Tenders Are Invited For Heating, Ventilation And Air-Conditioning Installation Work – Kg 430 Ventilation Systems

Heating, Ventilation And Air-Conditioning Installation Work – Kg 430 Ventilation Systems. The Existing Buildings Are Two Identical Mur Small Schools (Mobile Teaching Units). These Are Assigned To The Konrad Wachsmann School. Both Mur Buildings Were Built As Three-Story Buildings With No Basement Between 1993 And 1995. The Approximate Dimensions Of The H-Shaped Floor Plans Are Each Approx. 27.34 X 23.42 M. The Construction Was Carried Out Using Prefabricated Construction, Consisting Of Wall Panels And Ceiling Panels In Large Panel Construction. The Mur Buildings Are Accessible Via The West Facades. The Main Entrance Takes You Directly To The Respective Stairwell. The Stairwell Accesses The Ground Floor, The 1St Floor And The 2Nd Floor. The Rooms On Each Level Are Accessed Via Large Corridors. The Surrounding Walls Of The Stairwells And The Flights Of Stairs Are Solid. The Dismantling Takes Place After The Old Thermal Insulation Has Been Removed On Site. Outdoor Air Condition In Summer Case: • Relative Humidity: 40% • Max. Outside Air Temperature: +32°C Outdoor Air Condition In Winter Case: • Relative Humidity: 90% • Min. As Part Of The Modernization, The Rooms Will Be Brought Up To Date With The Latest Technology. For This Purpose, The Toilet Rooms Are Ventilated. In Addition, The Teaching Kitchen Has Circulating Air. The Exhaust Air Is Routed Via The Roof. Natural Overflows To The Toilet Area Enable The Exhaust Air To Be Extracted Into The Area Mentioned And Prevent Odor Nuisance In Neighboring Rooms. Silencers Are Provided On The Suction Side. For Cooling On-Site Electrical And Telecommunications Rooms Such As Room 13.102 “Central Security Lighting System” And Room 13.002 “Central Voice Alarm System” And “Central House Alarm System”. No Thermal Insulation Is Provided For The Toilet Exhaust Air. Suspensions, Supports, Duct Fastenings, Etc. Are Designed In Such A Way That Structure-Borne Noise Is Prevented From Being Transmitted To The Structure. Fastening Types With A Test Certificate Are Used. Any Direct Contact Of The Ventilation Pipes With Solid Components (E.G. Walls, Ceilings, Cladding) And Other Pipes Must Be Avoided. In Accordance With The Fire Protection Certificate, Maintenance-Free Shut-Off Devices (Avr) Are Installed In Accordance With The Requirements When Penetrating Ceilings With Fire Protection Requirements. The Fire Protection Components Are Installed In Accordance With The Valid Test Certificates. The Crossings Of Ventilation Ducts Through Other Fire Compartments Are Carried Out In Accordance With The Requirements Of The M-Lüar, Provided No Shut-Off Devices Are Installed. No Significant Vibrations Are To Be Expected From The Ventilation Systems Themselves. Moving Parts Such As Fans Are Installed To Dampen Vibrations. The Installation On The Building Is Decoupled From Vibrations (E.G. Insulation Panels Or Strips). The System Is Operated Via A Timer From Monday To Friday 8 A.M. To 4 P.M.
