During the implementation of BIM (Building Information Modeling), EIR (Element Information Requirements) and BEP (BIM Execution Plan) are two important concepts. So, what are EIR and BEP, and why do they play such an important role in BIM?
In Part 1, let’s explore EIR with BIMCAD VietNam.
EIR is a document that outlines the Employer’s Information Requirements. It is provided to contractors before the contract is signed. Specifically, this document defines the requirements such as the level of detail of the BIM model, how the BIM process will be managed, and the roles and responsibilities defined within the contract.
EIR (Element Information Requirements) is a crucial document in the BIM implementation process, providing detailed information about the attributes and characteristics of each element within the model. To develop an effective EIR, the following factors should be carefully considered:
Clearly defining objectives is extremely important when developing an EIR. BIM can be applied to address various issues, from building consensus among stakeholders and evaluating design performance to assessing the project’s impact on the surrounding environment.
When creating an EIR, considering the project’s impact on the surrounding environment is also important. BIM models can be used to simulate factors such as lighting, wind, and noise. In this case, the level of detail (LOD) of the model will focus on environmental-related elements, such as building heights, the location of trees, and the orientation of windows.
In addition to the factors mentioned above, timing is also an important part of developing an EIR. For example, it is necessary to clearly determine whether building consensus with facility managers during the design stage will be carried out only once before completing the concept design, or whether it will occur twice, including during the design policy development stage.
Detailed attributes related to materials, equipment, and model parameters are essential data sources for creating accurate and comprehensive evaluation reports. This information helps ensure accuracy, reduce errors during assessment and decision-making, and enhance the transparency and reliability of EIR-related reports.
Clearly defining the requirements that BIM software must meet is a crucial step in developing an EIR. This ensures that the BIM model can fully satisfy the upcoming project’s requirements. Software capabilities, features, and interoperability must align with the scale and complexity of the project.
The EIR document must also define the required project deliverables. The format and expectations from stakeholders regarding the final outputs are important elements within the EIR. For example, if a company requires a detailed 3D building model delivered in IFC format along with the native file (e.g., Revit), these requirements must be clearly specified in the EIR to avoid misunderstandings during project implementation.

Developing an effective EIR (Element Information Requirements) is a crucial foundation for the successful implementation of BIM in construction projects. An EIR not only provides detailed information about the elements within the model but also guides the workflow of the entire project team.
