Definition of information requirements and resulting information models

The appointing party should be knowledgeable about the information required for their assets or projects to support their objectives. They should be able to communicate this information effectively or seek third-party help if they are not competent enough. Appointed parties can add their own information requirements in addition to the appointing party’s requirements.

The appointing parties should state their purposes for requiring information deliverables, including the aspects of the asset that are intended to be managed.

Details on these purposes can be found in section 5.1 of I.S. EN [RM1] ISO 19650-1.

The following are four main types of Information Requirements. Detailed description can be found in sections 5.2 -5.5 of I.S. EN ISO 19650-1

1.     Organizational Information Requirements (OIR)

OIR specifies the information required by an agency for asset management systems and other organisational functions.

Build Digital has published an OIR template as part of their Information Management Plan – Organisational, and this can be downloaded HERE.

For further information, refer to section OIR

2.     Asset Information Requirements (AIR)

AIRs specify the information requirements needed for an asset’s operation and maintenance. They are the information required relating to running and operating a built asset according to a company's plan for managing its assets. OIR is strategic level of information requirements which encapsulates input for AIR.

Build Digital has published an AIR template as part of their Information Management Plan – Organisational, and this can be downloaded HERE.[RM2] 

For further information, refer to section AIR

3.     Project Information Requirements (PIR)

PIR is the information related to managing the design and construction of an asset. It is a further development of OIR but refined to be more project-specific. It is created to meet the needs of appointing parties’ strategic objectives of delivering the asset; it focuses on the specific information that can be provided as part of the delivery stages of a project. The information requested as part of the PIR should inform key decisions at key timeframes during the project’s lifecycle. 

Build Digital has published a PIR template as part of their Information Management Plan – Organisational, and this can be downloaded HERE.

For further information, refer to section PIR

4.     Exchange Information Requirements (EIR)

The Exchange Information Requirements is the information related to a particular appointment. It specifies the information requirements that must be delivered by the supplier (Lead appointed parties, appointed parties) to the appointing party during the delivery phase. It can specify the tools to be used, the level of information need, delivery times, delivery modes, exchange formats, etc. Both AIRs and PIRs are taken into account while developing EIRs.

Build Digital has published an EIR template as part of their Information Management Plan – Appointing Party, and this can be downloaded HERE.

Sample EIR template by Centre of Digital Build Britain are available for use.

S.R. CEN/TR 17654:2021 Guideline for the implementation of Exchange Information Requirements (EIR) and BIM Execution Plans (BIM execution plan) on European level based on I.S. EN ISO 19650-1 and -2.

For further information, refer to section EIR

Information Models

1.     Asset Information Model (AIM)

This information model is handed over to the appointing party at the end of the delivery phase and is used for asset or facility management. It can include a BIM Model, a range of non-graphical data, and documentation.

2.     Project Information Model (PIM)

This is the information model being developed during the project's delivery phase. Once the delivery phase is finished, the final PIM is handed over and is called AIM.

The detailed descriptions of both of these information models can be found in Section 5.6 -5.7 of I.S. EN ISO 19650-1.
