Construction project cost control is a key link in project management.BIM technology can realize the whole process cost management from design,construction to operation and maintenance.Its three-dimensional modeling and information integration can reduce the conflict between design change and construction,optimize material statistics and engineering quantity calculation,and improve accuracy and efficiency.The visualization and collaborative functions of BIM technology make cost control more transparent and real-time,and promote lean management of construction.Therefore,the cost control method based on BIM can improve the scientificity and operability of project cost control.
