Tenders Are Invited For Architectural, Construction, Engineering And Inspection Services – Gep Kirchderner Graben

Architectural, Construction, Engineering And Inspection Services – Gep Kirchderner Graben. The City Of Dortmund Has An Extensive Sewer Network That Has Grown Over Decades And Is Subject To Constant Expansion, Changes And Renovations. The Continuous Development, Expansion And Conversion Of The Wastewater Network Results In Partial Changes To The Hydraulic Flow Properties Of The Sewer Network. The City Drainage Is Continuously Working To Adapt The Hydraulics Of The Entire Sewer Network To The Citys Progressive Urban Development And For This Reason Would Like To Map The Sewer Network Area For The Catchment Areas 1) Kirchderner Graben 2) Obere Körne, Flughafenstrasse In A ++Systems Project And Hydrodynamically With The Programs Have ++System Hydraulics And ++Systems Geocpm Calculated. The Current Inventory Is Documented In The City Of Dortmunds Sewer Database. The Data Is Provided By The Client. For The Kirchderner Graben Area, The Scharnhorst Zap Node Can Be Used. A Hydrodynamic Inventory And Forecast Calculation From 2011 Is Available For Comparison. No Data Is Available For The Obere Körne, Flughafenstrasse Area. The Study For The Areas Of Kirchderner Graben And Obere Körne (Flughafenstrasse) Is Necessary In Order To Gain Knowledge About The Drainage Behavior Of The Sewer Network And To Make A Contribution To The New Holistic Sewer Renovation Strategy Of The Dortmund City Drainage System. The Aim Of The Gep Should Therefore Not Only Be To Target The Hydraulic Performance Of The Sewer Network, But Also To Take Into Account Structural And Other Water Management Issues And The Consequences Of Climate Change In The Sense Of A Holistic Strategy. A Mapping Of The Areas Connected To The Sewer System That Is As Correct As Possible Usually Has A Positive Effect On The Reported Renovation Effort And Thus On The Resulting Investment Costs. The Model Should Therefore Be Calibrated With The Aim Of Determining The Actual Degree Of Connection Of The Areas With An Impact On Runoff. Against The Background Of Flood Prevention And To Realistically Depict Surface Flow Processes When The Network Is Overloaded, Coupled Hydrodynamic Simulation Calculations Must Be Drawn Up. As An Addition To The Network Display In Accordance With Section 57 Lwg, Load Cases Above The Limit Values ​​Of Din 752 Are Also Considered As Part Of Heavy Rain Risk Management. The Hydraulic Calculation Must Be Carried Out Using The ++Systems Hydraulics Software From Tandler.Com. A Configured Empty ++Systems File Is Handed Over From The Dortmund Municipal Drainage (Ag) To The Engineering Office (An). This Serves As The Basis For The Sewer Network To Be Built And The Presentation Of The Results. It Is Taken Into Account That The Profile Identifications In ++Systems And The Channel Information System Novakandis Are Subject To Different Conventions. Required Modules Are ++Systems Hydraulics As Well
