Final fire sprinkler inspection passed/complete

I stopped the rough-in inspection due to the installation not matching the approved plans. Branchlines have been added and several of the branchlines are not in the same location as the plans show them. It appears that the upright sprinkler heads have been hydraulically calculated and are shown placed directly on the branchlines. However they are actually installed on 1" armovers which changes the hydraulic calculations. I noted that there are additional fittings on the 4" main and the 2" branchlines. A low point drain will be needed as discussed. Plans will need to be resubmitted with all changes and revised hydraulic calculations.
