#36 - Asset Information Model (AIM)

PAS 1192-3 Specification for Information management for the operational phase of construction projects using building information modeling, describes information management procedures for the operational phase of built assets, where assets may be buildings or infrastructure and maybe pre-existing or new assets.

An Asset Information Model (AIM) is a model that compiles the data and information necessary to support asset management, that is, it provides all the data and information related to or required for the operation of an asset.

An AIM can provide graphical and non-graphical data and information as well as documents and metadata. It can relate to a single asset or to a portfolio of assets. An AIM can be created from existing asset information systems, from new information, or from information in a Project Information Model that was created for the construction of a new asset.

An Asset Information Model might include:

• Information describing the original design intent

• 3D models

• Information, or links to information, about ownership, rights and restrictions, surveys, work that has been carried out, operational performance information, condition information, and so on.

For existing assets, some of this information may be incomplete.

The Asset Information Model is managed within a Common Data Environment (CDE). This is the single source of information for the asset. Information within CDE can have a wide variety of status levels, however, there will generally be four main areas of information:

• Work in progress

• Shared

• Published

• Archive

An Information Management Process should be established to maintain the integrity of the AIIM. The AIM is managed by a "Data Manager" with responsibility for accepting information into the shared area of the CDE and authorizing it for the published area.

Changes to the AIM may be triggered by events such as maintenance work, repairs, refurbishments or upgrades, replacement, decommissioning, risk assessments, performance evaluation, changes in regulations, and changes in the party responsible for maintaining or operating the asset. changes in ownership, and so on.
