Calibre Group has acquired WA mining maintenance services company ARK Maintenance.
The move, through Calibre's subsidiary G&S Engineering, is part of the company's wider expansion in to Western Australia, and of bolt-on acquisitions in general to expose itself to the mining industry.
It acquired ARK for $3.3 million.
Earlier this year Calibre acquired engineering and surveying firm Spiire NZ from Downer EDI.
According to Calibre, it bought Spiire to expand both its exposure to civil and urban infrastructure as well as its presence in New Zealand.
