设计变更对市政工程造价的影响与控制

On influence of design alteration on costs of municipal projects and its control

结合工程实例,分析了设计变更对于工程造价的影响,阐述了引起设计变更的原因及相关因素,在此基础上提出了设计变更的控制措施,即做好地质勘察、工程设计,并制定完善的管理制度,以指导工程造价人员通过控制设计变更有效控制工程造价。

Combining with the engineering examples, the paper analyzes the influence of the design alteration on engineering costs, illustrates the reasons for the design alteration and the relative factors, points out the controlling measures for the design alteration, such as geological observation and engineering design, and formulates the improved management system, so as to direct the personnel of the engineering costs to have the effective control over the engineering costs by controlling the design alteration.
