The construction survey of the technical condition of buildings, structures and engineering systems is a comprehensive analysis and assessment of the current condition of the object, including the condition of the foundation soils, building structures, engineering support (equipment, pipelines, electrical networks, etc.). Based on the data obtained, the operability of the object of inspection, operational characteristics and the possibility of its further operation, reconstruction, the need for restoration, reinforcement, and repair is established. Using expert analysis, further forecasting of the causes and consequences of the identified deficiencies is carried out. Taking into account the characteristics of soils, deformation damage, defects of load-bearing structures, the actual bearing capacity, technical condition of the building (structure), its individual parts and elements are determined.
EUCLID conducts a technical inspection of buildings, structures and engineering systems in accordance with the requirements of standards, regulations and technical regulations of Russia. Among them: GOST 31937-2024 “Buildings and structures. Rules for inspection and monitoring of technical condition” and SP 13-102-2003 “Rules for inspection of load-bearing building structures of buildings and structures”, which provides a systematic and reliable approach to assessing the technical condition of buildings and structures.
Determination of the technical condition of structures and elements, wear of buildings, structures and engineering systems is carried out:
- to develop a project for dismantling, modernization, reconstruction, reinforcement, overhaul of the facility and redevelopment of premises;
- during the reconstruction – the superstructure of floors or attics, the arrangement of the operated attic space, the deepening of the basement and basement floors, the installation of new floors, the change of functional purpose, the placement of additional equipment on the floors and roof, increased loads;
- when a building or structure falls into the zone of influence of new construction or reconstruction – calculating the impact of new construction or reconstruction, assessing the impact and analyzing the causes of defects and damage;
- when resuming unfinished (frozen) construction, determining the volume of work performed and the possibility of completing the SMR;
- to obtain an opinion on the compliance of the constructed or reconstructed capital construction facility with the requirements of technical regulations and project documentation, in order to legalize construction, obtain a ZOS and put the facility into operation;
- to develop or restore missing (missing) project and executive documentation;
- to monitor the condition of the object during scheduled and extraordinary inspections, to determine the causes of deformations of building structures;
- to determine the degree of deformation of building structures after accidents, accidents, natural and man-made disasters.
OUR EXPERIENCE IN THE SURVEY
According to the composition of the work, which allows to make an assessment of the technical condition, the survey is divided into two stages:
- visual inspection of buildings and structures is carried out to assess the technical condition only by external signs. Further, based on the results of the visual examination, the need for additional research is determined and a program is drawn up for a detailed examination, including a description and scope of work necessary to clarify the technical condition of the building;
- a detailed survey of buildings pursues specific goals – from determining the possibility of reconstruction with the addition of additional floors to determining the causes of cracks in load-bearing structures. Consequently, the composition and volume of field work on autopsies, pits, instrumental tests, as well as the volume of laboratory research and engineering calculations are determined individually for each object, depending on the objectives pursued and the design features of the building.
Field work – the procedure and composition of the work:
- preparatory work – preparation of the survey program; establishment of sites for opening structures, excavation of pits, sampling for laboratory tests; coordination of the work program;
- visual inspection of building structures and engineering systems, identification of defects and damages. fixing their places for further detailed instrumental examination with determination of their parameters – the size of the opening and extent, area and depth (cracks, delaminations, chips, pores and shells, areas of soaking and destruction, rolls, deflections and deformations), photofixation of defects;
- measurement work – determination of geometric parameters of structures and space-planning solutions of premises and structures, sections of individual elements;
- geodetic control – determination of deflections and deformations of large-span structures, rolls, subsidence of the building and changes in the position of structures;
- control of concrete and reinforced concrete structures – determination of strength characteristics, flaw detection and determination of the uniformity of concrete, the thickness of the protective layer of concrete and the diameters of the working reinforcement, analysis of corrosion and tension strength of reinforcement (by non-destructive and destructive testing);
- instrumental control of metal structures – welds, bolt tightening torque;
- opening of structures – opening of reinforced concrete structures to determine the condition, quantity and diameters of working fittings, floors and roofs to determine the condition, composition of pies. wall probing;
- excavation of pits for inspection of foundations and foundation soils;
- georadar study – determination of pile lengths and defects, detection of decompression and inhomogeneities in the soil mass and foundations;
- laboratory tests – selection of cores from reinforced concrete structures to determine the concrete class; selection of bricks, stones and mortar plates to determine grades; sampling of reinforcement and metal to determine chemical analysis and calculated tensile resistance; sampling of soil from pits to determine physical and mechanical characteristics.
Desk work – the procedure and composition of the work:
- development of drawings – floor plans, floor plans, sections, facades, junctions of structures, schemes of engineering systems and elements, detailing schemes of opening of building structures and sinking pits;
- development of maps (diagrams) and lists of defects and damages – determination of the type of defects, causes of formation and methods of elimination;
- analysis of instrumental tests and laboratory research materials – description of the test methodology;
- determination of the strength characteristics of the elements of the physico-mechanical and strength characteristics of structures and foundation soils taken into account during the verification calculations;
- carrying out verification calculations of structures and elements – thermal and acoustic calculations, collecting loads and determining forces; calculations on the strength and stability of individual most loaded structures or a full-fledged building model, determination of load-bearing capacity reserves;
- drawing up a technical conclusion – an explanatory note describing the design scheme, methods of work, research and testing results, conclusions and justifications about the accepted categories of technical condition, the possibility of reconstruction and other purposes, recommendations for eliminating defects, restoring load-bearing capacity, strengthening structures and further safe operation for functional purposes.

The scope of the technical survey work may differ from the one presented above and is determined based on the goals and objectives set by the Customer. The scope of work depends on the design features of the building or structure. Depending on the initial characteristics, we always choose an individual approach to each Project, choosing the optimal program of activities excluding unnecessary costly positions.
The main task of the survey is to determine the categories of the technical condition of individual load-bearing structures and soils of the foundation and the building as a whole, to determine the degree of wear and operational characteristics of engineering systems and other elements of the building. A precisely defined category makes it possible to develop correct recommendations aimed at strengthening, restoring structures and foundation soils and carrying out work aimed at further safe operation. The category of technical condition is established based on the analysis of the results of the study, verification calculations performed taking into account the updated design scheme, strength characteristics of materials, current and planned loads, as well as taking into account the impact of identified defects and damages.
In accordance with the requirements of GOST 31937-2024, which is the main regulatory document in the field of technical inspection, there are four categories of technical condition:
- normative technical condition – the estimated parameters meet the requirements of the project documentation or regulatory documents;
- operable technical condition – some parameters do not correspond to the design documentation or standards, but the bearing capacity and stability are provided;
- limited-operable technical condition – damage has been identified that reduces the load-bearing capacity, but does not lead to sudden destruction or loss of stability;
- emergency condition – the load-bearing capacity is exhausted and there is a danger of collapse.
Based on the results of the conducted complex of studies, a conclusion is drawn up on the survey or comprehensive survey of the technical condition of the object, as well as a passport of the building (structure) in accordance with the requirements of GOST 31937-2024.
The cost and timing of the survey depend on a number of key indicators, including the technical and economic parameters of the facility, the goals and scope of work required to implement the tasks set, and is calculated individually for each project.
Over the years of his professional activity, EUCLID has collected a significant amount of statistical data on the labor costs of work performed as part of a survey of various facilities.
