SMEC Holdings Limited traces its origins back to 1949 to the landmark Snowy Mountains Hydroelectric Scheme, one of the civil engineering wonders of the modern world, before formally incorporating as the Snowy Mountains Engineering Corporation (SMEC) in 1970. In 2016, SMEC joined Singapore-based Surbana Jurong (SJ) Group, creating a global multidisciplinary powerhouse spanning urban development, infrastructure, and management consulting. With a network of over 5,400 specialists operating across more than 40 countries, SMEC provides engineering design, advisory, and project delivery services across complex transit, rail, and heavy civil projects.

In the rail and transit sector, SMEC delivers end-to-end capabilities spanning route alignment, geotechnical investigations, deep rail tunnels, trackwork engineering, bridge and viaduct structures, traction power electrification, signalling, and communications. The company is deeply integrated into high-profile national freight and passenger transit networks, including Australia’s 1,700-kilometre Inland Rail freight corridor, the Sydney Metro network (including Sydney Metro West and Northwest packages), the Melbourne Metro Tunnel, and Cross River Rail in Brisbane.

Internationally, SMEC has delivered major rail programs throughout South and Southeast Asia, the Pacific, the Middle East, and Africa. Key international references include extensive detailed design, independent engineering verification, and construction supervision for the Padma Bridge Rail Link Project and Dhaka Metro (MRT Lines 1 and 5) in Bangladesh, the Klang Valley MRT (KVMRT Putrajaya Line) in Malaysia, and dedicated freight and regional passenger rail modernisations across Africa and Central Asia.
