Engineering Services – Black Pump Industrial Park; Modernization Of A Section Of Trap 1 Of The Wastewater Treatment Plant I (Aba I); Planning Services Lp 1-9. The Modernization Of The Relevant Canal Section Should Be Planned Taking Into Account The Boundary Conditions. The Selection Of Materials, The Dimensioning Of The Pipeline, Aids During The Construction Phase And The Determination Of The Construction Time Play A Crucial Role. A Possible Additional Coating On The New Channel Section To Improve Cleaning Performance Should Also Be Considered. The Entire Route From The Downcomer Shaft Aba I To R1.2 Needs To Be Modernized. The Section From Aw1 To Aw2 Was Subsequently Built Over And Therefore Represents A Special Case. For This Section, A Route Shift To The East Or West Must Be Examined. - Examination Of The Existing Documents, Review Of The Documentation - Consideration Of Modernization Including Suggestions For A Possible Coating To Ease The Cleaning Effort, With Hydraulic Proof (Q Target = 300 - 350 M³/H; Gravity Flow) - Modernization Of The Shafts With A Constant Pipe Length - Material Selection (Taking Into Account The Chemical Properties Of The Wastewater, The Increasing Calcification Potential, The Cleaning Technology Using High-Pressure Or Acid Flushing And Optimization Of The Cleaning Regime) - Preparation Of A Cost Estimate Including A Comparison Of Variants Made Of Different Materials (Concrete, Steel, Etc.) With And Without Coating - Classification Of Possible Construction Phases Taking Into Account Operational Periods Of Use As Well As Possible Temporary Structures / Mobile Pumping Stations For Wastewater Transfer During The Construction Phase - Implementation Period Taking Into Account The Operators Specifications - Preparation Of Approval Documents, Coordination With Third Parties - Preparation Of A Complete Document For The Funding Application (Lp 4) - The Following Are Particularly Important For Preparing The Application Construction-Related Questions Need To Be Clarified: O Proof Of Requirements O Location - Usability Of The Property O Concept - Coordination With The Preliminary Design Planning O Economic Feasibility Considerations, Variant Studies O Cost Determination
