They are storing empty tin cans on pallets. (Primarily empty # 10 cans) Each pallet load is eight foot high. Then three loads stacked. The problem with this building is that it has an existing wet sprinkler system that was installed during the 60's. The building is a little over 23,000sqft. The owner would like to turn the system into a dry b/c of the heat bill during the winter months being over $10,000.00 a month. Have not been able to figure out what the original design intent, but the pipe sizing is out of control. Lots of 10", 8", 5" and of course some 3 1/2". System would need to be split. Currently as one system would have a volume of over 2,100 gal.
