Restricted Tender With Participation Competition (Services)Engineering Services - Creation Of A Simulation And Analysis Of The Drainage Routes During Heavy Rainfall Due To The Increase In Heavy Rain Events And The Resulting Flooding, Which Is Also Expected Or Has Already Been Detected In The Area Of The Fulda Wastewater Association, Members Should ...  Moredue To The Increase In Heavy Rain Events And The Resulting Floods, Which Are Also Expected Or Have Already Been Detected In The Area Of The Fulda Wastewater Association, An Analysis And Assessment Of The Threats And Damage Potential Caused By Heavy Rain Events Is To Be Carried Out For The Member Municipalities Of Fulda, Künzell And Petersberg. Initial Investigations Into This Have Already Been Carried Out In Parts Of The Association'S Area In The Years 2019-2021. The Core City In The Catchment Area Of ​​The Fulda, Essentially To The West Of The Bab 7, Was Examined. The Planned Study Will Examine The Association Area That Has Not Yet Been Examined. The Area To Be Modeled Has An Area Of ​​135 Km². Two 2Nd Order Bodies Of Water, The Fulda And The Haune, And Other, Smaller 3Rd Order Bodies Of Water Run Through The Area. To Protect The Low-Lying Urban Areas, Twelve Decentralized Flood Retention Basins Were Created, Four Of Which Are Located In The Model Area To Be Examined. There Are 376.3 Km Of Canals Running In The Area Under Consideration, Which Must Be Taken Into Account In The Analysis. The Following Regulations Must Be Observed In Particular During The Processing: - Notes On The Calculation And Creation Of Heavy Rain Hazard Maps In Hesse - Brochure "Heavy Rain And Municipal Precaution" From The Hlnug - Dwa-A 118 And Dwa-M 119 - Din En 752 The Following Documents Can Be Made Available By The Client For Processing: - Summary Sewer Network Information (Network Structure, Special Structures, Results From Overload Calculations, Known Overload Points, Etc.) - Digital Property Cadastre (Alkis In Shape Format, Dxf/Dwg) - Reports And Planning Drafts (Technical And Hydrological Data) On The Decentralized Flood Retention Basins On Backwaters Of The Fulda) - Data On Land Use - Water Profiles, Data On Water Piping - Aerial Photos The Following Services Are To Be Provided: - Preparation Of The Terrain Data With Integration Of The Hydraulic Terrain Surfaces, Bodies Of Water, Canal Infrastructure, Culverts And Bridges - Evaluation Of Existing Documents On Past Flood Events And Heavy Rain Events - Creation Of A Simulation Model For Floods - Coupling The Sewer Network With The Surface Runoff - Preparation Of Historical Heavy Rain Events (Radolan Data) - Implementation Of A Flood Simulation - Creation Of Gis-Supported Heavy Rain Hazard Maps - Evaluation Of Heavy Rain Hazard Maps And Identification Of Particularly Endangered Areas, Objects And Facilities As Part Of The Project Processing, The Following Additional Services Should Also Be Processed: Lph. 1 + 2 To Improve The Flood Risk Situation On The Haune In The Margretenhaun, Böckels, Wissels And Dirlos Areas.
