N109A - Teck Ghee update March 2024

Life kind of caught up to us in Q1, so similar to Tampines North and Pasir Ris East, we only managed to catch Teck Ghee in March 2024. Contract N109A is primarily for the construction of the North South Expressway (NSE) tunnels with the Cross Island Line (CRL) Teck Ghee station added on beneath. As such, the impact at the work site is much greater than that at other station sites due to the cut & cover nature of the expressway's construction.

Work at the junction of Ang Mo Kio Avenues 1 & 6 with Marymount Road has seen several road diversions. The roof slab of a portion of the expressway tunnel was completed and backfilled over. Using the top-down method of construction, works will continue beneath the roof slab internally, with soil being excavated through openings in the roof slab. For the CRL station, works appear to still be focused on boring piles for the earth retaining & stabilising structures ahead of the rectangular tunnel boring machine being used to construct subways connecting to Exits 2 and 3 underneath Ang Mo Kio Avenue 1. Several king posts were also noted on site to be installed and providing support for the horizontal struts and walers during the excavation process.

Meanwhile, along Ang Mo Kio Avenue 6 where the station box is located, works have still been focused on the eastern half of the NSE tunnels. The roof slab of the expressway tunnel has been cast and a layer of crushed stone appeared to have been laid over the top before being back-filled over with excavated soil. Along the sides, it appears that facilities such as pedestrian paths and covered drains were being constructed, possibly hinting at a potential upcoming road diversion that will see the roadway shifted atop the completed sections of tunnel with its roof slab completed. This may make way for subsequent construction within the road median or having the entire roadway shifted to free up the western half of the worksite.

Works at Teck Ghee station appear to be taking an interesting turn with the site being constructed in halves. As time progresses along, we'll be sure to check in and provide you with updates on its progress. Do stay tuned for future upcoming updates!
