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

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 the same type of work.

Expertise should be trusted only by specialized organizations.

Examination 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 inspect both individual 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 of 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 levels 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, 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 correctness of the preparation of the necessary documents. 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.

To clarify the final cost, call the indicated number for consultation with our specialists.

The final price of work is formed on the basis of:

  • type of engineering networks;

What is a survey of engineering networks

This is a series of actions aimed at a thorough check and assessment of the technical and operational condition, functionality, the presence of defects and damage to part or the entire network, compliance with all accepted standards. It is also carried out before the introduction of additional equipment into the network in order to obtain an accurate answer whether the rules and regulations, as well as the characteristics of the system, will allow it to maintain its safe mode of operation.

We carry out such surveys of systems and networks using special equipment, we check buildings, internal and external networks, equipment in accordance with all the rules of the adopted regulatory documents. This makes it possible to determine the possibility of their further operation or improvement, makes it possible to determine the need for repairs in time, which will avoid any emergencies and save money on a complete replacement of equipment.

When we conduct a technical survey of engineering systems in Moscow:

  • If it is necessary to determine the wear of the equipment and the network as a whole, which will help in the timely solution of the problematic issues that have arisen
  • If necessary, determine the possibility of repairing and restoring the utility network
  • With a comprehensive assessment of the entire building of the enterprise for the examination of project documentation
  • To determine the feasibility of increasing the load on equipment
  • To draw up a task for documentation for the improvement, modernization and repair of engineering systems
