Toward Automatic Calculation of Construction Quantity Based on Building Information Modeling

The application of BIM (Building Information Modeling) technology in practical engineering becomes more and more frequent. The current research on quantity calculation based on BIM discusses the cost estimation of the building projects. There are few methods that can query construction quantity during the design process which facilitates the designer to modify the relevant data at any time. In view of the present situation, this paper describes a calculation construction method on Revit platform, which is one of currently the most popular BIM modeling platform. The effectiveness and disadvantages of the approach are analyzed through a practical engineering example. With this method, designers can get real-time quantity in the design process in any time, and the design results can be checked and updated automatically based on statistics result of engineering quantity when necessary.
