The subject-matter of the contract is the construction of facilities associated with tasks called:
1. Tasks – Facilities requiring a building permit.
1.1 Task 11/1 (site numbers: 1.2,3,4 plot No 25/1 of registration area 0074 Strzekęcino, municipality of Śczekyno KOD of the premises 11-12-11-01, 11-12-11-02, 11-12-11-03, 11-12-11-04.
The objective of the task is to:
— Reconstruction of the former 4 pieces of ponds, dumps in disappearance without remaining parts of the heel structures. Natural flow lasting not more than 2-3 l/s observed in summer. A geological survey revealed the presence of sandy land in clays in the form of intersecting. It was designed to return to the former stacked water levels in each of the four collections. The increase of the dykes requires a embankment of 550 m³. The volume of the water mirror will be 670 m³. Surface area of water mirror – 1 270 m². The jamming element in each tank will be the monk mounted in the ‘DIAMIR’ plastic well of 600 with a wooden slide in a guide from hot galvanised wells or equivalent with the same characteristics. Peas with a crown width of 3.0 m with an inclination of both rocks 1: 2 with a geomembrane anti-filter shaft. An emergency discharge from the tube of Pragma DN 300 or equivalent is provided for each cake in the ring inserts and discharges of the overflowing string. Scarpt insurance – shooting with bionon-woven cover.
1.2 Task 11/2 (site numbers 5.6.7 plot No 261/4, land registry area 0075 Niedalino, municipality of Śczekyno KOD 11-12-11-05, 11-12-11-06, 11-12-11-06, 11-12-11-07.
The objective of the task is to:
— The use of the existing three collections located on the drainage ditch from agricultural land is intended to be used to stop direct run-off into the river Radwi. Container 05: ditch, tank 06: overflow, tank 07: wooden valve,
— The retention capacity of the three tanks will be 1 510 m³ with a water surface of 2 860 m². Geotechnical diagnosis has shown the presence of clay sands in the substrate under the upper layer of fine-grained sands. There have been changes in relation to the project included in the cost estimate and the bill of quantities. The drain from PVC pipes DN 300 and length of 53 m to the open drainage ditch was abandoned. The longitudinal profile shows the weapons in structures regulating water levels in the collections. The outflow from the upper collector was designed with a drainage ditch. Effluent of the central tank with reconstructed penetrator under the planned embankment) DN 300 hose – for 1⁄2 parts.
1.3 Task 12 (Site Number 01, item 140/1 of Manowo 0065 municipality of Manowo KOD for site 11-12-12-01)
The objective of the task is to:
— Reconstruction of the existing micro-tank by repairing the dough with ground with a DN 200 drainage hose with a storm flap below the grave and with a drainage drain in the crown of the dyke.

The objective of the task is to:
— creation of four flow tankers with a drainage pipeline. The total surface area of the water will be 8.09 ha. Water retention capacity will be 63tys.m³. The total length of the tanks from hkt 3,8 to hkt 14.2 will be 1 040 m. The drainage length of the pipeline shall be 212 m, DN 160 mm PCV. Geotechnical conditions identified by drilling 4 wells at a depth of 5 m, with existing impound structures. The jamming element will consist of peas with four monks, made in a well of 600 PVC ‘DIAMIR’ PVC wells with a wooden slide in a guide from hot galvanised tumblers, contained in these wells or wells equivalent with the same characteristics. Two wells DN 1000 DIAMIR shall be mounted on the drainage pipe of tank 14-04 on the basis of HOBAS No S-1 and S -2 on the longitudinal profile. For the construction of emergency rock overflows.3.In the route, indicative probes carried out confirming the presence of a stony layer drilled in test hole No 1 at monk 4. The Contractor shall start with the construction of a drainage pipeline with a closed monk of 4, works on the pipeline from the outlet. In parallel, the top task can be raised with open monk 3. The drainage of water from the ditch from hkt 12 to hkt 7 provides the possibility of dehydrating the pond no. 1 and raising it. This container, made up in the first place, may be filled with water. Embankment volume of 308 m³ net dykes. The surface area will be 580 m². An important element of this diaphragm will be the membrane anti-filter screen and the installation of a drainage of the interceptor. The filter route in fine sand with filter position shall be 6 x 1.5 m = 9 m.
