TL95 Tower Refurbishment Project

Overview

As part of a maintenance & remedial works contract with Transgrid, Genus was responsible for a wide range of tasks related to the maintenance and refurbishment of Line 95.

These tasks included the replacement of tower components such as bolts, nuts, washers, members, insulators, hangers, double link plates, spacers, vibration dampers, and earthwire fittings across multiple towers. Genus  also performed bristle blasting and painting on tower members, along with foundation and stub remediation on selected towers; as well as the replacement of conductor vibration dampers, danger sign plates, anti-climbers, and tower ladders.

Genus also managed site preparation and remediation work, including vegetation clearing, track repairs, and the installation of rock causeways and gates for access. This included dismantling and disposal of all replaced hardware, safe waste disposal, and route clearing for access tracks, including grading and construction of necessary infrastructure.The project also involved the completion of site remediation and the delivery of work as-executed drawings and inspection/test check sheets.
