Examination of engineering communications is one of the most demanded types of building research. According to its results, the conformity of the object is revealed:

Safety requirements;
State standards and technical regulations;
Organization standards;
Town planning plan;
Estimated regulatory framework.

Regular examination of engineering systems can significantly reduce the risk of accidents, leaks, and, as a result, minimize monetary costs, since the cost of eliminating the consequences of gulfs, fires and other emergencies on engineering systems is many times higher than the cost of surveys and maintenance.

The cost of the examination of engineering communications depends on the area of the building, the type of systems, the amount of work of the same type.

Expertise should be trusted only by specialized organizations.

Expertise of engineering communications is a complex service that is often required in the construction, operation of buildings or structures, as well as in the implementation of commercial transactions with real estate. The cost and possibilities of normal operation of the facility directly depend on the operability of engineering communications.

Inspection of engineering communications requires the involvement of qualified experts who will conduct all the necessary tests and calculations, make an opinion and provide recommendations for troubleshooting. A properly executed expert opinion, if necessary, can be presented in court.

Carrying out inspection - 2 working days, analysis of the results obtained and available documents examination and issuance of an expert opinion - from 3 to 21 working days from the date of payment for services. The specific terms of work are determined depending on the specific facility and the number and complexity of the systems available at the facility.

You can examine as separate systems and all systems of the object.

The cost of inspection of engineering systems

In the initial assessment of the cost of the survey of engineering systems, the base prices are multiplied by correction factors that depend on: the type of engineering system; the volume of the building; the number of works of the same type. The final cost can be influenced by technical data, which revealed the need for the use of expensive means and methods of examination.

Where can a survey of engineering systems be ordered?

Expertise of engineering systems is necessary before reconstruction or overhaul buildings. This work can only be entrusted to experts whose qualifications are documented. Specialists will determine the suitability of engineering systems for further use, determine the need for their improvement or repair, and provide written recommendations.

Instrumental research of engineering systems is an important part of the experts' work. It helps to identify damage and defects, avoid accidents, restore the required temperature and humidity in the building, and optimize energy consumption.

EXPERT OPINION: The full and effective functioning of engineering systems requires a planned, and in some cases - an unscheduled survey. The success of possible judicial or extrajudicial disputes with contractors, commissioning and commissioning of networks, the prevention of failures in the operation of engineering systems, the accuracy of calculating estimates with repair work... Due to the specifics and complexity of the survey of engineering systems, you should always contact only organizations that have experience in carrying out complex work.

In the case when a real estate object is purchased, as well as during its reconstruction, the conclusion on the technical condition of the building and communications, drawn up based on the results of the work, during which the survey of engineering networks and building structures was carried out, becomes one of the main documents that allow assessing the possibility of stable operation of the object real estate in new conditions.

Are examinations really necessary?

Any building requires periodic inspection of communications, both external and internal. The need to carry out such work is caused by the deterioration of the networks, and if the maintenance services do not constantly monitor their condition, then an emergency situation may occur, leading to material damage. Equally important is a comprehensive survey of structures and networks at the stage of assessing the cost of the purchased object. If the external communications and internal networks are in good condition and suitable for use for the purpose planned by the new owner, then the value of the property has one value. If, after the purchase, you have to shift or repair the networks, reconstruct the building's life support systems, then these costs should be taken into account when determining the final cost of the purchase. It is not the first year that the conclusions made by the "ExpertSystem" company based on the results of surveys make it possible to determine the cost of the object that is optimal for both parties.

In the event of a building reconstruction, inspection of building structures and networks is mandatory. The conclusion about this work is one of the main documents in the list of initial data for design. In addition, the results of the work, during which the inspection of engineering systems and building structures was carried out, drawn up in the form of a report, becomes a document on the basis of which the examination bodies evaluate the correctness of the decisions laid down in the project, on their compliance with the requirements of the current standards and issue a conclusion on the suitability of the documentation. to implementation. And the expert opinion, in turn, is necessary to obtain a permit for the construction and reconstruction of a real estate object. It should be noted here that reports on technical surveys carried out by ExpertSystem are always accepted by the examination bodies without any comments.

