That's interesting. We have all of ours sealed by our FPE and they
never waiver. I hope the BIA is understanding in this case. It will be
interesting.

Ladies & Gentlemen:
We have run in to similar - not exact - circumstances on BIA Projects both
here in NM and AZ. Long story short - BIA accepted/approved similar
'contradictory' design criteria when an engineering decision/judgement was made
(i.e., plans/calc's 'sealed') by a licensed PE/FPE registered in State of
project. Actually, we have previously gotten around 0.15/OH1 densities when
our drawings were sealed by our FPE.

We are looking at a project with the BIA (Bureau of Indian Affairs).
They require all bldgs over 2000 sq ft to be Ord Grp I as a minimum in
ALL areas. We have dealt with them in the past and there seems to be no
waivering on this issue. We had a contractor in the past install Tyco
BB heads and calc'd for 0.15 gpm. Tyco had written letters that
calculating to 0.15 would be fine. But the data sheet for those heads
says light hazard. So, the BIA rejected and the attic had to be
re-piped for SSU for protection.
Now, the current project has concealed combustible spaces requiring the
specially listed heads for flat, shallow concealed combustible spaces -
Tyco CC, Viking COIN, etc.. However, we are going to have the problem
that these heads are listed for light hazard only. We can't go to SSU
because NFPA 13 states that you must use specially listed heads for
these concealed spaces. We are awaiting a response from the BIA, but I
am not expecting much help. Have any of you ever run into this? If so,
how did you address it? We can't use the only heads listed for the area
because they are only listed as light hazard and the BIA requires all
areas to be OH1 minimum. We can't use SSU sprinklers because NFPA 13
prohibits their use in these spaces. It is a true Catch 22.
