An EIR (Employers Information Requirements) sets out the information that the end user requires from the 3D model. Having an agreed EIR is therefore important when commissioning a survey for asset capture and facility management.
While a BEP (BIM Execution Plan) is the project plan developed in direct response to the client’s EIR and documents how the project will be organised and executed; and how and when the information will be created and by whom.
Because the 3D model is so fundamental to the success of the project delivery under BIM the BEP should consider the survey model, who will use it, how they intend to use it and what LoD and LoI is required to ensure that the survey model is fit for their purpose.
