The framework agreement concerns the mowing of nature-friendly banks and water storage with amphibious vehicles. Agreements will be made annually with the contractors about the deployment for a certain mowing season.

HHNK currently owns 1 amphibious vehicle and intends to purchase 1 more. Delivery expected by the end of 2024. The contractors carry out their work in addition to HHNK's own capacity.

The size is estimated at 500 hours per year per participant in the framework agreement (a total of 1,000 hours per year). By 2025, HHNK expects to have a new amphibious vehicle in use. Furthermore, HHNK expects the number and size of nature-friendly banks to increase. If the framework agreement is extended, the contractors will be consulted annually to discuss the division of the work. The starting point is a proportional distribution.

This size is based on estimates that explicitly state that no rights can be derived from these estimates.
