Distribution network inspection services are divided into three (3) sub-entities. The first part is the condition inspection of the distribution network. The second sub-assembly is the mid-range and high-voltage line flight inspection and the third sub-assembly is the distribution network construction quality assurance services. The tenderer may offer one (1) or more sub-packages.

Distribution network fitness inspection services include the following services:

- Checking the poles of low and medium voltage lines for damage

- low-voltage and medium-voltage lines and line inspection

- condition inspection of separators

- condition inspection of transformers and transformer machines

- Condition inspection of low voltage distribution cabinets

- earthing of transformers and disconnectors

- minor repairs during inspection.

The estimated extent of the condition inspection services of the distribution network is one sixth of the subscriber's low and medium voltage network each year. Distribution network inspection services shall be provided at unit cost as set out in Annex 1. Unit prices must include salaries, management costs, travel expenses, daily allowances, accident and liability insurance. and vehicle costs. In-field inspections will be documented in 2019 using the PowerGrid Network Information System's off-site application on equipment owned by the subscriber or provider. The subscriber will change the network information system during 2019. From 2020, inspection work will be documented using the TSU Fieldwork application. If necessary, the customer will familiarize the personnel carrying out the inspection work with the equipment. If the supplier changes the persons carrying out the inspection activities, the customer shall be entitled to charge the supplier for subsequent induction events. Because of the quality of inspections and occupational safety, it is essential that non-commissioned personnel do not carry out inspection work. For this reason, the supplier must not replace inspection personnel without the customer's approval. The Client shall designate a Security Coordinator within his organization, who shall be responsible for ensuring the safety and health of the work to be carried out in cooperation with the supplier (Articles 5-9 of Vna 209/2009).

The Supplier shall be the principal contractor for the works ordered under this call for tenders. It is the responsibility of the customer to draw up a safety document for the work to be carried out and the supplier to draw up a safety plan. The Supplier is also responsible for the safety of his employees, also taking into account any special instructions and orders given by the Client to the representatives of the Supplier. The Supplier shall be liable for any damage caused to the Subscriber or any other party. The supplier shall be responsible for ensuring that the persons carrying out the inspection work are familiar with the items to be inspected and the regulations governing them, so that, in addition to defects and defects, they are able to assess their impact on safety. The tenderer shall be responsible for ensuring that the persons carrying out the inspection work have undergone preparatory and electrical safety and occupational safety training for the inspection of the electricity distribution networks and comply with the electrical and occupational safety regulations. For example, training in fitness inspection of the distribution network provided by Adato or similar training may be accepted as training for the inspection.

The annual inspection of the medium and high voltage overhead line network is approximately half of the total length of the overhead line. The amount of the flight inspection is shown in Annex 2.

The flight verification service must have at least the following functionalities:

- laser scanning of lead street and rolling forest;

- photography of the components of the line, the images must be so precise that they can identify the component models and the faults which are visible to the component;

- an overview of the street;

- Automated clearing needs analysis and action plan for the undergrowth of the street;

- automated analysis of the lead forest rolling forest, identification of the need for pruning and edging and action plans;

- visual inspection of the management and its components and documentation of the findings, either in-flight or, alternatively, in-flight imagery. If a visual inspection is performed after the flight, the inspection must be completed and reported no later than three (3) months after the completion of the flights;

- Photographs of any visual inspection defect finding;

- Reporting of inspection results (photographs, laser scans, analyzes, action plans) in a web interface that is available to the subscriber for at least 12 months after the completion of the inspection at no additional cost;

- transmission of inspection results to the subscriber's network information system and, if necessary, to another repository. The unit cost of the flight inspection shall include the helicopter used for flight inspection at all costs, transfer flights, flight inspections, pilot and inspector salaries, regulatory authority fees related to flight operations, the inspection system and the reporting interface.

Quality assurance services for the construction of the distribution network include:

- inspection of the distribution network put in place

- monitoring the quality and safety of network construction.

An inspection of a deployed distribution network shall include an inspection of the built-in network elements on the basis of actual documentation provided by the contractor. Inspections include inspections of built substations, manifolds, poles, separators, excavation and overhead lines. The inspection shall also include a check of the records of entry into service and of the markings. Network construction quality and safety control includes performing quality control during the construction phase in accordance with a separate quality control plan. Quality control involves reviewing the essential work phases recorded in the plan, such as park transformer foundations, trenches, cable terminals and joints. Security supervision includes eg. making site safety observations and performing MVRS measurements or MVRS measurements made by the contractor, verifying the installation and the materials used, conforming to standards and guidelines, and adhering to good installation practices. The findings of the on-the-spot checks shall be corrected and communicated by the inspector to the contractor and the client. Monitoring also includes monitoring of the implementation of remedies. The quality and safety assurance (on-the-job inspection) of the construction of the distribution network must be started within 48 hours of the commissioning of the inspection work. Inspection of the deployed distribution network shall commence within two (2) weeks of commissioning the inspection work.
