Tenders Are Invited For Engineering Services – Blb Nrw D/Düsseldorf/D-Hhu 25.00 Exchange Of Air Conditioning Systems: Structural Planning - 065-26-00143

Engineering Services – Blb Nrw D/Düsseldorf/D-Hhu 25.00 Exchange Of Air Conditioning Systems: Structural Planning - 065-26-00143. The Requested Service Is The Structural Planning For An Existing Lecture Hall Building On The Campus Of The Heinrich Heine University In Düsseldorf. The Ventilation Systems In 10 Lecture Halls And A Cafeteria Are To Be Replaced. The Lecture Halls Are To Be Renovated In Terms Of Accessibility, Freedom From Pollutants, Energy Efficiency And Appearance. In Addition, The Existing Facade, Approx. 260 Linear Meters, Should Be Tested For Load-Bearing Capacity. Furthermore, The Existing Roofs Of The Lecture Halls Should Be Checked For The Installation Of Photovoltaic Systems. The Supporting System Of The 10 Lecture Halls Consists Of Steel Trusses With A Flat Roof, The Connecting Hall In Front Consists Of A Reinforced Concrete Support Structure In A Grid System With A Flat Roof. The Structural Planning Should Take Place During Construction And Various Construction Conditions Such As: B. New Loads To Be Introduced From E.G. B. Consider Air Conditioning Systems, New Ceilings, New Cable Routing. A Cfd Simulation Is Carried Out As Part Of The Planning. (Simulations To Check And Optimize The Room Air Flow And Thermal Conditions Using An Average Lecture Hall). This Simulation Could, For Example, Result In Installing Ventilation Devices On The Existing Roof. The Approved Existing Statics From 1972 Consist Of Various Folders Appropriate To The Size Of The Building. These Have Already Been Scanned And Are Available Digitally. In The Basic Determination It Is Assumed That The Future Structural Engineer Will View And Analyze Them. The Building Has Been Under Temporary Monument Protection Since 2024.
