Regional BIM Governance & Cross-Border Delivery

The German-speaking DACH region (Germany, Austria, and Switzerland) demands arguably the world’s highest precision in construction documentation—specifically HOAI Leistungsphase 5 (Ausführungsplanung / Werkplanung) in Germany, SIA 102 / SIA 2051 in Switzerland, and ÖNORM A 6241-2 in Austria. SerMimar® bridges the severe DACH engineering capacity gap with disciplined LOD 350–400 BIM execution.

Because DACH projects frequently combine Revit MEP/Structural engineers with Archicad or Allplan architectural teams, our studio excels in lossless OpenBIM IFC4 Reference/Design Transfer Views, Schlitz- und Durchbruchsplanung (SuD / builder’s work openings), and strict DIN 277 / DIN 276 area and cost structuring.

TECHNICAL & COMMERCIAL Q&A

Frequently Asked Engineering & Commercial Questions

Direct technical answers on deliverables, ISO 19650 workflows, revisions, and fee structures.

Can you deliver true German HOAI Leistungsphase 5 (Werkplanung) detail depth?
Yes. Unlike schematic-only studios, our architects and engineers produce full 1:50 brick/concrete/drywall dimensioning, Rohbau vs. Fertigfußboden (OKRF / OKFF) elevations, lintel/sill heights (BRH), and 1:5 junction sheets following DIN CAD/BIM conventions.
How do you handle Schlitz- und Durchbruchsplanung (SuD) between MEP and Structural models?
MEP engineers place parametric Provision-for-Void families with fire-collar allowances; our BIM coordinators run clash/clearance rules and route each opening via BCF to the structural engineer for automated cut-out locking in the Schalplan (formwork plan).
Are your BIM models compatible with Archicad and Allplan teams via OpenBIM IFC4?
Yes. Because Archicad and Allplan hold major market share across Germany, Austria, and Switzerland, we rigorously map IFC property sets (Psets), IfcBuildingElementProxy elimination, and exact Survey Point coordinates.
Do you structure quantities according to DIN 276 Kostengruppen and GAEB-ready tables?
Yes. All architectural and structural elements carry DIN 276 3-digit Kostengruppen codes (KG 310–390) and DIN 277 room usage codes to feed directly into AVA tendering software (RIB iTWO, ORCA, California.pro).
Can DACH contractors also procure EN 1090 steel, facade systems, or EN 12810 scaffolding through your group?
Yes. Our group factories hold European CE certifications—supplying EN 1090 structural/LGS steel (SerBuild) and EN 12810 facade scaffolding (SerMimar İskele) by direct road truck to Munich, Vienna, Zurich, and Frankfurt in 4–6 days.
