Architectural, Construction, Engineering And Inspection Services-New Return Cooling System And Distribution For The Dlr Location In Göttingen-Services Of General Planning, Performance Phases 2-9 According To Hoai. The Cooling Water Supply Of All Test And Supply Systems At The Location Of The German Aerospace Center In Göttingen Is Currently Carried Out Via Two Wet Cooling Towers Distributed On The Site, Each With Open Cooling Water Cycles And An Output Of Approx. 4.0 Mw. The Connected Cooling Water Network For Supplying The Individual Consumers Is Largely Led To Consumers Between The Individual Buildings In Supply Courses And Within The Buildings. A Small Proportion Of The Pipeline System (Supply Of Cooling Tower Building 6 - Terrain) Was Laid In The Ground Or Open (Crossing Linen Canal). In The Course Of The Ongoing Construction Project Refurbishment Infrastructure Expansion Area, The Main Cooling Water Supply For This Part Of The Area Has Already Been Reinstalled And Must Be Connected To The New Cooling Water Production In The Course Of The Construction Work. Double-Walled Pe100 Pressure Pipes With Leakage Monitoring Are Used Here In The Ground. In Normal Operation, The Cooling Water Supply Of The Complete Location With The Exception Of The Experimental Systems In Building 21 Is Realized Via The Return Cooling System On The Linen Channel. These Are Supplied By The Cooling Tower On The Roof Of The Born 21. The Cooling Tower Born 21 Can, If Necessary, E.G. B. Maintenance Work, Disorders Etc., Also Take Over The Cooling Water Supply Of The Location By Manual Switching. A Project Study Was Created For This Measure. This Is Made Available In The Course Of This Tender. The Client Decided To Implement Variant 5 (Adiabate Cooling With V Coolers). The Sum Of The Services Of All Existing And Currently Planned Future Consumers Is Approximately 19.5 Mw According To A Rough Performance Assessment. In The Course Of The Planning, The Overall Recurrence And The Outstanding Performance Measurements Must Be Finally Determined And Determined. The Investment Technology Including The Technology Center Takes Place On The Area Of ​​The Building To Be Taken Away 23. The Cooling Water Piping System Must Be Completely Renewed (Material: Pe). The New Cooling Water Supply Must Meet The Requirements Of The 42Nd Bimschv And Applicable Soundproofing Requirements. The Cooling Water Flow Temperature Should Be Max. 27 ° C. Mobile Supply Systems May Be Required During The Construction Phase. A Coordinated Cooling Water Supply Must Also Be Coordinated With The Institutes. Accordingly, The Cooling Water Production And Distribution Are Completely Renewed In The Course Of The Construction Measure And, Among Other Things. The Following Partial Services Provided: - Determination Of The Necessary Return Cooling Performance; - Pipe Network Calculation Cooling Water Network; - Disassembly Of The Existing Open Cooling Towers Linen Channel (At Born 6) And Born 21; - Optional: Demolition 23; - Disassembly Piping System; - Construction Technology Center; - Montage New Cooling Water Production In The Form Of Closed, Adiabats; - Montage New Pipeline System Including All Shut-Off And Rule Fittings; -
