The subject of the contract is the construction of two unused logging routes consisting of a transverse, perpendicular to the axis, buildings of round wood with a diameter of 20 cm with ends fixed in the edges to a depth of 100 cm and lining the bottom above the partitions with coniferous or deciduous branches fixed with stakes. In order to prevent soil from being washed out by the flowing water, the bottom beams of the partition should be inserted into the bottom to a depth of at least 15 cm. Branch lining should be poured with soil from excavations for beams in the bottom and banks and additionally weighted with stone collected on site. The location, number and length of beams in a partition are indicated in the documentation on situational sketches and cross-sections. Waterfalls should be made of two single round logs with a diameter of 20 cm and the trenches should be made of trapezoidal cross-section 30 cm wide, 30 cm deep and 1: 1 slope inclination.

Surface water will be discharged through waterfalls to the adjacent area. Waterfalls and ditches should be made in places indicated in the documentation. Waterfalls should be made of two single round logs with a diameter of 20 cm and trapezoidal trenches with a bottom width of 30 cm, a depth of 30 cm and a slope of 1: 1 slopes.
