Completion surveys involve the surveying work carried out upon the completion and acceptance of various construction projects. The results of completion surveys are the comprehensive layout plans, which include the current topography, buildings above and below ground, and the plan locations and elevations of various pipelines, as well as various professional drawings. The comprehensive layout plans reflect the actual conditions post-construction of the overall layout plan and are a crucial basis for project acceptance. They also serve as significant technical data for reconstruction and expansion of the project post-completion. Therefore, the engineering unit must place great importance on completion surveys.
Completion measurements are not only the basic basis for accepting and evaluating whether the project is constructed according to the plans, but also the basis for management, maintenance, renovation, and expansion after the project is put into use. Therefore, the completion drawings and documents are important technical archives of national key construction projects, and must be drawn and organized in accordance with regulations, and preserved for a long time.
