Specific to the project, related to construction survey. Surveying belongs to the category of construction technology in the construction process, and setting out or providing elevation control points according to the drawings provides the basis for the construction of each working procedure. This work is very important, but ordinary on-site construction technicians can do it more or less, which is their basic skill. Except for deformation monitoring and settlement observation of foundation pit, which require professional equipment and professional qualifications, the construction survey and lofting work is completed by the construction unit itself.
As for the relationship with the cost, in the construction stage, other aspects have little objective influence except the elevation measurement of natural leveling at the start-up stage. Of course, if the measurement accuracy is too large or misplaced, it will definitely cause quality accidents. Let's just say that it is possible to tamper with the elevation measurement data during earthwork construction to affect the cost. In a word, this is a clear water yamen of the construction unit.
