Examines cost estimation accuracy in construction using information-driven BIM workflows, suggesting improved data readiness.
• 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.
