As BIM continues to expand into the building operation phase, the Guide to Leveraging Building Data in BIM is considered an important reference for project owners and asset stakeholders. The guideline focuses on promoting the utilization of building data through BIM, particularly in facility operation and maintenance stages.
Beyond explaining the benefits and significance of BIM for asset management, the guide also introduces various use cases and real-world examples, helping organizations better understand how BIM can be applied in actual operational workflows. It serves as a valuable reference for owners aiming to optimize management efficiency, enhance asset value, and improve long-term building data utilization.
Building data can be categorized into four main groups. By integrating these data types, various building-related information can be visualized and utilized more effectively.
This is BIM data primarily created by design and construction teams.
In addition to building geometry, BIM data also contains information such as: Area, Height, Building functions andTechnical specifications. When linked with unique identifiers such as property IDs, BIM data can connect with the other three data groups.
This data is generated during building management and operation.
It includes: Periodic inspection records, Repair & maintenance history, Revenue data and Tenant information
This refers to monitoring and observation data collected in real time during building operations.
It includes: People flow data, Space utilization status, System operation status, IoT and sensor monitoring data
This is evaluation data created based on standards or regulations established by authorities and professional organizations.
It includes: Real estate transaction prices, Building performance data, Asset evaluation indicators, Benchmark and performance data
Applying building data to operation and management not only brings social benefits such as improving disaster resilience and supporting urban development, but also creates economic value through cost optimization and improved operational efficiency.
However, since BIM also requires costs for data creation and maintenance, it is important to balance benefits and costs when selecting suitable use cases.
BIM Data × Stored Data
(Inspection results, deterioration/failure data, equipment operating hours, etc.)
This enables more efficient maintenance, inspection, and cleaning operations. Optimizing repair timing and priorities can significantly reduce maintenance costs.
BIM Data × Index Data
(EPD – Environmental Product Declaration data)
Using CO₂ data from materials and products simplifies whole-life carbon calculations throughout the building lifecycle.
BIM Data × Stored Data × Real-Time Data
By managing HVAC systems more efficiently, it is possible to create a comfortable indoor environment while minimizing energy consumption and operational costs.
BIM Data × Stored Data
(Tenant contract information, building revenue, operational costs, etc.)
This enables more efficient lease management. Lease administration and tenant report generation can also be automated.
BIM Data × Stored Data × Real-Time Data
This allows visualization of congestion levels in meeting rooms, restrooms, and public spaces, improving convenience and user experience.
BIM Data × Stored Data × Real-Time Data
This helps improve office utilization rates, optimize office layouts, and enhance workforce allocation efficiency.
BIM data for building operation and maintenance is created and utilized through the following workflow.
To restructure BIM data from the design and construction stages into a format suitable for operation and maintenance, data classification rules must first be established. This includes space classification for asset management, classifications for inspection and maintenance, and the development of data structures for FM/BM workflows.
Based on the intended use cases, the necessary data should be identified. In operation and maintenance, space-related information and equipment/material information are considered especially important.
Based on steps 1 and 2, an EIR (Exchange Information Requirements) document is created for operation and maintenance BIM development. The EIR defines requirements such as BIM objectives and implementation schedules, BIM data LOD (Level of Development), and contractual roles and responsibilities.

Based on the established EIR, the owner assigns designers or contractors to develop BIM data for operation and maintenance purposes.
The BIM model used for operation and maintenance is generally based on the design BIM LOD, with additional information finalized during construction, such as equipment installation information, equipment part numbers, and service life data.
For existing buildings, operation and maintenance BIM data is created from existing design documents and site condition surveys.
After completion, BIM data is integrated with property management systems, operation management tools, and ERP/FM platforms. This integration allows BIM data to go beyond visualization and be directly utilized in actual operation, maintenance, and asset management workflows.

BIM today is no longer just a 3D model, but a data platform that connects the entire building lifecycle — from design and construction to operation and asset management. By integrating operational data and management systems, BIM helps organizations optimize costs, improve operational efficiency, and maximize building performance.
