CR107 - Pasir Ris East update Q3 2023

 

17 September 2023 - An aerial view of the station work site from the eastern end.

So we're commencing our Q3 updates slightly early with Pasir Ris East up first. Over at the eastern end of the station, works are focused on constructing the diaphragm walls for the launch shaft where tunnel boring machines (TBMs) will be lowered by neighbouring contractor Woh Hup for contract CR106. The TBMs will bore the twin tunnels eastwards, to Loyang station. As such, the launch shaft will be completed under CR107 but subsequently handed over for tunneling works. Upon the completion of tunneling works and first stage concreting, the shaft may be handed back to CR107's contractor, Singapore Engineering & Construction - Sinohydro Corporation Limited joint venture, to complete the remainder of the works.

CR111 - Defu road diversion

Tomorrow, contractor for Defu station will be carrying out further road diversion works along Tampines Road where the station is located. Both carriageways will be diverted further south, with the westbound carriageway utilising a new bridge built over the existing canal. The eastbound carriageway will make use of the existing bridge being used for the current westbound carriageway.

P103 - New video for Riviera

Today, the Land Transport Authority (LTA) released a new video showing a flythrough of Riviera station. Featuring 4 exits, Riviera station will allow tap out-transfers between the Punggol LRT East Loop and the Cross Island Line (CRL) Punggol Extension (CPE). It is interesting to note that the station will feature an upper concourse (B1), lower concourse (B2) and platform (B3) all within the paid area. The station will also feature side platforms as a result of the utilisation of a single large bored tunnel for the line from Elias to Punggol stations.

CRL1 - A snapshot in August 2023

 

Overview of CRL1 stations CR4 - CR13 as at August 2023.
Top (L - R): CR4 - Pasir Ris East, CR5/CP1 - Pasir Ris, CR6 - Tampines North
Middle (L - R): CR7 - Defu, CR8 - Hougang, CR9 - Serangoon North
Bottom (L - R): CR11 - Ang Mo Kio, CR12 - Teck Ghee, CR13 - Bright Hill

Since you seemed to enjoy the snapshot feature on the Jurong Region Line (JRL), we'll give this a try for the Cross Island Line (CRL) as well. With time, the 3 CRL Punggol Extension (CPE) stations can also be featured together with the 6 CRL2 stations in future updates. But that is still some time away as yet. For the moment, here's the snapshot of 9 CRL1 stations as of August 2023.

CRL1 Project Information Centre - now open!

 

29 August 2023 - Operating hours as displayed on the site office hoarding.

Recently, the Cross Island Line (CRL) phase 1's Project Information Centre (PIC) has been opened to the public. Operating hours for the PIC are during weekdays during office hours. Do note that you will need to get in touch with the Public Relations Officer to secure a slot before heading down so that the PIC will be manned during your visit. Not doing so may result in disappointment should the officer be engaged and unable to open the centre for you. Nonetheless, the team paid a visit to the PIC today and are here to relay what you can find once you are there.

CR113 - Construction of an underpass beneath Yio Chu Kang Road

The Land Transport Authority (LTA) released a new video on their YouTube channel today detailing the construction process for the construction of an underpass at Serangoon North station. The underpass will connect Exit 4 to the station box, crossing underneath Yio Chu Kang Road. Located at a graded junction, where Ang Mo Kio Avenue 3 - Hougang Avenue 2 undercross Yio Chu Kang Road which is elevated on top, the works will also need to avoid existing utility lines that cross the intended location of the underpass. Micro tunnel boring machines (mTBMs), smaller versions of their larger cousins, will be used to construct a pipe box which will then be hollowed out to allow for the construction of the underpass' permanent structure.

CR102 - New video from LTA

Today, the Land Transport Authority (LTA) released a new animation video detailing the works required under contract CR102. This contract involves the construction of tunnels between Aviation Park station, the Changi East Cross Island Line (CRL) depot and tracks towards the future Terminal 5 station at Changi Airport. Tunnel Boring Machines (TBMs) will be used to bore 5 tunnels - 2 mainline running tunnels & 3 reception tracks at a T-junction.

According to the video, ground improvement works are required before excavation and tunneling can begin. A further challenge to construction is that it will take place in close proximity to a live aviation environment which limits the height of machinery that can work in the area. However, the contract is being undertaken by Shanghai Tunnel Engineering Co (STEC), who also won contract T316 for works on the Thomson-East Coast Line, also within the Changi Airport area. Thus, STEC should be no stranger to the restrictions of working within a live aviation environment. We wish the contractor well as works get into full swing for the CRL tunnels.
