Preliminary (visual) inspection of buildings. Visual inspection and examination of buildings and structures Visual technical inspection of buildings and structures

Survey building structures, including buildings, is carried out in order to determine the actual values ​​characterizing, at this stage, the operational state of buildings. The need for such a survey is associated with determining the possibility of continuing operation, without making any changes to the structure, or with recommendations for the restoration or strengthening of the existing structure.

In modern construction, a mandatory justification for a visual inspection is required

Inspection of building structures, including buildings, is carried out in order to determine the actual values ​​characterizing, at this stage, the operational state of buildings. The need for such a survey is associated with determining the possibility of continuing operation, without making any changes to the structure, or with recommendations for the restoration or strengthening of the existing structure. The main directions that are guided during the preliminary survey are:

Identification of possible defects and damage arising after exposure to man-made (fires, soil subsidence) or natural (flooding) influences on the building structure.

Increased loads associated with redevelopment or an increase in the number of floors.

Proposed or ongoing reconstruction.

Renewal construction works at the facility, after long-term conservation.

Survey process

Preliminary (visual) inspection of buildings provides for a set of works related to the inspection appearance... In this case, ordinary measuring instruments (tape measures, probes) and devices are used that allow a detailed examination of the appearance of buildings (binoculars, a camera, a level). The survey is carried out by qualified specialists. In this case, the following are subject to visual inspection:

Foundations.

Overlapping.

Pillars, columns, walls.

Beams, trusses.

Connecting elements and stiffening structures.

All available for inspection, joints, connections, nodes.

All found defective areas are subject to careful measurement, description, photographing, followed by drawing up diagrams of their location. A statement is drawn up, which indicates the technical parameters of the damage. A preliminary (visual) inspection of buildings is also carried out to identify deformation of the entire building structure (roll, deflections, faults) and its individual structures. A reconnaissance survey of the facility is underway. Based on the obtained results of the survey, a preliminary conclusion of the technical condition of the inspected object is drawn up. Based on this conclusion, a decision is made to eliminate the existing shortcomings, without additional research. Or, a decision is made on the need for a more thorough instrumental examination.

The cost of the work carried out directly depends on the technical condition of the object itself, its location, the purpose of the survey of buildings. You can order such work in companies licensed to conduct such research. Price for given view the work is quite high, but the estimate is made taking into account the full cycle of the survey, which includes geodetic survey of the object. Upon completion of the work, the customer is issued an act of technical inspection of the object.

Contacting qualified specialists will protect your project for many years and will allow you to implement any project. We recommend that you turn your attention to the company leader in the field of geodetic research - LLC "Geologist". The fact that specialists work in many regions and cities of our country is very favorable: Moscow, St. Petersburg, Moscow region, Yaroslavl region, Tula region, Tver region, Kaluga region, Ryazan region, Bryansk region, Vladimir region, Nizhny Novgorod region, Voronezh region, Kursk region, Tambov region, Belgorod region, Penza region, Krasnodar region, Leningrad region, Pskov region.

Building survey- this is a specific list of operations, the purpose of which is to check the condition and defects of both the buildings themselves and any of its structural elements.

There are several main objectives of the survey:

1. Checking and research before putting buildings into operation;

The main task is to check the compliance of the constructed building with the design documentation, as well as to identify violations.

1. Inspection and research of buildings that have already been built.

Determination of the deterioration of the building, the possible load-bearing structure of the building elements, the removal of parameters for the reconstruction of the building. Scheduled and unscheduled inspections.

1. Various laboratory tests of structural elements;

There are basic requirements for buildings and structures that cannot be violated:

1. All buildings and structures must be strong and stable.
2. Cracks and damages lagging behind the building.

All other deviations from the normal state of objects should be investigated by trained engineers with experience in the relevant objects, with specialized equipment available.

Any survey consists of several elements:

1. Primary. Study of design documentation, familiarization with the repair work carried out.

In this case, it is possible to determine the weak areas of the design schemes, as well as the places of maximum load and the theoretical degree of deterioration.

1. Visual inspection. Engineer examines the conformity of the object working documentation, searches for defects, draws up a plan for a more detailed examination. All surveys are carried out using non-destructive methods.

Important. Non-destructive methods - any types of surveys that do not require the direct disabling of operating facilities, without physical sampling of materials.

The visual examination includes:

• Real estate measurements and subsequent manufacturing.
• Drawing up a list of defects with photographs.
• Assessment of the reliability of building elements.

At the end of the visual examination, the customer is provided with

• List of defects, with a description of their nature, location on the diagrams;
• Photo fixation with the class and characteristics of defects;
• Description of possible deformations of the building or its individual elements (deflections, rolls, bends, distortions, faults, etc.);
• Identification of emergency areas;
• Renovation and diagrams of sections of the building;
• Definition of load-bearing walls and structures with their location in the drawings;
• Preliminary analysis of the state of the supporting structures, engineering networks;
• Recommendations, estimates for eliminating the identified deviations;

1. Complete analysis with testing of structural elements and development possible ways solving the tasks.

Definition design features parts of the building, assessment of the technical condition of the load-bearing and enclosing structures of the building to calculate the loads on the floor floors. Structural elements are subject to technical inspection: foundations, floors, walls.