During the works, maintain the technical conditions for the execution and acceptance of earthworks and the technical conditions for carrying out and receiving water management works in the field of hydrotechnical construction.
The detailed scope and description of the works shall include:
— Construction projects for the construction of Project Facilities for tasks 11/1, 11/2, 12 and 14 and technical specifications for the execution and acceptance of works (STWiOR), measurement of works (respectively: Annex – Introductory statement to this ToR).
These are tasks designed for which a building permit decision had to be obtained.
2. Facilities not requiring a building permit but a notification of the intention to build.
2.1 Task No 1 (site numbers 1,2,3,4): structures within the land registry area Niedalino 0075 municipality of Świeszyno. These are wood-stone overflows of items 3 to 74 and 158/1; wooden valve 1 on item 194/1 of the KOD of objects 11-12-01-01, 11-12-01-02, No 74, 11-12-01-03 at Act Nos 158/1 and 11-12-01-04 at Act No 194/1.
The objective of the task is to:
Wood-stone overflows.3. A typical degree of wood G-3 was adopted, replacing the padding with a stone layer on a geo-woven with a 40 cm up to 40 cm floor. In flooring structures, wooden oak is designed to be made with treated wooden walls with a depth of 1.5-2.0 m. Brushes typical for these lengths are 6 cm. The topping of 20 cm for floors of 20 cm should be 30 cm for higher stacks (more than 30 cm). Under the existing hydrological conditions of overflows of 1.5 + 2.5=4m – (minimum catchment areas) the crown width of the overflows will be sufficient within 40 cm. The execution of the overflows will require partial dehydration from the upper water side. Provision has been made for a temporary earth-pool with a geomembran cover and for pumping the water from the bottom of the foundation to ensure the conditions for carrying out the mark-up on the lining of the geo-woven and the construction of a sealing casing on the crumb of the leak-proof wall.
Wooden valve 1. It is envisaged to use a typical drainage catalogue structure with a short closure instead of a mobile gate of the classic solution. The primary element of the valve is a leak-proof wall. The construction of oak brushes and piles (pregnated) has been adopted. Height of stacks on the valve designed for construction up to 80 cm and light 40 cm to 50 cm. The adaptation of the typical solution consists of replacing the clayed bedding and the scarp with a 2 mm thick peeled geomembrarus. A layer of stone covering 30 cm thick over a distance of 4.0 m below and 1.5 m above the valve. The construction of the valve will require a temporary bulkhead protecting the foundational bottom from the upper water side. In the direction of lower water, the automatic drainage of the water after the temporary bulkhead has been cut off must ensure the conditions for carrying out the works. There is also provision for pumping the water from the downstream part of the bottom of the foundation.

2.10 Task No 4 in volume 0 037 m Koszalin, wood and stone transfer 1, item 360/2, object KOD11-12-04-01.
The purpose of the task is a typical water and drainage structure G-3 from the PartII catalogue to obtain a wood-stone transfer to the impoundment between 20 and 40 cm with a wood-tight wall of between 1.0 m in length and dH=20cm to 2.0 m long with dH = 40 cm, a wall of an oak impregnated. The width of the crown at the proposed location is 40 cm. The total catchment area for the 2x20ha transfer (divided by the provincial to catch). The modification of the typical G-3 step consists of introducing a rock mark-up on the geo-wovens instead of the fasin lining. The structure of the transfer is shown in Figure R-3. There is already sandy land at the bottom of the ditch in the place where the transfer is located, with organic body formations of more than 2 m in the direction of the marsh valley. The immediate vicinity of the forest road facilitates the construction of the facility. The basic element of the structure – tightening – must be made after killing the steering piles at the bottom of the ditch ensuring that a 40 cm ‘light’ is obtained. Oak pallets with guide cuttings of the wall itself. Ordering earthworks for a rock over the geo-wovens.
