用实物法计算施工机械生产率和运行效率

Object method used to calculate productivity and operation efficiency of construction machine

实物法将逐渐成为我国工程造价管理的发展方向。采用实物法估算工程造价，一个关键步骤是计算施工机械的劳动生产率和运行效率并对机械进行配置。本文通过工程实例的计算分析对其原理和方法做了简要介绍，以期促进该法在工程中的进一步推广应用。

The object methods will gradually becoming a development direction of project cost management. A key step is the calculation of productivity and operation efficiency for construction machine and equipment disposition in computing project cost by the method. The paper briefly introduces the principle and the method of this calculation through the example of project to promote the popularization of this method in project management.
