10. Executive Schemes - Plans with Engineering Systems

In which cases are carried out engineering networks Buildings. List of primary documentation to start communications surveys, examination and technical conclusion.

In comprehensive analysis of buildings, examination of external engineering networks is required and internal systems Communications to determine the technical condition of the equipment and its elements. The procedure for expert assessment is obligatory when it is necessary to justify the decision on the possibility of full or partial reconstruction, overhaul and upgrades of the object under study.

The essence of the survey is to study the functional characteristics, their compliance with the current technical standards and design and executive documentation of water pipelines, sewage, ventilation mines, heating systems, gas supply and other engineering equipment. Based on these data, experts will be able to provide recommendations for the operation or dismantling the old design of new engineering networks and systems, determine the possibility of connecting additional equipment and calculate the scope of work.

Technical documentation to start communications surveys

According to regulatory provisions, before starting work, the surveyers should familiarize themselves with the current technical documentation of the building engineering networks.



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

  • multi-storey residential buildings and cottage settlements;
  • Public institutions (hospitals, clinics, kindergartens, schools, educational establishments);
  • office buildings (including nearby territory);
  • Industrial facilities, warehouse and industrial premises;
  • Technical structures and agricultural structures;
  • Sports centers, stadiums, ice palaces;
  • Building urban infrastructure.

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

The composition of the work on the study of engineering networks

In each case, not only the analysis of technical documentation is carried out, but also tool diagnostics, as well as visually examine all important nodes in order to search for defects, worn out parts. In addition to this geodesists Company "PROMTERRA", if necessary, search for hidden underground communications With the help of special equipment.



There are many functional tasks in front of the performers, since in the process it is necessary to examine domestic and external engineering networks, to evaluate the technical condition:

  • hot and cold water supply;
  • heating and heat supply;
  • internal ventilation systems;
  • sewage and sebuming;
  • gas supply systems;
  • drainage and heat seafood;
  • external electrical networks;
  • engineering equipment.

Equipment that is physically worn out and outdated must be replaced. To confirm, experts perform verification calculations. The survey allows us to evaluate the scale of work, including financial costs. If necessary, selectively can be assigned tool measurements of places and elements. In the process of conducting examination, it is necessary to make clear photos of damage detected.

Technical Conclusion and Terms of Examination

How much time it takes to a qualitative examination of the foundation and underground part of the building with the presence of engineering networks, depends on several factors: the complexity of the object under study and its size, customer requirements, and the need to detail the data, technical characteristics Communications, density of their placement, features of the structure. Dates and volumes of expert work performers are individually established.




At the end of the examination of all external and internal communications systems, the technical conclusion is made. It displays research results, brief conditions operation of engineering networks, an object analysis in accordance with the requirements regulatory documents And the estimated causes of the appearance of detected defects. One of the important sections of the conclusion is a substantiation design solutionsRequired to repair or upgrade water pipelines, heat networks, sewers, ventilation and electrical networks of the building or territory. At the end of the document should be attached evidence of SRO.
