Tenders Are Invited For Project Management For The Purge Ventilation Systems In The Stairwells

The Main Building Of The Rwth Aachen University Hospital Has 24 Necessary Staircases With Vestibules And Elevators. On December 23, 1996, A Fire Broke Out In An Electrical Shaft Near Stairwell C3. This Fire Incident Highlighted Serious Weaknesses In The Previous Safety Concept For Keeping The Stairwells Smoke-Free And Extracting Smoke. Based On These Experiences, The Safety Concept For The Stairwells, Including The Locks, Was Revised And Work Began On Planning To Convert The Safety Ventilation For The Stairwell Cores. According To The Fire Protection Statement At The Time, The Existing Pressure Ventilation Systems In The Stairwell Cores Were To Be Replaced By Flush Ventilation Systems. As Part Of The Construction Project Conversion Of Safety Ventilation Of The 24 Stairwells Of The Ubft, Approved By Approval In Accordance With § 80 Bauo Nw, Issued By The Cologne District Government On April 23, 2003, Taking Into Account The Associated Additions And Acceptances, The Safety Ventilation Systems For 13 Of The 24 Stairwell Cores Were Converted By 2010. Due To A Change In The Building Regulations However, The Continuation Of The Approved Construction Project Was Not Formally Possible.
