Asset Information Requiements Guidance. The AIR is a document which forms part of the ISO 19650 process, put simply it should articulate the asset data the organisation or owner would like to be delivered on project completion. In many cases it is likely that asset/facilities management processes are already in place within your organisation, however they may not have been structured in a manner which enables them to be specified as a project deliverable. The AIR specifies the information required to successfully operate and maintain an asset, typically focusing on specific components of an asset. This guidance document helps to ask specific questions of your existing asset management processes in order to develop a suitable AIR for your project.
