Abigroup joint venture wins $65 million Rio Tinto contract

21 February 2011

Abigroup, in joint venture with indigenous contractor Geraldton Line Haul (GLH), has been awarded a $65 million contract by Rio Tinto for works on its Cape Lambert Port B Project, near Karratha in Western Australia.

The contract involves a 4.3kp quarry development, earthworks for the wharf abutment and tug harbour and the partial removal of the existing tug harbour breakwater.

Mark Davidovic, Abigroup’s Western Australia Engineering Manager, said, “We’re delighted to have secured this major contract with Rio Tinto which represents an important milestone for Abigroup, being our first joint venture project undertaken with an indigenous contractor. 

“We have a strong relationship with GLH and look forward to working together in delivering an outstanding result. The project demonstrates Abigroup’s commitment to the sustainable development of indigenous businesses and personnel in the regions in which we operate.”

The quarry work includes the pioneering of the upper levels of the quarry by drill and blast and recovery of material for use in a crushing and screening operation.

Operating quarry benches and daily drill and blast activities will be established to produce raw feed material and armour and the blasted material will be sorted, loaded and hauled to either stockpiles or the crushing and screening operation.

The construction of the wharf abutment and breakwater involves:

  • clearing, grubbing, topsoil stripping and surface soil stripping;
  • excavate and remove existing materials;
  • load, haul and place core material and rock armour to the abutment and breakwaters; and
  •  extension of existing road crossing over the power station cooling water outlet.

The construction of the tug boat harbour extension includes the removal, temporary storage and reuse of tug boat harbour armour rock and core material and loading, hauling and placing the core material and rock armour.
