Engineering and geodetic surveys are necessary to ensure a comprehensive study of the natural and man-made conditions of the territory (region, district, site, site, road) of construction projects, making forecasts of the interaction of these objects with the environment, the justification of their engineering protection and safe living conditions.
The main task of engineering and geodetic surveys is to obtain topographic and geodetic materials and data on the situation and terrain (including the bottom of watercourses, water bodies and water areas), existing buildings and structures, utilities (land, underground and aboveground), elements of the layout in digital , graphic and other forms necessary for a comprehensive assessment of the natural and man-made conditions of the construction site and the justification of the design, construction and operation of facilities.
The composition of engineering surveying:
reconnaissance survey of the territory;
creation (development) of reference geodetic networks, including special purpose geodetic networks for construction;
the creation of planning and high-altitude survey geodetic networks;
topographic survey, including the filming of underground and aboveground structures;
updating of topographic and cadastral plans in graphic, digital and other forms;
engineering and hydrographic work;
geodetic works associated with the transfer to nature and the binding of mine workings, geophysical and other points of engineering surveys;
geodesic stationary observations of deformations of the foundations of buildings and structures;
engineering and geodetic support of information systems of settlements and state cadastres (town planning, etc.);
office processing of field materials;
drawing up a technical report.
