CPE & CRL2 - year-end update 2023

 

The 9 station sites of CPE & CRL2 as of end-2023.

2023 was an eventful year for both the Cross Island Line (CRL)'s Punggol Extension (CPE) & Phase 2 (CRL2) sections with the ground breaking ceremony and contracts being awarded respectively. With the ground breaking ceremony taking place this year, work has began at all 3 station sites under the offshoot branch which connects the main CRL line at Pasir Ris with Punggol - a precursor to the long spoken about Northshore Line which would have eventually connected Punggol and Woodlands. Over at CRL2, contract awarded began, with 3 of the 9  civil contracts awarded through the year. All in all, 2023 has been exciting for the phase 2 stations.

CRL1 year-end update 2023

 

10 stations of the Cross Island Line's phase 1 as at end-2023.
Aviation Park & Defu are not represented in this post.

Sorry this post was a little delayed - got caught up between travelling & work. But we're here and made it to 27th December after all. For this post, we're covering the 10 stations that we have the most pictures of along the Cross Island Line (CRL)'s phase 1. The 2 stations not covered in the post today are Aviation Park and Defu. We may cover them at a later time. Nonetheless, it has been an eventful year for the CRL with the groundbreaking ceremony being held in January 2023. Construction has been well under way at all sites with work in full swing for the construction of the earth retaining & stabilising structures (ERSS). Several intermediate launch shafts have been built as well and excavation commenced at a few sites in particular.

Please be fair warned that this post is a mega-post and extremely photo-heavy. It may suck up a lot of your bandwith after the jump.

Today, the Land Transport Authority (LTA) announced the award of contract CR209 for the construction of West Coast station & associated tunnels under the Cross Island Line phase 2. Contract CR209 is the fourth contract under phase 2 to be awarded - the other contract being contract CR202 for the large diameter tunnel through the Central Catchment Nature Reserve and contracts CR205 and CR208 for the construction of King Albert Park and Clementi interchange stations only respectively.

N109A - Teck Ghee update Q3 2023

19 August 2023 - Installation of rebar visible within the excavated trench.

Work at Teck Ghee station's site is progressing with the excavation of the western half of the tunnels for the North-South Expressway underway. Looking at the work taking place, it may be likely that the structure on the western side will be completed before earth is back-filled on top of the roof slab and work begins on work for the eastern half's structure. At this point, Ang Mo Kio Avenue 6 which travels right on top of the future tunnels has been pushed to the eastern side to allow for sufficient space to create a work site on the western side which is where the tunnels are being constructed.

Here's a look at the progress made at the various Cross Island Line (CRL) sites across Phases 1, 2 & the Punggol Extension in October 2023.

CR116 - Ang Mo Kio update Q3 2023

 

19 August 2023 - A view of the progress of construction around the existing North-South Line
(NSL) Ang Mo Kio station.

Over Q3, works have progressed at the Ang Mo Kio station site. Significant progress has been made at the launch shaft site as well as several exit worksites where diaphragm wall excavation works have commenced. Soil treatment work is also being carried out at Exit 8 ahead of excavation there.

CR115 - Tavistock update Q3 2023

 

21 September 2023 - A view of the road diversion implemented for Ang Mo Kio Avenue 3 at
the site of Tavistock station.

Over Q3 2023, road diversions have been put in place at Tavistock station and more machinery has moved in to the site. With works in full swing, diaphragm wall excavation is due to commence in mid-Q4 2023. We take a closer look at the progress made over the past quarter in this post.

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).

CRL1 - A snapshot in September 2023

Our snapshot update for the Cross Island Line (CRL) phase 1 in the month of September 2023 is here. We have also begun the Q3 updates for some stations, so those updates will be more detailed than the ones reflected here. Nonetheless, do enjoy the brief update on the 9 contracts for September.

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.

P105 - New video by LTA

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.

CRL2 - Contract awards for CR205 & CR208

The second phase of the Cross Island Line (CRL) achieved a milestone today with the award of 2 contracts - CR205 & CR208. The contracts are for the design & construction of King Albert Park and Clementi interchange stations respectively.

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

 

20 September 2023 - A map depicting the changes to the road layout.

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

 

Source: LTA

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.

