abstract={The construction industry faces persistent challenges in cost control, schedule reliability, and data consistency, particularly during the structural phase of high-rise buildings. Although Building Information Modeling (BIM) offers the potential to integrate quantities, costs, and schedules, its operational application remains limited due to the lack of standardized modeling practices and weak alignment between digital models and conventional cost–schedule structures. This study addresses this gap by developing and validating an operational, model-centered integration method that embeds a common itemized structure directly within the BIM model to support consistent cost–schedule integration. The research adopts a quantitative, applied methodology comprising four phases: (i) diagnosis of conventional ERP-based practices, (ii) design of a common itemized structure, (iii) iterative development of a parametric BIM model, and (iv) comparative evaluation against traditional workflows using data from real high-rise projects. The results demonstrate substantial improvements in traceability, automation, and data consistency, increasing cost–schedule coverage from approximately one-third of the items to over 95%. These findings show that effective 5D integration depends primarily on semantic structuring and standardized modeling logic rather than increased geometric detail, providing a practical and replicable approach for improving cost–schedule integration in structural works. },
