The United Kingdom transport infrastructure is one of the busiest in the World and all projections point towards the pressure increasing on the system as we move into the first half of the 21st Century. Unsurprisingly then, Government and private spending is aimed at increasing the efficiency of the current systems with minimal disruption to its current use. Utility diversion work is common to all projects and the challenge for designers is to find new routes for existing utilities in roads and pavements that are far more crowded than they were ever intended to be. Accurate utility drawings are the start point for this work and Adien’s non-intrusive methods are ideal for both accurately detecting and mapping utilities whilst minimising road congestion and disruption to the commuter.
