在工程实施过程中,如何加强工程设计变更和工程签证的管理工作（In the process of engineering implementation, how to strengthen the management of engineering design change and project visa） In the process of engineering implementation, how to strengthen the management of engineering design change and project visa? [Abstract] a project to easily control the cost, in the project implementation process, the most important is to control the good management of engineering design changes and visa, because has been the blueprint for the design and optimization of evaluation in the early stage of the owner or the construction unit cost has the ideal control range, so to control the the construction unit cost, formulate measures for the management of design change and engineering visa in the project before the start, in order to have rules to follow in the implementation. [Key words] design change engineering visa management First, correctly understand the meaning and content of design change and engineering visa, and give definition Design change: design change is to ensure the quality of design and construction, improve the engineering design, the design of correct design errors and meet the site conditions change and modify the work, including the proposed by the construction units, design units, supervision units, construction units and other units of the design change. Once the design document has been examined and approved, no unit or individual may change it at will. Because of the change of the construction condition of the project or the actual construction needs, the original design must be thoroughly investigated and fully demonstrated, and all the provisions in the project contract must be observed. The design of the unit owners proposed change mainly involves: approved construction scale, basic principles, main technical standards, the main function of system, main part, has a significant impact on the external group landscape, main function and main construction scheme, such as the overall layo
