Work in caisson
Certain building and civil engineering work is carried out by submerging a type of construction under water, where one carries out the work in, for example, caisson or underground tunnels. The work is carried out under increased air pressure.
Underground tunnels and caisson are examples of specific constructions where one can create a water-free working space in order to carry out foundation work.
This work is risky because water can find its way in, and also because it is carried out under pressure, over-pressurisation. The latter entails risks of decompression sickness in the same way as for divers.
