Dr Ooi Lean Hock

Ir Dr Ooi Lean Hock holds a PhD in geotechnical engineering from the University of Sydney, Australia. In the past, he has served in various capacities in the Institution of Engineers, Malaysia Council and Geotechnical Technical Division, and the Malaysian Site Investigators Association. He is currently seconded from Gamuda Bhd to KVMRT (T) Sdn Bhd as the lead geotechnical of one of the biggest infrastructure projects in the country.

The 51-kilometre Klang Valley Mass Rapid Transit (KVMRT) Sungai Buloh–Kajang (SBK) line, which opened on July 17, 2017, has 31 stations in total—seven of which are underground, located along a stretch of 9.5 kilometres under the city’s central business district. On average, the tunnels run about 30 metres below ground, with the Tun Razak Exchange (TRX) station 40 metres deep (equivalent to about a 13-storey basement carpark).

While many commuters will now benefit from the new connectivity and enjoy the designer stations (check out the Sungai Buloh–Kajang (SBK) MRT Line: Underground Works), what may be less apparent are the challenges involved in venturing so deep in the ground, right in the heart of the city.

Ooi sheds some light on that aspect and shares his experiences with Construction+ Malaysia.
