DG Set Soundproof Canopy Drawings

I need a complete set of fabrication-ready drawings for a diesel generator canopy whose main function is soundproofing. The enclosure will be built entirely from steel, so every detail—from structural members and weld symbols to the arrangement of acoustic panels and ventilation louvers—has to reflect that choice of material. My goal is to hand your package straight to the fabricator without additional rework. That means: • Fully dimensioned 2D shop drawings in DWG and PDF • A concise bill of materials with steel grades and thicknesses • Section views showing acoustic lining, doors, hinges, lifting eyes, cable-entry plates and exhaust routing • Notes on surface treatment, fasteners and gasket specifications • A 3D model (STEP or similar) for quick visual checks • Up to two design revisions after my first review Use any mainstream CAD platform—AutoCAD, SolidWorks or Inventor are all fine—as long as exported files open cleanly. If you have experience meeting CPCB, ISO or similar acoustic guidelines, let me know; I have not locked down a target decibel level and will welcome your recommendations. Timeline is flexible but I would like an initial draft within a week so we can keep the project moving.
