Double-Sided Metal Billboard Design

I’m ready to commission complete construction drawings for a double-sided metal billboard intended for outdoor advertising. I already have the exact overall dimensions and placement constraints, so you will be working from firm size data rather than loose concepts.

Here’s what I need from you:

• Detailed structural drawings (plan, elevation, sections, connection details) that a fabricator can follow without guesswork.
• Calculations or clear notes that justify member sizing, wind load resistance, and footing requirements, compliant with standard outdoor advertising codes.
• Editable CAD files—DWG or similar—plus a print-ready PDF set.

You’re free to choose the drafting platform (AutoCAD, Revit, SolidWorks, etc.), but the final files must remain fully editable. The focus is strength and longevity: galvanized steel members, welded or bolted connections, service ladder and catwalk accommodations, and a maintenance-friendly access hatch between faces.

Once I supply the site’s wind zone rating, soil bearing capacity, and my dimension sheet, I’d like you to confirm any remaining data you need, then deliver a first pass for review. After one coordinated revision round, the package should be ready for engineer stamping on my end.

If you have prior billboard or large sign structure experience, please highlight it when you respond, and include an example sheet if possible. I’m looking forward to a smooth, well-documented design process.
