The paper describes the features of construction and monitoring in cultural and historical heritage areas using the example of the railway bypass of the Inkerman St. Kliment Monastery. The analysis of the current regulatory documents regulating activities in this area is carried out. The stages of geomonitoring are described. The geodetic component of monitoring is considered, taking into account the requirements established by the current legislation.

Keywords: geomonitoring, construction, cultural heritage site, leveling, railway track, deformation grade, precipitation and deformations

The analysis of accuracy in obtaining geospace information while monitoring railway infrastructure objects by different methods such as geodesic, photogrammetric and remote sensing is carried out in the article. Tachymeter and global navigation satellite systems are used as geodesic methods. Aerial photography by means of unmanned aerial vehicles are referred to photogrammetric methods. Remote sensing was carried out on the basis of 3 D laser scanning technologies. The accuracy of performed measurements is considered for the scale 1:500.
