Another essential use of the underground space in urban environments is the distribution of electrical and communication cables.
With the huge development of communication technologies that we are witnessing nowadays, an increasing number of cables for internet communication is being placed underground in major cities.
Rapid changes in communication technology mean flexibility is an essential factor. It is very important to conceive distribution channels which make the update of cables and other elements easy and quick.
This is one of the reasons why the installation of electrical and communication cables along underground utility tunnels is so advantageous, as there is no need of excavating and obstructing the public ways every time the network is to be renewed or enlarged.