Inspection of engineering networks is a guarantee of the operability of the building's life support systems

To assess the condition of the real estate object, a technical survey of the engineering networks of the building and building structures is carried out, which is negotiated when the customer draws up the work assignment and is taken into account by the contractor when developing the survey program. When determining the operability of the engineering networks of the building, the company "Ekspertsistem" performs the following works:

visual and instrumental inspection of water and heat supply pipelines, sewerage, steam and gas pipelines that provide the property with these types of energy resources. Inspection of external networks is carried out from the point of insertion into the backbone networks specified in the act of dividing the boundaries between the energy supplier and the owner of the property, to the point of entry of the network into the building;
inspection of the water supply system, when the compliance of the pipe diameters with the executive documentation is checked, the presence and condition of valves, the safety of well structures. When inspecting the internal networks of cold water supply, the state of the piping, the operability of the shut-off valves, and the presence of flow meters are recorded. The technical conclusion must indicate the presence, location and serviceability of fire hydrants, as well as the completeness of fire hydrants inside the building and the operability of the fire water supply system;
inspection of the sewage system, during which the state of inspection, control and drop wells, trays is determined, the diameter and material of the pipes is fixed, the presence or absence of counter-slopes between the wells is checked. Internal sewerage is checked in order to determine the degree of sealing of pipe joints and the safety of wastewater receivers;
inspection of ventilation and air conditioning systems, which determines the degree of wear and contamination of air ducts, reliability of ventilation equipment, reliability of thermal insulation of air intake points supply ventilation, safety of louvered grilles and deflectors. The safety and operability of the fire smoke removal system is being checked;
inspection of electrical networks, when the operability of the power supply line of the facility is checked from the transformer substations where the cables are connected (if there are two or more inputs) to the input distribution devices inside the building, the characteristics of the cable are recorded. Inside the building, the brands of wires and cables, the brands and serviceability of power shields and lighting shields, the safety of terminal devices are determined. The presence or absence of a ground loop is also noted.

A full-fledged survey of engineering systems is a rather laborious work and requires high qualifications of performers. But the results and recommendations obtained will allow us to specifically determine the amount of costs required to bring the engineering networks of the real estate object into a condition that guarantees the safe operation of the building and the absence of claims from supervisory authorities. This is the kind of work that ExpertSystem offers, which employs high-level specialists who use modern instruments and software for examinations.

Inspection of building structures - checking the reliability of a building

Simultaneously with the determination of the state of engineering networks, an examination of the structures of a building or structure is carried out, based on the results of which a conclusion is made about the state of individual structural elements, and recommendations are given on how to eliminate the identified deviations from the normative indicators. Depending on the scope of work stipulated by the assignment, the following is performed:

examination of foundations with the determination of the depth of their foundation, the size of the sole, and, if necessary, pits are opened, and the condition of the base soils is checked. Most often, at the same time as the foundations, the basement is examined, when the safety of the walls is recorded, the tightness of the entry points of engineering communications into the building, the construction and safety of the floors;
examination of columns, girders, beams, floor slabs, during which their actual dimensions are measured, if necessary, the reinforcement of structures and the strength of concrete are determined by non-destructive methods, on the basis of which a conclusion is made about the possibility of transferring additional load to the frame elements (during the reconstruction of the building) and the suitability of the elements frame for further use. Measurements are also made for the support values of structural elements in order to conclude with recommendations for their increase;
obligatory instrumental examination metal structures frame of the building. During these works, the absence of damage to the elements is checked, deflections are measured, the state of anti-corrosion protection is determined. The supporting units of the structures are inspected, while the presence, number and diameter of bolts, nuts and washers or the length and legs of welds are recorded. Based on the results of the stage of work, when the steel structures were inspected, the report proposes measures to correct the identified deficiencies, including the necessary reinforcement sketches. The results of visual and instrumental examinations are taken into account when developing design solutions for load-bearing steel structures of reconstructed buildings;
inspection of walls, when the thickness and material of the fence is checked, if necessary, samples are taken, according to which the thermal characteristics of the structures and their compliance with the requirements of energy saving are determined. The quality of the panel joints and the condition of the sealing materials are checked.
roof inspection civil buildings with attics, during which the condition of the rafter structures and their places of support, the integrity and presence of fastening elements are examined roofing materials with a pitched roof, the safety of gutters and pipes, the quality of thermal insulation of the attic floor. In case of flat or low-slope roofing, the inspection of the roof consists in assessing the condition of the roll carpet, as well as in determining the physical and mechanical characteristics of the existing insulation. This stage also serves as the basis for the development of measures to improve the energy efficiency of the building.

Who can be trusted to conduct surveys

A comprehensive survey of engineering systems and building structures is a very difficult and responsible job, when an error can entail quite serious consequences. Therefore, enterprises providing services of such a profile must necessarily have the admission of a self-regulatory organization, confirming the availability of qualified personnel, as well as the necessary material base. The company "Ekspertsistem" also has such an admission.

For more than one year, ExpertSystem has been conducting surveys of buildings and structures in Moscow and the Moscow Region, and each time the reports carried out by the company's specialists received positive characteristics from the expert bodies, and the assessment of the condition of the property became the basis for determining the fair price for a building or structure.
