To complete our Q1 updates of the Jurong Region Line (JRL), we're at Nanyang Technological University (NTU) where the line's northern section of phase 3 is located. Consisting of 2 contracts covering 3 stations, this section was awarded entirely to Hwa Seng Builders, greatly simplifying the works required by using only a single contractor for the entirety of the works. Equipment can be shared and the contractor can better control construction traffic entering & exiting the university.
JW3 - Nanyang Gateway
West of the first station under contract J113, viaduct construction has begun in earnest with the commencement of viaduct span construction outside Hall 8. Here, the line navigates downslope as it descends one of the many hills within NTU. At the end of Q1, span construction works were just beginning using lifting frames under the balanced cantilevered assembly method.

The first station, Nanyang Gateway, is located between Hall 10, Nanyang Grove and the North Hill hostels. Over the past quarter, work was largely focused on the foundations of the station. Several caissons were dug where the eventual station pier columns would sprout from.

To the east of the station, various viaduct piers were under construction to connect to adjacent contract J107. Casting for the piers here started off with the columns and crowns, with the piers closest to the contract boundary being the first to proceed to crosshead casting. These works subsequently pushed closer to the station over the quarter.

JW4 - Nanyang Crescent
Continuing off near the School of Art, Design & Media (SADM), the viaducts cross over Nanyang Drive twice to run along the base of the hill where a Public Utilities Board service reservoir is located. This stretch was the first under the phase 3's northern section to commence viaduct span construction in end-2023. As the line here is barely elevated off the side of the hill, the trestle method was used for span construction with segment boxes being lifted into position by a mobile crane. By the end of the quarter, significant spans of the viaduct were completed even as work progressed on the construction of further viaduct piers.

The station building saw excavation continue to clear the required area for the lower concourse and platforms to be constructed. By the middle of the quarter, the perimeter wall formed by secant bored piles had become exposed. Bored piles that would form the station building's foundation were also unveiled, allowing for the station structure to be built above even as excavation work continued.

JW5 - Peng Kang Hill
The final station within NTU, and the last to be awarded under contract J115A, is located at the south-western end of the university campus. Sited on a slope, the station is partly at-grade and partly-elevated, similar to neighbouring station Nanyang Crescent and will also feature lower and upper concourse levels. Work at the station site has been ramping up over the first quarter of the year with the noise barriers at the site being installed.
To the north of the station, caissons were excavated in which bored piles were constructed. These would serve to support the viaduct columns as the viaduct traversed a slight valley before reaching the station.

With sections of the line within NTU commencing viaduct span construction, almost all phases of the line have begun construction of the viaduct spans in some way or form. Only phase 3's southern section was left to begin viaduct span construction, just as the rest of the phases along the JRL had begun. Do stay tuned as we're about to launch into our Q2 updates of the line shortly once we're a wee bit more into the month.
