Service " Technical audit of engineering networks"It is a complex of diagnostic measures that are necessary to fix information on possible violations in engineering equipment. Based on this data, a plan for reconstruction or replacement of certain parts of the engineering system is created. In the long run, this measure allows you to prevent accidents and breakage.

An inspection of engineering networks includes 4 types of work:

Visual inspection and assessment of the technical condition of engineering networks
This block of work includes a visual inspection of the structural features of the building and its engineering systems. At this stage, experts detect damage, on the basis of which a defective statement is formed. Also interview staff and representatives of contractors to get the most objective data.
Checking the compliance of actual qualitative and quantitative parameters recommended for this class and building type
The second stage of work is to conduct a series of measurements to determine key technical parameters, the logging of survey results. The data obtained is compared with permissible, disorders are detected.
What parameters are checked for compliance with the standards?
- air temperature indoors in summer - 23-25 \u200b\u200b° C, in winter - 22-24 ° C;
- air humidity 40-60%;
- circulation of air seats 60 m 3 / h per 10 m2;
- air exchange in the workplace - 0.13-0.25 m / s;
- illumination - 300-500 suites;
- noise level should not exceed 55 dB.
In the course audit The following instrumental measuring instruments are used:
- The thermal imager - helps to identify the defects of the heat shield of the building.
- Current electrical ticks - measures current strength.
- Multimeter - measures stresses, resistance, current forces.
- Schometer - measures the noise level.
- Pyrometer - measures the surface temperature.

Preparation of a detailed report with the results of an audit of engineering systems

At the final stage, a report is drawn up with conclusions on the fact of a comprehensive surveys of engineering networks.
The report consists of the following documents:
- conclusion with the results of inspection and evaluation of the technical condition of each of the engineering systems separately;
- defective statement with photos and detailed descriptions of faults, with terms and estimated cost of elimination;
- Conclusion with the results of the measurements of the parameters of premises with the allocation of non-compliance with admissible standards;
- report reconciliation for the presence / absence of mandatory executive and technical documentation at the facility. Recommendations on the quality of operational journals;
- definition of compliance or non-compliance with engineering systems by fire safety, electrical safety, sanitary and epidemiological and environmental standards;
- conclusion About the work of accounting devices and recommendations for reducing costs for resource consumption.

To date, engineering networks are an important part of not only a separate building, but also a large system, with which the facilities are provided with the necessary resources. Their status is paid to special attention, because it is very important to maintain the system's performance and timely prevent possible breakdowns.

Survey of engineering systems and networks is a set of activities carried out to assess the current state and functionality of engineering systems, detecting defects and faults, determining the possibility of connecting additional equipment, determining the compliance of engineering systems of project and regulatory documentation.

As a rule, technical inspection of engineering networks occurs during their operation. Wear is an integral part of the use of the system, and it occurs under the action of natural external factors. On average, networks can serve for 10-20 years without repair and additional work, and the service life depends on external conditions, timeliness and quality of the repairs.

Stages of the inspection of engineering networks:

Careful inspection of the system to obtain the necessary parameters.

Study of the data and project documentation. Specialists browse work plans and reveal possible deviations during networks.

It is checked with compliance with regulations, because the service life depends on all of these parameters.

If you are in doubt about the contractual organization provided by the contracting organization, experts will be able to determine the cost of the system of the system and prevent overpricing.

Technical inspection of engineering systems is carried out almost for all types of networks, depending on the requests of the customer himself. It can be carried out both for all elements and for individual.

10. Executive Schemes - Plans with Engineering Systems

What can be required by our specialists in the course of work?

Project documentation.

Drawings of the system used to prepare work and during their conduct.

Information on repairs, spectrum of restoration work.

Other documents providing information about the object of examination.

Thus, this examination is often carried out not only with accidents or breakdowns. Our specialists recommend periodically inspection of engineering systems, determining the current state and the need to repair individual elements. Timely detected faults to eliminate much easier than their future consequences and serious breakdowns. An assessment may be required in the process of trial.

Service cost:

The minimum cost of the examination of engineering networks and systems of 20,000 rubles.

Today, engineering networks are an important part of not only a separate building, but also a large system, with which the facilities are carried out by the necessary resources. Their status is paid to special attention, because it is very important to maintain the system's performance and timely prevent possible breakdowns.
As a rule, technical inspection of engineering networks occurs during their operation. Wear is an integral part of the use of the system, it occurs under the action of natural external factors. On average, networks can serve for 10-20 years without repair and additional work, and the service life depends on external conditions, timeliness and quality of the repairs.

Why is the intervention of specialists in this question? Even experienced customers do not have a sufficient spectrum of knowledge to accurately determine the state of the system. A large number of additional funds will be required, many associated work. Naturally, exclusively professionals with extensive experience should be engaged. Only experts will be able to accurately determine all the necessary parameters, to analyze the data obtained and submit a conclusion on the results of the research conducted.

For what cases is necessary analysis

There are a number of factors under which an inspection of engineering networks is carried out. It all depends only on the needs of the customer, it can order any expertise for these systems.

In some cases, customers need primary network analysis after it laying. There are often cases when the company doubts his artist and wants to check whether the work of the contractor was performed correctly. For this, the following operations are carried out:

Careful inspection of the system to obtain the necessary parameters.
Study of the data and project documentation. Specialists browse work plans and reveal possible deviations during networks.
It is checked with compliance with regulations, because the service life depends on all of these parameters.
If you are in doubt about the contractual organization provided by the contracting organization, experts will be able to determine the cost of the system of the system and prevent overpricing.

There are other cases when the system surveys may be required. One of the options is to reconstruct and you need to check the current state to determine the possibility of such work.

