About the event

This type of tunnelling solution is usually favoured for harbour and sub-sea environments due to its shallow depth below the seabed, that allows shorter tunnel lengths and better connections to the road network at both ends of the subsea section.

In addition, the shape of an immersed tunnel is flexible to fit different projects. This form of tunnelling is where our speaker has spent most of his career as an engineer. He often gets asked how to connect watertight boxes in a chain together, some nearly as tall as a three-story building, in waters as deep as 50 metres.

This is one of the reasons why CK Tsang enjoys designing immersed tunnels; the seemingly impossible nature of the task, but the immense benefit it brings to cities by connecting its people between their destinations. Its status really becomes an invisible landmark for a city.
