I am skeptical about the idea of a bottom level space being "unused"
in a storage warehouse. At some point, someone will figure out how to
use it and then it will be a mess. Stick with the 10 ft above the
floor, I would.

Ron,
My answer is maybe yes...but I'd like to know the full extent of the
storage before I agreed.
1. How high is the total storage? The chart is for over 25-feet high.
2. Where are the 2nd and 3rd levels of rack sprinkler located?
3. What is being stored?
Not that any of these questions make a difference, but I'd like to know
what I'm agreeing to before it's all said and done.
Another question of similar nature...If your total storage arrangement
is 35-feet high, do you design for the total height of 35-feet or only
30-feet high since the lower 5-feet is dead space?

Subject: 1st Level of in-rack sprinklers location
Anyone want to take a shot at this?
Figure 17.3.4.1.3(d) indicates the first level of sprinklers to be 10
ft. approximately from the floor and is shown above the second cube in
the elevation view.
If there is a 5 ft. dead space (empty with no storage or other
equipment) from the floor to the bottom of the first level of storage
could the first level of in-racks be above the second cube but
approximately 15 ft off the floor? It's in a rack supported bldg. with
automated pickers so the machine can't go low enough to use the first
four or five feet from the floor so the space is empty.
Hope you all have a happy new year.
