Tenders Are Invited For Repair Of The Odenbach Water Piping In Blens - City Of Heimbach

The Flood Disaster In July 2021 Caused Damage In Many Places In The Heimbach Urban Area, Including: Also In Blens.The Odenbach Runs In The Town Of Blens, Which, According To A Tv Survey, Shows Considerable Damage Immediately Before It Flows Into The Rur. The Existing Dn 800 Pipeline Has Collapsed Below A Built-Up Area. This List Of Services Includes The Work Necessary To Renew The Outlet Section Of The Odenbach Pipeline Into The Rur Over A Length Of Almost 50 M. At The Same Time, The Existing Pipeline Dimensions Are Expanded To Provide Higher Hydraulic Performance. The Plan Is To Lay A Pipeline In Dn 1200. Since The Pipeline Is Built Over, A Slightly Modified Route Must Be Found, Which Was Routed Under A Garage With A Workshop Warehouse For A Carpenters Shop. In Order To Be Able To Carry Out The Measure, The Garage And Part Of The The Workshop Warehouse Will Be Demolished And Restored. There Is A Reinforced Concrete Retaining Wall Facing The Adjacent Property. The Retaining Wall Will Probably Have To Be Partially Removed During The Construction Work And Will Have To Be Rebuilt. However, As Far As Possible, The Retaining Wall Should Be Retained, Among Other Reasons, But Also Due To The Proximity Of The Existing Development To The Pipeline Route, The Sewer Trenches Must Be Secured In A Force-Fitting Manner Using Chamber Plank Shoring. In Order To Minimize The Impact Of Excavation Pits On The Surrounding Area Hold, The Deepening Areas For Sewer Construction Should Also Be Secured And Narrowed With Chamber Planks In The Areas Where Construction Pits Are Necessary. The Existing Pipeline Will Be Partially Dismantled And Filled And Partially Darkened.
