So here is the pessimist in me coming out, so forgive me beforehand. But anytime you try and replicate a real life scenario in a lab, the results can be just slightly off the real thing. Britain made the first commercial jetliner and did all of their pressure tests in a lab. After 2 crashes killing all the passengers on board, because of stress failures at square windows due to real life compression/decompression, the company eventually quit making planes..
When you are dealing with something like RESIDENTIAL CONSTRUCTION, there is so much variance in the quality of the design and construction, I cannot see what this will really tell us. I understand CA is pretty strict with plan review, who designs houses, and inspections, but from what I gather the rest of the country is not the same.
So, my real life test would be:
-Have a "designer" draw up the plans, and guess at the connections. Maybe let an architect with limited structural knowledge sign and seal it, or an engineer who doesn't care how he makes $500 blindly seal it.
-Let a GC build it on the fly using prescriptive codes
-Do not have an engineer do any site observations, because his CA fee is WAY too high
-Have the inspector stay in his truck for the inspection, not bring his ladder because of liability, or spend a half hour taking a quick glance. Or allow the scientists at the lab to "good ole boy" their way out of the inspection.
-Allow the builders to substitute connections, change details, or make modifications at will
-Allow drinking during construction
-Have the majority of the work done by unexperienced, unsupervised workers who just got here from a poor country without similar construction. They cannot speak english or read the plans. (Don't read into this comment, it is not about immigration, about unskilled workers.)
-If there are plans on site, they are over in the corner all dirty and tattered..
Now throw it on the table and let it shake....
