Technical inspection of engineering networks. A high-quality inspection of networks and structures will avoid many troubles

In the case when a property is purchased, as well as during its reconstruction, a conclusion on the technical condition of the building and communications, drawn up based on the results of the work, during which the inspection of utility networks and building structures, becomes one of the main documents that allows us to assess the possibility of stable operation of a property 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 wear and tear of the networks, and if the operation services do not constantly monitor their condition, then the occurrence of emergency situation leading to material damage. Equally important is a comprehensive examination of structures and networks at the stage of assessing the cost of the acquired object. If external communications and internal networks are in good condition and are suitable for use for the purpose planned by the new owner, then the value of the property has the same value. If, after the purchase, it is necessary to relocate or repair networks, or reconstruct the life support systems of the building, then these costs should be taken into account when determining the final cost of the purchase. For several years now, the conclusions made by the Expertsystem company based on the results of surveys have made it possible to determine the optimal cost of the object for both parties.

In the case of reconstruction of a building, 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 an inspection of engineering systems and building structures was carried out, compiled in the form of a report, becomes a document on the basis of which the examination bodies evaluate the correctness of the decisions included in the project, their compliance with the requirements of current standards and issue an opinion on the suitability of the documentation to implementation. And the expert’s conclusion, in turn, is necessary to obtain permission for the construction and reconstruction of a real estate property. It should be noted here that reports on technical examinations performed by the Expertsystem company are always accepted by the examination bodies without any comments.

Inspection of utility networks is the key to the operability of the building’s life support systems

To assess the condition of the property, a technical inspection of the building's utility networks and building structures is carried out, which is specified when the customer draws up the work assignment and is taken into account by the contractor when developing the inspection program. When determining the operability of the building's engineering networks, the Expertsystem company performs the following work:

• visual and instrumental inspection of water and heat supply pipelines, sewerage, steam and gas pipelines providing the property with these types of energy resources. The 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 where the network enters the building;
• inspection of the water supply system, when checking the compliance of pipe diameters executive documentation, presence and condition of valves, safety of well structures. When inspecting internal cold water supply networks, the condition of the pipework, the operability of shut-off valves, and the presence of flow meters are recorded. The technical report 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;
• sewer inspection, during which the condition of inspection, control and differential wells, trays is determined, the diameter and material of the pipes is recorded, and the presence or absence of counterslopes between the wells is checked. Internal sewerage checked 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, the reliability of ventilation equipment, and the 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 checked;
• inspection of electrical networks, when the operability of the facility’s power supply line from transformer substations where the cables are connected (if there are two or more inputs) to the input and 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 and lighting panels, and the safety of terminal devices are determined. The presence or absence of a ground loop is also noted.

A full inspection of engineering systems is quite labor-intensive work and requires highly qualified performers. But the results and recommendations obtained will make it possible to specifically determine the amount of costs required to bring the utility networks of a property to a condition that guarantees safe operation buildings and the absence of claims from supervisory authorities. This is exactly the kind of work offered by the Expertsystem company, which employs specialists high level using modern instruments and software during examinations.

Inspection of building structures - checking the reliability of the building

Simultaneously with determining the condition of utility networks, an inspection of the structures of a building or structure is carried out, based on the results of which a conclusion is drawn about the condition of individual structural elements, and recommendations are given on ways to eliminate identified deviations from standard indicators. Depending on the scope of work provided for by the task, the following is performed:

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

Who can you trust to conduct examinations?

A comprehensive inspection of engineering systems and building structures is a very complex and responsible job, when an error can lead to quite serious consequences. Therefore, enterprises providing services of this profile must have the approval of a self-regulatory organization, confirming the presence of qualified personnel, as well as the necessary material base. The Expertsystem company also has such permission.

The Expertsystem company has been carrying out inspections of buildings and structures in Moscow and the Moscow region for several years now, and each time the reports completed by the company’s specialists have been received positive characteristics expert bodies, and the assessment of the condition of the property became the basis for determining a fair price for a building or structure.
