Sakhnovsky — Sak to most everybody — though clearly no spring chicken, unstoppably shuttles between numerous mockups. Sak tinkering in his spotless, state of the art laboratory.

Structural steel is used again and again to make each custom-configured chamber. Looking closer, however, you notice that the steel has an odd appearance. Some pieces are old, some new. It is more of a patchwork quilt made of conglomerated hunks of steel, wood and concrete.

The vintage steel has been used, reused, and used again. It has been cut, moved, welded, cut, drilled, sealed, cut apart, craned and bolted.

It aaam seen searing Florida sun, torrential rainfalls, and uncountable performance tests. Now about the tests… A typical test sequence for a prominent building aa,a Chicago would list as follows:.

A brief explanation of each will be worth your while. Remember that each mockup is sealed to a reinforced steel box. This allows the lab to use big blowers to force air into or out of the chamber and apply powerful forces to the test specimen.

Air Infiltration The first step in an air infiltration test is to mask off the “specimen” – that’s the assembly you intend to test – and measure the airflow through the chamber. This allows you to isolate the air infiltration attributable to the specimen. In this test, lab personnel pump air from the chamber with a blower while measuring the amount of air being removed while maintaining test pressure, often 6. Using plastic film sequentially removed, the lab determines how much air is passing through each element of the mockup.

Air tests can be harbingers of results to come, so we participants tend to hold our breaths awaiting the outcome. Static Water Penetration 50.11 spray rack is used to apply hurricane-volumes of water to the test specimen while blowers are used to create a negative pressure on the inside. If the 501.11 sucks in uncontrolled water, the test is a fail, and that sucks because the testing cannot proceed until the leak is diagnosed and fixed. The lab removes air from the chamber to achieve test pressure while dousing the mockup with hundreds of gallons of water delivered by large spray racks.

Witnesses such as myself are inside the chamber with flashlights and scuba tanks aamaa looking for leaks. The test runs for 15 very long minutes. Drowning during this test is infrequent, however heat exhaustion is a distinct possibility because the chamber air 50.1 often fights a losing battle against a baking Miami sun. Dynamic Water Penetration In the dynamic water test, an airplane engine is used to aamaa a barrage of water spray against the specimen.

The violent buffeting action of the air aana has been known to shake qama dentures out of witnesses inside the chamber. Same spray rack, also 15 minutes.

This time the pressure comes from a very large airplane engine which roars to life with an explosion of smoke and oil, and rattles the bejeesus out of the specimen and the witnesses inside.

When this 501.1 takes place, about a third of the lab must run for cover and those of us inside the chamber have aamw of time to mentally review our estate planning. This procedure is AAMA Uniform Load Deflection These are just a few of the many gauges used to measure deflection of every part of the specimen while it is being subjected to wind loads far greater than anything the building will see in its future service life.

Lab personnel attach an impressive array of dial indicators on various parts of the specimen, then chamber pressure is cranked up. The indicators record the amount of deflection bending which occurs.

Yes, glass does indeed bend, Virginia, but it also breaks. Therefore standing near the mockup during this test without a suit of armor is discouraged. According to me, diagnosing and fixing the leaks can take many frustrating days. You might imagine the foreboding we feel when re-entering the chamber for a water test wama our windows have been bent like a banana during the deflection test.

We might as well 5011. any return flights for the immediate future. Any permanent bending or breakage would constitute a failure.

Usually somewhere around this point in the sequence, participants have the suicide hotline on speed dial. Test Anxiety Surviving the testing program is only one source of test anxiety. Usually the manufacturer forgets to send something, and invariably it is the very first thing you need to install. Then a storm blows through and drenches aamz you were just about to caulk. Then you get a nasty sunburn on the top of your head which creates dandruff the size of corn flakes.

Then a huge Palmetto bug, a mutant cockroach the size of a small poodle saunters confidently by, knowing full well it could whup you and your buddies. It is a last rugged outpost of American individualism and in-the-trenches know-how. The vibe is one of fun, laughter, and comeradery forged in a nihilistic caulderon of absurdity. When we arrive, we feel a great sense of freedom and excitement.

When things get tough, we wonder if we will ever aaja.
