He AND GO (Employer's information requirement, by its acronym in English) or Employer information requirements It is one of the first documents that must be written when working with the BIM methodology.
It's about a document of great importance in the BIM process which is defined in the PAS 1192-2 standard as a “Document configuration prior to the tender of the BIM execution plan. The information to be delivered to the property is defined, and the standards and work processes to be adopted by the designer as part of the project delivery process. As such, it is also a key starting point for management and contractors when engaging in BIM projects.
The EIR, when working in BIM, should be one of the first documents issued. It is essential to write the BIM Execution Plan (BEP) since it defines the client's needs for each stage of the asset construction process. It is designed to be included in bidding documents for both the project design team and the builder. The content of the EIR has to be incorporated into other subsequent bidding documents.
What should the EIR include?
The writing of an EIR has to detail the project requirements for each phase of the project. It is a standardized document in many cases, which simplifies and facilitates communication between the agents involved in drafting the BIM project. All content of the EIR will require review and validation prior to publication to ensure that there are no project-specific issues that have not been taken into account.
The EIRs are an essential element in the implementation of a BIM project, since they establish the models and information requirements What the client needs from the project and that the designer must follow, as well as his management method.
These requirements are divided into three areas:
- Technical area: It contains aspects such as what software the project will be developed in, the medium and format in which the participants will share the information and any other aspect related to the project information such as training, advice, etc. It is important that the Development Level of the model is included in this area.
- Management area: It includes the role played by each project collaborator and their responsibilities, the way in which collaborative work will be developed, security, schedules and delivery strategies.
- Commercial Area: The results and goals that are desired to be achieved with the analysis of the previously stated data are shown. They refer to the synchronization of data, the presentation of results and an evaluation of the competition.
The EIR is the pre-bid document that contains the standards and processes to be adopted by the supplier as part of the project delivery process. As dictated by the PAS 1192-2 standard, in each proposal to qualify for the bidding concession, all the information requested by the property in the bidding process must be provided (hence the importance of the EIR), a outline of the BEP that is offered, which must contain at least:
- A Project Implementation Plan.
- Some collaboration objectives.
- An information modeling.
- Model delivery strategy.
