Point being, read the contract and the specs very carefully. There is much ignorance in the AE realm on what the sprinkler contractor is to do. Sometimes it's not all ignorance but just some unsavory persons looking for a stooge on which to hang the undesirable or forgotten work.

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.
