The Employer’s Information Requirements (EIR) form part of the appointment and tender documents on a BIM Project to enable suppliers to produce their initial BIM Execution Plan (BEP). The document is created early as possible (pre-appointment or pre-contract document and before the appointment of design or construction suppliers) either in-house by the Employer or is often the case by their professional advisors (it is essential that the advisor has experience in the creation of EIR documents).

It is important that the EIR grows over time and initally the first iteration might be limited to support a design appointment and secondly to facilitate the procurement of a main contract.

The Employers Information Requirements (EIR's) is a pre-tender document and it sets out the information to be delivered, standards and process that the supplier should adopt during the project delivery process.

The EIR defines what the employer wants to get out of the models at the end. For example, if an employer wants their Facilities Management (FM) team to implement a variable maintenance schedule, this needs to be set out in the EIR so the project team knows they must enter full product specification details into the model.

Information Requirements determined in the Customer Information Model need to be defined as part of the Employer’s Requirements. The EIR defines which models need to be produced at each project stage – together with the required level of definition and their purpose. These models are key deliverables in the information exchanges helping facilitate effective decision making at key stages of the project. Employer’s information requirements usually include:

  • Standard methods and procedures providing clarity on information formats and naming conventions and guidance on how to supply information.
  • Prescribe the standards and processes that suppliers need to adopt as part of their contract or appointment
  • Information-related roles and responsibilities giving a clear definition of information-related roles and what is expected from them.
  • An information delivery plan or information schedule identifying which information deliverables should be delivered, by whom and when.

The content of the EIR covers three main 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 deliverables, timing of information exchanges and definitions of information purposes.
