CopperString Power Line Project - LiDAR and Mapping

The AU$1.5 billion Copperstring Project is a proposed 1041-kilometre long, high-voltage electricity line between Woodstock near Townsville and Mount Isa. It is considered one of Queensland’s most important infrastructure projects.

CopperString Pty Ltd is a partnership between CuString Pty Ltd and Leighton Contractors Limited. RPS was engaged by Leighton Contractors to map the broad corridor in which the final alignment would lie. Once the feasibility for such a large project is given the green light, there is an urgent need to obtain accurate data so the final alignment can be determined and dependent activities, such as land holder negotiation, tower location and line design can be commenced without costly delay.

RPS collected High Definition LiDAR and simultaneous digital aerial photography within a tightly constrained time frame of August 2010 to November 2010. The line designers also required detailed feature mapping including three dimensional powerlines. RPS carried out this mapping using the LiDAR and photography, and provided Leightons with 3 dimensional strings in CAD format.

This large project with challenging technical specifications was delivered on time and on budget.
