Understanding the Level of Information Need is crucial in the context of Building Information Modeling (BIM) and the ISO 19650 appointment workflow. It helps determine the depth and detail of data required at various project stages, ensuring efficient collaboration and decision-making. In this article, we will explore how this concept integrates into ISO 19650 processes to optimize project outcomes.
Aligning Information Needs with ISO 19650 Appointment Workflow
The ISO 19650 series provides a structured approach to managing information throughout the lifecycle of a built asset. A key component of this structure is the clear definition of Information Requirements (IRs) and Information Delivery Specifications (IDS). The Level of Information Need determines how much detail must be included in each data exchange, depending on the project phase, stakeholder role, and intended use.
In the context of the ISO 19650 workflow, the appointment phase involves setting up responsibilities, establishing information requirements, and defining the project’s BIM execution plan. During this stage, understanding the precise level of information needed ensures that data collection, sharing, and management are both effective and efficient, avoiding over- or under-specification that can lead to delays and increased costs.
Practical Application in Project Phases
As projects progress through various phases—ranging from strategic briefings to detailed design, construction, and operation—the Level of Information Need evolves accordingly:
- Strategic and Concept Design: Focus on broad, high-level information such as spatial requirements, functional descriptions, and initial scope. Minimal detail is sufficient to make early decisions.
- Design Development: Increase in data detail is necessary to refine specifications, interfaces, and coordination among disciplines. Information is progressively defined and elaborate.
- Construction and Handover: Precise, detailed models are required for fabrication, installation, and eventual asset management. The level of detail must meet the specific needs of contractors and facility managers.
This phased approach ensures the right information is available at the right time, enhancing collaboration and reducing rework. The ISO 19650 standard emphasizes the importance of defining these levels early in the appointment process, which helps in establishing clear responsibilities and deliverables aligned with the project’s lifecycle.
Furthermore, integrating the Level of Information Need into the appointment workflow supports the use of structured data definitions such as the COBie format for asset data and enables more reliable data handovers, facilitating effective facility management post-construction.
Conclusion
In summary, the Level of Information Need is a fundamental concept in BIM and ISO 19650 workflows, guiding the appropriate level of detail required at each project stage. Properly aligning information needs during the appointment phase promotes better collaboration, reduces risks, and enhances overall project delivery. Embracing this approach ensures a streamlined process from design to operation, yielding long-term benefits for all stakeholders.
