Technical inspection of buildings and structures

Our experts have extensive experience and qualifications, have at their disposal all the necessary resources, including the laboratory of destructive and non-destructive testing. We are ready to carry out all types of technical inspection on any, without exception, objects.

We conduct surveys of buildings and structures in Moscow, Kaluga, Tula, Voronezh, Nizhny Novgorod and other cities of Russia.

Judicial and non-state construction expertise "GARANT EXPERT" carries out a comprehensive technical inspection - a comprehensive analysis of the state of buildings, building structures, foundations and foundations, engineering systems of a construction object to detect external and hidden defects and damage.

Why do technical inspections of buildings?

During the operation of buildings, due to various reasons physical deterioration of building structures, reduction and loss of their bearing capacity, deformation of both individual elements and the building as a whole occur. To develop measures to restore the operational qualities of structures, it is necessary to conduct their examination in order to identify the causes of premature wear and lower their carrying capacity.

Work on the survey of buildings is an analytical comparison of the project documentation available to researchers with the data of visual and instrumental analysis obtained in the process.

The objectives of the survey are to make sure that the object is not in an emergency condition and does not endanger users and others, identify defects, determine the need for repair and / or replacement of part of the structures.

When do I need to conduct a technical survey?

Technical inspection of buildings and structures should be carried out in the following cases when:

  • reconstruction associated with add-ons, installed engineering equipment, basement recesses, redevelopment or refurbishment of a building when the functionality changes associated with an increase in temporary operational loads
  • overhaul with the replacement of structures or redevelopment of production facilities;
  • detection of various kinds of defects and damage that reduce the carrying capacity
  • loss of the original properties of the structures of buildings and structures (physical deterioration);
  • the results of natural disasters, accidents and fires;
  • the expiration of normal operation, the lack of continuous maintenance of structures and structural elements in good condition, not compliance with the required temperature and humidity conditions in the premises, not timely maintenance of engineering equipment and technical systems;
  • the expiration of the previously completed technical opinion;
  • obvious deviations of structures (deflections of beams and floor slabs, vertical displacement of columns) from design positions, determined visually without the use of special devices;
  • legalization of a building or structure, as well as extensions made without a specially designed project;
  • lack of design and executive documentation;
  • general survey of unfinished construction sites;
  • designing objects of increased complexity;
  • construction monitoring of objects related to cultural heritage;
  • obtaining permission before commissioning.

What works are carried out in the framework of technical inspection of buildings?

Technical inspection of buildings and structures includes works on the ground survey of the foundation, load-bearing building structures (foundations, walls, columns, floor structures and roofs, roofing, roof-bearing structures, stairs), joints and subassemblies of parts of structures, floor structures, roofing , window and door fillings to determine changes in their properties during operation, identify defects and damage, deficiencies and determine the actual bearing capacity of the bearing structures ktsy building.

The frequency of the survey is specified in GOST. According to the document, a survey of buildings should be carried out:

  • no later than two years after commissioning;
  • once every ten years under normal operating conditions and once every five years for buildings that (completely or part of them) are subject to adverse factors;
  • upon termination of standard term of operation;
  • upon detection of defects and deformations;
  • after accidents and natural disasters;
  • when changing the purpose of construction;
  • by order of the supervisory authorities;
  • at the request of the owner.

What is the result of a technical survey?

As a result of the survey, the customer is issued an expert opinion, including:

  • survey results justifying the accepted category of the technical condition of the object;
  • assessment of the state of engineering systems, electrical networks and communication facilities, soundproofing properties of enclosing structures, noise of engineering equipment, vibrations and external noise, thermal performance of external enclosing structures;
  • survey results that substantiate the accepted estimates;
  • substantiation of the most probable causes of the appearance of defects and damages in structures, engineering systems, electrical networks and means of communication, reduction of sound insulation properties of enclosing structures, heat insulating properties of external enclosing structures (if any);
  • assignment for the design of measures for the restoration, strengthening or repair of structures, equipment, networks (if necessary).

Stages of technical inspection of buildings

Preparatory stage

At the preparatory stage, the experts examine all the available documentation: the project and technical documentation of the facility, including documentation on the operation and work performed. The task of the experts is to get the most complete picture of the construction of the object, the conditions of its operation and the possible "weak points" of the building. At the same stage, the terms of reference for the work is being prepared, and a program for further work is being drawn up.

The main task of the preliminary survey is to determine the general condition of the object of the survey, the collection of initial data for the development of technical specifications and the composition of further research.

Preliminary (visual) inspection of the building

At this stage, specialists inspect the building, check for visually noticeable defects, such as cracks in concrete walls and the foundation, damage to the foundation, are determined by external signs of the category of structural condition depending on the damage and defects present.

A category can be one of four:

  • regulatory technical condition;
  • healthy state;
  • limited working condition;
  • emergency condition.

The first two categories allow you to operate the building without restrictions and additional work. The assignment of the third obliges the owner to take measures to eliminate the identified problems. In the fourth category, the operation of the building is prohibited.

Based on a preliminary survey, a decision is made on the need for the next steps.

Detailed (instrumental) examination

The stage is the most important, as it includes instrumental examination of building structures and buildings. Through the use of equipment it becomes possible to obtain detailed information about the construction.

The physical characteristics of the materials of the structures in the laboratory are studied using special equipment and instruments, geological tests, measurement work (dimensioning, configuration, vertical positions and in terms of structures and structural elements), instrumental examination (measurement of deformations and deflections of supporting structures, soil deformations) are carried out. grounds and precipitation of foundations).

Inspection with the use of tools can be both continuous and selective. A complete survey involves the study of all elements of the structure. It is carried out in the absence of project documentation, if serious defects are detected. In a selective study, only individual elements of buildings that are in the worst condition are studied.

Summarizing carried out Survey

After the last stage of the study is completed, experts evaluate the overall technical condition of the object under study, draw up a technical report that contains all the data obtained and the results of the survey, develop recommendations for eliminating the problems identified, possible ways to strengthen the structure and operational safety due to increasing loads.

Conclusions on the technical survey consists of:

1. Text part containing information about the object.

  • its functionality,
  • The main parameters identified during the study,
  • the current state with the definition of the possibility of perception of additional deformations or other effects,
  • category of technical condition, survey data, defects found, results of complex research in the laboratory, calculation data,
  • all types of examinations of each structural element, starting with the foundation and ending with a roof.

In conclusion, conclusions are included, as well as a set of recommendations on measures that can eliminate the detected damage, ensure the safety of operation and other work at the facility.

2. Graphic materials, consisting of all the necessary applications in graphic form.
