Be careful though because out this way many of the lesser savvy AHJs are interpreting this to mean that the sprinkler contractor is responsible for proving the building will support the system and so the GCs are learning to specify that in their contracts knowing they'll get backing. Some (both GCs and AHJs) are even trying to require the sprinkler contractor to upgrade the structure if necessary. I have even seen one contract that was trying to pin the soils engineering on the sprinkler guy by requiring he verify that the dirt work, foundations and structure were adequate. Just last week a friend was contractually obligated for $16,000.00 worth of structural upgrades even though not a part of the contract because the AHJ wouldn't release the sprinkler permit until structural calcs were submitted with the plans.
