Operations and Maintenance Manuals (O&MM) for Defence Facilities and Infrastructure

These Instructions for Operations & Maintenance Manuals for Defence Facilities (O&MM Instructions) are provided to Defence and contracted personnel for development and regular update of the Operations & Maintenance Manuals (O&MM).

The O&MM Instructions provide contractors and project stakeholders with sufficient guidance and clarity to consistently and economically provide Defence with concise, simple and useful O&MMs that can be stored and accessed on Defence Estate Information Systems.

The O&MM Instructions also seek to ensure contractors provide Defence with WHS information necessary for Defence to discharge its duties as a person conducting a business or undertaking (PCBU) to workers and other persons under the Work Health and Safety Act 2011 (Cth) and its associated regulations (collectively WHS Legislation).

WHS Information for the purposes of these instructions includes manufacturer, designer, importer supplier, installer, commissioner or constructor literature and information required to be provided by the WHS Legislation

To assist with the development of new O&MMs, a generic template titled “Estate OMM Template” is provided and this must be used when providing Defence with Building and Base Infrastructure System O&MMs. The Estate OMM Template is saved within a compressed zip file “.zip” that also includes a folder-set covering the generic folder structure for Building O&MMs and Base Infrastructure System O&MMs and a generic O&MM template (Word document). A copy of the Estate OMM Template can be obtained from the link below.
