Soil Investigation: Defu

Soil investigation spread at the area around Defu as of 05 August 2018.

A stretch of yet to be developed land along Tampines Road is zoned to be an industrial area in the future. This extends the Defu industrial area further north, across Sungei Serangoon from Hougang New Town. A string of soil investigations have been noted from as far back as 2017 along the stretch of road leading from Hougang towards the Paya Lebar Air Base. This is anticipated as the Cross Island Line runs eastwards towards Tampines North and eventually Changi Airport.

In addition to the above boreholes, Soil Investigation rigs were noted by contributor Peter48 around the area (not reflected on above map). We would like to thank Peter48 for the below contributions in helping to note potential boreholes locations. If you happen to see any soil investigation works along the expected route of the Cross Island Line, do feel free to let us know.

This may mean that there may be a station located along Tampines Road to serve the Defu area and subway links may be built from the station to serve residents along the eastern side of Hougang. The tunnels may go under Hougang Avenue 3 in order to link up with the existing North East Line at Hougang town centre. This information, however, is neither official nor confirmed and is based on an educated guess with reference to the available facts.
