It is always exciting to see people get new buildings, which solve their problems.
I am impressed your builder selected glu-laminated columns for your building, they are a superior product.
Some things which amaze/surprise me:
Why it is builders persist in placing posts every 8'? Considering steel roofing and siding comes in multiples of 3' neither 32' or 56' results in an even number of steel panels per wall. More work for the builders, and a small, but unneeded waste of material which the building owner ends up paying for.
Also (with 8' column spacing), the wall girts as installed, do not meet with the requirements of the Building Codes:
Them Girts, They Be a Bending
Unless there is a tricky access to the large overhead door, paying the huge premium for a 14' wide door, rather than the more standard 12' wide is something I do not understand either. For the cost of 14', one might as well pay the few extra dollars and go with 16' wide, which at least would allow for two cars to enter side-by-side.
