Urgent Industrial Pitched Roof Design

I need a complete pitched-roof layout for an industrial facility and I need it fast. The building’s footprint, column grid, and load data are ready; what’s missing is a sound roof concept that balances structural integrity, drainage, insulation, and ease of fabrication.

Here is what I expect:
• Roof geometry and slopes sized for an industrial span, with attention to snow, wind, and live-load codes in my region (I will share the local code reference once we start).
• Structural member sizing, connection notes, and a concise calculation package that I can forward to the city engineer.
• Drawings in DWG and PDF formats—including framing plan, sections, and critical details—produced in AutoCAD, Revit, or a similar BIM tool.
• A brief material recommendation. I’m leaning toward metal sheeting but I’m open to your guidance on alternatives that suit a pitched configuration.

I’m on a compressed schedule, so please confirm you can deliver a first draft within three days and finalize after one quick revision loop. If you’ve handled large-span pitched roofs before, especially on industrial sites, let me know and share an example sheet. I’ll move fast on awarding once I see the right expertise.
