Information Delivery Specification (IDS) checker – validate IFC files against defined requirements

IDS turns project information requirements into clear, machine-readable rules. Our IDS checker validates your IFC files against those rules in the browser, so you can prove compliance before delivery and avoid last-minute surprises.

What is IDS?

IDS (information delivery specification) is a structured way to describe what information a model must contain. Instead of vague text requirements, IDS uses explicit rules for properties, classifications, element types and more. That makes checking faster, repeatable and auditable.

Why validate against IDS?

Meet employer’s information requirements with evidence
Standardise QA across projects and suppliers
Reduce rework by catching issues before client review
Create a repeatable, documented compliance process

How the IDS checker works

Upload your IFC file.
Select or upload an IDS file (client or project standard).
Run the check to validate the model against every rule.

The report shows passed and failed requirements and flags any detected issues in the IFC or IDS file structures.

AI fix: step-by-step remediation

When a requirement fails, AI fix detects the authoring software and version used to create the IFC, then suggests step-by-step instructions to correct the data. Examples include which parameter to edit in Revit, which property set to update in Archicad, or where to apply a classification in Tekla. This removes guesswork and speeds up re-exports.

Group checks and share progress with snapshots

Tag and group checks by project or package to track progress across versions. Share read-only snapshots with stakeholders so everyone can see pass rates, failed rules and what changed between model updates.

What IDS can test

Required properties and expected values
Type vs instance parameters (e.g. type mark, fire rating)
Classification codes and formats (e.g. Uniclass)
Presence of attributes like Name or PredefinedType

Supported tools and schemas

Revit, Archicad, Tekla Structures, Vectorworks, Bentley OpenBuildings
IFC 2x3, IFC 4, IFC 4.3

If your software exports valid IFC, we can validate it against IDS.
