Technical conclusion on the condition of the sewer collector. Inspection of the health of engineering systems

Service " Technical audit of engineering networks» is a set of diagnostic measures that are necessary to record information about possible violations in the operation of engineering equipment. Based on these data, a plan is created for the reconstruction or replacement of certain parts of the engineering system. In the long term, this measure helps prevent accidents and breakdowns.

Inspection of engineering networks includes 4 types of work:

  1. Visual inspection and assessment of the technical condition of engineering networks

    This block of work includes a visual inspection design features buildings and his engineering systems. At this stage, specialists identify damage, on the basis of which a defective statement is formed. They also interview personnel and representatives of contractors in order to obtain the most objective data.

  2. Verification of compliance of the actual qualitative and quantitative parameters with those recommended for a given class and type of building

    The second stage of work - a series of measurements to determine the key technical parameters, recording the results of the survey. The received data are compared with admissible ones, violations are revealed.

    What parameters are checked for compliance with the standards?

    • indoor air temperature in summer - 23–25°С, in winter - 22–24°С;
    • air humidity 40–60%;
    • circulation of air masses 60 m 3 / h per 10 m2;
    • air exchange at the workplace - 0.13–0.25 m / s;
    • illumination - 300–500 lux;
    • noise level should not exceed 55 dB.

    During audit the following measurement tools are used:

    • Thermal imager - helps to identify defects in the thermal protection of the building.
    • Current electric pincers - measures current strength.
    • Multimeter - measures voltage, resistance, current.
    • Noise meter - measures the noise level.
    • Pyrometer - measures surface temperature.
    • Anemometer - measures the speed of the air flow in closed systems and in open areas (measuring the speed of the air flow inside the air ducts).
    • PH-meter - measures the level of hydrogen ions in the system.
    • Luxmeter - measures the level of lighting in the workplace.
    • Device for measuring CO2, temperature and air humidity.

  3. Analysis / verification of current technical documentation

    The third block of works includes:

    • verification of the availability of correctly completed documentation (in accordance with the register of documents that regulates the activities operating organizations);
    • checking the availability of documentation for equipment (technical passports);
    • checking compliance with safety regulations, as well as the availability of logs and the correctness of their completion;
    • analysis of concluded contracts with resource providers;
    • diagnostics of metering devices.

  4. Preparation of a detailed report with the results of the audit of engineering systems

    At the final stage, a report is drawn up with conclusions on the fact of the complex surveys of engineering networks.

    The report consists of the following documents:

    • conclusion with the results of the inspection and assessment of the technical condition of each of the engineering systems separately;
    • a defective statement with photographs and a detailed description of the malfunctions, with the timing and estimated cost of elimination;
    • Conclusion with the results of the measurements of the parameters of the premises, highlighting the discrepancy acceptable standards;

    • determination of compliance or non-compliance of engineering systems with fire safety, electrical safety, sanitary-epidemiological and environmental standards;
    • conclusion on the operation of metering devices and recommendations for reducing the cost of resource consumption.

In what cases is a survey of engineering networks of buildings carried out? A list of primary documentation for starting a survey of communications, conducting an examination and drawing up a technical opinion.

A comprehensive analysis of buildings requires a survey of external engineering networks and internal systems communications in order to determine the technical condition of the equipment and its elements. The expert evaluation procedure is obligatory when it is necessary to substantiate the decision on the possibility of complete or partial reconstruction, overhaul and modernization of the object under study.

The essence of the survey is to study the functional characteristics, their compliance with current technical standards and design and executive documentation of water pipes, sewerage, ventilation shafts, heating systems, gas supply and other engineering equipment. Based on the data obtained, specialists will be able to provide recommendations on the operation or dismantling of old ones, design new engineering networks and systems, determine the possibility of connecting additional equipment and calculate the amount of work.

Technical documentation to start a communications survey

According to regulations, before starting work, the examiners should familiarize themselves with the current technical documentation of the engineering networks of the building.



Drawing up a work plan, setting tasks and expertise to assess the technical condition is carried out for the following objects:

  • multi-storey residential buildings and cottage settlements;
  • public institutions (hospitals, clinics, kindergartens, schools, educational establishments);
  • office buildings (including the surrounding area);
  • industrial facilities, warehouse and production facilities;
  • technical structures and agricultural buildings;
  • sports centers, stadiums, ice palaces;
  • construction of urban infrastructure.

