Decmil was appointed to complete restoration works and upgrade the D’Aguilar Highway Blackbutt range crossing as a result of nine land slips which developed in January 2011.

The works were undertaken to current road design, safety, geotechnical and environmental standards. Tree clearing was required and revegetation was carried out progressively in consultation with the Department of Environment and Resource Management.

The reconstruction work included long-term geotechnical stabilisation works, drainage and pavement works, with provision made to accommodate heavy vehicle movements. The project was delivered under the Natural Disaster Relief and Recovery Arrangements (NDRRA).

The main works under the PICR contract included:

  • Road realignment, stabilisation and sealing/asphalt of approximately 3km in length of D’Aguilar Hwy
  • 350,000m3 of earthworks including significant slip repairs which involved removing and replacing existing material all under single lane traffic
  • 6,000m soil nails
  • 5,000m3 of shotcrete
  • 2,000m3 of rock fall netting
  • 500m of kerb and channel
  • 1,500m concrete roadside drains
  • 10,000 tonnes of asphalt
  • 1,600m of guard rail
  • 10 hectares of landscaping including seeding, weeding and planting

Delivering solutions.

We are committed to outstanding project management and delivery regardless of the scale or the intricacy of the work.
