Standards we work with
| Standard / format | Type | What it is used for |
|---|---|---|
| VDI 3805 | Guideline · DE | Product data exchange in building services. Manufacturers provide geometry and technical data so that planning software can read them directly. |
| ISO 16757 | International standard | Data structures for electronic product catalogues in building services — the international continuation of the VDI 3805 concepts. |
| IFC | ISO 16739 · buildingSMART | Open, vendor-neutral exchange format for BIM models between different software products. |
| Revit | Autodesk · RFA | Native families with parameters, MEP connectors and type catalogues that behave like Revit’s own components. |
| STEP | ISO 10303 | Neutral CAD format for exact 3D geometry — the starting point for simplified BIM geometry and conversions. |
| ETIM | Classification | Open classification model for technical products with language-independent features, widely used in electrical, HVAC and plumbing. |
| ECLASS | Classification · ISO/IEC | Cross-industry standard for the classification and unambiguous description of products and services. |
| CSV · XML · JSON | Data formats | Machine-readable formats for connecting PIM and ERP systems and manufacturer portals. |
| DPP | EU · ESPR | Digital Product Passport under the EU Ecodesign Regulation: product information across the entire lifecycle. |
02
One digital data model. Many BIM ecosystems.
Every stage has defined inputs, outputs and validation rules.
| Step | What happens | Typical formats |
|---|---|---|
| 1 · Manufacturer data | We collect everything that already exists about the product and clarify what is missing for BIM use: data sheets, catalogues, price lists, ERP/PIM exports, design CAD. | PDF, XLSX, STEP |
| 2 · Product data preparation | Cleansing, structuring and classification of product information. | XLSX, CSV, ETIM, ECLASS |
| 3 · 3D geometry | Simplified, performant BIM geometry derived from design data, with installation and maintenance space. | STEP, GLB, RFA |
| 4 · BIM parameters | Parameters, connectors and type catalogues mapped to the target standards. | RFA, IFC, VDI 3805 |
| 5 · QA / validation | Rule-based checks plus four-eyes engineering review. | Validation report |
| 6 · BIM content | Delivery of the validated BIM objects and data sets. | RFA, IFC, VDI 3805 |
| 7 · Digital platforms | Publication in manufacturer portals, BIM libraries and digital product platforms. | Portal, CSV, XML, JSON |
03
Levels of information
| Term | Meaning |
|---|---|
| LOD | Level of Development — maturity of a model element |
| LOG | Level of Geometry — geometric detail |
| LOI | Level of Information — alphanumeric detail (parameters, properties) |
04
Operation
- Digital Twin — a digital representation of a building or asset that is kept up to date with operational information.
- CAFM — computer-aided facility management systems that use asset and maintenance data.
