user-286557 - Please note that I said "REBENDING", i.e. straightening a previously bent bar. Obviously all bars get 'tweaked' slightly sometimes on the job, but substantial straightening and/or rebending is what is prohibited.
One of the disadvantages of a slab on grade home involves chasing plumbing issues years later. All drainage and water supply plumbing will be underneath the slab and essentially inaccessible without major expense.
I have often heard the comment (once from a judge) that "Ignorance of the Law is no excuse."
In construction and in some industries nominal sizes are commonly used. Actual dimensions are often slightly different. Those nominal sizes evolved from very logical reasons.
The mechanics of a sawmill are such that lumber sawing, specifically the width or thickness, is based on integer increments from center of sawcut to center of sawcut. The blade has width, so with each pass of the blade wood is lost from each piece being sawn.
This has been industry practice for decades.
If ignorance of common industry industry practice is now an acceptable reason to allege that you've been damaged, then what about Ignorance of the Law?
If I claim that I did not know that exceeding the speed limit was illegal, can I sue because I was financially damaged by the fine imposed when I was caught?
Next, the lumber industry will be sued because a Board Foot does not actually contain 144 cubic inches of wood, since a Board Foot is defined as a unit of wood that is NOMINALLY 1 x 12 x 1 foot.
This is as stupid as a class-action lawsuit many years
ago about the size of computer monitors (CRTs).
Anyone familiar with CRT monitors know that the actual visible measure was less than what the actual CRT measured. I (foolishly) signed on to that action - my award? A $5 or $10 coupon good against the purchase of a new monitor. Yippee! The plaintiff's attorneys made million$, the manufacturers got a bump in sales to offset the award costs, and the consumer got to spend money to receive their award.
I started in construction in 1969. At that time the ACTUAL size of a 4x4 measured 3-5/8" x 3-5/8". As time went on and surfaced lumber became more common, it was reduced to 3-1/2" x 3-1/2". Every source of technical data on lumber published charts listing the nominal size and then the actual dimensions.
To me, this is nothing more than a law firm out to make serious $$$ on a totally frivolous suit.
It's a shame that the CT legislature, as of 6/13/17, is holding bills hostage because of budget disagreements that could begin the process of helping badly affected homeowners.
BTW, this problem is not exclusively linked to the mentioned entities - pyrrhotite can be found in several rock types around the globe.
Would have been nice to see both the before AND after images.
Somewhat misleading title - could have been better titled "Frost-Protected Footing".
This is certainly an easy way to bend smaller bars.
HOWEVER, keep in mind 2 things - 1) There is a minimum radius recommended by CRSI for cold rebar bends - typically 3 times the bar diameter, and 2) Cold rebending of rebar is prohibited. Tighter bends run the risk of causing fractures in the bar.
So what is so new about this? Tin snips (big ones) work well for this.
ACI (American Concrete Institute) would never recommend "wet-setting" anchor bolts. The preferred method is to use a template that the bolt is attached to. In a case like this, using a narrow strip of wood with a hole for the bolt to suspend it using the nut to keep the bolt from "sinking". Concrete should be placed around the bolt and rodded or vibrated as it fills the form. "Jiggling" the bolt does not always guarantee adequate concrete consolidation around the anchor bolt.
Where's the tip about shaping the top of the concrete pier to shed water to minimize future corrosion? Even galvanized hardware will eventually rust or corrode.
