The creation of a tram network for Edinburgh will take the form of two main construction phases – utilities diversion and network construction.

Agreements have been reached with utilities companies (gas, water, electricity, etc) to put in place a single, co-ordinated contract to move all the underground cables and pipes which lie underneath the tram tracks in preparation for the construction of the tram tracks themselves.

This means that all utilities equipment and facilities currently located underneath or very close to the tram network will be moved at the same time, minimising disruption and allowing access to pipes and cables in the future without disrupting tram operations.

The £40 million contract for this work was awarded to Carillion in October 2006.
