Engineering environmental surveys are held on:

• territories of future buildings of buildings and structures;
• plots allocated for the necessary communications;
• territories allocated for improvement and gardening;
• plots where work is underway to recult territory;
• plots where territory and sanitary zones must be examined;
• sections where the restoration of water bodies and improvement of nearby territories are being restored.

Objectives of survey work for construction

Environmental surveys for construction are intended to evaluate the state ambient At the time of work. IEI are held in order to prevent, minimize or eliminate the harmful and unwanted environmental, social, economic and other consequences and the preservation of the optimal living conditions of the population. Based on the data obtained as a result of environmental surveys, an environmental rationale for construction works or other economic activities on the selected territory is created. Therefore, studies are held at the preparation of pre-project documentation. The result of engineering environmental surveys should be improved and improving the quality of the environment.

The tasks of engineering ecological surveys are determined by the peculiarities of the natural situation in the development area, the nature of the existing and planned anthropogenic effects and change depending on the stage of design and survey work.

Engineering environmental studies in construction are carried out for the following purposes:

• justifications of construction and other economic activities;
• reducing or eliminating the adverse effects of building construction;
• conservation of environmentally friendly areas suitable for people's stay.

Stages of engineering and ecological surveys

Highlight three main stages of engineering environmental research:

• Preparatory. The main task of the first stage of environmental surveys is to collect materials that reveal the features of the territory of the development. For this purpose, current indicators, reference and cartographic data are analyzed, as well as the results of the surveys of previous years. At the same stage, the survey organization receives a technical task from the Customer, the deadlines and the cost of research are established.
• Field. At this stage, the main part of the engineering surveys is performed: a visual examination of the area is carried out, the water and soil samples are taken, the air masses are studied, the radiation setting is given, gas-chemical research and laboratory work is carried out. Also, physical impacts (vibrations, noise and electromagnetic fields) are also studied at the field stage. Sanitary and epidemiological and medical and biological research are also obligatory. Based on the data obtained, experts constitute tables containing topical indicators of different spheres create the necessary schemes, form a database that will be needed for subsequent processing of materials.
• Cameal - the final stage of the survey. During the cameral stage, based on the data obtained, a report is drawn up that meets all the requirements. regulatory documents. The report contains conclusions about the state of soil, water and an air environment in the territory allotted for construction. It describes in detail the terrain, climatic conditions, Geological, soil, physico-geographical factors, flora and fauna, and also provide recommendations for environmental protection and reduce the negative impact on it. The report with the results of the research is based on the environmental rationale for the development and is necessary in the preparation of initial and permits.

In determining the type and volume of research for construction, the nature and degree of use of the site are taken into account before the survey. The conditions for research also affect the conditions: geological, sanitary and epidemiological and hydrogeological features of the place of future development, as well as the design stage, the nature of the anthropogenic effect on the territory allocated under construction, the specificity of the object, the volume of existing information about the territory. Therefore, each stage of environmental research allows for extensions. The sequence and duration of work in these surveys is determined in accordance with the existing standards and legal documents.

Features of work

Engineering works can only be carried out by special organizations, since to study water and soil samples, you need to have certain knowledge and skills, as well as have special equipment. In the course of engineering environmental work used super-sensitive devices. Thanks to modern research methods, it is possible to determine the amount of electromagnetic radiation on the ground, calculate the illumination parameters or the level of noise vibrations.

A feature of this type of work can be considered that it is quite difficult to determine the desired degree and detail of research. Therefore, an individual approach is distributed in environmental research, when the overall nature of the territory and history of its existence are studying, but only then begin directly to work.

Like any type of activity, these studies should be economical, that is, prevent unforeseen costs. However, their peculiarity is that they are not always easy to delimit the "unfounded" costs of "reasonable". Therefore, in this case, the guarantee of the design efficiency and, accordingly, construction and installation work, becomes complete and the details of the study of engineering and geological conditions. For all these reasons, surveys require special professionalism from performers.

