BIM Uses — Applications of BIM
A BIM Use is a specific body of work the model serves — not a software feature. Choosing the right set of BIM Uses is the first step when drafting an EIR/BEP: it determines the LOIN required, who does what, and which data must be delivered.
22 BIM Uses per Penn State BIM Execution Planning Guide & NATSPEC 2022, organized by 5 project lifecycle stages. Each use has its own page.
22 of 22 uses now have in-depth content: inputs, outputs, step-by-step workflow, diagram, common pitfalls and KPIs. The rest are being added.
Planning(3)
Existing Conditions Modelling In-depth
Create a 3D model of an existing site or building using laser scanning (point cloud) or traditional survey, as a foundation for new design or renovation.
Site Analysis In-depth
Evaluate and select a construction site based on GIS data, wind direction, solar radiation, infrastructure connectivity, geotechnics, and urban planning.
Spatial Programming In-depth
Verify area, function, and zoning against the approved design brief — compare options within the model from pre-design stage.
Design(9)
Design Authoring In-depth
Create architecture, structure, and MEP BIM models — the foundational mandatory use, prerequisite for all other BIM uses. Models contain geometry and properties per LOIN.
Design Review In-depth
Review and approve models visually with the owner, consultants, regulatory authorities, and stakeholders. Comments tracked and managed via BCF format.
Structural Analysis In-depth
Export the structural BIM model to analysis software to calculate forces, verify design codes, optimize sections, and detect problems early.
Energy Analysis In-depth
Simulate building energy performance, thermal loads, and select appropriately sized HVAC systems; compare design options on electricity consumption.
Lighting Analysis In-depth
Calculate natural Daylight Factor, artificial lighting levels, verify QCVN lighting standards, and evaluate lighting electricity consumption.
MEP Engineering Analysis In-depth
Simulate pipe flow rates, calculate electrical loads and cable sizing, verify MEP system pressure and balance before detailed modeling.
Sustainability Analysis In-depth
Compare design options on sustainability criteria (energy, water, materials, indoor comfort), supporting LOTUS, LEED, or Green Mark certification.
Code Validation In-depth
Automated software checks the BIM model against QCVN building codes, fire safety standards, and energy regulations. Basis for BIM-assisted regulatory approval.
3D Coordination & Clash Detection In-depth
Federate discipline models, detect and resolve geometric conflicts (hard/soft clashes) before construction. Track issues in BCF format.
Pre-Construction / Tendering(2)
Cost Management & QTO (5D) In-depth
Automatically extract material quantities from the model, attach unit rates to calculate estimates. Any design change instantly updates quantities and costs.
Phase Planning (4D) In-depth
Link the 3D model with schedule data (WBS) to visually simulate the construction sequence, detect schedule conflicts, and optimize construction methodology.
Construction(5)
Site Utilisation Planning In-depth
Arrange and optimize tower crane positions, storage, site offices, power, and internal traffic routes per construction phase in 3D space.
Construction System Design In-depth
Model formwork, scaffolding, tower cranes, and temporary structures. Use virtual mock-up to verify complex construction sequences before field deployment.
Digital Fabrication In-depth
Extract data directly from the BIM model to drive CNC/plasma machines producing steel, precast, or MEP modules off-site in the factory — reducing field labor.
3D Control & Planning In-depth
Transfer precise coordinates from the BIM model to total stations or GPS machine guidance equipment to locate elements in the field without manual layout.
Construction Documentation In-depth
Produce consistent, auto-updating shop drawings, installation drawings, and schedules directly from the BIM model. Model changes instantly reflect in all drawings.
Operation(3)
Record Modelling (As-Built) In-depth
Update the BIM model to reflect actual as-built conditions, complete metadata (material, manufacturer, warranty). Deliver the AIM (Asset Information Model) for asset management.
Asset Management & FM (6D) In-depth
Use COBie data and model properties in a CMMS/CAFM system to plan maintenance, track assets, and manage space across the asset lifecycle.
Digital Twin In-depth
A digital model continuously updated with real-time IoT sensor data, reflecting the current state of the building and supporting predictive, optimized operations.
