EIR and BEP are the core documents for successfully tendering and implementing BIM in a project.

Before analyzing ordering processes, some basic terms must be clarified:18

• Appointing party - as the receiver of information.

• Appointed party - as the provider of information.

• Appointment – as agreed instruction for the provision of information.

From “Guideline for the implementation of BIM Execution Plans (BEP) and Exchange Information Requirements (EIR) on European level based on EN ISO 19650 1 and -2”

All terms and concepts are in accordance with EN ISO 19650-1 and -2

A lead-appointed party should be assigned for each delivery team.

Usually, the appointment of information delivery is a three-step process, see the figure below:

Invitation to tender

The appointing party establishes exchange information requirements (EIR) for each lead appointed party’s appointment, considering, where appropriate, the organizational information requirements (OIR), asset information requirements (AIR) and project information requirements (PIR).

An EIR is issued to each prospective lead appointed party being invited to tender for the relevant appointment.

Tender response

The prospective lead appointed parties respond to the EIR with a BIM execution plan (pre-appointment).


When the lead-appointed party is selected, the lead-appointed party confirms the BIM execution plan and provides a defined set of information about the execution of the deliverables within its perimeter of responsibility.

EIR (Exchange Information Requirements)

The appointing party establishes the exchange information requirements to list all applicable information requirements. The exchange information requirements are provided to the potential appointed parties.

Where information requirements can state why, what, when, how produced, and for whom the information is needed (organization (OIR), asset (AIR) or project (PIR) information requirements). Informing the appointed party why the information

is needed will allow them to innovate in the method of information production and delivery for the appointing party’s business needs. Further information requirements should be a brief description of the purpose, the desired outcome and/ or delivery of the appointing party’s business need and information need.

BEP (BIM Execution Plan)

The BIM Execution Plan documents are updated by the Lead Appointed Party in agreement with appointing party and appointed parties to confirm the specifics that shall be used for the specific project. An information delivery strategy should reflect the lead appointed party’s approach to meeting the information requirements as specified in the EIR. Also, the delivery team structure (overview of appointed parties) and/or the breakdown of the delivery team into task teams are part of the delivery strategy and therefore should be specified here. The delivery team’s information delivery strategy should also contain a set of objectives/goals for the collaborative production of information.