All works are classified based on their goals. So, in the direction and specificity of activity, 3 main groups are allocated:

• Geodesic activities. Mandatory work before the construction of a real estate object, which includes the preparation of the topographic painting of the area. After collecting data, they are transferred to paper - make a drawing, general planning. The creation of the drawings is engaged in an engineer-geodesist, which studies relief of the terrain. Exquisition for the design of this species allows you to carry out vertical planning, plan the landscape design. Topographic surveys recreate the painting of the area near the object.
• Geological activities. Engineering and geological surveys are a set of actions at the initial stage of construction, which are aimed at assessing its expediency. The specialist studies the state of the soil so that you can define the appropriate type of foundation, features of fasteners and the design itself.
• Environmental activity. The specialist studies the environmental climate. If the risk factors are found, they are eliminated and the optimal conditions for construction are eliminated. The result of the survey enters permissive documentation. Indications are necessarily taken into account when drawing up projects.

The organization of engineering surveys in construction is completed by the document - permission to the commission for the construction of the facility. As a result, the developer receives all the data to create a safe, environmentally friendly object accessible to accommodation. If at least one of the types of research has not been fulfilled, the construction permit will not be issued.

Engineering composition

The engineering activity includes several studies. The territory is analyzed from an economic, technical and environmental point of view. Analysis is carried out to collect the full amount of area data.

Survey in construction - mandatory procedures when erecting the following types of objects:

• civilian;
• industrial;
• residential;
• road, transport junctions and others.

What enters engineering surveys, the following factors determine:

• how accessible and the object is studied;
• what are the scale of the planned work;
• for which the construction is intended;
• how will build construction?

The types of engineering surveys are combined into a single large-scale work of specialists. They carry out calculations that allow you to see the real characteristics of the terrain on paper. All data obtained is fixed and have legal force. Information about the territory is the basis for construction planning.

In addition to the above, there are other varieties of research that can confirm, refute or clarify the previously obtained data. For example, the external environment, the state of the soil, soil, underground water is additionally studied. The developer can get detailed results of laboratory analysis of all samples and samples.

Objectives and objectives of engineering surveys

Exquisitions are carried out in accordance with the requirements construction Rules and SNiP 11.01-1995 norms for the following purposes:

• get complete information about the plot;
• make a forecast for possible changes in the future;
• compile based on exact data volumetric layout;
• eliminate possible negative factors in construction;
• get an idea of \u200b\u200bthe natural potential of the site;
• take into account all the details when designing;
• create an object documentation with the designation of all accurate measurement data;
• establish a real estate interaction sphere with an external environment;
• make an object as safe and convenient as possible;
• improve the reliability, stability and operational properties of objects.

Also, engineering surveys allow you to track the relationship of the design of the object and the overall natural environment.

Thus, the survey in construction is a combination of mandatory procedures that are aimed at studying all the characteristics of the construction site. The results of the research are enshrined legally and the basis of the documents for construction.

Additional services

In addition to the main types of work, engineers offer and so-called additional serviceswhich emerges with controversial situations. They often appear in the construction of large objects.

The secondary research includes:

• geotechnical diagnostics of the territory;
• project on fact with initially obtained data - soil samples,
• the results of water analysis;
• identifying potential risks from man-made and natural cataclysms;
• creating a convenient engineering protection of an object from negative environmental factors;
• full examination during the entire construction period.

Additional services and expertise are carried out throughout the construction. The approach includes an analysis of the quality of construction, building materials. Analysis results are also fixed on paper. It is possible to contact her later if controversial situations arise or the case will reach the court.

Types of research

Allocate the following types of surveys:

• engineering and geotechnical - the study of the Earth, the composition of the soil;
• engineering and hydrological - analysis of the natural environment and features of the conditions of the territory;
• engineering and hydrometeorological - weather conditions of the district;
• engineering and environmental - environmental conditions;
• engineering and geological - natural medium in terms of geological activity;
• engineering and geodesic - sightseeing of the terrain from different angles;
• engineering and topographic - topographic shooting of a plot of future building and adjacent territory.

