While Elemental Cost Planning (ECP) is widely adopted in international construction, its integration with Building Information Modeling (BIM) remains underdeveloped in Sri Lanka. This study aims to address the absence of a standardised, automated, and NRM 01-compliant BIM-ECP solution by developing a functional Revit-based plugin capable of producing accurate, region-sensitive cost estimates. As the design …
