I did a pole construction about 10 years ago. 24'x30'x11' building. Snow load was 54" and wind was 120 mph, as per Boulder County. I laughed but the specs are not out of line.

Double/triple check the measurements before ordering. If you know a PB builder, show them the plans.

I did fiber mesh re-enforced concrete floor. Not bad but their are cracks. The floor went in after the building was up. 2x12 pressure treated at the bottom level to hols in the concrete.

Too many details to put in one post. I can answer questions...
