Establish length and coordinate benchmarks for quality inspection and measurement of water conservancy engineering:

In order to ensure the length standard of water conservancy engineering construction measurement, it is required that length measuring instruments and tools such as rangefinders and rulers should be regularly and comprehensively calibrated and used within the validity period of the calibration. For large-scale water conservancy projects, due to the large number of construction units and long construction period, in order to facilitate the calibration of distance measuring instruments, a baseline field can usually be established in the vicinity of the construction site using precision measurement technology and methods. After metrological certification, it can be used as a length benchmark. All length measuring instruments and tools such as rangefinders and rulers used in the project, whether for construction layout measurement, engineering supervision measurement, or quality inspection measurement, must be regularly inspected on the baseline field. For example, the Tumen baseline field near Yichang is the length benchmark for measuring water conservancy projects such as the Three Gorges, Gezhouba, and Geheyan.

The construction control network is the benchmark for construction surveying. One of the purposes of establishing a construction control network is to establish a construction coordinate system at the construction site, and to maintain this coordinate system through the re measurement or expansion of the construction control network during the construction process, providing a unified coordinate benchmark for engineering construction. Of course, this is also the coordinate benchmark for quality inspection and measurement.
