Report on the survey of engineering networks example. Inspection of the performance of engineering systems. Our proposal for the survey of engineering networks of buildings

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 communication systems 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 the regulations, before starting work, the examiners must 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 institutions);
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

Examination of 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 emergencies, 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.

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 the reconstruction or major repairs of 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. The success of possible judicial 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 on the quality and timing of its implementation, the correct execution of the necessary documents. Due to the specifics and complexity of surveying engineering systems, you should always contact only organizations with experience in conducting complex work.
