Objective

To complete the replacement of cattle on Delmore Downs Road and Waite River Road, while ensuring the roads stayed safe for users during construction. 

Approach

BluedustNT tackled the project by implementing a comprehensive strategy to replace existing gates with cattle grids on Delmore Downs Road and Waite River Road. They began by arranging all necessary traffic management requirements, documented in a DIPL-approved Traffic Management Plan.

The existing gates were removed and relocated as per arrangements with station owners. To ensure safety, a traffic detour was maintained within the existing disturbed formation, with alignment close to the grid to allow safe bypassing of the works. Clearing and grubbing of small shrubs and bushes were conducted, and the detour was maintained with a watercart for dust suppression and surface compaction.

New double gates were installed in the fence line according to standard drawing CS3313. The pavement and subgrade were lifted to ensure proper drainage and that the grid structure was elevated. Materials for fill and sub-base layers were sourced as sand clay types, and natural gravel was used for the base course from nominated pits. Water for construction was sourced from designated bores, with access negotiated and approved by station owners. A construction camp was established at a gravel pit, with necessary approvals obtained.

The base course was compacted to a minimum thickness of 150mm, transitioning in width to meet the cattle grids approach slab. Concrete work included ready-mixed concrete of 35 MPa grade, with steel fixing and form working. Grid panels, end rails, anchor bolts, strainer posts, gates, and other materials were supplied, delivered, and assembled as per standard drawing CS3313, considering lead times in the construction program. Fencing was reinstated to pastoral standards, with temporary measures to restrict cattle movement during works. All activities complied with AAPA certificates and an approved Environmental Management Plan, with necessary permits obtained before commencement.

Collaboration

BluedustNT worked closely with station owners to arrange the removal and relocation of existing gates and to negotiate access to water sources and construction camp sites.

Community consultations were conducted to address any concerns and to ensure that the project met local needs and standards. Additionally, partnerships with local suppliers were established to source materials such as gravel and concrete. The project also required coordination with regulatory bodies to obtain necessary permits and approvals, and to ensure compliance with environmental and safety standards. This collaborative approach helped to facilitate smooth project execution and fostered positive relationships with the community and stakeholders.

Execution

The execution of the project involved a well-coordinated effort to replace existing gates with cattle grids on Delmore Downs Road and Waite River Road.
