Understanding EIR Terminology in PAS 1192 and ISO 19650

In the world of Building Information Modeling (BIM), the terminology around the Employer’s Information Requirements (EIR) is critical, especially when comparing standards like PAS 1192 and ISO 19650. Both frameworks play an essential role in guiding BIM projects, but the evolution from PAS 1192 to ISO 19650 has introduced some new terminology and structural changes. In this newsletter, we’ll break down these differences and explain how they impact your BIM processes.

What Is an EIR?

The Employer’s Information Requirements (EIR) is a key document used in BIM projects. It outlines the information that the employer needs to operate and maintain the asset after it has been built. This includes the specification of models, data formats, and other key deliverables.

EIRs provide clear guidance to project teams on the information that must be generated, structured, and delivered during the design, construction, and operational phases. It acts as a roadmap for the Common Data Environment (CDE), ensuring the right data is delivered at the right time.

EIR in PAS 1192

The PAS 1192 standards (especially PAS 1192-2) introduced the concept of the EIR as a formal document used during the procurement stage of a BIM project. PAS 1192 emphasized creating a robust EIR that would:

• Define project objectives and deliverables
• Outline the information exchange process
• Set out the required Level of Detail (LOD) and Level of Information (LOI)
• Specify software and file formats for interoperability

These elements were crucial for aligning all project participants on the information flow and quality, ensuring that the delivered asset met the employer’s operational requirements.

EIR in ISO 19650

With the introduction of ISO 19650, the EIR concept was further refined, and some terminology shifted. While ISO 19650 builds on PAS 1192’s foundations, it introduces the Project Information Requirements (PIR) and the Asset Information Requirements (AIR) as two key documents under the umbrella of the EIR.

• Project Information Requirements (PIR): Defines the information needed for effective project delivery, ensuring the project runs smoothly and meets the outlined objectives.
• Asset Information Requirements (AIR): Focuses on the information needed for the ongoing operation and maintenance of the asset after project completion.

Additionally, ISO 19650 emphasizes the importance of the Information Delivery Plan (IDP) and the Information Management Process, which are designed to manage and track how data is delivered across different stages of a project.

The framework in ISO 19650 shifts from focusing solely on the project phase to providing a more holistic view that includes the asset’s full lifecycle.

Key Changes from PAS 1192 to ISO 19650

While both PAS 1192 and ISO 19650 seek to manage information effectively in BIM projects, there are some key changes in ISO 19650 that are worth noting:

1. Terminology Changes:
2. Lifecycle Focus: ISO 19650 introduces a more structured approach to managing the asset lifecycle, ensuring that both project and operational information requirements are met from the start.
3. Global Standardization: ISO 19650 is designed as a global standard, while PAS 1192 was more regionally focused. ISO’s broader adoption makes it more suitable for projects with multinational stakeholders.

Practical Impact on Your BIM Projects

For BIM professionals, understanding the EIR framework under ISO 19650 is essential for smooth project execution and compliance. The shift in terminology and focus means that project teams must be aware of both the project delivery phase and the operational phase of an asset.

At Abacus AEC BIM Services, we specialize in helping organizations align their projects with these evolving standards. Our team ensures that your EIR, PIR, and AIR are clearly defined, effectively communicated, and meticulously delivered. Whether your project is aligned with PAS 1192 or transitioning to the ISO 19650 framework, we offer tailored BIM solutions to meet your specific requirements.

Conclusion

The evolution from PAS 1192 to ISO 19650 represents more than just a shift in terminology—it’s a fundamental change in how information is managed across the lifecycle of a project. For BIM professionals, staying up-to-date on these standards is crucial for success. By fully understanding the new EIR-related terms and their practical implications, you can ensure that your projects are well-structured, compliant, and efficient.
