Karijini National Park Road and Car Park Upgrades

The scope of works includes, but not limited to;

• Gravel Production from within Karijini National Park
• Earthworks and construction of drainage including rock armouring of road side drains.
• Innovative methods to maximise reuse of existing road surface materials and reduce environmental impact e.g. surface mining methodology or similar alternatives are required;
• Weano Road and Banjima Drive will involve cement stabilisation of floodways;
• Large portions of the road construction are proposed to be carried out with a surface miner or similar alternative;
• Construction of the gravel basecourse pavement layer;
• Construction of a two-coat bitumen emulsion seal;
• Installation of painted pavement marking;
• Supply and installation of steel wheel stops and steel bollards;
• Supply and installation of road signs;
• Construction of the cement stabilised gravel footpaths and standard compacted gravel footpaths;
• Rehabilitation of lands impacted by the works, i.e. turn arounds and gravel pits etc

Modern technologies and methodologies are sought to create reusable road base materials out of existing rocky road surfaces, thereby reducing the need to source road base materials from the gravel pits located within Karijini. Karijini is a high profile National Park and dust and vibration mitigation is an important issue within the park. Contractors should address this issue in their tender submission.
