StructBOQ

StructBOQ — IFC Validation System

StructBOQ is not a BOQ generator. It is a quality gate between your model and downstream engineering decisions. It reads your IFC file directly — Revit, ArchiCAD, Tekla, Allplan — and audits every element for classification errors, unit inconsistencies, volume anomalies, and quantity source failures before generating a validated BOQ. Supports IFC2x3, IFC4, IFC4x3.

What to watch for

How the pipeline distinguishes IfcQuantityVolume from geometric fallback — and when each is used
Where misclassified elements are caught before quantities are committed to the BOQ
The final Excel structure: element list, audit flags, and summary sheet in one file

Setup required Zero Upload, receive report

StructBOQ investigates IFC semantic reliability, quantity traceability, and model assurance across open BIM workflows.

What Gets Validated

Element classification — footings, slabs, columns, beams, proxies
Quantity source — BaseQuantities, Pset, or geometric fallback per element
Unit consistency — cm², mm², m² conversion traps across all software
Reinforcement extraction — bar geometry, designation lookup, ratio fallback
Semantic anomalies — GrossVolume corruption, void relationships, composite assemblies

Validation Accuracy Cross-checked against raw IFC data in Bonsai / BlenderBIM across three software platforms.
