TRACK FORMATION RECONDITIONING PACKAGE A
Abergeldie was engaged as head contractor by The Australian Rail Track Corporation (ARTC) to carry out a series of rail track formation reconditioning projects at several locations in the Hunter Valley. This series formed as one package of works within ARTC’s year-long program of maintenance and upgrade works across the Hunter Valley network.
Abergeldie provided Early Contractor Involvement (ECI) prior to the contract award, project management, track formation reconditioning, surface and sub-surface drainage works, signalling adjustments, rail safeworking, acid sulphate soil spoil management and traffic management.
Formation reconditioning works were carried out over distances of 180m to 250m, at two locations near Branxton, Minimbah, the up and down coal lines at Hexham, High Street, Pages River, Roseglen, Rosemount Road level crossing and Mangoola level crossing.
SCOPE OF WORKS
- rail removal and replacement;
- track formation excavation and reconditioning;
- resurfacing support;
- geotechnical testing;
- signalling adjustments and
- spoil management.
COMPLEXITY AND INNOVATION
Some preparatory works outside the Danger Zone were carried out mid-week adjacent to live rail traffic, with part of the package being carried out during strictly scheduled weekend rail possession conditions. To take maximum advantage of the limited available time during possessions, works during these periods were programmed on an hour by hour basis and closely supervised to ensure on-time hand-back. Works were completed on budget and ahead of schedule.
At several locations, spoil management was complicated by large volumes of acid sulphate contaminated material. Detailed plans and procedures were prepared and activated for testing and neutralising, aeration and blending to enable the contaminated material to be handled and disposed of safely.
Contractor Performance Reports from the client for each section of the works reflected a consistently high level of client satisfaction with all aspects of project planning and delivery. Abergeldie worked collaboratively with ARTC under their ONETEAM principles to look outside the project area, identify the root cause and complete improvements at every site, improve access, drainage and remove adjacent defects that impacted ARTC’s customers.
