INTRODUCTION
China ranks first in the world both in the number of tunnels and the speed of development. In 1979, China had only 374 road tunnels, with a total length of only 52 kilometers. By the end of 2001, that number had reached 1,782, in a total length of more than 700 kilometers, making China the country with the most tunnel and underground projects, the most complicated engineering and the fastest tunnel development in the world. By 2010, more than 155 kilometers of road tunnels will have been built in China. The 18.4-kilometer-long Zhongnan Mountain tunnel, which will pass through the Qinling Mountain range, will be the second longest in the world and the first in Asia. Many other mountain tunnels each with a length of 4-8 kilometers will also be constructed. Currently in 2018, China has 1.72 million kilometers of roads, including 200,000 kilometers of expressways. China ranks the world's second in expressway mileage, and the length will reach 230,000 kilometers by the end of 2018. Construction of road tunnels in Malaysia gained worldwide recognition as for the first time the SMART project, a dual purposes road tunnel was constructed for solving the drainage problem and traffic congestion in the business district of Kuala Lumpur. The Joint Symposium was mooted to exchange experiences in tunnel construction industry in both Malaysia and China through the Institution of Engineers, Malaysia (IEM) and China Civil Engineering Society (CCES) respectively. Amongst the many tunnel projects to be presented in the symposium is the Hong Kong–Zhuhai–Macau Bridge (HKZMB) which is a Bridge–tunnel system, which consists of a series of three cable-stayed bridges and one undersea tunnel, as well as 3 artificial islands, spanning the Lingdingyang channel, that connects Hong Kong with Macau and Zhuhai, three major cities on the Pearl River Delta in the South China Seas. Construction cost: More than 100 billion yuan. Opening is scheduled for 1st July 2018. Construction ended on 14th November 2017 with total length of 49,968 metres.
The two days symposium will be held on 18-19 September 2018 in P J Hilton Hotel in Petaling Jaya in Selangor which is 10 km away from the City of Kuala Lumpur. The Joint symposium is the first of its kind to be held in the Institution of Engineers, Malaysia (IEM). There will be eight speakers from CCES and eight speakers from IEM. The Joint symposium is ITA endorsed event as part of the publicity of WTC2020 and 46th General Assembly to be held at the KLCC in Kuala Lumpur.
