Observations of the precipitation of buildings and structures of industrial enterprises are part of geodetic monitoring, which is carried out both during the construction of the facility and during the operational period. Systematic geodetic measurements in the framework of monitoring is of great importance to ensure the safe operation of the engineering facility and in some cases can pre-vent man-made accidents, environmental disasters. The article presents the results of determining the absolute values of sediment foundations of buildings, structures and equipment of one of the thermal power plants under construction. The peculiarity of the measurements on the object is the use of fan-shaped trigonometric leveling, which allowed to significantly speed up the implementa-tion of the field stage of work. Leveling was performed by electronic total station Leica TS-06 with the accuracy of measuring the vertical angles of 2ʹʹ. Residuals of closed polygons and field control measurements at the station showed high accuracy of trigonometric leveling, comparable with geo-metric leveling class II.
