Lock the technical basis
Each supplier should receive the occupancy, module dimensions or clear span, eave height, bay spacing, and the design live load, design dead load, wind speed and ground snow load the buyer can already support. If the seismic design category is unknown, the quotation must say so instead of treating a catalog span as approved.
Primary frame, secondary framing, purlin and girt sizes, insulated metal panel or another enclosure, and the foundation interface belong in the narrative. Thermal transmittance and fire-resistance rating are requested as project targets, not as badges copied from another site.
