Tenders Are Invited For Construction Of A Sanitary Sewage And Water Supply Network In Gołanice In Plot No. 324/14 And 363/4 - Local Initiative

1. The Subject Of The Order Is The Construction Of A Sanitary Sewage System And A Water Supply Network In Gołanice In Plot No. 324/14 And 363/4 - Local Initiative.2. The Scope Of Works To Be Carried Out Includes: 1) Construction Of The Water Supply Network In Gołanice In Plot No. 324/14 And 363/4 - Local Initiative. The Scope Of The Construction Of The Water Supply Network Includes In Particular: - Pvc Pipe Dn 110 Mm, Pn10, Length 329.23 M - Above-Ground Hydrant Dn 80 Mm - 3 Pcs. - Cut-Off Chute, Cast Iron, Dn 100 Mm - 1 Pc. The Designed Pvc Water Supply Network, Dn 110 Mm, Will Be Supplied From The Existing Pvcn 90 Mm Pvc Network In The Plot With Registration Number 363/4 - Designed Node W1-Z. In The Designed Node W1, Install A Barefoot-Flange Tee Dn 90/80 Mm, Reduction Cast Iron Flanged Dn 80/100 Mm And A Cast Iron Gate Valve Dn 100 Mm Cutting Off The Planned Water Supply From The Supply. Above-Ground Hydrants Dn 80 Mm Were Designed In The Network - Node W2hpn1, W3hpn2, W4hpn3. Pipe Parameters: Use Pvc Pipes Dn 110 Mm Pn 10, Sockets Connected With Rubber Gaskets.2) Construction Of A Sanitary Sewage Network In Gołanice In Plot No. 324/14 And 363/4 - Local Initiative. The Scope Of The Construction Of A Sanitary Sewage Network Includes In Particular: - Construction Of A Sanitary Sewage Network - 300.33 M, - Construction Of A Pressure Pipeline - 293.80 M, - Construction Of A Sewage Pumping Station - 1 Pcs., - Development Of The Pumping Station Area - 1 Set. Due To The Impossibility Of Direct Gravity Drainage Of Sewage Into The Existing Pvc Sanitary Network Dn 200 Mm, A Sewage Pumping Station Was Designed In Plot No. 324/14. Sewage Will Flow By Gravity Through A Pvc Dn 200 Mm Conduit To The P Sewage Pumping Station, And From It It Will Be Pumped Through A Dn 90 Mm Pe Conduit To The Sr1 Expansion Well With An Inflow Elevation Of 108.14 M Above Sea Level. Outflow From The Expansion Well Through A Pvc Dn 160 Mm Gravity Conduit To The Pvc Dn Existing In The Sanitary Network. 200 Mm - A Concrete Well With A Bottom Elevation Of 107.12 M Above Sea Level, - Water Tightness In Plot No. W10, - Frost Resistance F-150. The Wells Should Be Made Of Concrete Class C35/45, - Water Absorption: Monolithic Bottom, Factory-Equipped With Steel Manhole Steps, Covered With Light-Colored Pe, And Topped With A Concrete Cover Dn 1240 Mm, 200 Mm Thick, With A Load Capacity Of At Least 400 Kn And A Cast Iron Manhole With A Concrete Filling, Dn 625 Mm, Class D400 - In Accordance With The Pn-B-10729 And Pn-En124 Standards. Manholes Should Be Secured Against Shifting With A Concrete Ring 900*1300*200 Mm. Parameters Of The Conduit Pipe: - Gravity: Pvc Pipes Dn 200 Mm, Solid, With Circumferential Stiffness Sn8 With Factory-Installed Gaskets Securing The Gasket From Sliding Out Of The Socket Groove (E.G. Sin Lock), And With The Manufacturers Internal Print Enabling Identification Of Parameters During Tv Inspection. - Pressure: Pe Pipes Dn 90 Mm, Pn10. - Connecting Pipes By Butt Weld
