The procurement will be divided into three sub-packages, with the first sub-package being demolition of high and medium voltage lines, clearing of low voltage lines, vending and felling of edging trees, collection and transport of clearing trunks, other clearing and inspection work and supply of wood in the vicinity of electricity distribution networks. The second sub-entity is the logging assistance reception service and the third sub-entity is helicopter sawing.

Providers of the first sub-package must attend, at the request of the subscriber, a standby to prepare for clearing fallen or inclined trees in the vicinity of the wires during or after a storm. Partial bids shall be accepted in such a way that the tenderer may bid for one (1) or more sub-lots.

The package includes the following services:

- clearing of the bottom of high voltage lines (110 kV)

- clearing the bottom of medium voltage conductor lines (20 kV)

- clearing of low-voltage overhead lines (0.4 kV)

- clearing of low voltage (0.4 kV) low voltage conductor lines (AMKA)

- Vomiting of edges of medium voltage conductor areas (20 kV)

- Falling edge trees adjacent to low and medium voltage lines

- collecting and transporting clearing scraps to a collection point

- other clearance work or clearance tests

- use of other tools used by the provider

- Logging assistance in the vicinity of medium voltage (20 kV) lines

- Logging assistance in the vicinity of low voltage lines (0.4 kV)

- emergency clearance in case of storm threat.

Bottom clearing refers to the clearing of the bottom of the guide area so that after the clearing, the snowmobile, ATV or foot can be moved. This requires that, after clearing, there are no heights greater than 10 cm high in the guide area and that the heels are straight. Bottom clearing is done either by clearing saws or alternatively by machine. When clearing the bottom, individual trees growing outside the street that have a significant risk of falling over the cable are removed. Edge vowing means cutting off the branches of trees growing at the edge of the guide so that the branches do not extend into the guide. The pruning should be done in such a way that the growing trees are not unnecessarily damaged. The width of the cord varies with the type of cord. The appendices to the invitation to tender indicate the requirements for the width of the street for the different types of cable. Collecting scraps and transporting them to a collection point means taking branches, etc., to a pre-agreed location. If the Tenderer has access to a toolkit that can be used by a subscriber for jobs other than those mentioned in this call for tender, the Tenderer may provide the tool to the subscriber by identifying the tool in the unit price list and setting a unit price for the tool. The provider may choose the unit to be used for the unit price. The clearing work is ordered mainly by electronic work orders. The provider acknowledges daily clearing work in the subscriber's information system. The provider is responsible for printing any necessary clearance maps. The tenderer shall be responsible for the necessary licensing of trees felled off the main street. The Logging Assistance Service provides advice and assistance to the subscriber's customers in cases where logging may pose a risk to the logger due to a live electricity distribution network or where logging may damage the power grid. The felling assistance service does not include the felling of the tree itself, except in special situations where the felling threatens only the subscriber's electricity distribution network or the tree is located in the immediate vicinity of the medium voltage line. In these situations, the felling of wood is free of charge for the customer of the customer. In connection with the logging assistance service, the provider may also provide the subscriber's customer with a logging service, from which the provider will invoice directly to the end customer.

Sometimes felling wood is challenging, especially in urban areas on narrow plots. Tenderers are asked to explain the method by which they perform felling of wood in confined conditions with minimal risk of damage to all parties involved. The provider must be prepared to deliver the felling or felling assistance in the vicinity of the PJ network for a week and a few days for the KJ network. The tenderer shall be requested to ascertain how the tenderer is able to meet the need for the service at that time. Logging assistance tasks are routed to the provider through a subscriber task management system. The provider is responsible for scheduling the tasks and documenting the execution of the task in the task management system of the subscriber.

Receipt of timber felling orders includes receipt of timber felling orders by telephone, e-mail or electronic form, as well as notifications of trees posing a hazard to the power line, entry of orders into the contractor's task management system, and forwarding to the logging and clearing contractor. The call reception service for logging assistance orders must be available to the subscriber's customers on weekdays from 8:00 to 16:00. Orders must be logged at the same time in the subscriber's task management system. Orders received by email or electronic notification channel must be logged in the subscriber's task management system within one (1) business day. The tenderer must provide an explanation of how the order pick-up service is organized.

Helicopter sawing services include the grafting of medium-voltage wire-line edge trees along the entire length of the frame and the high-voltage (110 kV) wire-line edge tree top sawing. Grafting is carried out on the basis of a clearing need analysis performed by laser scanning of the wired streets, with the wires having the greatest need for clearing, but with the selected clearing area being an integral whole. Beam sawing is done for trees whose tops can fall over the conductors of the 110 kV line. The customer provides the location information of the trees to be cut. Estimated purchases of helicopter sawing services are provided in Annex 2.

The tenderer shall document the clearance made to the Flyspect flight inspection and reporting system used by the subscriber. The subscriber must be able to monitor the progress of the clearance in real time. During the helicopter sawing, the contractor arranges a sub-contractor who removes any branches that have fallen on the power line and contributes to ensuring safety. The contractor is responsible for training the deputy before commencing sawing. The language of communication between the deputy and the pilot flying saw is Finnish. The tenderer must provide a description of the equipment used for the clearing and the experience of the clearing staff in carrying out the works requested in the tender. The provider must have a security system in place. Turbine-powered helicopters and CE-approved saw equipment must be used for sawing. A pilot helicopter pilot must have at least 250 hours of flying experience.
