Our Way of Business

We value our reputation as a consistent provider of integrated project management services, maintaining high standards for people, safety and quality.

Our flexible approach to project delivery reflects our commitment to ensuring clients receive the most cost effective solution as part of the project delivery method, while maintaining our statutory obligations at all times.

We can guarantee our ability to deliver due to our team’s experience and commitment.

At Your Service

ammjohn specialises in the provision of “Owners Team” (or Owner’s Engineering) services. Frequently, ammjohn is called on to perform the roles that some clients describe as a “Group Engineering” function, a function that in the past would have been completed by an “in-house” team of engineers and designers.

While our client’s specific requirements may vary, the fundamental value we bring does not. We can supply tailored services, including individual consultants to work with the owner on a secondment, or a team of multi-disciplined people. In all cases, we aim to deliver real value to our clients.

Our service model ensures that clients and owners maintain control of their projects by assisting them with all aspects of project management. In doing so we address key questions as to whether or not the client’s appointed designers and constructors are delivering fair value in a timely and efficient manner. We are equipped to provide advice on all aspects and all problems that an owner is likely to encounter, before, during and after construction and commissioning.


ammjohn offers its clients customised solutions or expertise in project engineering and management.
