Implementation of comprehensive engineering surveys at the Obukhiv GDS facility
A complex of engineering-geodetic and engineering-geological surveys for the development of project documentation (stage "Project" and "Working documentation") for the object: "Reconstruction of metering, gas purification and switching units of the gas distribution station "Obukhov" in the Obukhiv district of the Kyiv region was performed in January 2025. in order to obtain initial data.
The project provides for the following works:
- construction of a protective structure;
- installation of new equipment for gas metering, purification and switching units, pipelines and engineering networks at the GDS;
- replacement of shut-off valves for switching and reducing units;
- installation of the GDS automatic control system;
- dismantling of equipment and engineering networks of the existing GDS that are not used after reconstruction;
- landscaping of the territory;
- installation of insulating sleeves.
As part of the engineering and geodetic works, the following was performed:
- planned-height geodetic base;
- survey network;
- topographic survey at a scale of 1:500 with a relief section of 0.5 m of all technological objects of the GDS that are part of the GDS;
- control determination of the planned-height position of points of the planned-height geodetic base of previous years in order to detect landslide processes;
- topographic survey of the route of ground, above-ground and underground pipelines and other underground communications.
Among the engineering and geological works, the following were carried out:
- engineering and geological (hydrogeological) reconnaissance (route observations) with good passability;
- drilling of wells up to 20m deep;
- soil sampling for laboratory research, groundwater sampling;
- a reduced set of physical and mechanical properties of soils, chemical analysis of water, optimal humidity and density were determined.
At all stages of the work, technical quality control and acceptance of the completed work were carried out in order to check them at all stages of the technological cycle, compliance with the requirements of current regulatory and technical documents, compliance of the results of the completed work and their registration in accordance with the requirements of technical and technological instructions and the technical task, determination of the degree of readiness of the manufactured materials and their suitability for further design and for transfer to the Customer.
The resulting materials of the prospecting work were summarized in a technical report, which was prepared and transferred to the Customer.
