This past September we completed manufacturing the structural isolation bearings that will support The National Forum of Music Concert Hall currently under construction in Wroclaw, Poland. The building was designed by Kurylowicz & Associates with acoustical design by Artec Consultants.
Our pads will isolate this world class concert hall from ground borne disturbances generated by a nearby railway. The building weighs 36,500 tons and is supported on 499 low dynamic stiffness natural rubber bearings that are 3 3/4″ thick with (4) embedded steel plates. Pads range in size from 15″ x 15″ to 30″ x 30″. Pads were designed and manufactured to yield a maximum natural frequency of 8 Hz.
We processed more than 20 tons of natural rubber and 15 tons of steel to complete the order. All of the 499 bearings fabricated were compression tested in our 375 ton capacity testing machine prior to shipment. We are pleased to enclose a photo of one of these bearings positioned on the building’s foundation and an architectural rendering of the concert hall that is scheduled to open in the Fall of 2012.
We have completed numerous structural isolation projects using both elastomeric and spring isolators. We are pleased to attach a link to our Building Isolation brochure which discusses these structural isolation methods in more detail.
Please contact us if you are concerned about rail or roadway noise and vibrations disturbing your sensitive building. We are pleased to work with your acoustical consultant and design group to develop the proper isolation solution for your project.
We look forward to hearing from you.