Economic and engineering and construction factors are also taken into account.

The final result of engineering surveys

Construction always begins with the creation of a project and studying the documentation, which engineers-geodesists are obtained as a result of a prolonged analysis of the site. The results of their work include:

• topographic survey with reflection of terrain, communications, engineering structures;
• geological report, including the specifics of the area and laboratory analysis of the soil;
• hydrological information about weather conditions;
• environmental assessment of water quality and air.

Planning and exercising engineering activities

Work, during which make up a detailed report, consists of several stages.

1. Preparatory Stage: Request of the developer or the owner of the territory, collecting primary information and appeal to archival data. Planning volume and duration of work.
2. Field activity: carrying out all types of work, ranging from geological and ending with engineering and technical surveys.
3. Cameral stage: analysis of the data obtained, systematization of information, drawing up documentation.

Procedure for Engineering Exquisites

All types of work that need to be held before construction starts only if there is a written tolerance to them. Tolerance is needed legal entitiesand individuals.

All preparatory work is carried out in order to:

• obtain data on the natural area of \u200b\u200bthe site and technogenic factors;
• take into account possible changes in the environmental side and develop a construction option with the maximum safety of nature;
• get information for documentary reporting.

Before starting work, you need to collect a package of documents:

• urban planning planning of the territory, documentary permission for land development;
• extract from unified Registry About the cadastral issue of one
• technical characteristics of the object.

The city planning plan is issued within a month after the request. After that, engineering surveys are carried out, make up the construction project, make a volumetric layout. The project is developed on the basis of norms Town Planning Code and other regulatory acts.

Then the long process of planning the construction or reconstruction of the object begins. All design options provide for consideration by the Commission, which coordinates the final result.

If the design takes up too much time, permission to connect engineering and technical networks loses legal force. In this case, the owner or developer appeals to the municipal authorities for a new resolution.

To avoid delays, when contacting you need to provide a number of information:

• the level of permissible load when connected;
• the period for connecting real estate.

The validity period of technical conditions is 2 years from the date of issuing permission.

Specifications also indicate the documentation, all the nuances are described in the contract. After choosing an organization, which will provide engineering and technical services, negotiate with the company that will be connected. Information about the timing and methods of payment and connection must be provided within 2 weeks.

Geological surveys give us the opportunity Technically justify the expediency, as well as the principle of construction of construction in a particular locality already at the design stage. In case there is a need to preliminary evaluation of the feasibility of construction in the selected area from an economic point of view, engineering and geological research becomes mandatory procedure Preparation before construction.

The relief features, the hydrological regime of the area of \u200b\u200bthe chosen development is determined by geological surveys. The mechanical composition of the soil, soil is also exposed to the study. With the help of the data acquired during the data process, the preparation of the tectonic and seismological characteristics of the area occurs. The forecast is also compiled. possible changes geomorphological, hydrological situations that are able to change after and in the process of building an object. The versatile engineering and geological study of the territory of the new building has the most important thing When designing a building. All this is carried out directly at the presenter preparation stages.

Engineering and geological surveys serve to calculate the reliability of the area allocated for construction. Naturally, this is carried out before the start of designing the foundation of the new object. The choice of the formation of the foundation of the building and the subsequent design is based on information on the physicochemical qualities of the soil and the hydrological regime of this territory (especially information about the levels of groundwater). In the event of a shortage or lack of such information, geological surveys increases the likelihood of errors and shortcomings of engineers during the design time of the project. The incorrect design of the foundation over time is able to apply for deformation, premature destruction of the constructed object.

The construction of a new object in the urban feature often occurs next to an existing building or building. Such a construction can lead to the modification of the geomorphological process in neighboring territories, which can cause already built buildings for deformation. The situation worsens also by the fact that the underground plot of the new building is often involved to create trading rows or parking for cars. The reconstruction of an existing building is very often associated with an increase in the burden on the foundation of the structure. This feature Development in the city requires a special, careful study of the plans of the planned construction and the choice of the territory corresponding to all necessary requirements safety.

