You might talk to a local truss manufacturer and look at flat wood
trusses/ I joists/ etc.that clearspan the entire structure. You
will still need to work out details with a structural man and
contractor(s). In order to clear span, the joists will need to
get deeper which will affect elevations, stairs, etc. This may
still be preferable to a steel beam spanning and carrying a load
with a single post. The open web joists make it fairly easy to
run mechanical systems.
Here is some information:
