BIM-ENABLED PROJECT COST MANAGEMENT THROUGH THE PROJECT DELIVERY PROCESS

Abstract

THIS STUDY INVESTIGATES AND ANALYZES THE UTILIZATION OF BIM IN MAJOR MULTI-DISCIPLINARY CASE STUDIES, THROUGHOUT THE PHASES OF RESOURCE PLANNING, COST ESTIMATING, COST BUDGETING AND COST MONITORING AND CONTROL. THROUGH THE CASE STUDIES, THE AUTHOR SEEKS ELUCIDATIONS ON THE DISTINCTIONS BETWEEN CONVENTIONAL AND BIM-ENABLED COST MANAGEMENT METHODOLOGIES. THE FINDINGS SUGGEST THAT A BIM-ENABLED PROJECT COST MANAGEMENT PROCESS LEADS TO IMPROVEMENT IN WORKFLOW PRODUCTIVITY (MAN-HOURS), AND COST CERTAINTY AS COMPARED TO THE CONVENTIONAL COST MANAGEMENT METHODOLOGIES, AND THE EXTENT OF ADVANTAGES/BENEFITS VARIES ACCORDING TO THE DIFFERENT STAGES IN THE PROJECT DELIVERY PROCESS.

THE AUTHOR ALSO PROPOSED SEVERAL RECOMMENDATIONS TO MANAGE BIM-ENABLED COST MANAGEMENT. THE RECOMMENDATIONS INCLUDE FORMULATION OF A COST CODE LIBRARY TO MANAGE BIM COST DATA (TO BE UTILIZED RESOURCE PLANNING STAGE); A COST MANAGEMENT SOFTWARE PLUG-IN/ADD-ON (TO BE UTILIZED AT COST ESTIMATION/COST BUDGETING STAGE);
