Transmission and distribution infrastructure

A skilled approach to power transmission line design and planning can maximise asset performance, save time and money, improve safety, and minimise community concerns and impacts.

To help our clients achieve these benefits, we deliver expert designs solution that are safe, innovative, cost-effective, compliant with industry standards and statutory requirements, friendly to communities and the environment, and future-proofed for changing requirements and climate impacts.

Whether you plan to develop, design, maintain, expand, upgrade or rebuild your transmission and distribution infrastructure, we will work closely with you to ensure your assets are developed and operated effectively and safely across their lifecycle.

We can help you complete your project on time and within budget by solving the technical and non-technical challenges of transmission and distribution lines and towers.  Our multi-disciplinary team can supports all phases and aspects of transmission projects from planning and approvals through to defining the route, designing the structure and line, and selecting conductors.  We routinely tackle complex line crossings and deviations, line uprating and line compliance checks.

We can help you develop specifications for turnkey projects, and then support you through the tendering and construction phases to ensure the quality of the build and adherence to specifications and performance requirements.

We can help you identify the true capacity and limits of your transmission and distribution circuits, and propose options for upgrading or uprating the transmission line, conducting lightning analysis to improve reliability, or consider conductor selection, asset evaluation and system studies.

Our specialists in transmission and distribution line engineering, structural engineering, GIS, environment, surveying, law, public consultation and economics can tailor a solution to your specific requirements.
