Hong Kong TMCLK – Innovations and Challenges for Subsea Tunnels
February 8 @ 6:00 pm - 7:00 pm
Antoine Schwob, Project Director at Bouygues Travaux Public, will deliver this lecture on the TMCLK project, a subsea tunnel linking Hong Kong International Airport on Chek Lap Kok Island to the mainland. A flyer for this lecture can be downloaded. The flyer also includes information on how to stream the lecture live on YouTube. FLYER – MinSouth BTS Joint Lecture February 2024
The TMCLK project, which stands for Tuen Mun-Chek Lap Kok Link, was a major undertaking that involved the design and construction of two 4.5 km long subsea tunnels that provide a direct link between the airport and the Tuen Mun area. The TMCLK project also involved 57 cross passages and a 500 m cut and cover section. The project was completed in December 2020 and has significantly reduced the travel time and congestion for airport users and residents.
The project was also a remarkable achievement in terms of engineering and innovation, as it faced many challenges and constraints. The tunnels had to be excavated with Tunnel Boring Machines (TBMs) of 14 m diameter. The TBMs had to operate in difficult geological conditions, such as reclaimed land, mixed ground and hard rock. The cutting tools had to be replaced at a hyperbaric pressure of 5.8 bar, which required special training and equipment for the workers.
The TMCLK project was a joint venture between Bouygues Travaux Publics and Dragages HK Limited, both subsidiaries of Bouygues Construction. The project started in 2013 and lasted for 7 years. The project was recognized as the Major Project of the Year in the over- €500M category by the International Tunnelling and Underground Space Association (ITA) in 2019.
You are welcome to join us for his presentation at the ICE headquarters on Thursday, 8 February 2024 at 18:00. Before the presentation, tea and coffee will be served from 17:30; after the presentation, you can enjoy drinks and food at the newly reopened ICE bar, sponsored by Bouygues-Murphy JV. Don’t miss this opportunity to network with fellow engineers and tunnelling experts!