For the purpose of primary research, survey engineers study drawings (executive and working), acceptance and testing certificates, technical passports of the equipment used in engineering networks, certificates for operation. All norms, work regulations and requirements are set out in GOST R 53778-2010.

Scope of work on the study of engineering networks

In each individual case, not only the analysis of technical documentation is carried out, but also instrumental diagnostics, as well as a visual inspection of all important components in order to search for defects and worn parts. In addition, surveyors Company "Promterra", if necessary, search for hidden underground utilities using special equipment.



The performers face many functional tasks, since in the process it is necessary to examine the internal and external engineering networks, to assess the technical condition:

  • hot and cold water supply;
  • heating and heat supply;
  • internal ventilation systems;
  • sewerage and waste disposal;
  • gas supply systems;
  • drains and heating systems;
  • external electrical networks;
  • engineering equipment.

Equipment that is physically worn out and obsolete must be replaced. To confirm, experts perform verification calculations. The survey allows you to assess the scope of work, including financial costs. If necessary, instrumental measurements of places and elements can be selectively assigned. During the examination, it is necessary to take clear photographs of the detected damage.

Technical conclusion and deadlines for the examination

How much time is needed for a qualitative survey of the foundation and the underground part of the building with the presence of utility networks depends on several factors: the complexity of the object under study and its size, customer requirements and the need for detailed data, technical characteristics of communications, their density, construction features. The terms and volumes of expert work are set by the executors on an individual basis.




Upon completion of the examination of all external and internal communication systems, a technical opinion is drawn up. It displays the results of research, brief operating conditions of engineering networks, analysis of the object in accordance with the requirements of regulatory documents and the alleged causes of the detected defects. One of the important sections of the conclusion is the rationale for design decisions that are required for the repair or modernization of water pipes, heating networks, sewerage, ventilation and electrical networks of a building or territory. At the end of the document, SRO certificates must be attached.

Inspection of engineering systems: tasks, stages and cost of the procedure

Expertise engineering communications is one of the most popular types of building studies. According to its results, the correspondence of the object is revealed:

  • security requirements;
  • State standards and technical regulations;
  • Organizational standards;
  • town planning plan;
  • Estimate-normative base.

Regular examination of engineering systems can significantly reduce the risk of accidents, leaks, and, as a result, minimize cash costs, since the cost of eliminating the consequences of floods, 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.

Examination should be trusted only to 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 commercial real estate transactions. The cost and possibilities of normal operation of the facility directly depend on the efficiency of engineering communications.

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

Stages of inspection of engineering communications of buildings:

Analysis of technical documentation. Allows you to determine the initial data: the timing of construction and operation, the location of communications and terminal equipment, the results of previous examinations. Working and as-built drawings, acceptance and test certificates, passports and certificates for equipment, repair logs are subject to analysis.

Visual inspection. At this stage, an initial inspection of the systems is carried out to determine obvious malfunctions and the need to use special equipment.

Instrumental examination. The stage of instrumental examination provides numerical data for the analysis of system performance. It includes the measurement of linear dimensions, the identification of deformations, defects and damage, the collection of data on loads and / or costs.

Result analysis in. Based on the analysis, the degree and causes of physical deterioration of engineering communications are revealed, conclusions are drawn about the technical feasibility of using existing systems.

Drawing up a list of defects. The goal of this step is to create full list damaged and/or worn and replaceable parts of engineering systems.

Holding inspection - 2 working days, analysis of the results and available documents examination and issuance of an expert opinion - from 3 to 21 business days from the date of payment for services. 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 both individual systems and all systems of the object.

The cost of surveying engineering systems

During the initial assessment of the cost of surveying engineering systems, base prices are multiplied by correction factors that depend on: type of engineering system; volume of the building; number of similar jobs. The final cost may be affected by technical data that has revealed the need for expensive means and methods of examination.

Where can I order an inspection of engineering systems?

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

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

EXPERTS OPINION: The full and effective functioning of engineering systems requires a scheduled, and in some cases, an unscheduled survey. From the quality and timing of its implementation, the correctness of registration required documents the success of possible litigation or out-of-court disputes with contractors, commissioning and commissioning of networks, prevention of failures in the operation of engineering systems, and the accuracy of calculating estimates during repair work also depend. Due to the specifics and complexity of surveying engineering systems, you should always contact only organizations with experience in conducting complex work.

