Tawas station is being constructed under contract J107. Located in a greenfield site north of the Pan Island Expressway (PIE) near Cleantech Park, the station is progressing quickly. The concourse level can be seen being constructed, with the majority of the station's piers already up and ready for the subsequent stage of works. Similar to Gek Poh station across the PIE to the south, Tawas station will sit atop a future road that runs beneath.

While one is able to catch a glimpse of the station's construction from south of the PIE, there do not appear to be many viaduct piers visible from this angle north of the station. Foliage towards the south also obstructs a good view for the time being.

12 March 2023 - Viaduct columns coming up on the site of the former Pioneer Primary School.

12 March 2023 - Most of the viaduct piers are at the rebar installation stage.

12 March 2023 - One of the piers is having formwork installed ahead of casting works.

Across the PIE however, viaduct columns can be seen sprouting up on the site of the former Pioneer Primary School. Work here has progressed quickly since the school was merged with another primary school and its former campus demolished. Now, several viaduct piers stand as the rebar skeleton has been woven together before formwork is installed ahead of casting.

12 March 2023 - A pier with SBGs installed.

of each trackway.

To the north of the station however, several piers can be seen with launching of segmental box girders (SBGs) already being launched. The balanced cantilever technique is being used here, however without the use of lifting frames or hanger beams. Instead, a mobile crane had been used to lift the SBGs onto a platform from which they are joined to the main pier.

The first segments were lifted into place some time in January. Since then, there has been further progress with a total of 4 SBGs launched on either side of each trackway at one pier in particular. Another pier also features 1 SBG on either side of both trackways. 

12 March 2023 - Seen from Nanyang Crescent, this pier has 4 SBGs placed into position on
either side of each trackway.

launching.

It is heartening to see the progress of construction near the Tawas station site. According to contractor Chip Eng Seng - Sembcorp Development Corporation, viaduct launching works are targeted to commence in mid-March further south near Gek Poh station. We look forward to continued progress here near Tawas & further south at Gek Poh in time to come. Do stay tuned for our on-going series on the stages in constructing an elevated MRT line and as we bring you further updates on the progress of construction across the various sites.
