OP
Well just had my final inspection and passed. Thanks for the assistance.
Now to get the water leaks fixed .
Soon to start on the wooden mezzanine
View attachment 328246
Think I have beat the leaks Seems to water was rolling in as it goes down the straight side wall Because the bottom is chalked and the chalking seems to build a small dam maybe 1/4 high the water can't get out so it flows inside through the rivets and layers of metal in the base plates.
If the next guy building one was to slightly bevel the outside pad base plate area Then a smaller dam would be required .
