轨道交通包括地铁、轻轨等,是大城市现代交通发展的方向。大城市的土地资源紧缺、地面交通拥塞,而发展城市轨道交通,既可解决这些问题,还可实现交通的高效、安全、舒适。然而,城市轨道交通的造价高、施工复杂,因此在工程施工中,过程管理就成为施工企业的重中之重。工程项目的成本控制提高过程管理水平,应从项目成 Rail transit, including the subway, light rail, etc., is the direction of the development of modern transportation in the big cities. Large cities have scarce land resources and traffic congestion on the ground. Developing urban mass transit can solve these problems and make transportation more efficient, safe and comfortable. However, the cost of urban rail transit is high and construction is complicated. Therefore, in the process of project construction, process management becomes the top priority of construction enterprises. Project cost control to improve the process management level should be from the project into
