Automated
permit checker

From BIM model to permit compliance in minutes.

Upload an IFC model and automatically validate it against municipal regulations using BIM, GIS and knowledge graph technology. Instantly identify compliance issues before a permit review even starts.

Automatic Permit Checker

Automate permit reviews with BIM, GIS and semantic data

The Automatic Permit Checker combines BIM models, municipal GIS data and digital regulations into one automated workflow.

Instead of manually interpreting regulations and checking drawings, the platform evaluates your design against applicable rules and immediately highlights where compliance issues occur.

Every result is fully traceable, visualized in 3D and linked to the underlying regulation.

What You Can Build With Wistor

Highlights

The Automatic Permit Checker demonstrates how semantic technologies transform permit reviews from a manual process into an automated workflow.

By combining BIM, GIS and regulations within a knowledge graph, every compliance check becomes transparent, reproducible and scalable.

Municipalities, engineering firms and developers receive instant insight into compliance issues, significantly reducing review time while improving consistency and quality.

Import IFC model

The application imports IFC models and extracts building elements, geometry and object properties into a semantic knowledge graph while preserving relationships between all objects.
Link municipal GIS datasets

Building models are automatically georeferenced and enriched with municipal GIS datasets, including parcels, roads, hydrants, zoning boundaries and environmental data.
Semantic rule mapping

Regulations are translated into machine-readable rules and linked to the corresponding BIM and GIS objects through the ontology, enabling fully automated validation.
Execute spatial analyses

Geometric, topological and network analyses calculate distances, visibility, accessibility, intersections and spatial relationships directly across BIM and GIS data.
Apply machine-readable regulations

Compliance rules are executed automatically for every relevant object in the model, producing consistent, repeatable validation results without manual interpretation
Visualize explainable compliance results

Every result remains traceable to the originating BIM object, GIS dataset and regulatory rule, allowing users to understand exactly why a building passes or fails a specific check.

Usecase

How it works

The problem Building permit reviews rely on manually comparing BIM models with regulations, GIS data and planning documents. This process is time-consuming, error-prone and often requires multiple specialists working across disconnected systems.

The solution The Automatic Permit Checker combines BIM, GIS and machine-readable regulations in a semantic knowledge graph. After uploading an IFC model, the application automatically enriches it with location-specific data and executes compliance checks across multiple regulatory domains, providing transparent and explainable results.

The results

Permit reviews are completed in minutes instead of weeks. Compliance issues are identified automatically, every result is fully traceable to its source, and organizations benefit from faster, more consistent and scalable permit assessments with significantly less manual effort.
