摘要: 机电设备变更对地铁建设成本影响较大。通过对广州市轨道交通某线路车站设备安装工程91份工程变更单的实证分析,本文发现了轨道交通机电设备安装工程变更的一些规律与问题。变更数量和金额方面,整体呈现出变更数量多但是各项变更金额小的状态。其中,最大的单项变更涉及金额也不足100万元。引起变更原因方面,设计因素占据主导,比例达到总量的五成。其次是业主和外部协调因素。变更金额分布方面,安装专业的变异最为剧烈,建筑和装饰专业的变异相对温和。整体变异系数为1.18,离散性较大。审批流程方面,审批时间与变更金额表现出低度的线性相关性。为了加强机电设备变更金额的控制,同时提升合同变更管理的效率。建议地铁建设部门强化设计阶段的管理,重点关注安装专业的变更,简化小金额变更审批流程,适度控制10万元以上变更单的审批。进而减少变更对项目建设的影响,保证地铁项目建设的顺利进行。
Abstract: Changes of electromechanical devices have an influential effect on subway construction costs. This paper finds some laws and problems after empirical studying 91 engineering change orders of the station equipment installation engineering in Guangzhou metro. On the quantity and charge, the changes show a large quantity and a low charge. The charge of the biggest single change is less than 1 million Yuan among them. On the reasons, the design factor occupies the dominant position; its proportion is up to 50% in the total. Second is the coordinate factor between the owner and the external. On the distribution of the charge, the variation of the installation engineering is the most intense. The variations of the construction and decoration engineering are relatively mild. The coefficient of variation is 1.18; it has a large discreteness. On the approval process, approval time shows a low linear correlation with the changed charge. In order to strengthen the control of the changed charge and increase the efficiency of the contract change management, we suggest that the metro construction department should enhance the management in the design phase, focus on the change of the installation project, simplify the approval process of the changes which have a small charge, and control the approval process of the changes whose charge is above 100000 Yuan. After these, the impact of the changes on the project construction will be reducd. And the metro project construction will likely go on smoothly.
