At Your Service

ammjohn Pty. Ltd. specialises in the provision of “Owners Team” (or Owner's Engineer) services. Frequently, ammjohn is called on to perform the roles which some clients describe as a "Group Engineering" function. While our clients’ specific requirements may vary, the fundamental value we bring does not. Whether we supply tailored services (ad hoc) or individuals seconded to the owner or a team of people, we aim to deliver real value to our clients.

Our aim is to ensure 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.
