Hope you had a great holiday! Our Mason elves were almost as busy as Santa's!
In addition to the standard high workload, our shop jumped through hoops to complete five weeks of production in three on several complex, high capacity, high deflection isolation systems. These projects included;

1. 26 Mason type KI mounts that will be embedded in and ultimately support a 21" thick "floating" concrete floor. This structure isolates a highly sensitive electron microscope at a national laboratory (classified location). Springs were selected for 4" deflection and will support over 100,000 lbs. (See photos on left)

2. 8 seismically restrained isolators to support a 360,000 lb cooling tower at the Children's hospital in Cincinnati. Springs will deflect 2" and will support loads as high as 75,000 lbs. each. These high capacity mounts are virtually impossible to adjust manually, so their design allows for adjustment with a hydraulic jack. Time was of the essence as our mounts replaced under designed isolators from an unknown competitor. (see photos below)

3. 9 high deflection seismically restrained spring mounts which will support a 103,000 lb. cooling tower at Children's Hospital in Seattle. Each isolator is designed for lateral seismic loads as high as 15,000 lbs. Springs were sized for 3" static deflection. (Sorry, no photos of this one. The shop got it out before I thought to take pictures!)

We love a challenge. Mason Industries has the best engineering and production teams in our industry, ready to help you with your most challenging projects. We get the job done. Even at Christmas.

We are pleased to announce the publication of the 9th edition of our Seismic Restraint Guidelines.

The positive response from the engineering and construction community to this design manual has been overwhelming. We have distributed some 27,000 copies since the first publication in 1999!

The manual was developed in response to the state of California requirement for "pre approved" seismic restraint hardware and details that would free them from the cumbersome task of reviewing each and every seismic brace on hospital projects. Of course the details and design guidance contained in the book are applicable on any project where seismic restraints are required, and the information quickly spread from California and is now applied by engineers and builders all around the world.

This latest edition is available on line. We have also updated our catalog C.D. with this latest information. If you would like a new C.D. and, or, a hard copy of the manual or a complete catalog, please send us your request.

We believe we have the best seismic design manual available, but no reference book, no matter how complete, can possibly cover every situation. Our highly experienced representative group and our staff of 30 engineers, (including 7 professional engineers, licensed in all 50 states), are here to help you with your design challenges. Give us a call and take advantage of our 53 years of experience. We look forward to hearing from you.

(We would appreciate it if our competitors ignore this notice)

A Richter 5.8 Earthquake with its Epicenter near Sparks, Okla. occurred on Saturday evening at 10:53. Aftershocks as high as Richter 3.0 continue to shake the region more than 24 hours after the initial tremblor.

Don't get all shook up about your mechanical, electrical, and plumbing systems. Rely on Mason Industries for the best Seismic Restraint Solutions and Material.

For over 50 years we have developed excellent seismic restraints, vibration isolators, and flexible connectors. Our seismic restraint systems have survived numerous devastating earthquakes without a single failure. You can count on Mason to protect lives, and keep equipment securely attached to the structure without interfering with vibration and noise control. People work with our company because of our ability to engineer complete seismic system solutions the first time.

Quakes can cause extensive damage to building systems.
THIS NEED NOT HAPPEN TO YOU!

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.
