Contract CR117 was the last civil contract awarded for the Cross Island Line (CRL) phase 1, hence progress at the site is not as advanced as at other contracts awarded earlier, for instance Pasir Ris or Hougang. None the less, the site appears to have been cleared and preparatory works underway to commence earthwork for the construction of retaining walls.

We begin swinging to the eastern end of the Cross Island Line (CRL) phase 1, starting at Tampines North. The site has since been cleared and diaphragm wall works have commenced at the northern end of the station. Meanwhile other preparatory works are still going on further south in the station box.

It is great to see that diaphragm wall works have commenced at another station site besides Hougang station. Do stay tuned as we continue to provide updates on the different sites along CRL1.

Teck Ghee was the first station whose civil contract was awarded under contract N109A, which was bundled together with construction works for the North-South Expressway project. The expressway tunnels will eventually sit on top of the station's roof slab, with the concourse & platform located below. We checked out how things were progressing at the contract N109A site mid-March.

On 19th March, the team took some time to visit a few of the Cross Island Line (CRL) phase 1 sites to check in on how the sites have progressed. Similar to the updates on the Thomson-East Coast Line (TEL) stages 4 and 5, we hope to do the same for the CRL 1 stations. We've kicked it off with some updates on Hougang and contract CR115's launch shaft, so here's an update for Ang Mo Kio.

Recently the tunnel boring machine (TBM) for contract CR105 underwent its factory acceptance test (FAT). The FAT is where the client, in this case Taisei Corporation - China State Construction Engineering Corporation Joint Venture, goes to the manufacturing factory to see that the machine meets their expectations after production has completed. A series of tests are conducted to ensure that all is in order before the machine is disassembled for delivery to the client's project site.

It's been a while since we've had an update on the Cross Island Line (CRL), so we're at Hougang this week to kick things off. Work at the northern half (the closed section of Hougang Central Minor) is more advanced than that at the southern half (near existing Exit A, next to the bus interchange) of the site.
Yesterday, the Land Transport Authority (LTA) released a video showing a flythrough of the upcoming Tampines North station along the Cross Island Line (CRL) phase 1. LTA has been noticeably more active in uploading videos of & marketing the CRL across its social media channels. In addition to the new video on Tampines North, they also uploaded another video on the Rectangular Tunnel Boring Machine (RTBM) being used at the Teck Ghee station under contract N109A to construct subways to two exits located within Bishan-Ang Mo Kio park.
