Visualizations for usage agreements from the model

Hold usage-agreement requirements (SIA 260) per space in the model and derive readable visualizations from them.

Starting point

• Area loads, point loads, and vibration requirements are often kept only in tables or coloured plans - hard to align with the space model.
• Changes to room use or load assumptions are easily lost in documentation.
• Client and specialists need a shared, space-based reading of the agreed values.

Goal & benefit

• Keep design target values of the usage agreement directly on interior and exterior spaces in the model.
• Produce coloured plans and visualizations from the model instead of parallel list maintenance.

Process

1. Provide interior and exterior spaces as volumes with use.
2. Capture design area load, design point load, and vibration requirements per space.
3. Derive visualizations and plans from the model and align them with the usage agreement.

Outcome

• Traceable, space-based representation of the agreed usage requirements as a basis for the usage agreement and design basis.

Deliverables

• Architecture model with IfcProject, IfcSite, IfcBuilding, and IfcBuildingStorey
• Interior spaces as IfcSpace (PredefinedType=INTERNAL) and exterior spaces as IfcSpace (PredefinedType=EXTERNAL)
• LongName with use; Name optional
• DesignAreaLoad (design area load) in kN/m²
• DesignPointLoad (design point load) in kN
• VibrationRequirements (vibration requirements) as VC-A … VC-E
