establish measuring control network; 2, set the vertical and horizontal centerline; 3, set the elevation benchmarks; 4, setting settlement observation point; 5, installation process measurement control; 6, the measured records, etc. Six figure drawing, engineering survey completion (a) the purpose of drawing completed master plan Completion is the total floor plan design master plan in the construction of the fully reflect the actual situation after, so design master plan cant completely replace the total plan completion. The purpose of compilation completed master plan: (1) in the construction process may be due to the design without considering the problems and make the design change, this kind of temporary change design must be completed by measuring the reflection to the total floor plan; (2) it will facilitate later for a variety of facilities maintenance work, especially the underground pipeline take cover engineering inspection and maintenance work; (3) the expansion of for the enterprise provides the original buildings, structures, and on the ground, underground pipeline and traffic line coordinates and elevation data. New business completed total floor plan compilation, preferably with engineering gradually completed successively for compilation. Completion and use of completion measurement results compilation site plan completion. If any problem found the location of the underground pipeline, may at any time to check and make record drawings can reflect the actual situation. Completed the advantage of compilation is: when business is completed, completion of the total floor plan also completed most of the compilation, can be used as completion of acceptance of the data, and can greatly reduce the measured workload, save manpower and material resources. Completion of site plan compilation, including both measured data compilation and indoor and outdoor. (2) measurement record drawings 1. Mechanical and electrical engineering survey record draw
