About Us

AIE is a specialist engineering consultancy servicing the needs of clients throughout Australia and New Zealand. Our expertise spans the marine, buildings & infrastructure, power & energy, mining & metals, roads and rail sectors.

Specialising in concrete technology, structural remediation, corrosion and cathodic protection, AIE has a strong understanding of how best to manage our client’s assets. From completion of an initial inspection of your asset/s we can then develop a detailed asset management plan, allowing you as the client to get a full understanding of your current risk profile. Depending on your requirements this can then lead into a cost effective maintenance strategy to ensure the assets are returned to a structurally sound condition.


Utilising AIE’s Project Development Process (APDP) we offer a personalised project management service for small to large projects, covering all stages of project development from feasibility to Front End Engineering & Design (FEED), from detailed design to construction completion, and from commissioning to operations.

AIE lead the way in Australian & New Zealand engineering practice in marine, concrete, steel, corrosion and cathodic protection technologies. We have a strong safety culture and understand our client’s needs when it comes to the management of HES throughout the engineering and construction phases of a project.
