CR113 - Serangoon North update Q3 2023

 

21 September 2023 - A view of the station site at the town centre of Serangoon North. Exit 1
will be located there.

The major change that took place over the past quarter was the commencement of diaphragm wall excavation at the Exit 1 site. Located right smack in the heart of the town centre, this will be the site of the main station entrance. Formerly some pile load testing was conducted here before the betonite silos moved in. Subsequently, a hydrofraise machine was also brought in to begin set up. Excavation for the diaphragm wall panels has since begun in Q3 2023.

Further along towards the eastern end of the station is Exit 4, which is located adjacent to Bowen Secondary School. The work site here has made progress with noise barriers being installed and a road diversion implemented. Across the road from the school, work is being carried out with the installation of sheet piles - this may potentially be used as a retaining wall to divert the roadway for the excavation of the station box and mined subway. Over at other sites, preparation has also been carried out ahead of the commencement of diaphragm walling works.

CR112 - Hougang update Q3 2023

 

21 September 2023 - A view of the station box site next to the existing Hougang Central bus
interchange.

Q3 is when things started to get interesting over at Hougang station. The top slab of the tunnel boring machines' (TBMs) launch shaft was cast and excavation works commenced. King posts were being installed at the northern end of the station while diaphragm wall works continued at the south. Over at the west, works began to create the capping beam for an exit. Overall, progress is looking good and the rest of the Cross Island Line (CRL) stations will have to follow suit to catch up.

But first, before we dive into the detailed updates of the various sites, here are some landscape images of the site for your viewing pleasure. These are taken at street level and show the heavy machinery in all their glory.

CR108 - Pasir Ris Drive 1 closure

 

1 October 2023 - A view of the section of roadway before closure.

The past several months at contract CR108 were focused on preparations for the big day where the section of Pasir Ris Drive 1 between the junctions with Pasir Ris Central/Street 51 & Pasir Ris Drive 8 would be closed. That day came on the 8th October 2023, a Sunday. Naturally, traffic would be quieter with less vehicles moving about. We visit the site to find out how residents & motorists were coping with the changes.

CPE - Groundbreaking ceremony

 

This morning, the Land Transport Authority (LTA) held a groundbreaking ceremony for the Cross Island Line (CRL) - Punggol Extension (CPE) section. Spanning 7.3km and adding 3 additional stations to the line, the ceremony was officiated by Acting Minister for Transport, Mr. Chee Hong Tat. Also in attendance were grassroots leaders for the various districts in which works will take place - Mr. Teo Chee Hean (Pasir Ris Elias), Ms. Yeo Wan Ling (Punggol East) & Mr. Janil Puthucheary (Punggol Central).

CR108 - Pasir Ris: The calm before the storm

 

1 October 2023 - A view eastwards of the section of road that will be closed on 8 October 2023.

This update for Pasir Ris will be a special one covering the progress made over Q3 with a little spillover to October 2023 before the major road closure of a section of Pasir Ris Drive 1 between the junction with Pasir Ris Central & Street 51 and the junction with Pasir Ris Drive 8. The road closure will see the roadway reduced to 2 lanes for traffic exiting Pasir Ris to allow motorists to leave the estate and access the expressway and/or Tampines. As a result, bus services will also be affected and diversions will be in effect when the closure takes place this coming weekend on 8 October.

Yesterday the Land Transport Authority (LTA) released a new video flythrough of the Punggol Cross Island Line - Punggol Extension (CPE) station. The video shows the station's four entrances, the eastern concourse area and eastbound platform. The transfer connection to the North East Line (NEL), however, is not shown. This video differs from another one shown by contract P105's contractor Woh Hup at their roadshow.

With the new video released on LTA's YouTube page, we now have flythrough videos of 2 CPE stations at Punggol & Riviera. We can expect that the video for the last CPE station - Elias - should be released some time soon as well.

This is a blog-only post.
