IFC-based Cost Estimation: Application to A Structural Model

Abstract: Accurate cost estimation is an essential factor in the success of any construction project. Based on previous work, this study aims to use the IFC data model to support cost estimation processes and reduce human error. Through a code, developed in IfcOpenShell, a cost estimation has been made in IFC associating the new IfcCostItems with the IFC 3D model objects. The study was validated by applying the methodology to a real case of a structural model and defining a cost schedule for the structural project. Ultimately, this study seeks to support, verify, and improve public tenders quality of cost estimates.
