What is the Asset Information Model (AIM)?

The Asset Information Model or AIM is a term used to describe the collated set of information gathered from all sources that supports the ongoing management of an asset.

The AIM serves as a single source of validated and approved information that relates to a built asset and is used during the operational phase of a building. It is a term that may relate to a single asset, a system of combined assets, or an organisation’s entire portfolio of assets.

Where does the production of the AIM fit in a BIM workflow?
The PAS 1192 suite of documents provide defined processes, such as collaboration using shared models developed to common standards, as well as activities including model co-ordination, interface management, and information quality management.

The Project Information Model (PIM) is developed during the design and construction phase of a project in response to requirements set out in Employer’s Information Requirements (EIR). The PIM will typically consist of a federated building information model, a range of non-graphical data and documentation. Starting off as a design intent model, level of detail will increase and, eventually, become a virtual construction model containing all objects need to be manufactured, constructed or installed.

At project completion required information from the PIM is transferred to the AIM in accordance with the processes and data set out in the EIR. This process is set out in detail in PAS 1192:3.

What information is contained in the AIM?
The AIM comprises models, data, documents and other records related to or required for the operational phase of an asset.

It might include information outlining the original design intent, details of ownership, survey work undertaken, operational performance details as well as 3D models developed on the project.

Who uses the information in the AIM and what for?
The AIM is used by clients, end users and facility managers as a building enters the Operation and In Use phases of the project lifecycle.

Building owner/occupiers will use the data and information contained in the AIM to answer the Organisational Information Requirements (OIR) to support business operations.

Asset management suppliers will use the data contained in the AIM to manage their activities effectively.

The AIM should deliver a fully-populated asset data set that can, if required, be used by computer-aided facility management systems (CAFM). This software allows facility managers to plan, execute and monitor activities required to deliver proactive and reactive maintenance, explore space configuration and manage moves. Vendors like Bentley (Asset Wise), Business Collaborator (BC), Ecodomus (BIM Platform) and others produce software products that allow an asset information model to be established.