In the case when a real estate object is acquired, 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 an inspection 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 the new conditions.

Are surveys really necessary?

Any building requires a periodic survey of communications, both external and internal. The need for such work is caused by the deterioration of 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 external communications and internal networks are in good condition and fit for use as intended by the new owner, then the value of the property has one value. If, after the purchase, it is necessary to shift or repair networks, reconstruct the life support systems of the building, 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 optimal cost of the object for both parties.

In the case of a building reconstruction, a survey 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 survey of engineering systems and building structures was carried out, drawn up in the form of a report, become 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 current standards and issue a conclusion on the suitability of the documentation to implementation. And the conclusion of the examination, in turn, is necessary to obtain a permit for the construction and reconstruction of a property. It should be noted here that reports on technical surveys performed by Expertsystem are always accepted by the examination bodies without comment.

Inspection of engineering networks is the key to the operability of building life support systems

To assess the condition of the property, a technical examination of the engineering networks of the building and building structures is carried out, which is stipulated when the customer draws up the assignment for work and is taken into account by the contractor when developing the survey program. When determining the operability of engineering networks of a building, Expertsystem performs the following work:

  • visual and instrumental inspection of pipelines for water and heat supply, sewerage, steam and gas pipelines that provide the property with these types of energy resources. Examination of external networks is carried out from the point of insertion into the main 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 the compliance of the pipe diameters with the executive documentation, the presence and condition of the valves, the safety of the well structures are checked. When examining internal networks of cold water supply, the state of piping, the performance 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 drop wells, trays, the diameter and material of the pipes are fixed, 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, the reliability of thermal insulation of air intake points supply ventilation, the safety of louvered grilles and deflectors. The safety and operability of the fire smoke exhaust system is checked;
  • inspection of electrical networks, when the operability of the power supply line of the object is checked from transformer substations, where the cables are connected (in the presence of 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, and the safety of terminal devices are determined. The presence or absence of a ground loop is also noted.

A full survey of engineering systems is a rather 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 necessary to bring the engineering networks of the property to a state that guarantees the safe operation of the building and the absence of claims from supervisory authorities. This is the kind of work offered by the company "Expertsystem", which employs specialists high level using modern instruments and software for examinations.

Inspection of building structures - checking the reliability of the building

Simultaneously with the determination of the state of engineering networks, a survey of the structures of the 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 issued on ways to eliminate the identified deviations from the normative indicators. Depending on the scope of work provided for by the task, the following is performed:

  • survey of foundations with the determination of the depth of their laying, the size of the sole, and, if necessary, pits are opened, and the condition of the foundation soils is checked. Most often, simultaneously with the foundations, a basement survey is carried out, when the safety of the walls, the tightness of the entry points of engineering communications into the building, the design and safety of the floors are fixed;
  • 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 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 of the support values ​​of structural elements are also made in order to finally give recommendations for their increase;
  • 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 units of the structures are examined, while the presence, number and diameter of bolts, nuts and washers or the length and leg of welds are recorded. Based on the results of the stage of work, when the inspection of metal structures was carried out, the report proposes measures to correct the identified shortcomings, including the necessary reinforcement sketches. The results of visual and instrumental surveys are taken into account when developing design solutions for load-bearing steel structures of reconstructed buildings;
  • examination of the walls, when the thickness and material of the fence are checked, if necessary, samples are taken, which are used to determine thermal characteristics 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 of roof structures and places of their support, integrity and availability of fastening elements roofing materials with a pitched roof, the safety of gutters and pipes, the quality of the thermal insulation of the attic floor. With a flat or low-slope coating, the roof inspection consists in assessing the condition of the rolled carpet, as well as 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 complex and responsible work, when an error can lead to quite serious consequences. Therefore, enterprises providing services of this profile must necessarily have a permit from a self-regulatory organization confirming the availability of qualified personnel, as well as the necessary material base. There is such a tolerance and the company "Expertsystem".

The Expertsystem company has been performing surveys of buildings and structures in Moscow and the Moscow Region for several years, and each time the reports made by the company's specialists received positive characteristics expert bodies, and the assessment of the condition of the property became the basis for determining the fair price of the building or structure.
