The inspection services of the distribution network are divided into three sub-entities. The first sub-package is the condition inspections of the distribution network. The second sub-entity is the flight inspection of medium and high voltage overhead lines, and the third sub-entity is quality assurance services for the construction of the distribution network. The tenderer may offer in one or more sub-packages.

The condition inspection services of the distribution network include the following services:

- rot inspection of the poles of low and medium voltage lines

- condition inspection of low and medium voltage lines and inspection of the line area

- erottimien kuntotarkastus

- condition inspection of transformer substations and transformer machinery

- pienjännitejakokaappien kuntotarkastus

- carrying out grounding measurements of transformer substations and separators,

- continuity measurements of extensive grounding network and concatenated groundings

- minor repair work to be carried out during the inspection,

The estimated scope of the condition inspection services of the distribution network is annually one-sixth of the Client's low- and medium-voltage network.

Distribution network inspection services shall be provided at unit prices in accordance with the criteria of the site. Unit prices must include wages, work supervision costs, travel expenses, daily allowances, accident and liability insurance. as well as vehicle costs.

The inspection work carried out in the terrain is documented in the Client's information system. If necessary, the client familiarises the persons carrying out the inspection work with the use of the applications used in the inspection. If the Supplier changes the persons performing the inspection activities, the Customer has the right to invoice the Supplier for subsequent orientation events. In order to ensure the quality of the inspections and occupational safety, it is essential that persons other than those familiarised with the work of the Client do not carry out the inspection work. For this reason, the Supplier may not change the persons performing the inspection work without the Client's approval.

The Client shall appoint a safety coordinator from his/her organisation,

whose task is to take care of, in cooperation with the supplier,

it is the responsibility to draw up a safety document for the work to be carried out,

The Supplier shall be responsible for drawing up the safety plan.

The Supplier is also responsible for the occupational safety of its employees, also taking into account any special instructions and regulations that the Client has given to the Supplier's representatives.

The Supplier shall be liable for any damage caused to the Customer or another party.

The Supplier shall be responsible for ensuring that the persons carrying out the inspection work are sufficiently familiar with the objects to be inspected and the regulations concerning them that, in addition to defects and deficiencies, they are able to assess their impact on safety. The tenderer is responsible for ensuring that the persons carrying out the inspection work have completed preparatory training for the inspection of electricity distribution networks, as well as electrical safety and occupational safety training, and comply with the regulations on electrical and occupational safety. For example, a distribution network condition inspection training or other similar training arranged by Adato can be accepted as preparatory training for the inspection.

The scope of the flight inspection of the medium and high-voltage overhead line network is approximately half the length of the entire overhead line network each year. The number of flight inspections is given in Annex 2. The flight inspection service shall have at least the following functionalities:

- laser scanning of Johtokatu and Vierimetsä

- photographing the components of the cord, the images should be so accurate that the models of the components can be identified from them, as well as defects visually noticeable in the components

- general description of the lead street

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

- automatic analysis of the rolling forest on the main street, definition of the need to remove branches and edge trees, and action plans

- Visual inspection of the wire and its components and documentation of fault findings either during the flight or alternatively using image data after the flight. If the visual inspection is carried out after the flight, the inspection must be completed and reported no later than 3 months after the end of the flights.

- Photographs of all visual inspection defect findings

- Reporting of the results of the inspection (photographs, laser scanning data, analyses, action plans) in a web interface that is available to the Client at least 12 months after the end of the inspection without a separate fee

- transfer of inspection results to the Subscriber's network information system and, if necessary, to another data warehouse.

The unit price of the flight inspection shall include the helicopter used for the flight inspection, including all costs, transfer flights, inspection flights, pilot's and inspector's salaries, official fees related to flight operations, inspection system and reporting interface.

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

- Inspection of the deployed distribution network

- Monitoring the quality and safety of network construction

The inspection of the commissioned distribution network consists of inspecting the built parts of the network on the basis of the actual documentation provided by the contractor. The inspection includes the inspection of built transformer substations, distribution cabinets, poles, separators, excavation and overhead line routes. The verification shall also include verification of the protocols of entry into service and the records.

The supervision of the quality and safety of network construction includes quality control during construction work in accordance with a separate quality control plan. Quality control includes inspecting the essential work phases recorded in the plan, such as the foundation of a transformer substation, trenches, cable terminals and extensions. Safety supervision includes, for example, making safety observations at the construction site and making MVRS measurements or inspecting MVRS measurements prepared by the contractor, checking the compliance of installations and the material used with standards and instructions, and compliance with good installation practices. Corrective measures shall be drawn up from the findings of the supervision during work, which the inspector shall forward to the contractor responsible for the construction work and to the Client. Control also includes control over the implementation of remedies.

The quality and safety assurance service for the construction of the distribution network (in-work inspection) must be started within 48 hours of ordering the inspection work. The inspection of the commissioning distribution network must begin within two weeks of the order of the inspection work.
