Constituents of an Information Model

By adhering to these constituents, organizations can ensure that their Information Model serves the project's needs and provides a reliable and robust basis for decision-making throughout the asset's lifecycle. The constituents facilitate the interoperability of data, support collaborative work practices, and ultimately contribute to the delivery of projects with greater efficiency and effectiveness.

They include:

• Graphical Models
  These are the visual components of the Information Model, including 3D models that represent the geometry and spatial relationships of physical elements within the built environment.
• Non-Graphical Data
  This encompasses all the information that cannot be visualized within a graphical model but is associated with its elements, such as technical specifications, performance criteria, and maintenance schedules.
• Documentation
  This refers to the written documents that accompany the graphical and non-graphical data, such as reports, contracts, and manuals. These documents support and explain the information contained within the models and data sets.
• Information Requirements
  Defined by the client, these are the standards and specifications that set out what information is needed, when it is needed, and what quality that information should be. This includes the Exchange Information Requirements (EIR) and Asset Information Requirements (AIR).
• Information Delivery Plan (IDP)
  This is a schedule for when different pieces of information are to be produced, in what format, and by whom. It reflects the stages of the project and ensures timely delivery of information.
• Common Data Environment (CDE)
  This is the digital space where all information is collected, managed, and disseminated. It ensures that all stakeholders have access to current and correct data, providing a single source of truth throughout the project lifecycle.
• Federated Model
  This is the assembled model that brings together the separate models from different disciplines, providing a combined view for analysis and review.
• Level of Information Need
  This defines the detail and precision of the information required at different stages or for different purposes within a project.
• Standards, Protocols, and Procedures
  These are the agreed-upon methods and conventions for creating, managing, and sharing information, ensuring consistency and reliability.
• Information Managers and Roles
  These include the responsibilities and authorities of those involved in the creation, management, and use of the information model.
