The Subject Of The Order Are Construction Works, I.E.: 1) Task No. 1: Construction Of A Water Supply Network With Infrastructure; 2) Task No. 2: Construction Of A Sanitary Sewage Network With A Pumping Station, A Pressure Pipeline With Reinforcement And A Metered Power Supply Line On Plots No. 201/1, 201/2, 205/2, 205/3, 205/4, 194/1, Located Within Niżna Łąka, Głos Piastowe Commune. 2. The Scope Of Works For Individual Tasks Is As Follows: Task No. 11) Construction Of A Water Supply Network With Infrastructure: A) Water Distribution Network With A Length Of Approximately 560.0 M, B) Water Supply Network Infrastructure Includes The Installation Of Shut-Off Valves And Above-Ground Dn 80 Mm Hydrants, C) Pipeline Foundation Depth Min. 1.65 M From The Pipeline Axis, D) The Water Supply Network Will End With An Above-Ground Hydrant, E) Reinforcement Of The Water Supply Network: Flanged Ductile Iron Gate Valves, Gate Boxes, Cast Iron Elbows With N Foot, Fire Hydrants. Task No. 2 1) Construction Of A Sanitary Sewage System With Infrastructure: A) Construction Of A Sewage Network Made Of Pvc 200 Pipes With A Length Of Approximately 320.0 M, B) Foundation Depth: Min. 1.4 M.2) Construction Of A Sanitary Sewage Pumping Station, Pressure Pipeline With Infrastructure: Due To The Slope Of The Land Opposite To The Depression Of The Existing Municipal Sewage System, It Is Necessary To Build A Sanitary Sewage Pumping Station On Part Of The Area Of ​​Plot 201/1. The Pumping Station Tank Will Be Made Of Pehd Structural Pipe. The Pumping Station Will Be A Prefabricated Element Delivered To The Construction Site As A Ready-Made Object In Accordance With The Technical Data Included In The Design Documentation. Sewage From The Pumping Station Will Be Discharged Through The Designed Pressure Pipe To The Existing Municipal Sewage Network Located On Plot 205/4. The Pumping Station Area Will Be Fenced And The Surface Around It Will Be Hardened. The Pressure Pipeline, Approximately 351.0 M Long, Will Be Made Of Polyethylene Pipes For The Pressure Sewage System. The Minimum Earth Cover Of The Designed Pressure Pipelines Should Be 1.4 M, Counting From The Ground Elevation To The Top Of The Pipeline. A Cleaning Well Equipped With A Flushing Connector, A Compensator, Shut-Off Gate Valves And An Expansion Well Will Be Constructed Along The Route Of The Pressure Pipeline. 3) Construction Of A Metered Power Supply Line: The Sewage Pumping Station Will Be Powered By A Ykxs 4*16 Cable At A Depth Of 80 Cm In Sand Bed In Accordance With The Developed Design Documentation Of The Project. Warning Foil Should Be Placed Over The Cable, And In Places Where It Crosses Other Cables Or Under The Surface Of Sidewalks Or Roads, It Should Be Placed In Protective Pipes. Other Works Necessary To Be Performed In Order To Implement This Investment: 4) Securing The Construction Site, 5) Marking Out The Route, 6) Earthworks, 7) Installation Of Pipelines, 8) Mechanical Compaction Of The Soil, 9) Geodet
