Try and have the code changed.
In this case, maybe Scott Maxwell who used to be with ACI can help since he is
one of the last honorable engineers out there.
Yikes. Serious deja-vu here! Even in the frozen wastes of
North of 49, there are individuals (like some developers I have run
across - I wish!) who haven't seen that connection yet.
E.g. We can design in "plain" concrete, and our
"residential" code allows (with no reference to the need to confirm by "plain
concrete" design) top-supported basement walls up to 7'-6 1/2" with no mention
of reinforcing. It doesn't say, "Do not use rebar". It merely
doesn't say you must! But if you do reinforce, then you must comply with
the Concrete Code CSA A23, which immediately invokes minimum temperature and
shrinkage steel etc. That applies to walls as well. And
if you do some arithmetic then you will probably arrive at a required
reinforcing content. And, I've lost track of the number of
times I have been asked why I keep putting rebar into foundations that
John Doe has been building since Adam was a cowboy, without rebar!
Go figure :^)

Subject: RE: IBC "Oops" (Was Residential Design
Once upon a time I was trying to understand how the ACI 318
code was intended to apply to residential foundations. So being young I
called ACI and asked my question. The gentlemen in Skokie replied that
the particular provision in question was certainly not applicable since the
318 code had been written only for BUILDINGS, not houses.
learned that if were to continue in engineering I would be obligated to reach
my own profession conclusions as to code intent and recognize the reality that
there was always going to be someone out there that would be of the opinion
that I was wrong.