This post is only available on the CRL Construction Blog & will not be cross-posted to Instagram.

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

 

Source: YouTube

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

 

Source: YouTube

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.

Image by Shanghai Tunnel Engineering Co.

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.

CR108 - Pasir Ris update Q2 2023

24 June 2023 - A newly expanded ticketing hall at Pasir Ris East-West Line (EWL) station.

 "Pasir Ris is one big construction site", was how Member of Parliament Mr. Teo Chee Hean described the ongoing works to build infrastructure to bring more benefits to residents of the town. When passing through Pasir Ris Central, this certainly looks to be the case. The future Pasir Ris Cross Island Line (CRL) station will become the deepest MRT station upon completion - beating out stations such as Raffles Place (the deepest station on the initial 1990's network), Bras Basah, Promenade and Bencoolen - reaching almost 50m deep. Not only is the station the deepest, but the construction site is also likely one of the longest stretching from Sungei Tampines up to the area in front of block 570 along Pasir Ris Drive 1 as there will be crossovers located within cut & cover tunnels on either side of the station. The tunnels to the east especially allow for the tunnels on the lower level connecting the line to Punggol to rise to meet the mainline CRL tunnels.

CR115 - Tavistock update Q2 2023

 

29 June 2023 - A view of the station site looking eastwards along Ang Mo Kio Avenue 3.

The landscape over at contract CR115 for the construction of Tavistock station and tunnels linking to both Ang Mo Kio & Serangoon North stations has changed dramatically over the last quarter. Trees have been felled to make way for upcoming works while noise barriers have sprung up close to the landed properties and JTC block fronting Ang Mo Kio Avenue 3. In addition, a petrol station at the junction with Ang Mo Kio Industrial Park 2 has been vacated to facilitate the upcoming works.

P102 - Analysis of Elias station's location & tunnel alignment

 

Requirements for Wafer Fab industries restrict the line from travelling too close.

We've received some questions on why Elias station must be located at the angle & location that was ultimately chosen. As such, we have done up some visuals and an analysis to help you better understand the factors that play a part in choosing a location for the station.

CRL2 - Release of contract CR203 for Turf City

 

24 July 2023 - Tender for contract CR203
Source: LTA

Today, the Land Transport Authority (LTA) floated the tender for contract CR203. This contract involves the construction of Turf City station and associated tunnels connecting to King Albert Park station in neighbouring contract CR205. Contract CR203 is the sixth contract floated for tender under the Cross Island Line's (CRL) phase 2 which continues the line from Bright Hill to Jurong Lake District. CRL2 is due to commence operations in 2032.

To date, of the contracts floated for tenders, 1 has been awarded, 3 have been closed for evaluation of tender bids & 2 remain open. We've done up a table for ease of reference.

Contract Number	Status	Bidders

With the latest tender floated, the contracts for 5 of the 6 stations along CRL2 have been successfully tendered. The remaining contract for Jurong Lake District station has yet to be floated, along with 2 other contracts - likely to be contracts for tunneling works. The remaining contracts are numbered CR207, CR210 & CR211.

This post is also available on Instagram & Facebook.

P102 - Elias MRT town hall

 

Yesterday, the Land Transport Authority (LTA), together with grassroots leaders and joint venture partner CES_SDC & Chip Eng Seng Contractors held a town hall meeting for residents at Elias Community Club to brief residents about the Elias MRT project. The guest of honour for the town hall event was MP for Pasir Ris West, Mr. Teo Chee Hean.

CR117 - Bright Hill update Q2 2023

 

29 June 2023 - A view of the Thomson-East Coast Line station exit with contract CR117 work
ongoing behind.

Penta Ocean's back in Bright Hill - formerly the contractor for contract T211 to construct Bright Hill Thomson-East Coast Line (TEL) station and now the contractor for contract CR117 for the Cross Island Line (CRL) portion of the station. Over the past quarter, the work site has moved from a preparatory mode into one of proper construction. Site set up seems to have been completed and work is underway for the diversion of drainage lines. Works at the site have also involved a small road diversion and more equipment for the commencement of bored piling has turned up on site.

