A number of boreholes and soil investigation rigs were spotted along Loyang Avenue in 2017. These stretch from the intersection with Pasir Ris Drive 3 near the Loyang Bus depot all the way to the SIA Engineering compound. Some of the boreholes were noted to date back to 2016.

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.

Following Soil Investigations in Clementi from 2016, we have also noticed Soil Investigation rigs around King Albert Park station in 2017. The rigs took turns at drilling along various points along Blackmore Road through August & September 2017.

Soil Investigation: Clementi

The spread of Soil Investigations within Clementi as of 02 June 2018. The dates represent the dates the boreholes
and/or Soil Investigation works were seen and/or officially completed.

As work on the eastern leg of the Cross Island Line (CRL) ramps up, Soil Investigations along the western leg begins to show patterns of study. As can be observed within Clementi over the period of approximately 2 years, a number of boreholes have surfaced showing a possible route alignment option that has been pursued for further study.
