Tenders Are Invited For Development And Hardening Of Two Paths From The Likusy Estate To The Walking Trail At Lake Ukiel

The Development And Hardening Of Two Paths From The Likusy Estate To The Walking Trail On Lake Ukiel In Olsztyn Was Planned: • Section A - From Ul. Klonowa To The Walking Trail By Lake Ukiel, Located On Plots No. 222/2, 216;• Section B - From Ul. Klonowa To Ul. Dębowa, Located On Plots No. 113, 141, 165. The Existing Sidewalk, Approx. 10.2 M Long And 1.5 M Wide, Located In Section B, Is Scheduled For Demolition. The Task Will Be Implemented In The Following Stages: 1) Stage I - Reconstruction Of The Low-Pressure Gas Network On Section B; 2) Stage Ii - Execution Of Other Construction Works Covered By The Design Documentation. Section A Was Designed As A 1.5 M Wide Sidewalk, While Section B Was Designed As A 2.2 M Wide Sidewalk (2.0 M Sidewalk And 20 Cm Concrete Block Gutter). The Surface Of Sections A And B Should Be Made Of Non-Bevelled Concrete Cubes 15X30 Cm In Graphite Color, The Sewer At Section B Should Be Made Of Non-Bevelled Graphite Cubes 10X20 Cm. The Designed Surfaces Should Be Limited By A Concrete Edge 8X30 Cm Or A Concrete Palisade 10X10x60 Cm Or A Concrete Inrun Curb 15X22 Cm (Curb From The Side Of Dębowa Street), Placed On A Concrete Footing With A Resistance Made Of C12/15 Concrete. On Section B From The Side Of Ul. Dębowa Was Designed With A Band Made Of Non-Bevelled Concrete Cubes 10X20 Cm In Gray. On Section B With A Longitudinal Inclination Of 8.0% (Slope), A Handrail Was Designed To Be Made Of Galvanized Steel Pipes. The Railing And Handrail Posts Should Be Made Of Galvanized Steel Pipes With A Diameter Of 50 Mm. Vertical Railing Posts Spaced Every 1.5 M Should Be Placed On Point Concrete Foundations 20X20x50 Cm Made Of C12/15 Concrete. The Foundations Of The Railing Posts Should Be Located At Least 50 Cm From The Extreme Wall Of The Gas Connection. Paint The Handrails Anthracite Ral 7016. Rainwater Drainage In Section B. Drainage Of The Designed Surface Is Planned By Building An Inlet With A Sewer To The Existing Di Well. Construct The Section Under The Road Using The Trenchless Method. The Sewage Pipe Should Be Made Of Modular Pipes Ø200 Pp. Rainwater And Meltwater Will Be Collected By The Designed Street Inlet Placed On A Ø500 Concrete Well With A Settling Tank. Then The Runoff Will Be Directed To The Existing Inspection Well From Di1. A Street Inlet With The Diameter Of The Inlet Chamber Dn500 Is Designed, With A Sedimentation Tank Of H = 1.0 M Depth And A Waste Bin. Section A Will Be Surface-Drained Into Adjacent Green Areas According To The Road Industry Study. Gas Network On Section B - To Be Completed In 2026. Due To The Fact That The Existing Gas Pipeline Is Shallow, It Is Planned To Reconstruct The Low-Pressure Gas Network. The Construction Of A Low-Pressure Gas Pipeline On The G1-G10 Section Was Designed, Made Of Pipes: - Pe100 Rc Sdr17 Dn125, Length L = 79.5 M. Along The Route Of The Designed Gas Pipeline, Existing Connections Should Also Be Switched On The Following Sections: - G5-G5/1 Made Of Pe100 Rc Sdr11 Dn40
