There are several methods for tunnel construction, each suited to specific ground conditions and project requirements, making the selection of the most suitable method essential. Ground investigation is a critical stage, as it provides the information needed to choose the best construction method based on the site's conditions.

This video highlights the risks of tunnelling in poor ground conditions. This underscores the critical need for thorough ground investigations prior to construction stage and probing ahead of tunnel during the construction. The construction method should be adopted based on the geological conditions and risk and proactive ground stabilisation measures should be used where required. Tunnelling is essential for development, but its associated risks must be thoroughly understood, and mitigation mea

Tunnel segments vacuum testing in the factory. As the TBM advances, it excavates the tunnel while simultaneously erecting the tunnel lining. The vacuum erector system in the tunnel utilises suction to lift precast concrete segments into position, precisely fitting them together to form the tunnel's circumference. These segments are typically designed with interlocking mechanisms or gaskets to ensure a tight seal, providing structural integrity and preventing water or soil intrusion into the tunn
