Tenders Are Invited For Building Construction Work – Renovation And Expansion Of Jahnschule Diepholz - Rain Retention Basin

Building Construction Work – Renovation And Expansion Of Jahnschule Diepholz - Rain Retention Basin. The Diepholz District Is Planning To Build A Rain Retention Basin And A Treatment Plant In Accordance With Ristwag. The Construction Project Will Be Built South Of Thouarstrasse And East Of The Jahnschule On The Existing Sports Field. The Rain Retention Basin Is Equipped With Structural Drainage, Embankment Paving, An Entertainment Path And A Ball Catch Fence. The Runoff From The Rain Retention Basin Will Be Fed To The South-Facing Lohne Via A Restrictor Structure To Be Built. The Treatment System According To Ristwag Is Integrated Into The Rain Retention Basin And Is Designed As A Sealed Settling Area With A Floating Baffle Wall And Embankment Edges. The Seal Must Be Weighed Down With A Fill Layer Against The Existing Groundwater. Within Thouarstrasse, The Surface Paving Is To Be Removed And A New Rainwater Shaft Is To Be Installed On The Existing Public Sewer. The Dn 600 Branch Leads The Drain Over The Sports Field Towards The Planned Rain Retention Basin. The Existing Ball Catch Fence Remains As A Border And Is Additionally Expanded. An Access Gate Must Be Integrated Into The Planned Fence System So That Clearing Vehicles Can Drive On The Maintenance Path. The Entertainment Path Leads Over A Ramp To The Bottom Of The Rain Retention Basin. Parallel To The Construction Of The Rain Retention Basin, The Jahnschule And The Schoolyard Are Being Redesigned. As A Result, Various Work Must Be Coordinated With Other Trades In Terms Of Space And Time. To Do This, It Is Necessary That The Contractor Provides A German-Speaking Construction Manager For The Entire Duration Of The Construction Project. The Construction Project Is To Be Completed To The North Via Thouarstrasse. The Construction Site Equipment Or Any Storage Areas Can Be Implemented On The Sports Field After Consultation With The Diepholz District.
