The Land Transport Authority (LTA) today announced the award of contract CR211 for the construction of Jurong Lake District and cut & cover tunnels on either end of the station to KTC Civil Engineering & Construction Pte Ltd. The contractor is also responsible for Maju station on the Cross Island Line (CRL)'s phase 2 as well, under contract CR206. KTC successfully beat out 6 other contractors that bid for the contract, including 1 that was not shortlisted.

N109A - Teck Ghee update Q2 2024

Road in end-Q2.

Over the past quarter, the major development over at Teck Ghee has been the road diversion of Ang Mo Kio Avenue 6. The diversion saw the roadway shifted further west to allow bored piling works to commence on the eastern side of the site. Along with the road diversion came a re-sizing of the roadway with each carriageway now only having 2 lanes instead of the 3 used formerly. When viewed from an aerial vantage point, the changes are quite apparent.

Tunnel Boring Machines, also known as TBMs, have been described as mechanical moles or earthworms that dig through the ground, leaving behind hollow concrete tubes through which trains eventually run. These huge machines often work their way along the future MRT lines, most members of the public unaware of their existence right beneath them. 

TBMs used on previous MRT projects were huge at approximately 6.3m in diameter. The ones used on the Cross Island Line (CRL) are even bigger, owing to the extra space required to run an additional rail supplying the trains with power along the top of the eventual tunnel. These will measure at around 7.22m for single tube tunnels that carry one track and 12.66m for large diameter tube tunnels that carry several tracks within.

Contract CR206 was the fifth civil contract awarded for the Cross Island Line (CRL)'s phase 2 following the contracts for the large diameter single bored tunnel through the nature reserve, King Albert Park, Clementi & West Coast stations. The award of the contract was announced in end-January this year, with works expected to commence in Q2 of the year. The site has been used thus far for contract CR2016, which is an advanced works contract to relocate utility lines and pipes. The remainder of these works still appear to be going on at the main site of the station's location.

CRL1/CPE/CRL2 - Official Telegram channel listing

With more contracts under the Cross Island Line (CRL)'s phase 2 being awarded, several new Telegram channels have been established to provide residents & stakeholders with updates on construction works. We felt that it was timely to provide a renewed update on the blog as well, for ease of reference should you wish to join the official channels. These groups allow the Land Transport Authority (LTA) and contractors to quickly disseminate information when necessary - for instance, when a road diversion is due to be implemented - allowing stakeholders time to receive the information and understand the changes coming in their vicinity.

As we move into the middle of the year, works along Phase 1 and the Punggol Extension of the Cross Island Line (CRL) have begun picking up as works along Phase 2 begin becoming more visible. Early works for Phase 3 have begun to show as well, with secondary rounds of soil investigation taking place while other contracts begin making appearances on the government tendering portal.
