Geological engineering surveys
are required in construction to ensure accurate and correct location of buildings and structures. These surveys are performed without regard to the type and dimensions of the facility under construction. Geological engineering surveys identify engineering-geological and hydrogeological conditions of the expected construction area, hazardous geological processes and other possible complications in the process of construction and operation of structures.
Scope of geological engineering surveys:
- collection and processing of survey materials of prior years;
- survey of foundation soils of the existing buildings and structures;
- excavation; field soil surveys;
- geophysical surveys; hydrogeological surveys;
- laboratory examination of soils and ground waters; fixed observations;
- office processing of the materials;
- forecasting of changes in the engineering-geological conditions;
- assessment of hazards and risks from geological and engineering-geological processes;
- generation of a technical report.
To obtain a positive opinion on design documentation from the state expert panel, we ensure the fullest scope of geological engineering surveys, as provided in the regulatory system.
Apart from that, within the scope of the geological engineering survey complex we perform the required geological engineering studies.
Environmental engineering survey
complex depends on the design stage, and is defined in SP 11-102-97. The scope of the surveys must be sufficient to develop urban planning documentation, Environmental Impact Assessment (EIA) in justification of investments, and Environment Protection section in the construction project.
The main objectives of geological engineering surveys are as follows:
Geodetic engineering surveys
- study natural and man-caused conditions in the territory, economic use and social sphere in the territory, where the facility is located;
- assess the current condition of the environment components in the given territory (ground and surface waters, soils, atmosphere air, biota), signs of physical risk factors (noise, vibration, electromagnetic field levels), and epidemiologic situation;
- identify adverse natural and man-caused factors;
- forecast possible negative environmental consequences in the process of construction and operation of the facility, and develop mitigation or prevention measures;
- prepare data for environmental justification of design documentation, and development of environmental impact assessment (EIA) materials.
are an important part of the studies required for further performance of construction works.
The data obtained are a basis for design and development of the required design documentation.
Analysis and assessment of measurements help to determine safety of the future structure and forecast probable violations in its operation.
Geodetic works are a range of measures aimed at obtaining the most accurate information on the condition of the expected development site. These are performed in several stages. The first stage is the study of the existing information and documentation about the territory. The second stage involves commencement of real terrain study. Specialists must perform a full study, including topographic and geodetic surveys. At the third stage, all the obtained information is analyzed, and a topographic plan is made. The result of the work performed is a technical report.
Full range of geodetic engineering surveys includes the following:
- control, as-built and topographic surveys;
- geodetic façade surveys;
- geodetic and geotechnical monitoring;
- landslide mass mapping;
- geodetic construction support.
