Mark,

Unfortunately they didn't call to discuss their concerns before putting
it in writing and rejecting the drawings. Now we have to reply in
writing through the GC and so on and so on. A giant waste of time with
no benefit to anyone.

Why don't you just call and ask where they are coming from and let them
lay
their cards on the table.  I know the FPE's at RJA in Dallas and they
are
all competent.

Tell Jim or Steve to..., well never mind. 

I don't agree to increasing the area because of a "higher potential for
fire". 

However, if the intent was to say "the fire potential is higher", that
is
larger fire area is anticipated, then I would agree. One can argue that
an
intentially set fire by the inmates is highly probable. If this is the
case,
a larger area would be proper without increasing the density because of
the
limited combustibles. The fuel load is what it is, but the quantity of
involved materials may be larger because of inmate activity. 

But, this should have been presented "clearly" in the specs.

I would like the take from the PE's on forum on how to deal with a plan
review comment from an unnamed engineering firm (RJA).

"Due to the higher than normal potential for a fire in the occupant
sleeping and common areas, the reduction in fire are (remote area) for
quick response sprinkler in accordance with NFPA #13 Figure 11.2.3.2.3.1
is not a good engineering practice. Please revise the hydraulic
calculation to account for at least the minimum 1500 square foot design
area as specified by NFPA #13."

The hazard is a dormitory at a minimum security prison.
