Making headway through our 2024 progress report, we've come to the sixth contract and the final one under the first phase - contract J107. In case you missed them, here are the first five parts of the 2024 progress report thus far:
- Contract J101 for Tengah Depot
- Contract J102 for Choa Chu Kang, Choa Chu Kang West & Tengah stations
- Contract J103 for Hong Kah & Corporation stations
- Contract J105 for Jurong West & Bahar Junction stations
- Contract J106 for Boon Lay station
Contract J107 for the Jurong Region Line (JRL) was won by Chip Eng Seng - Sembawang Design Corporation (CES_SDC) and involves the construction of two stations at Gek Poh and Tawas. Both of the stations will utilise side platform layouts. Significant milestones attained through 2024 have included the completion of casting for all viaduct piers along the contract, the commencement of roof frame installation works at Tawas station and the long span crossing over the Pan Island Expressway reaching the mid-point. We take a closer look at the various accomplishments made in greater detail after the jump.
JW1 - Gek Poh
Gek Poh station is located along Jurong West Street 75, just south of Street 81, directly in front of Gek Poh Shopping Centre - the neighbourhood HDB retail & commercial centre. It serves as a sort of neighbourhood centre. The station is conveniently located along the estate's thoroughfare (and smack in front of one of the team's relatives' home). At the beginning of the year, works were focused on construction of the station's concourse level with the launching of precast crosshead arms and precast beams to form the concourse slab.
By the end of the year, these works had progressed to the platform and trackbed levels instead. A similar process of constructing the platform level crosshead arms was underway while precast beams were lifted into place along the length of the station to form the trackbed. Installation of the beams was approximately 75% complete.

Viaduct construction had also shown significant progress. One of the last viaduct piers to be cast for the contract was located along Street 75. By the year's end, all viaduct piers had been cast, including those across the expressway running through the Jurong Innovation District.

An engagement session was conducted for residents of Gek Poh estate to update them of the upcoming stages of construction. Contractor CES_SDC highlighted that station works were progressing towards roof frame installation, with reinstatement of roads expected in September 2025. Other works that would be commencing as well included track laying works by the track works contractor.

Tawas station has had the benefit of being sited on a greenfield site (a site with no existing buildings or structures, a clean slate). This has allowed the station to be constructed rather quickly, with roof frame installation works underway as of end 2024. In the beginning of the year, the station was only beginning work on the installation of precast trackbed beams and construction of the platform level crosshead arms.

2024 was a productive year for CES_SDC with several milestones attained. 2025 looks to be an exciting year with the likely handover of section of viaduct to the track laying contractor. We look forward to the achievements to be attained in the coming year.
