Overview
IEC SRD 63273-2:2024 - Smart city use case collection and analysis: City information modelling (Part 2: Use case analysis) provides a structured, standards-focused analysis of real-world use cases for city information modelling (CIM). Part 2 develops a curated database of user stories and use cases, performs integrative analyses, and scopes requirements to guide IEC and other standards development organizations (SDOs) on applying CIM for urban planning, management and operations.
Key topics and technical requirements
- Use case collection & user stories: Compilation of domain-specific use cases across city functions (new town planning, 3D property visualization, construction approval, project management, real-estate registration, city brain/operations, heritage preservation, transport planning, traffic control, water management, census, underground pipeline management, emergency response).
- Stakeholder & actor analysis: Identification of human stakeholders and non-human actors to clarify roles, responsibilities and data flows.
- Needs statements & requirements scoping: Extraction of needs statements from use cases and translation into requirements for CIM standards (data models, interoperability, workflows).
- Integrative analysis methods: Cross-cutting analyses (word-frequency, integrated stakeholder-requirement mapping) to prioritize standards needs and recommend standardization actions.
- Deliverables for SDOs: Recommendations to IEC and other SDOs on scope and content of CIM standards to support urban planning and management.
Practical applications
IEC SRD 63273-2:2024 is practical for organizations implementing or specifying digital city solutions:
- Urban planners & municipal authorities: to define standardized CIM requirements for planning, permitting and asset management.
- Standards developers & SDOs: to inform normative CIM scope and interoperability priorities.
- BIM/GIS vendors and integrators: to align product data models and APIs with identified use cases and stakeholder needs.
- Infrastructure operators & utilities: to support underground pipeline tracking, water management and lifecycle asset workflows.
- Emergency services & transport agencies: to standardize data exchange for traffic management, evacuation planning and incident response.
- Heritage managers & real-estate registries: to adopt 3D visualization and registration workflows.
Who should use this standard
- City CIOs and digital twin program leads
- Standards committees and working groups
- GIS/BIM solution architects and system integrators
- Planners, utility managers, emergency planners, and digital city consultants
Related standards (context)
This SRD is intended to feed recommendations to IEC and other SDOs and complements existing BIM, GIS and digital twin standardization efforts by providing empirically grounded CIM use-case requirements.
