Our Expertise

From holistic and sustainable townships to innovative public infrastructure solutions, our expertise grows along with the needs of the industry.

Explore one of our three competency pillars below.

Challenging geotechnical engineering

The biggest challenge in our underground construction works are the geological formations beneath Kuala Lumpur.   The tunnelling works primarily face three types of key geological formations, namely Kenny Hill, Karstic Limestone and Granite, with most of the tunnel alignment situated in Grade V karstic limestone.

The underground portion of the MRT Putrajaya Line traverses very complex geological conditions. There are many mixed-face conditions, as well as interfaces of different geological conditions and faults. There are quite a lot of quartz intrusions as well, which makes it a lot more challenging.

The land condition for the MRT Kajang Line also proved to be challenging as the tunnel had to cross the two main landforms of sand and sedimentary rock formation at Kenny Hills and limestone formations in Kuala Lumpur.

With such unpredictable and complex geological conditions at play, controlling ground loss and pressure fluctuations in the midst of tunnelling works is vital to avoid sinkholes, reduce settlement and limit the impact on existing structures. To tackle these complex conditions, we rely on our Variable Density (VD) Tunnel Boring Machine (TBM) which is able to operate in multiple modes and the enhanced Autonomous Tunnel Boring Machine (A-TBM)

Asia's First Tunnelling Training Academy

Gamuda has an excellent track record of creating jobs and training during the project delivery.

Launched in 2011, with an investment of RM10 million, the  Gamuda's Tunnelling Training Academy (TTA) is the first  academy that develops niche talent for the highly specialised  field of tunnel construction. It is the world's first learning  institution specialising in Tunnel Boring Machine (TBM)  technology. The TTA was set up to address the shortage of a  competent, local workforce for the tunnelling works.  The academy has trained over a thousand tunnel engineers  and skilled superintendents. 

The establishment of this academy is in line with the Government's aspirations to transform Malaysia into a high-income nation as well as being part of MMC Gamuda's  training initiatives to upgrade knowledge, skills, and  performance of workers in the local construction industry for  future projects. 

We have planned to further enhance our TTA courses by  collaborating with industry experts Bosch Rexroth and Schneider Electric Malaysia to meet local and international  tunnelling construction requirements.
