Four week project upgrading the 4WD track leading to popular tourist attractions – Jim Jim Falls and Twin Falls.

Intract Australia was contracted by the Director of National Parks to undertake earthworks, pavement and drainage repairs to various Jim Jim Falls, Maguk, 2 Mile and Twin Falls 4WD tracks in the iconic Kakadu National Park in 2013 and 2014 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;
  • Compact subgrade surface;
  • Lay Bidim A34 Geotextile Fabric or equivalent on subgrade surface;
  • Load, haul and compact 150mm trap rock;
  • Finished surface levels are to match adjacent natural surface levels to maintain natural sheet flow as indicated in drawings;
  • Redirect water flow to creek invert;
  • Construct Drainage Diversion Berms – as per drawings at location to be determined on site in conjunction with the Department of Infrastructure and Parks Australia Rangers.

Intract Australia has maintained no less than 60% Indigenous employment for the delivery of its project in Kakadu National Park.
