Tenders Are Invited For Preparation Of Design And Cost Estimate Documentation For The Task Titled: Increasing The Retention Capacity Of A Fragment Of The Lubów Forest District In The Góra Śląska Forest District - Ii Procedure.

Material Scope Of The Subject Of The Ordera) The Subject Of The Order Are Services In The Field Of Preparation Of Design And Cost Estimate Documentation, Including Obtaining All Necessary Opinions / Arrangements / Permits / Decisions, Enabling The Ordering And Execution Of Construction Works, Along With The Authors Supervision Over The Implementation Of Construction Works Performed On The Basis Of The Design Documentation That Is The Subject Of This Order. B) The Development Of Complete Documentation Should Enable The Implementation Of An Investment Consisting Of: • Construction Of A Culvert With Damming In The Form Of A Permanent Threshold In A Dike With A Separated Fire Road J-3 332S, With Its Local Increase (Over A Section Of Approximately 100.00 M, Maintaining The Passage Parameters As A Fire-Fighting Access). This Will Allow The Flood Waters Of The Barycz River To Flow Freely Into The Oxbow Lake Area, And At The Same Time, Constant Damming, Optimally Matched To The Requirements Of The Habitats Occupying The Oxbow Lake, Will Slow Down The Water Outflow During Dry Periods. When Designing The Reconstruction Of The Dike Section, The Geometric Parameters Of The Design Speed Should Be Assumed At V = 30 Km/H. The Width Of The Hardened Road Should Be 3.5 M. The Road Surface Should Have A Load-Bearing Capacity Of At Least 10 Tons And A Vehicle Axle Load Resistance Of 5 Tons (1), • Location On The Sw B4-1 Ditch In The Section 331F Of A Permanent Damming Threshold, Stopping The Outflow Of Water From The Eastern Part Of The Oxbow Lake And At The Same Time Allowing Flood Water To Overflow. The Damming Level Should Reach A Maximum Of The Alder Root Balls Growing On The Banks Of The Ditch (2), • Reconstruction Of The Sw B4 Ditch In Order To Retain Water At The Height Of Divisions 332J / 332H. During Dry Periods, This Will Slow Down The Water Outflow - It Is A Collecting Ditch Collecting Water From The So-Called Plot. In Turn, During Flood Periods, The Flow Of Flood Waters Will Not Be Blocked (3), • Construction Of A Culvert With Damming In The Form Of A Permanent Sill In The Dike With A Road In The 330G / 330J Section With Its Local Elevation (On A Section Of Approximately 100.00 M, Maintaining The Road Parameters As A Fire Protection Access Road). This Will Allow The Flood Waters Of The Barycz And Tynica Rivers To Flow Freely Into The Oxbow Lake Area, And At The Same Time, Permanent Damming, Selected Optimally Suited To The Requirements Of The Oxbow Lake Habitats, It Will Slow Down Water Outflow During Dry Periods. When Designing The Reconstruction Of The Dike Section, The Geometric Parameters Of The Design Speed Should Be Assumed At V = 30 Km/H. The Width Of The Paved Road Should Be 3.5 M. The Road Surface Should Have A Load-Bearing Capacity Of At Least 10 Tons And A Vehicle Axle Load Of 5 Tons (4).
