aBCD - Quality solutions, efficiently delivered, without compromise.
aBCD is a unique enterprise consisting of Brolton Group, an Indigenous-owned mechanical and electrical engineering contractor; Calibre, a multidisciplinary infrastructure, technology and engineering consultant; and Diona, a utilities specialist delivering essential community infrastructure.
Our name features the first letters of each of the three businesses; B for Brolton Group, C for Calibre and D for Diona. Brought together we form aBCD Enterprise.
aBCD is committed to providing end to end design and infrastructure solutions. With a national footprint and decades of experience, clients can be confident in our community-first and quality approach. Safety is an integral aspect of our business and our teams are committed to deliver value for the life of the asset.
While our Indigenous-owned credentials are desirable, clients choose aBCD due to our unique combination of services, capabilities and scale. In addition, our project delivery comes with a high level of self-performance across all aspects of the life cycle. We care and deliver the work. Where we partners with other firms - credentials are critical. Equally important is the ability to partner with firms to support local communities and jobs in the regions where the work is being delivered.
As a privately Australian owned business, we are committed to giving back to the Australian community. We care about our project legacy and the communities we work with. Combined aBCD employs over 1500 staff and indirectly we support thousands more.
