Survey work is, first of all, the identification of technical grounds for preparing for the start of construction, engineering surveys, development of construction projects, preparation of working and estimate documentation. This set of works can be carried out both during capital construction and during the reconstruction of structures, the need for their technical re-equipment.
Classification
Currently, design and survey work is conditionally divided into several types:
- Topographic and geodetic work - aimed at collecting and providing data when compiling situational maps of a particular area. Preparing maps and detailed plans allows engineers to gain a basic understanding of the existing terrain and identify potential problems that will be faced during construction.
- Geological survey work is the study of the geological features of the structure of the working area, the characteristics and qualities of soils.
- The third type of survey work - hydrological surveys related to thedesign. Such activities include determining the location of groundwater, studying its quality, origin, suitability for technical needs and drinking, diagnosing the aggressiveness of the composition.
The main tasks of survey work in preparation for construction
Performance of survey work allows to solve the following series of tasks:
- preparation of a developed geodetic network for construction needs;
- updating scale plans, topographic schemes;
- preparation of terrain plans in graphic and digital, three-dimensional version;
- collection, processing and analysis of available data about the object;
- assessment of the site, measurements, measurements;
- processing the information received, drawing up work sheets, conclusions, reports.
How to place an order for survey work?
If it is necessary to perform survey work, it is important to seek help from reputable services that have experienced trained specialists. Having decided on a construction company that is capable of performing design and survey work with high quality, it is necessary to correctly set the main and secondary tasks. Next, a program of necessary activities is determined and agreed upon.
The cost of survey work is formed on the basis of documentation with a list of pre-planned tasks, which contains information about the amount of work required, their nature, timing. At the end of the partyagreements receive a package of necessary papers.
Preparatory work
During the preparatory stage of survey work, first of all, technical tasks are set, design documentation is prepared. As a basis for the implementation of such activities, sets of existing materials on the object for past periods are usually used. However, the project can be developed based on fresh data.
Further, on the basis of the processed information, a program is prepared for carrying out survey work in accordance with the tasks set. Official permissions required to implement scheduled tasks are issued.
Field work
Field survey work is the most important stage that requires the formation of objective data, on the basis of which important calculations are made, plans for sites and objects are drawn up, and reporting papers are prepared.
At this stage happens:
- survey of the area;
- a general work plan is outlined;
- important areas are identified for the technical and material support of the planned events;
- a reference geodetic grid is organized;
- topographic survey of the area is in progress, as well as existing underground utilities;
- the project is taken out in kind, after which the relevant acts are drawn up.
Camera events
Desk surveywork is a whole range of tasks, which includes the final processing of the results obtained during the research, the calculation of coordinates, the evaluation of measurements and, first of all, their accuracy.
Based on the results of cameral events, a digital model of the object is developed, on the basis of which the drawings necessary for the implementation of the tasks are created. It provides comprehensive information about the site, existing facilities, terrain, underground and surface utilities.
Final stage
At the end, a technical report is prepared, which contains detailed information about the object. The text part based on the results of office work must necessarily contain all the necessary drawings.
