In what cases is the examination carried out? utility networks buildings. List of primary documentation for starting a communications survey, conducting an examination and drawing up a technical report.
A comprehensive analysis of buildings requires an examination of external utility networks and internal systems communications in order to determine the technical condition of equipment and its elements. The expert assessment procedure is mandatory when it is necessary to justify a decision on the possibility of complete or partial reconstruction, major repairs 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 supply systems, sewerage systems, 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, the design of new utility networks and systems, determine the possibility of connecting additional equipment and calculate the amount of work.
Technical documentation for starting a communications survey
According to regulations, before starting work, surveyors must familiarize themselves with the current technical documentation of the building's utility networks.
Drawing up a work plan, setting tasks and examination to assess the technical condition is carried out for the following objects:
- multi-storey residential buildings and cottage communities;
- public institutions (hospitals, clinics, kindergartens, schools, educational institutions);
- office buildings (including the surrounding area);
- industrial facilities, warehouses and production premises;
- 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 data sheets of the equipment used in utility networks, and operating certificates. All standards, work regulations and requirements are set out in GOST R 53778-2010.
Scope of work on the study of utility networks
In every special case carry out not only analysis technical documentation, but also instrumental diagnostics, and also visually inspect all important components in order to search for defects and worn parts. In addition, surveyors Promterra company, if necessary, search for hidden underground communications using special equipment.
The performers are faced with many functional tasks, since in the process it is necessary to inspect internal and external utility networks and 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 outdated must be replaced. To confirm, specialists 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 it will take for a high-quality inspection of the foundation and underground part of a 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, the density of their placement, and the features of the structure. Performers set the terms and volumes of expert work on an individual basis.
Upon completion of the examination of all external and internal communication systems, a technical report is drawn up. It displays the results of research, brief operating conditions for utility networks, and analysis of the facility in accordance with the requirements regulatory documents and the expected causes of the detected defects. One of the important sections of the conclusion is the justification of design decisions that are required for the repair or modernization of water supply systems, heating networks, sewerage, ventilation and electrical networks of a building or territory. SRO certificates must be attached at the end of the document.
