Soil Investigation: Gul Circle

Spread of soil investigation boreholes along Gul Circle as of 18 June 2018.

Near the newly opened Gul Circle station, a string of soil investigation boreholes line the road after which the MRT station along the East West Line obtained its name. The boreholes seem to have largely been dug over several months in 2017 stretching from one end of Gul Circle near Tuas Road all the way to the other end near Benoi Road.

Starting near the junction with Tuas Road, the first borehole is located fairly near to the existing station in front of Isola. As of 18th June 2018, the company has since vacated the premises and the compound lies empty which may free up land for station infrastructure to be built.

 Moving westwards, the boreholes continue along Gul Circle, mostly keeping to one side of the road.

On occasion, a borehole happens to be located on the opposite side - such as the one below located outside 11 Gul Circle.

Beyond the junction with Gul Way, soil investigation rigs were still visible on 1st September 2017. These were located in a row towards the end of Gul Circle near Benoi Road.

As of 18th June 2018, the boreholes were completed and the rigs no longer visible along Gul Circle. All that is left are remnants of where the drilling had occurred and markers indicating that the project for which the boreholes were created belong to the Land Transport Authority (LTA).

In case you were wondering why these borehole markers are important - it is mostly due to the fact that they contain important information.

Soil investigation in Clementi stating that project ER463 is for Soil Investigation works
for LTA stretching from Tuas to Changi.

Based on previous information, it is evident that contract ER463 stretches from Tuas to Changi, which is the route of the Cross Island Line (CRL). Hence it is likely that any boreholes under this contract would be related to the alignment of the CRL. As always, should you see any soil investigation works, do let us know so that we may compile any data that we may miss out.
