See the on site plans for several additional areas where sprinkler piping can be covered. Plan modifications showing all changes and job site construction conditionas need to be submitted for review prior to any more cover inspections due to the amount of changes that have occured to the routing of the sprinkler piping. One area of concern is at Remote Area #4 where a branchline has been deleted, upright protection revises, extended coverage pendant added and additional fittings installed in the piping. Per Tim Frost all of the walls in this area, "D", where to be full height but I saw walls that aren't full height. Also several large rooms have swapped from the south side of the building to the north side of the building. I spoke to Scott, the on site fitter forman, about the issues.
