Tenders Are Invited For Architectural, Engineering And Planning Services – Town Hall Porscheplatz 1, 45127 Essen, Specialist Planning Services For The Renovation Or Renewal Of The Large-Scale Refrigeration System

Architectural, Engineering And Planning Services – Town Hall Porscheplatz 1, 45127 Essen, Specialist Planning Services For The Renovation Or Renewal Of The Large-Scale Refrigeration System. Analysis, Evaluation And Variant Investigation Of The Existing Refrigeration System, Taking Into Account Ongoing Building Operations As Well As The Structural And Technical Framework Conditions. The Object Of Investigation Is A Special Building With A Building Height Of Approx. 106 M. The Technical Infrastructure Is Vertically Organized And Highly Hydraulically Networked. The Investigation Is Carried Out Under The Conditions Of A Permanently Operated Building. The Cooling Is Supplied Via A Central Cooling Generation In The Basement (U3). The Recooling Takes Place Via Recooling Plants Arranged On The Roof. The Connection Between Cold Generation And Recooling Takes Place Via Vertical Riser And Downpipes Over The Entire Height Of The Building. The Cold Is Distributed Via A Horizontal Distribution Network And Via The Ventilation Systems Of The Usage Units. The System Is Hydraulically Networked Throughout And Should Be Viewed As An Overall System. The Aim Of The Study Is To Develop A Reliable Basis For Decision-Making For The Future Use Of The Refrigeration System, Taking Into Account Operational Safety, Economic Efficiency And Technical Feasibility In Ongoing Building Operations. Scope Of The Investigation And Questions As Part Of The Feasibility Study, The Contractor Must Work On The Following Aspects In Particular: - Determination Of The Actual Condition Of The Entire System (Generation, Recooling, Distribution And Overall Hydraulic System) - Analysis Of The Causes Of The Corrosion Problem, Taking Into Account The Material, Mode Of Operation And Water Quality - Assessment Of The Technical Criticality Of The Corrosion Damage In Terms Of Damage Progression, Risk Of Failure And Effects On Operational Safety - Assessment Of The Influence Of The Open Cooling System On The System Condition - Assessment Of The Effects On Operation, Functionality And Security Of Supply - Classification Of The Damage As Locally Limited Or Systemically Effective - Estimation Of The Remaining Technical Service Life Of The Existing System - Development Of Technically And Economically Suitable Future Strategies It Is Intended To Also Have The Contractor Carry Out The Subsequent Structural Implementation Of The Measures Based On The Hoai As An Option.
