Carnarvon Fascine Development

Requirements 

The Fascine Revetment Wall was built in stages between the mid 50’s through to the mid 70’s to provide protection to the town from river flow from the South Arm of the Gascoyne River and wave action from its exposure to the sea.

 The Department for Planning and Infrastructure (DPI) was awarded a contract for the construction of a 3.5 km long and 30 m wide channel between Teggs Channel and the Tramway Bridge, and the dredging of a boating basin within the Fascine.

These projects involved the removal of approximately 210,000 m³ and 190,000 m³ of material respectively.

Additional works included the dredging of access channels to Carnarvon Yacht Club and Carnarvon Beach Holiday Resort.

Initial work involved assisting DPI in terminating a contract on the basis of non performance and subsequently re-letting the contract.

The project involved the dredging of predominately sand and silt to form reclamation areas suitable for development.

Minor works included design and installation of navigational aids along a 3.0 km channel leading from offshore to the proposed development.
