Asset information requirements AIR
Asset Information Requirements (AIR) are part of the Building Information Modelling (BIM) process, defining the graphical and non-graphical data, information and documentation needed for the lifetime operation and management of a built asset.
ISO 19650 defines AIR as 'information requirements in relation to the operation of an asset'; an information requirement is defined as 'specification for what, when, how and for whom information is to be produced'.
The efficient delivery and operation of a built asset relies partly on the operators’ ability to make sure the right people have access to the right information, in the right format and at the right time in order to make well-informed decisions and to effectively operate the asset.
In the BIM process, these information needs are called asset information requirements: the information required to operate and maintain a built asset throughout its lifecycle. The information will be about the real-world built asset (i.e. what was actually built, not what was planned).
The asset information requirements will be formally and explicitly defined in a document called the Asset Information Requirements (AIR). This document will define the requirements for the provision and management of information about a built asset in line with the organisation’s wider asset management plan, as defined in the Organisational Information Requirements (OIR).
Asset information requirements, once defined, will help enable the creation of an Asset Information Model (AIM). The data and information collated in response to the AIR comprises the AIM, which will therefore contain all the information required by the asset management plan in the required format for the lifetime operation and maintenance of the asset.
The AIR should cover the entire asset lifecycle. As such, the AIR informs the development of the Exchange Information Requirements (EIR (ISO 19650)), or Employer’s Information Requirements (EIR (BS/PAS 1192)), for a capital project.
“…AIR shall be specified as part of a contract or as an instruction to in-house teams and may use data and information from the AIM relating to the asset management activities being carried out. The AIR shall also specify data and information to be captured and fed into the AIM. Where the activities relate to major works covered by PAS 1192-2, then the AIR will inform the EIR.”
This paragraph instructs that AIR:
- Should be specific to an asset;
- Should be included as part of a contract or delivered as an instruction to in-house teams;
- Will inform the information requirements defined in the EIR, where the asset activities relate to major works covered by PAS 1192-2;
- Will specify data and information that will be captured and added to the AIM; and
- May include information about the asset management activities and strategies being carried out using the AIM.
The AIR should define what information will be required to operate and maintain the asset throughout its lifecycle. These information requirements can be extremely broad and comprehensive. They will inform the contents of both the AIM and the EIR document.
However, the final document should be very precise and exact. PAS 1192-3 continues on to say that the AIR “should then be developed into a digital plan of deliverables.” This means that the AIR should not only define what information is required, but also how that information should be delivered in order to be used in the operation and maintenance of the asset.
- Managerial: Defines the information standards and production methods and procedures to be used by the delivery team.
- Commercial: Defines the information standards and production methods and procedures to be used by the delivery team.
- Technical: Details the information specifications to meet the organisational information requirements relevant to the asset.
|Type of Information||Examples of Information|
In defining the AIR, the asset owner and/or operator needs to specify the information-sharing protocols and the information and systems to be deployed. On a capital project, these protocols are prescribed in the EIR. During the operation and maintenance of assets, these protocols should be documented in the Asset Management Plans.

 AIR and Organisational Information Requirements (OIR)
An asset management strategy should be defined at an organisational level, rather than on an asset-by-asset basis. Asset Information Requirements (AIR) should therefore be developed from organisational information requirements. As with asset information requirements, organisational information requirements are defined in a document entitled Organisational Information Requirements (OIR).
According to ISO 19650, the OIR provides the input to the AIR (i.e. is the only source of input to the AIR).
 AIR and Asset Information Model (AIM)
The information added to an AIM can come from different sources: existing asset information systems, new information (e.g. if upgrades are made to the existing asset), or information in a Project Information Model (PIM) that was created for the construction of a new asset or the modification of an existing asset.
In the case of a new asset, the AIR will have been used to develop the Exchange/Employer’s Information Requirements (EIR). These will have been incorporated into the tender documentation for the project and used to define the delivery of the asset information.
 AIR and Exchange/Employer’s Information Requirements (EIR)
The Exchange Information Requirements (EIR (ISO 19650)), or Employer’s Information Requirements (EIR (BS/PAS 1192)), is the document used to communicate the organisational and asset information requirements (OIR & AIR) to the contractor(s) and subcontractor(s) employed on a project.
Therefore, asset information requirements identified by the OIR and defined in the AIR will be used to create the EIR.
According to ISO 19650, the AIR provides an input to the EIR (i.e. it is not the only input).
