J103 - Corporation update Q3 2023

 

16 September 2023 - A view of progress at the station at the end of Q3 2023.

Hey there, thanks for putting up with the team being on vacation the last few days. It's been good to have a bit of a break and for the majority of the time we'd been on vacation had scheduled posts in our absence. But we're ready to get back into our regular quarterly updates and with an upcoming November snapshot in a few weeks' time, so do get ready for those.

Today we're looking at the progress made at contract J103's Corporation station. To date, the Land Transport Authority has not confirmed the station names or put them up for voting/suggestions as they had done with other lines previously. We're wondering if they will be doing the same for the Jurong Region Line (JRL) and Cross Island Line (CRL), or if they will ultimately simply decide on the names themselves. The last round where members of the public got to vote for or suggest station names was on the Circle Line stage 6 (CCL6) back in 2017 - 6 years ago.

Nonetheless, the lack of a confirmed station name has not hindered progress over at Corporation station's site. Over the past quarter, work has progressed to finish up the majority of the concourse slab with works beginning on the concourse level columns towards the end of the quarter. Viaduct piers on either side of the station were also in progress, with the viaduct segment launching taking place on the eastern side of the station. Preparation works were being undertaken ahead of the launching gantry's eventual installation atop the piers as well.

July 2023
In early-Q3, work was focused on building up the concourse level slab between the completed station piers. Further along, viaduct piers were being constructed near the exit ramp from the Pan Island Expressway (PIE) and along Jurong West Avenue 2.

August 2023
Construction at the station site was still focused on getting the beams installed for the concourse slab. At the viaduct sections, construction was still underway for additional piers while others were closer to completion with the casting of the crossheads completed. During this month, the Public Utilities Board (PUB) had to conduct urgent water mains rectification works at the junction between Corporation Road & Jurong West Avenue 2. As such, marshals were deployed to direct traffic at the increasingly complex junction.

ramp.

Corporation station is making steady progress, especially when compared to the progress over at its sister station - Hong Kah - across the expressway. The viaduct piers have started to pop up and this should pave the way for speedier construction when the piers are completed and ready for the launch gantry to begin assembling viaduct spans. We look forward to the continued progress and will update on developments in Q4 as we close off the year with a major update. Stay tuned till then!
