Six months of preparation.

Naturally, Collett & Sons were left undaunted by the prospect of transporting a 170 tonne Super Grid Transformer across the North West.

The planning for the two-day project actually started six months prior, as much preparation is essential to ensure safe passage of the load. Collett & Sons’ Head of Projects, Liam McLoughlin explains, “In many cases, work on the movements start six months to a year prior to the transportation. Initially the routes are surveyed and if fortunate, there may be a couple of feasible options…the route that will cause the least amount of disruption to the greater public is ultimately chosen.”

Prior to each move, the route is analysed and assured via various methods including computer swept path simulations. While these simulations provide valuable information, they don’t take into account the ‘live’ scenarios and the interaction and unpredictability of other road users.

Therefore, local councils and police forces have to be contacted to ensure additional support can be provided. Typically, traffic signals have to be modified and signs, railings and other street furniture removed plus the assistance of escorts is required, to ensure the convoy has the necessary space to pass through safely.
