Integration of IDS, bSDD, and BCF for bidirectional quality control.
Validation demonstrated improved data readiness before quantity take-off.

Abstract

• A requirement-driven openBIM workflow supports information verification for cost estimation. • Information requirements are formalized into machine-readable IDS specifications. • IDScribe enables automated semantic enrichment of IFC models in Blender. • IDS, bSDD, and BCF are integrated for bidirectional quality control. • Validation shows improved data readiness before quantity take-off.
