Founded in 1974, International Tunnelling and Underground Space Association (ITA) is the leading international organization which aims to encourage the use of the subsurface for the benefit of public, environment and sustainable development and to promote advances in planning, design, construction, maintenance and safety of tunnels and underground space, by knowledge sharing and application of technology. Presently, ITA gathers 78 Member Nations and 266 corporate or individual Affiliate Members.

ITA holds, at once, its General Assembly and the World Tunnel Congres (WTC) in a different Member Nation, each year.


The Institution of Engineers, Malaysia (IEM) was established in 1959 and its primary function is to promote and advance the science and profession of engineering in any or all of its disciplines and to facilitate the exchange of information and ideas related to engineering.

Membership of the Institution is currently about 40,000 and the growth rate is about 10% per annum making it one of the largest professional organisation in Malaysia. In order to support the needs of members, the IEM has 8 Standing Committees to attend to the different administrative functions of the Institution. To support the multidisciplinary needs of engineering practice, there are more than 17 Technical Divisions ranging from civil, mechanical, electrical, mining, agricultural engineering, and many others as well as 4 Special Interest Groups to look after and to organise activities for the different disciplines. There is also a Young Engineer Section and Women Engineers Section that caters exclusively to the younger members and women engineers respectively.

The Tunnelling and Underground Space Technical Division (TUSTD) of IEM was endorsed as the 50th Member Nation of the International Tunnelling Association (ITA) at the General Assembly held in Durban, 13th -18th May 2000. TUSTD was formed during the end of 1999 with the initial objective to assist in the planning of the ITA Executive Council Meeting held in Kuala Lumpur, 24th – 28th February 2000. Since then, TUSTD was officially inaugurated in 2000 with the objective to undertake activities related to the promotion and advancement of the science and engineering aspects of tunnelling and underground space technologies both locally and internationally.

The IEM has event organising experience since 1970s. It has organised many successful international conferences, workshops, seminars and other training courses.
