Blackbutt Range Restoration

The D’Aguilar Highway through the Blackbutt Range was temporarily closed in early 2011 as a result of major landslip damage along a 2.5km stretch following torrential rain and cyclonic conditions. Reconstruction of the highway was undertaken by Burchills Engineering Solutions. The project was jointly funded by the Commonwealth and State Governments as part of their emergency response works across Queensland.

Burchills undertook a 12 month environmental management and auditing contract for the second half of the project. Works included preparation and ongoing revisions of the Construction Environmental Management Plan and Erosion and Sediment Control Plan as well as weekly environmental audits and monthly environmental reporting to the Principal.

Project Innovation & Client Outcomes:

There were many environmental challenges specific to this project including ongoing land instability issues, remote location, steep terrain, extreme weather events, poisonous plants, endangered flora, predation of hydromulch seed by birds, dispersive soils and a sensitive receiving environment.

These challenges led to some innovative, adaptive responses from Burchills Environmental Scientists including the use of seed predation repellent mechanisms and the installation of a remote sensor rain gauge. Burchills also negotiated permission from SEQ Water to access recycled water for irrigation from a pipeline that ran through the project area.
