I’m about to start excavation on a 40’ x 28’ Shop. It will have a main level with a partial loft and (probably) a full basement. In addition to woodworking I also collect old machinery, which can be heavy.
The floor will be wood for a lot of reasons, including comfort plus I build boats and need to nail down stems, transoms, and jigs, over a basement. The joists are 1 3/4” x 12” LVL’s and have been narrowed to 12” OC. The overall span is 28’ but there will be metal beam on 4 posts in the middle. So 14’ ish b/w support. Perimeter is concrete foundation wall and footers. Floor is 1” plywood (but under consideration for thicker).
This has all been designed by an architect and engineer with my input on equipment inside, up to 2000 lbs in several areas peripherally plus there will be a tool cluster in the middle which might get up to 4000#. I’m told my design is “light industrial” specs.
I would appreciate some other input from folks here, esp those who have similar shops w structural floors, making sure the advice I’ve received is good.
Thx
Jon
