Geodetic works in construction

Stages of work in support of construction:

  • Collection, analysis and detailed study of the construction project, the search for possible errors;

  • Creation and subsequent development of the geodetic reference network of the construction site, including the creation of a temporary geodetic network in the controlled territory, for which the coordinates of the points are calculated only by the results of geodetic construction;

  • Breakdown of the main axes of the construction site with fixing them on the terrain;

  • Breakdown of minor structural elements of the facility, including underground communication routes;

  • Breakdown of high-altitude benchmarks for construction and installation works;

  • Control and acceptance of the executive documentation of subcontractors;

  • Executive survey of the constructed elements and drawing up of executive drawings, including executive drawings of planned and high-altitude position of structures during construction;

  • Geodetic control over compliance with the geometric parameters of building structures, including installation of equipment, reconciliation of crane tracks and verifying the verticality of columns, structures and their elements, surface leveling and formwork;

  • At the final stage of the construction, a set of executive geodetic documentation for the delivery is prepared, containing: an executive master plan and schemes for components of structures and building elements, executive drawings and axonometry for overground and underground communications, special executive engineering plans, profiles and sections and cartograms;

  • Comparison of the obtained results with the project coordinates (elevations) and the coordinates of the same points characterizing the previous controlled horizon (in case of support for the construction of a multi-storey building);

  • Observation of deformations of buildings and structures, their bases, control of soil movements;

  • Preparation and delivery of a technical report on the results of the construction, geodetic works;

  • Accompanying excavation of excavations (embankment soil), with subsequent calculation of volumes of earth masses, compiling a cartogram, as well as calculation of the volume of construction work.
