设计变更是影响工程建设进度和造价的重要因素,是工程项目建设单位、设计单位、施工单位等各参建方重点关注的环节,是工程施工活动中的重要构成元素。控制和减少设计变更需要工程项目各参建方的共同努力,本文从设计变更的分类、发生原因、应对措施及建议等方面对电力工程建设设计变更原因进行分析,探讨目前设计变更发生和控制所面临的主要问题,提出控制和减少设计变更的思路和措施。 Design change is an important factor that affects the progress and cost of construction. It is a key point of attention of construction parties, design units and construction units, and is an important constituent element in construction activities. Controlling and reducing the design change requires joint efforts of all parties involved in the project. This article analyzes the reasons for the change of design and construction of power engineering from the classification of design changes, the causes, countermeasures and suggestions, and discusses the current design changes and control Face the main problems, put forward ideas and measures to control and reduce design changes.
