The prop►ose� prof ect is a professivnal counseling clinic to be constructed in
Rexburg City for Randy yardman and Myrle Hansen. construction of the
foundation and footings will be standard reinforced concrete. Upper walls
will be light framed mood construction. The floor will be framed with wood
I -joists. The roof system will be manufactured trusses with the exception of
the entry way which will have a heavy limber truss