CRL1 & CPE - Official Telegram Channels

 

Telegram groups have become the new means through which the Land Transport Authority (LTA) has digitised its outreach to stakeholders with new rail projects. The messaging platform has been used as a uni-directional channel through which circulars and updates on the various construction contracts are pushed out to residents, businesses and commuters in the area where construction works are taking place. The first wide-spread adoption was undertaken by the Circle Line Stage 6 (CCL6) project and subsequently adopted by the Jurong Region Line (JRL) as well. It appears that the Cross Island Line (CRL) is using this as well. We attempt to consolidate the links for you to join the Telegram channels as well, which have been rolled out for CRL1 and CPE sections, for which all civil contracts have been awarded thus far. It is assumed that the same will follow for CRL2 once the contracts have been awarded and for CRL3 in due time as well.

N109A - Teck Ghee update Q2 2023

 

10 June 2023 - A view of excavation work being carried out within the construction area.

Contract N109A, under the North-South Expressway project, also includes the construction of a station box for the Cross Island Line (CRL) below the road tunnels. Utilizing the width of the excavated trench, the station will feature cripple sidings that run parallel to the platform - similar to those found at Fort Canning and Mattar stations along the Downtown Line. Work is progressing with excavation of part of the trench having commenced at various portions of the site. We are unsure if this is to facilitate the construction of the roof slab for a top-down construction method to be used later on.

CR113 - Serangoon North update Q2 2023

10 June 2023 - A view of the construction sites at Serangoon North.

 Over at contract CR113, work has been picking up speed with the preparation of several sites completed and moving onto site set up with equipment being moved in. This contract is for the construction of Serangoon North station and does not involve any tunneling works, which will be carried out by neighbouring contracts CR112 to the east and CR115 to the west. The station itself occupies a fairly long site, with the eventual station stretching for about 700m, it is undoubtedly one of the longest stations and will involve a complex construction.

P105 - Punggol interchange roadshow

 

24 June 2023 - Renders of new entrances to be added north of Punggol Central.

The Land Transport Authority (LTA) & contractor for contract P105, Woh Hup, is holding a roadshow exhibition at Punggol station today. Situated next to Exit A, it is right where the station connects to Waterway Point mall. If you're in the vicinity, they're there till 8pm today, so there's still time to head on down and check out the exhibit. You might be able to get a magnet souvenir as well, provided that there's still stock available.

CR111 - Defu update Q2 2023

 

15 June 2023 - An aerial view of preparations for road diversions along Tampines Road.

Contract CR111 for the construction of Defu station and associated tunnels was won by the joint venture of Gamuda & Wai Fong. The contract will involve the completion of the Defu station located underneath Tampines Road and twin bored tunnels to Hougang station, the next stop westwards. As contract CR111 was one of the later awarded contracts for the Cross Island Line (CRL), works have been focused on site preparation till recently.

CR151 - Contract awarded for 44 electric trains

Today, the Land Transport Authority (LTA) announced the award of contract CR151 for 44 train sets to CRRC Qingdao Sifang. The contract also includes an option to purchase 11 further train sets. Initially formed of 6 carriages, the trains can be further lengthened to 8 carriages in the future. Here are some of the features unique to the Cross Island Line (CRL) trains:

• Starting capacity with 6-cars per train set
• Future scalability to 8-cars per train set
• Powered via an overhead catenary rail (OCR) - essentially a third rail but affixed to the tunnel roof and capable of transmitting higher voltage
• Wider carriage-to-carriage gangways than available on currently existing trains at 1.6m instead of 1.4m

We had previously posted an image from a presentation showing the large diameter single bored tunnel which showed the inclusion of OCR support equipment within the tunnel. In addition, early renders of the Changi East depot also showed the presence of OCR masts within the depot area.

CR116 - Ang Mo Kio update Q2 2023

 

10 June 2023 - Construction of the capping beam for the launch shaft.

Contractor Gammon is not new to the Ang Mo Kio area, having completed the nearby Mayflower station on the Thomson-East Coast Line along Ang Mo Kio Avenue 4 several years back. For the Cross Island Line (CRL), the contractor is back & teaming up with veteran Bachy Soletanche to undertake contract CR116 for the construction of Ang Mo Kio station and tunnels connecting to Teck Ghee station to the west. Quarter 2 of 2023 has been a busy period for the contractor with works ongoing to prepare the site for the oncoming structural works necessary to build the station. We'd like to thank our Instagram follower @linhsu88 for providing us with some images to use in this post as well.

