Re: ACI 117

With respect to the existing document,  it is extremely difficult to read because of the funky formatting.  Try being in a litigation with a short-tempered attorney, who randomly picks out line items and says "explain this one",  "explain why this one is necessary", "explain the purpose of this."
A lot of the items are fairly straightforward,  usually because they are taken from another reference such as the CRSI manual or ASTM C 94.  Other items are more obscure with numbers hanging out unattached to anything other than a lot of italics and ellipses.
The problem with the draft version is that apparently no one bothered to proof read it, leading to such interesting requirements as:
"14.6 - Concrete slump
For pipe with an internal diameter 42 in. (1.07 m) or less than or equal to 72 in. (1.83 m)"
I am still trying to figure out when 42 in. would be more than 72 in.
And  I'd probably up my estimate to 90% of the engineers designing buildings where ACI 117 is referenced have never seen it and have no idea how to use it.
Maybe there will be more responses that contradict me.
