See the city approved plans for locations where piping is ok to cover above the remaining hardlid areas. The exterior canopies are ok to cover except where shown on the plans. This is due to the pipe sizes installed not matching what is shown on the plans. The fire sprinkler contractor did not show the pipe size on the piping in question on the north canopy. Since the fire sprinkler contractor did not provide the pipe sizing and center to center length I had to look at the hydraulic calculations to verify this pipe size. The calculstions state the piping between nodes 12 and 87 to be 2". The fire sprinkler contractor has installed both 2" and 1 1/2" pipe between these two node points. The exterior piping in the west canopy is installed as 2 1/2" but is shown as 2" on the plans. Again installation does not match the city approved plans. I also noted many locations where electrical wiring has been attached to the sprinkler piping and to the all thread rods. The fire sprinkler contractor needs to resubmit correct as-built plans or install this project per approved plans. Also there were locations that the sprinkler plans show pendant sprinklers but per the general contractor there will be no ceilings and only the structure above. These changes shall also be shown on a corrected set of city approved as-builts.
