We provide services across the entire asset lifecycle, from early-stage asset evaluation and project feasibility studies, through design, construction management, fabrication and commissioning, to ongoing support, maintenance and optimisation of mine, rail and infrastructure assets.

Our services are delivered through Calibre Group member companies: Calibre Global, G&S Engineering Services and Calibre Consulting, who together provide a comprehensive capability across the asset life.

We are a leading services provider in the bulk mineral commodity markets in Australia and have a proven track record of delivering large and complex mine and associated logistics projects for our clients, which include the world’s leading iron ore producers.

We have been involved in the study, design and delivery of iron ore projects with a combined production capacity of over 250 million tonnes per annum (Mtpa).
