Construction contractor John Holland Group has blasted its way into WA's booming oil and gas sector with a $160 million contract to build Apache Energy's Devil Creek gas plant in the Pilbara, snaring work originally to be undertaken by Clough.

Apache initially awarded Perth group Clough a $260 million contract to design and build the Devil Creek onshore facilities in April last year, followed two months later by a $200 million contract to build all associated offshore facilties at the Reindeer gasfield which will supply the plant.
