the rectangular TBM launch shaft, and on-site casting of the RC ring segments are being carried out. The acoustic screen in front of the Tan Boon Liat building has been completed, and a road realignment to push the carriageways further to the right is being prepared.

Piling at Havelock (III)

Piling works continue at the Havelock station. Acoustic barriers are coming up in front of the Tan Boon Liat building and piling has started at Holiday Inn. The access to Jalan Bt Ho Swee has also been diverted.

Piling at Havelock (II)

Piling works continue at the Havelock site. A temporary retaining wall has been created to counter the uneven terrain between the HDB flats and Zion Road. The piling rigs are situated on the higher elevation next to the flats.

A rectangular CREG TBM will be utilized to construct the pedestrian underpass between the station and the entrances at Havelock Road. DCM works have commenced across Havelock Road where the launch shaft for the TBM is to be located.

Piling at Havelock

Piling works have commenced at Havelock. Minor diversions have taken place to accommodate the temporarily-downsized Zion Road that has been reduced from 4 to 3 lanes. Slope treatment is still on going along the center of the station where sheet piles will be installed.

Havelock Clears

The proposed Havelock Station sits directly beneath a large portion of the Bukit Timah Granite along Zion Road. The volume of rock to be excavated is tremendous; about 180,000 cubic meter of rock is envisioned to be blasted during the excavation of the station - 80% more than that at Woodlands North and 20 times the amount that at Woodlands. As such, we will expect the excavation of the station to be very slow. Similar to Great World, the station will have 3 levels and 5 entrances. Entrances D and E will be linked by an underpass and are located on either sides of Havelock Road. The remaining 3 entrances are located along Zion Road to serve the Bukit Ho Swee estate.

Progress Update

The site office for T221 has recently been completed, and is located at 51A Kim Seng Road. The site is also home to LTA's Thomson Line Civil Team 3's project office. Slope treatments and the felling of trees around the site are underway. 12m high hoardings have also gone up around certain portions of the site.

Package C Renders

 A/E Consultancy services for package C of the Thomson Line were awarded to Aecom and SAA back in 2010. Effectively known as Civil Team 3 as construction works gear up, the design boundaries span from Whitley Road to Havelock. Stations included in this section are Stevens, Orchard Boulevard, Orchard, Great World and Havelock. Napier station is not included inside the design package as it is separately designed by the client.

Contract Awards - T211, T221 & T226

LTA announced on Friday the award of three contracts for Stage 2 and Stage 3. This marks the award of all civil contracts for Stage 2 of the Thomson Line.

Contract T211 is for the design of, and subsequent construction and completion of Sin Ming station and tunnels to both neighbouring stations. Located near Bishan Park and Bishan Park Secondary School, the station will sit in close proximity to existing HDB blocks. This station was awarded to Penta-Ocean Construction Co. Currently, Penta-Ocean is building the Bendemeer station along Downtown Line Stage 3 and also won the contract to construct Woodlands North station along Stage 1. As this contract includes the interior design of the station, there are no renders to show.

Contract T221 is for the construction and completion of Havelock station. Located near the Holiday Inn Atrium hotel, this station will serve the Zion Rd and Havelock Rd area. It is expected to spur redevelopment that coincides with the demolition of the Zion Rd flats. Gammon Construction Limited, which built Chinatown station along Downtown Line 1 and won the contract to construct Mayflower station, will be in charge of this contract.

Contract T226 is for the construction and completion of Marina Bay interchange station. Sitting to the south of the existing Marina Bay Interchange complex which houses the North-South Line and Circle Line, this stacked side platform station will allow commuters to switch between lines easily right in the heart of town. Taisei Corporation, which completed parts of Circle Line stage 4 and Downtown station on Downtown Line 1, has won this contract. Expect long subways at this station when making connections to the existing North-South and Circle Lines.
