Exchange Information Requirements (EIR)

What is an Exchange Information Requirements (EIR)?

The Exchange Information Requirements (also called EIR) is an essential document in the BIM process defined in PAS1192- 2 as a “pre-tender document setting out the information to be delivered, and the standards and processes to be adopted by the supplier as part of the project delivery process”. As such it is a key starting point for clients when engaging in BIM projects.

The Exchange Information Requirements contains some clear instructions about how a construction project should be executed. According to BSI, the EIR is a document that "determines the appointing party’s information requirements in relation to an appointment (contract). It identifies what the appointing party expects to be delivered during both the delivery and handover. It includes responsibility, timescales, format, and level of information need of the project information. It also includes any other project-specific requirements, such as procedures to be adopted, the plan of work to be used, any format restrictions, and 12 should consider (amongst other things) the Project’s information Standard, OIR and AIR respectively". Therefore the EIR provides both parties, the construction team, and its client, with enough information to answer a request for proposals/tenders or how the constructor plans to meet project deadlines. The Exchange information requirements also serves in a regulatory role as it ensures that information is provided and made available to all parties involved where and when requested.

There are different information requirements that aid in generating and informing an EIR. The Organization Information Requirements (OIR) helps in defining what information is required to achieve an organization’s strategic objectives about business operation, asset management, etc. It describes the needs of an owner organization to manage its building portfolio and related services. Project Information Requirements (PIR) defines what information the appointing party of a project needs from the delivery team. It describes the owner’s requirements for the management of a specific facility. It can be related to the details of facility spaces (the rooms which are functional within the building), the services (the operational and maintenance activities that occur in these spaces), and the equipment properties: type, location, maintenance requirements, replacement period and costs). Asset Information Requirements (AIR) Specifies the information to be delivered by the project team at the project handover phase, mainly for operations and facility management of the project.

Here is a short summary of the different Information Requirements needed in a construction project:

  • OIR (Organizational Information Requirement): the OIR is a document that defines the data and information necessary for an organization to satisfy its requirements and meet its objectives.
  • AIR (Asset Information Requirements): The AIR is a document gathering all the required assets, management, and maintenance procedures.
  • PIR (Project Information Requirement): The PIR gives a clear understanding of what asset information should be delivered for each project.
  • EIR (Exchange Information Requirement): the EIR is a document that defines how to transfer the information, in what format, what level of information, and establishing an agreement among stakeholders on how and with what features they need to exchange their digital information.

    What does an Exchange Information Requirements (EIR) contain?

    A typical EIR will be divided into three areas covering Technical, Management, and Commercial aspects.

    In the Technical part, we will find detailed information about :

    • The software platforms that the client wants to use in the project. It can be, for example, the Common Data Environment (CDE).
    • Data Exchange Formats
    • Level of detail
    • Training requirements

    In the management part, we will find information concerning:

    • Standards
    • Stakeholder's roles and responsibilities
    • Security
    • Coordination and clash detection process
    • Collaboration process
    • Compliance plan
    • System performance constraints
    • Model review meetings
    • Health & safety, and construction design management
    • Planning work and data segregation (model management, naming conventions, etc.)
    • Delivery strategy for asset information

    In the commercial section will be contained information about:

    • Timing of the data drops ( which corresponds to the data extracted from the evolving building information model and submitted to the client at key milestones.)
    • Client strategic purpose
    • Defined BIM project deliverables
    • BIM-specific competence assessment