CR112 - The beginning of CRL excavation (Hougang Q2 2023)

 

2 June 2023 - Excavation at the northern end of the site with completed diaphragm walls.

Contract CR112 was one of the first civil contracts awarded for the Cross Island Line (CRL) phase 1. As such, it is also one of the first contracts to have commenced excavation works with a portion at the northern end of the station site having soil removed within an area where diaphragm wall works have completed. Join us as we bring to you an update on work progress as of the second quarter of 2023 at Hougang station.

CR2016 - Advanced works for CRL2

Recently if you've travelled along Clementi Road, especially around the Singapore Institute of Management (SIM) / Singapore University of Social Sciences (SUSS) stretch, you may have noticed green hoarding along the boundary of the road. Ever wondered what the hoarding is for? Could it be that works for the Cross Island Line (CRL) phase 2 are already beginning? Find out more after the jump.

P105 - Punggol Q2 2023 pre-construction update

 

Information on Punggol CPE station by Minister Janil Puthucheary

New posts from Minister Janil Putucheary, MP for the Punggol area, indicate that works for Punggol station on the Cross Island Line - Punggol Extension (CPE) are due to begin this month. Work will commence for setting up the contract P105 site office and CPE Project Information Centre (PIC) that will be located next to My First Skool some time this month. Next month, hoarding will go up for several sites along Punggol Central as well.

CR106 - Loyang Q1 2023 update

 

30 March 2023

Under contract CR106, a section of Loyang Avenue between Pasir Ris Drive 3 and Loyang Way was closed on 26 February 2023 to facilitate the construction of Loyang Cross Island Line (CRL) station and a vehicular viaduct on top. Since the closure in late February 2023, the work site has been cleared of trees and heavy equipment had moved in.

CR107 - Pasir Ris East Q1 2023 update

 

30 March 2023

Our last update for Pasir Ris East station under contract CR107 was at the end of 2022. We made a visit right at the end of Q1 2023 and are ready to present to you an update of the site. Since the road closure of a stretch of Pasir Ris Drive 1 between Pasir Ris Drives 2 and 4, work has taken over the former roadway. 

Various activities are taking place along the entire stretch with the arrival of hydrofraise frames and a clam shell grabber machine to facilitate diaphragm wall works. There do not appear to be betonite slurry silos or a treatment plant on site yet, hence it is unlikely that these works will begin so soon.

Meanwhile, works for the base of the eventual 10 to 12 metre tall noise barriers can be seen. Concrete bases have been built at various locales, but the installation of the barrier has yet to begin. Photos available after the jump.

CRL1 - New videos

 

The Land Transport Authority (LTA) today uploaded a new video showing a flythrough of the upcoming Bright Hill station, the western terminus for the Cross Island Line (CRL) phase 1 which is due to open in 2030. An interchange station with the existing Thomson-East Coast Line (TEL), provisions were made during the former's construction to allow paid linkways to connect to the future station and also for the future line's tunnels to cross over the existing station structure. We've extracted several screenshots from the flythrough video after the jump for your browsing pleasure. Additionally, we have also collated some other videos that LTA has posted up since our last update in March. All are available after the jump.

CR108 - Pasir Ris Q1 2023 update

 

30 March 2023

After the update on Bright Hill in the west, we swing back to the east with a whopping update on Pasir Ris. Works are in full swing with diaphragm walling works commencing in the west and soon to commence in the east of the site as well. Road diversions have been completed and an upcoming long-term road closure is in the works.

CR117 - Bright Hill Q1 2023 update

 

19 March 2023 - An overview of the eastern end of the contract site.

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.

CR109 - Tampines North Q1 2023 update

 

30 March 2023

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.

30 March 2023 - A view of the station site from the south.

30 March 2023 - A close up view of the heavy machinery towards the middle of the station box.
