description: The work is devoted to the study of the application of geographic survey in construction, and the processing of data obtained as a result of geographic survey, as well as obtaining a reducing error coefficient of the processed surface points. The research set the following goals: 1. Performing aerial photography of the building. 2. Optimization of the building survey and monitoring processes with the use of photogrammetric technologies. 3. Development of a method of technological transformation of the coordinates of geometric samples of the object of study. 4. Apply the resources of BIM technology to the constructive representation of the building. 5. Development of recommendations for improving photogrammetric technologies of construction objects. 6. Performing calculations to determine the reduction factor. The geographic survey of the study was carried out on the object located at the address: 10 Khlopina Street, litera D, St. Petersburg, and is a flat land plot without significant height differences, on which there is a non-residential building with an area of 19,460 sq.m., provided with all necessary engineering communications (electricity, water supply, sewerage, heating). In the course of the study, all the necessary information was collected: the identification of the object, the photo of the object, the area of the land plot. After receiving the initial data, they were processed in the Agisoft Photoscan and Civil 3D software. On the example of processing the obtained data, the algorithm of the process of obtaining the coordinates of the surface points was developed and a reducing error coefficient was developed. As a result of the work, it was proved that when processing surface data, an error occurs, which, with large objects of research, can adversely affect the course of design, construction and reconstruction of the object itself. The resulting coefficient will help to avoid these consequences.
