Task - Access Track Maintenance Program
Value - $1.8m
Date - 2009/12
Background
TransGrid is a state owned corporation that owns, operates and manages the NSW high voltage electricity transmission network, a system comprising 82 substations and switchyards and over 12,400 kilometres of transmission lines up to 500kV. A vast system of access tracks services this infrastructure, much of which traverses rugged terrain and requiring regular maintenance work. SCS won a 3 year contract to reconstruct and repair access tracks in Southern, Central and Metropolitan NSW.
Objectives
To maintain TransGrids system of access tracks and trails to enable their service vehicles to access their towers and radio repeater sites in order to undertake routine maintenance and repair and to allow access to their easements for vegetation management.
Works Undertaken
Since awarding of the contract in November 2009, numerous jobs have already been undertaken or signed up totalling > $500,000. One of the first to be undertaken and completed was a series of badly degraded tracks servicing the Number 11 line near Waterfall. This rugged country is typical of the sandstone escarpment country encountered in the Sydney-Illawarra area. The work involved rock hammering of rock ledges in the track, ripping, regrading and shaping the road and importing clay to cap the road and construct rollovers. Mitre and table drains plus some bed level creek crossings were constructed.
Outcomes
The work undertaken by SCS plant will ensure access to the States electricity grid is maintained and that the work is done in accordance with the highest environmental and safety standards.
