Poland - Construction work for water supply and sewage disposal pipelines

Description

The subject matter of the order is the construction of a section of the sanitary gravity-pressure sewer network with a total length of approximately 182 m, in the village of Celestynów, Leśna Street" within the framework of the project entitled "Improvement of water and sewage management in the municipality of Karczew and Celestynów - stage II. POIS.02.03.00-00-0104/17 under Measure 2.3 "Water and wastewater management in agglomerations" priority axis II "Environmental protection, including adaptation to climate change" of the Operational Program Infrastructure and Environment 2014-2020.
The subject matter of the order includes, in particular:1) Construction of a sewer network in the gravity-pressure system with a total length of approximately 182 m from PVC pipes SN 8 (gravity network), PE 100 SDR 11 PN 16 (pressure network) and gravity sewers from PVC pipes SN 8 to the border of the plots of all developed properties. Make the gravity sewer network from PVC pipes SN 8 kN/m2 (solid walls) with diameters and gradients that ensure the self-cleaning velocities of the sewers. Pressure network should be made of PE 100 SDR 11 PN16 pipes. 2) Construction of sewer manholes DN 1000 mm. 3) Construction of sewer manholes DN 425 mm. 4) Construction of gravity sewers to all developed properties located within the project area should be brought gravity sewers made of PVC pipes Ø 160 mm SN 8 kN/m2. Terminate gravitational branches with PVC plug Dz160.5) Construction of an expansion well on the inflow of sewage from the zonal sewage pumping station to the gravity sewer system. An expansion well DN 1000 mm should be used. The well should be equipped with an anti-odor filter.6) Inclusion into the existing sewer system. The connection should be made to the existing PP Ø 1000 mm inspection well located in Osiecka Street. From the St1 well to the S1 well, the works should be carried out using the guided drilling method.7) Installation of control-measuring sparatura and automation of the zonal sewage pumping station in Leśna Street. 8) Construction of the zonal sewage pumping station in Forest Street9) Restoration of the condition of the road lane surface to the condition before the start of the works under the supervision of the works manager. 10) Obtaining a certificate of no objection from the District Building Control Inspector in Otwock.Detailed description of the subject matter of the contract, terms of execution, method of payment and other elements of the execution of the subject matter of the contract are described in the draft provisions of the contract constituting Appendix No. 7 to the SWZ, and are also described in detail in the design documentation constituting Appendix No. 12 to the SWZ.
