Making tunnelling safe

Bore hole sampling at the site of the Pasar Rakyat MRT station two years ago. Bore holes provide valuable information for geotechnical engineers, who also try to glean as much information as possible about the underlying strata of areas between two bore holes using geophysical surveys. -- MGKT

Building the Klang Valley MRT has reached a vital stage under busy Bukit Bintang.

THERE is only one more year to go before the tunnel-boring work of the Klang Valley MRT’s Sungai Buloh-Kajang line (SBK Line) concludes. By the end of this year, only two tunnel-boring machines (TBMs) will still be mining, and the last unit is set to be retrieved from the ground in May 2015.
