Recently, the applications of BIM (Building Information Modeling) technology has raised, and to subvert the traditional civil engineering processes and methods, which can be applied to all stages of the building’s life cycle and improve the construction efficiency and quality of the overall project. The average cost of building of the hospital is higher than the general building, and the amount calculation of materials will affect the overall construction cost. However, most of the large-scale and complex projects, in order to improve the procurement efficiency and quality to avoid the problems such as disputes between design and construction interface, difficulty in clarifying rights and responsibilities, difficulty in handling design changes and so on. Therefore, bidding is mostly handled in a turnkey way. The turnkey project is designed and constructed at the same time, which also increases the tedious and repetitive work of engineering quantity calculation. In recent years, there have been many researches and discussions on the application of BIM in the quantity take-off. But the application in practice is less, in addition to the limitations of the function of the software itself, and the valuation methods are also different according to the project, especially the hospital engineering project is complicated and most of the quantity take-off results are only used for assisting engineering check. This research takes the major medical equipment space of the hospital as a case study. BIM quantity take-off module can only automatically calculate the amount of all the structure elements, but also produce the required amount and chart for using in cost valuation, which can help us understand the cost of the hospital's important space for reducing unnecessary cost waste. This study takes the advantage of BIM technology, objectification and parameterization, to analyze and calculate the quantity information of the project, and can also effectively to execute the communication and integration applications through the visualization of BIM models, so as to improve the efficiency of the schedule control and cost valuation for the research case in the construction stage.
