Abstract
During the implementation of the structure project-ing on location, there is a need to prepare geodetic data and determining the accuracy and proper con-trol in preparation for the construction of engineering structures. These functions are performed by the engineering- geodetic monitoring. Тhe correct approach to determining the accuracy of area and transfer it to the correct method of calculating errors when performing measurements should be car-ried out using basic techniques and engineering-geodetic monitoring activities. Technically, moving project on location is an action opposite photo-graphing: during the shooting and planning, the contours of the terrain are put on the plan when you project the same design on location. Therefore, cor-rectness of the design projecting can be compared with precision shooting. If the design projecting on location use data (values of angles and lines), which is obtained by calculations when designing analyti-cal way, the accuracy on location will affect only error field measurements. Projecting the design on location as the final stage of the construction works to a large extent depends on the accuracy of loca-tion sites, parallelism or perpendicularity of their parties, the divergence of the actual space installa-tions on terrain with areas specified in explication. It is impossible to correct a geodetically inaccu-rately constructed project by a correctly chosen method of projecting the design on location; howev-er, an incorrectly chosen method of projecting on location can nullify the accuracy obtained during the design. Therefore, three geodesic processes — survey, design, and projecting on location — must be performed with appropriate accuracy. Given the inaccuracy in one of the processes, it is impossible to achieve the required accuracy for the project as a whole.