Often the survey is carried out before the overhaul of the system. The main task of specialists is to evaluate the wear and current disorders to give an answer to the question of the need for large-scale equipment recovery.

Another factor is a change of tenant or the transfer of networks from one balance to another. In this case, it is important to determine which state is the system at the moment and how soon repair work will be required for it, including a large-scale update. Additionally, the current state of the systems during transmission is recorded, and official documents are submitted to you with the conclusion of specialists.

If frequent breakdowns occur, then this is another reason for inviting specialists to inspect. Only professionals will be able to check the entire area, determine the level of wear and find possible disorders that cause frequent problems of the system and its failure.

Networks for which inspection

Technical inspection of engineering systems is carried out almost for all types of networks, depending on the requests of the customer himself. It can be carried out both completely for all elements and for individual elements.

Which parts of the system may be inspected:

Trunks to remove garbage, their current state, the possibility of operation and repair, compliance with the original project.
Air ducts are very often inspected. Experts inspect all ventilation systems indoors and check their condition.
Inspection can be carried out for drainage. The task of specialists not only check the main parameters, but also to create a scheme on which tightness and possible gaps are indicated.
The control of the engineering equipment itself is important. It can tritely obscure or wear out in the process of use, and the task of specialists is to determine the possibility for further operation.
Much attention is paid to electrical networks. The main task is to check all components, starting with shields, ending with lighting. Additionally, a plan is drawn up, it indicates the location of individual elements, layout, etc.
A technical inspection of the heating system is carried out in order to determine its indicators, the correctness of the arrangement, compliance with the norms and the possibility of further operation.

Recall that the survey is often carried out not only during transmission to the balance or with frequent breakdowns. Specialists recommend inspection of systems from time to time, determining the current state and the need to repair individual elements. Timely detected faults to eliminate much easier than their future consequences and serious breakdowns.

The assessment may be required to you in the process of trial. If you have an argument with another organization, which cannot be solved by negotiation, then you need to attract the experts to this issue. They will fulfill all the necessary inspection operations and will submit their own conclusion with the answer to all the questions.

Experts make an independent opinion during their work. They have no task in defending the interests of one of the parties, and this can be called the basic value of the help of professionals. They provide an objective solution that can be used in proceedings.

About process

Technical examination of equipment and networks is carried out taking into account two defining factors:

Much attention is paid to physical wear, it is he becomes the main problem during the operation of systems. This factor depends on the overall state, it is determined by current indicators, the number of repair and restoration work.
No less important indicator - moral wear. When it is determined, possible disorders are taken into account during the arrangement, which affect the general characteristics of the system. Another parameter is an obsolescence of equipment, as a result of which it no longer complies with modern requirements.

How is the survey process itself:

First you appeal to the company, determine the scope of expert work that you needed.
Experts prepare a service contract and signing it.
Experts leave for a specific object, carry out the necessary examination and perform the range of required measurements. At the disposal of specialists there is a modern technique for full-fledged work.
Further, employees analyze the results, compare them with the project of work that are valid and begin to prepare the report.
In conclusion, they prescribe found deviations and violations, give a general assessment of the state of the system and respond to other issues delivered by the customer.

What may be required to specialists in the process of work:

Project documentation.
Drawings of the system used to prepare work and during their conduct.
Information on repairs, spectrum of restoration work.
Other documents providing information about the object of examination.

The inspection of engineering networks of the building is carried out with a comprehensive assessment of the technical condition of buildings.

During the inspection of engineering networks, defects, damage and malfunction of the system elements are detected. The technical condition of the elements of the system is produced by the "Provision on the organization and conduct of reconstruction, repair and maintenance of buildings, objects of communal and socio-cultural purposes". Physical wear is determined by VNN 53-86 (P). If in the survey process it was found that the elements of the system and repair of networks were replaced, then the physical wear is determined by the tables of the physical wear assessment tables and the timelines of the service life of the elements, as a weighted average. When determining wear on the schedules of service time and determination of wear on the tables of physical wear, for the final result is taken more from the values. According to the results of a technical inspection of the system and assessment of physical wear, a decision is made to further exploit the system or overhaul of engineering systems of the building.

In the process of exploitation of an apartment building There are cases of the bay of residential premises when accidents in engineering networks of the building occurring for the following reasons:

Damage to the shut-off valves, due to its low-quality installation.
The use of poor-quality shut-off valves that does not have certificates and (or) passports with the manufacturer's guarantee.
High physical wear of pipelines of DHW, HPW, heating, sewage.
The presence of defects in the overall system (disruption of sealing in connections of sewage risers, inner drain, etc.).

When conducting examination The causes of the system's accident is determined by the place of the accident, the technical condition of the shut-off reinforcement and system pipelines is estimated. In the destruction of the shut-off reinforcement, an examination of parts of the reinforcement in the laboratory is made, in order to establish the quality of the material, the microscope is inspected a section at the destroyer.

Cases arise accidents with the destruction of reinforcement, damage to pipelines, as well as emergence of accidents when commissioning the system after interrupting the operation of the system (seasonal inclusion of hot water, heating). After the emergency service accident is eliminated by employees of the operating organization, the act of its reasons is drawn up, indicating the place of the bay, the area of \u200b\u200bdamage to the finishing coatings.

When conducting examination The states of the residential premises for recovery after the bay, a defective statement is drawn up, indicating:

locations of defects,
name and volumes of defects,
cause of defects
photo scattering of defects,
the parameters of the humidity of building structures and the finishing coating are performed, since The device of the new finishing coating must be performed only after the normalization of the moisture content of the base to the normative value,
estimated replacement repair is compiled.
