Intract Australia was contracted by the Director of National Parks to undertake earthworks, pavement and drainage repairs to various Jim Jim Falls, Maguk, Two Mile and Twin Falls four wheel drive tracks in the iconic Kakadu National Park to improve their accessibility. A concrete boat ramp was also constructed at Twin Falls.
Elements of the scope included excavating (box out) varying widths as shown on drawings and to a maximum depth of 200mm, compacting subgrade surfaces, laying Bidim A34 Geotextile Fabric or equivalent on subgrade surface, and loading, hauling and compacting 150mm trap rock. Finished surface levels were to match adjacent natural surface levels to maintain natural sheet flow as indicated in drawings. Other works included redirecting water flow to creek inverts and constructing drainage diversion berms.
Intract Australia maintained no less than 60% Indigenous employment for the delivery of this project.
