BIM Employer’s Information Requirements (EIR)

The Employer’s Information Requirements (EIR) form part of the appointment and tender documents on a BIM Project.

Information Requirements need to be defined as part of the Employer’s Requirements.  The EIR define which models need to be produced at each project stage – together with the required level of detail and definition.  These models are key deliverables in the ‘data drops’ – contributing to effective decision making at key stages of the project.

The content of the EIR covers three areas:

  • Technical – details of software platforms, definitions of levels of detail etc
  • Management – details of management processes to be adopted in connection with BIM on a project
  • Commercial – details of BIM Model deliverables, timing of data drops and definitions of information purposes


The EIR is presented as a model document complete with guidance models.  The content can be incorporated into other tender documentation. The content of the model EIR is advisory.  As the BIM protocol requires details of Building Information Models and Information Management processes, the EIR provides an effective platform to communicate these requirements as part of an appointment process.
