Tenders Are Invited For Expansion Of The Water Supply Network And Construction Of A Water Supply Connection ... in Poland

Work Detail

The Subject Of The Order Is The Expansion Of The Water Supply Network And The Construction Of A Water Supply Connection To The Building Of The Village Community Center Located In Lasy, Kraśnik Commune - A Town With A Population Of Less Than 2,000. The Investment Impact Area Includes The Following Plots: Plot No. 550/11, 551/15, 551/19, 550/9, 550/5 - Due To The Location Of The Network And Connection. Construction Of A Section Water Supply Network Made Of Pe 100-Rc 110X6.6 Sdr17 Pipes With A Total Route Length Of 132.00 M. Pipes Run With A Slope According To The Drawing Of The Water Supply Network Profile. The Designed Network Runs Through Plots With Registration Numbers 550/9, 550/5. The Connection To The Existing Ø110 Water Supply Network On The Plot With Registration Number 550/5 Should Be Made Through A Flange Tee 110/110/110 With A Dn80 Shut-Off Valve. The Gate Valves Should Be Equipped With A Telescopic Casing And A Rigid Street Box, Which Should Be Paved With Concrete Blocks Measuring 0.3X0.3X0.1 And Marked With A Plaque On A Concrete Post. The Final Type Of Fittings Used For The Connection Should Be Determined After Excavating The Existing Network. The Use Of Polyethylene Pipe Connections Should Be Avoided, And If Necessary, Connect The Pipes Using Butt Welding Or Iso Connectors Intended For Pe Pipes. An Above-Ground Fire Hydrant Dn 80 With Drainage Should Be Installed In The Network. Connecting The Hydrant To The Network Through A Flange Tee. The Approach To The Hydrant Is Made Of Cast Iron Stubs Dn80 With A Dn52 Alloy Elbow. The Water To The Hydrant Is Cut Off With A Dn80 Flanged Gate Valve, Above It There Is A Telescopic Housing Finished With A Street Box. The Box Should Be Paved. End The Network With A Pipe-And-Flange Connector With A Blind Flange. Lead The Cables With A Cover Of At Least 1.80 M, Connected By Butt Welding. Changes Of Direction Using Prefabricated Pe Bends. To Mark The Water Pipeline, A Warning Tape With A Metal Insert Should Be Placed At A Distance Of 30 Cm Above The Pe Pipe. When Changing Directions, Under Gate Valves, Under The Foot Elbow In Front Of The Hydrant And At The End Of The Network, Concrete Retaining Blocks Should Be Used. The Water Supply Connection Should Be Made From The Planned Pe Ø110 Water Supply Network To The Existing Connection Section. Water Supply Connections Should Be Made Of Pe-Rc Pe100 Sdr 11Pn 16 40X3.7 Pipes And Fittings. The Total Length Of The Connection Route Is 25.50 M, The Cables Are Run With A Slope According To The Drawing Of The Water Supply Connection Profile. Connection To The Network Should Be Done Using A 110/40 Reduction With A Dn40 Shut-Off Valve. Any Bends In The Connection Should Be Made Taking Into Account The Bending Radius Depending On The Temperature During Installation. At Temperatures Above 20˚C, The Bending Radius Will Be 20 X Dz, For Temperatures In The Range Of 10-20˚C - 35 X Dz, And For Temperatures 0-10˚C - 50 X Dz.
