It has been a rather quite time at SGMC since the end of the year due to the multitude of things going on in this author's personal life - lots of assignments for school while still holding down a full time job. Thankfully assignment season is over and we can celebrate a few milestones that we'd like to catch you up on. The first, and most recent one, being the completion of tunneling works for contract CR109.

Contract CR109 is for the building & construction of the Tampines North station along with connecting tunnels to Pasir Ris interchange & contract CR110's Paya Lebar Airbase's Eastern shaft. The westbound tunnel from Tampines North station towards contract CR110 was completed earlier in December 2025. This was followed recently by the completion of the eastbound tunnel on 2 February 2026. With this latest breakthrough, all tunneling works for the contract have been completed.

With the latest breakthrough in early-February 2026, all tunneling works for the contract have
since been completed.

The momentous breakthrough was celebrated with a ceremony held to commemorate the milestone. The guest of honour at the event was local member of parliament, Mr. Baey Yam Keng, who is also Minister of State for Transportation. Here are a few photos from the recent breakthrough event.
