ACOR and Defence
ACOR has been servicing projects in the Defence sector for over 25 years. Our success is built on our industry background and scalability. We have delivered over 670 Defence projects ranging from $15,000 to $1.5bn. To find out more about our projects, please contact our team.
Of our 400 staff, over 150 hold security clearance. ACOR has over 300 staff members who have delivered Defence projects in the last five years, and over 130 are currently delivering an active Estate Works Program (EWP) or Capital Facilities Infrastructure (CFI) project.

To ensure that ACOR provides a “best for project” approach, we have developed a Program Management Office (PMO) organisational structure supported by a Centre of Excellence (COE). This adds value by:
- The PMO is broken into geographic regions servicing all of Australia.
- We have design management teams based across our ten offices, who coordinate each Defence project and act as the client’s single point of contact.
- Each design manager has access to our COE support, founded on a repeatable and efficient service that strives to continually improve and incorporate lessons learnt. Examples of COE support include the use of repeatable design, specifications, and reporting tools, BIM and digital support, price benchmarking, and HOTO support and implementation.
ACOR acknowledges and values the abilities and experience of Australian veterans. In addition to directly employing veterans, we are proud to have signed the Veterans’ Employment Commitment and are a proud Gold Pledge sponsor for Soldier On, which is dedicated to recognising veterans’ skills and experience and enhancing their employment opportunities.
ACOR was also a finalist in the Defence Connect Australian Defence Industry Awards for Consultancy of the Year in 2022 and Defence Innovator of the Year – Company category in 2023 in partnership with Augility/JLL Australia.