Geological surveys have absorbed a lot of research areas:

• evaluation of archival information of similar studies in the territory of the planned construction (provided that there is such information);
• drilling geological well;
• selection of samples of soil and water for research in the laboratory. Study of the chemical, as well as the physico-mechanical properties of the material;
• geophysical study in order to detect the territory with an unfavorable geological composition, identifying underground communications, trails and other objects;
• study of the geological structure of this section of the land allocated for future construction;
• study of the hydrological regime, as well as the structure of groundwater and soil features in the studied area;
• detection of actual and potentially permissible processes that are dangerous to build a building, subsequent operation;
• geodesic binding of planned objects, as well as parallel engineering developments on the ground.

Geological surveys provide chance Get information based on which a technical report is created. This report is subject to approval in the MoscowGogotrest, as well as Mosoblgeotrest.

Studying materials from the archive on geological survey on the locality of the planned construction. The presence of information on the previously generated study of the territory of the planned construction provides the possibility of the maximum accurate mapping of the current geological process. Information about the dynamics of changes in the geological construction of the territory and its hydrological regime is mandatory for the forecast of further changes in geo-active, taking into account the impact of the future object of geossed. Drilling of geological well, samples and laboratory tests of material. The drilling of the well is carried out in order to intimidate the soil sample at various depths for subsequent laboratory analysis. In the laboratories, studies are conducted by the physicochemical properties of the soil, separately, its exchange and absorption properties, the tendency to shrink, swelling, osmosis, diffusion, as well as corrosive activity and some other qualities.

Geophysical work on the detection of a geologically unfavorable area, underground communication and other underground object can be through the study of data from the archive, as well as using the instrumental method. The study of the hydrological regime of the territory, the composition of soil groundwater and the characteristic of the soil, soil.

The purpose of the study is to study changes in the water object located on the territory of future construction. What is the effect of anthropogenic and natural factors on water objects. In the process of the study, the dynamics of possible modifications of water - channel, level, composition, temperature is also known.

Study of geological buildings of terrainin which will be carried out construction worksconcludes a complex for the analysis of the soil in order to obtain information on the chemical composition of the soil, as well as the definition of its geotectonic platform. Information on the features of the geological structure of the territory, also information of the hydrological regime is used to form the results of a devastating process that makes it difficult to build a building and representing the danger to its operation. The results in turn serve as the basis for the foresight of the subsequent development of the possible and detected occurrence, which was not previously seen in the geological process. The geodesic attachment of the object, as well as the accompanying engineering development to the territory, is necessary for the highest accuracy of geodesic surveys. Of course, this is relative to the reference point on the territory.

Studying the geological structure of the area in which construction work will be held Includes integrated soil and soil analysis to obtain data on the chemical composition of the soil and determining the geotectonic platform. The obtained data on the peculiarities of the geological structure of the site and the existing hydrological regime are used to form the statistics of destructive processes that impede the construction of an object and representing the potential danger to its operation. Statistics in turn serves as the basis for the forecast of the further development of the revealed and possible occurrence of previously recorded geological processes.

Physico-chemical characteristics of the soil Climbing in a table, which, as well as the topographic plan, is added to the technical report on advanced geological work. Reports are based on regulatory documents that regulate the amount of work. Further, reports are subject to coordination in the state institution of the Mosgorgeotrest and Mosoblgeotrest. For the implementation of geological surveys in the preparation (pre-project) future construction, the Customer organizes a technical task. This task is compiled in accordance with the requirement of clause 4.13 SNiP 11-02, as well as the topographic plan of the territory allotted under construction with an underground communication and a circuit of the planned building. In the presence of these documents, the program of geological surveys is formed. And already a complex of studying the territory under the construction of a new object is carried out on the basis of this program.
