The biggest hurdle that do it yourselfers I have that tendency will
face is that most airport authorities will insist upon a stamped
engineering report designating snow load, wind rating, earthquake
rating, and fire rating..
That pretty much eliminates any homebuilt wood hangars, etc..
My current business venture requires a clear span 60 x 125 foot
building with 30 X 16 door openings at each end... Burning the
midnight oil heavily and getting multiple quotes on everything from
wood truss and I even calculated out for a stick building done by
myself with undocumented workers to slip formed concrete, it came
down to a steel building as the most economical...
