IFC Audit · Automation · BIM Innovation

Your models contain data. BIMCheck turns it into decisions and reliable tools.

I help owners, BIM managers, engineering offices and operators check IFC files, formalise IDS requirements, structure Swiss classifications and turn repetitive verification into reliable tools.

Two pillars, one standard

Data audit and tool development: two complementary skills.

An assignment can remain a focused audit or go as far as formalising a reusable check. In both cases, scope and deliverables are made explicit before work starts.

01BIM Quality

BIM data audit & quality

When the model must become verifiable.

IFC checks, IDS requirements, Swiss eCCC-Bât / CFC classifications and digital handover preparation. The goal: turn diffuse discrepancies into clear, prioritised decisions that can be passed to teams.

  • Entities, Psets, units and classifications checked
  • Issues prioritised with BCF trace or compliance table
  • Deliverables oriented toward acceptance, operations and maintenance
Expected output: audit report, prioritisation and correction path.

02BIM Tools

Tools, automation & custom development

When a check must become repeatable.

Revit plugins, Python scripts and business applications turn repetitive checks into reusable, documented and maintainable tools. Tools start from a use case, identified inputs and a verifiable result.

  • Automation of repetitive and sensitive BIM tasks
  • Business applications for auditing, tracking and delivering data
  • Short documentation and usage transfer to the team
Expected output: usable tool, short documentation and usage handover.

Pillar 2 — Development & Automation

BIM tools that remove everyday friction

A good BIM tool does not start with code: it starts with a check or export that causes a problem. Winter turns repetitive tasks into focused, documented tools adapted to the agreed scope.

01

Revit business-rule checking plugin

Check parameters, populate Psets, verify classifications or export clean data directly from the production environment.

Demonstrations

Examples of checks and deliverables

Demonstrations show the method and expected outputs. Client results are only published with real data and explicit permission.

01

Example 01 — IFC audit before handover

Demonstration — fictional data

Illustrative IFC model check covering entity typing, property presence, units, spatial structure and classifications.

Output: summary, issue table and correction recommendations.

02

Example 02 — Automated BIM check

Test scenario — no client savings claimed

Test scenario showing how a repetitive check can be turned into a reusable script or tool.

Output: structured report, execution log and short documentation.

03

Example 03 — Digital handover preparation

Fictional example — no client data

Example of asset-data structuring for handover: identifiers, location, FM properties, classifications and tabular exports.

Output: control table and list of missing data.

Problems solved

The problem is not the 3D. It is the data behind it.

An IFC file can look good and still be unusable. Checks cover entities, properties, units, classifications and deliverables.

Incorrectly typed IFC objects

Before audit

IfcBuildingElementProxy, imprecise categories, fragile quantities.

After audit

Typed entities, expected properties and isolated issues in the report.

Incomplete Psets

Before audit

FireRating, Uw, LoadBearing or net areas missing or inconsistent.

After audit

IDS check, missing values listed and corrections ready to communicate.

Unclear eCCC-Bât / CFC codes

Before audit

Classification stored as free text or absent from objects.

After audit

IfcClassificationReference checked and Swiss correspondences documented.

Repetitive manual checks

Before audit

Exports, verification and consolidation repeated manually at every milestone.

After audit

A documented rule, script or tool to replay the check on the right scope.

Services — audit, handover, tools

One contact connecting requirements, data and automation.

IFC audits and BIM tools are handled in the same dialogue, with a factual approach, a defined scope and documented delivery.

One point of contact connecting BIM requirements, IFC data and automation.

I work on situations where a model looks correct but cannot demonstrate a requirement, produce a reliable export or prepare a structured handover. The starting point is the real context: intended use, available files, project phase and responsibilities.

Checks may cover IFC, IDS, ISO 19650, eCCC-Bât and CFC according to the supplied requirements. They distinguish what can be verified in the export, what belongs to a project convention and what requires a decision from the owner or project parties.

When a verification or data transformation becomes recurrent, I can formalise it as a Revit plugin, Python script or business application. The tool is scoped with its inputs, outputs, documentation and operating limits.

Engagement framework

What guides every assignment

A clear scope, documented checks and explicit limits.

Independent, data-centred audit

Every discrepancy is measured, prioritised and documented — entities, properties, classifications and deliverables — never merely skimmed.

Checks based on identified references

IFC, IDS, ISO 19650 and eCCC-Bât / CFC references frame checks defined against project requirements.

Traceable deliverables

Report, BCF, compliance table or tool documentation: the output is defined according to the validated scope.

One point of contact

BIM requirements, IFC data and automation are handled in one exchange, with explicit scope and limits.

Method

Five steps, from context to validated deliverable

A short progression to scope, verify, document and deliver without promising beyond the agreed perimeter.

01

Define the intended use

Define the need, scope, requirements and limits of the assignment.

02

Review files and requirements

Read IFC exports, project documents, IDS and available conventions.

03

Check or prototype

Run the checks or build a first tool prototype on the validated scope.

04

Prioritise and document

Classify discrepancies or formalise the use, inputs and expected results.

05

Deliver and validate

Share the deliverable, its limits and next actions with the relevant people.

Tool-assisted checks automate repetitive verification while keeping an actionable trace of discrepancies.

FAQ

Frequently asked questions before an IFC audit

Short answers to questions that commonly arise before starting a BIM quality check.

What is an IFC audit?

An IFC audit checks the entities, properties, units, classifications and deliverables of a BIM model to identify discrepancies before coordination, handover or operations. The expected result is a prioritised issue list that owners can understand and project teams can act on.

How much does a BIM quality check cost?

The Express format starts at CHF 890 for a focused first review. A full project audit is generally between CHF 2,500 and CHF 6,500 depending on the number of models, IDS requirements, classification level and expected deliverables.

What is the difference between eCCC-Bât and CFC?

eCCC-Bât classifies costs by construction element, while CFC organises them by type of work. In an IFC model, the challenge is to carry these codes in a structured, stable and verifiable way to avoid manual rework at the end of the project.

How long does an IFC Express Audit take?

The schedule is defined after reviewing the file, project context and check scope. The proposal states the planned deadline and deliverables before work starts.

Why check IDS compliance?

An IDS specification makes requirements machine-readable. It can verify that objects contain the expected properties in the right place and format. This reduces late interpretation and makes corrections easier to prioritise.
