Technical inspection of electrical installations  is carried out at the commissioning of the facility and in the operation of technological systems. At the same time for newly installed electrical installations for commissioning, there is usually enough acceptance testing and a standard package of documents. Certificate of technical inspection  require when obtaining an act of admission to an electrical installation that has stood for a long time without operation. In many cases, a technical survey is the only way to legalize an electrical installation that has been used for a long time without going through the official commissioning procedure. The inspector of Rostechnadzor prescribes technical examination of electrical equipment  if there is no technical documentation for the electrical installation of the balance-holder.
  For technological equipment, a technical survey should be carried out after the end of the service life in order to determine the possibility of further operation of electrical equipment. Electrical equipment is understood as the whole set of electrical equipment, including lighting and household equipment, but the period of permissible operation of household equipment is always much greater than that of the technological equipment. In this connection, a technical survey of the technological systems (heating, ventilation, air conditioning, etc.) is more often required. According to the rules of technical operation of electrical installations of consumers, the latter must ensure scheduled preventive maintenance and maintenance of the electrical installation. Responsibility for these events rests with the head of the organization. The list and the plan of all works is approved by the head of the enterprise proceeding from the changing operating conditions of electrical equipment. For all types of work, the annual plans and schedules approved by the technical manager of the consumer are made responsible for the electric economy. At the end of the operation period established by the normative technical documentation, a technical survey of electrical installations should be carried out to assess the condition of the electrical equipment and establish new terms and operating modes. Technical survey  it is desirable to conduct using an electrical laboratory certified in Rostekhnadzor. In many cases this is a mandatory requirement.

Also technical survey of the building  is carried out according to the requirements of PJSC MOESK when the owner changes and the documents are reissued at the existing facilities. The basis for the technical survey is the entry in the authorization to join. The cost of work is determined by the graphs shown in the Prices section. In case of non-compliance, we will carry out a set of work to eliminate them (adjusting the project, agreeing documentation, etc.). The cost of additional work is determined by us in accordance with our pricing principles. The cost is the same for all and is determined by the organization accredited by MOESK for the production of a technical survey. At the moment, a technical survey on the requirements of the PJSC MOESK is not carried out due to changes in legislation!
