CAD Draftsman – 2D Fabrication Drawings for Industrial Ducting Systems Anyone

Job Description:
We are seeking an experienced CAD draftsman to prepare detailed 2D workshop fabrication drawings for two industrial ducting systems in a metallurgical processing facility. The systems include:
1. Off-gas ducting system for an aluminum dross processing line
2. Dust extraction/suction ducting system for a hammer mill
The basic plant layout, connection points, and preliminary dimensions will be provided. The scope is to convert this information into complete, fabrication-ready workshop drawings.

Scope of Work:
Develop detailed 2D fabrication drawings (AutoCAD or equivalent) for both duct systems
Prepare general arrangement (GA) drawings showing routing, elevations, and connections
Produce detailed spool drawings with dimensions, joint details, and identification tags
Define duct sizes, transitions, reducers, bends, and branch connections
Include support details (hangers, brackets, supports) suitable for workshop fabrication
Prepare bill of materials (BOM) including plate thickness, flanges, fasteners, and accessories
Indicate welding details, flange standards, and fabrication tolerances
Ensure drawings are suitable for direct use by workshop fabrication team
Revise drawings based on feedback during review cycles

Inputs Provided:
Existing CAD layout showing equipment and connection points
Basic duct routing and preliminary dimensions
Process description and system requirements

Deliverables:
Complete set of 2D CAD drawings (DWG + PDF)
GA drawings for both systems
Detailed fabrication/shop drawings (spools, sections, supports)
Bill of materials (Excel or embedded in drawings)
Revision updates until final approval

Requirements:
Proven experience in industrial ducting or HVAC fabrication drawings
Strong proficiency in AutoCAD (2D)
Experience with dust collection systems, fume/off-gas ducting, or similar industrial applications
Understanding of fabrication practices (sheet metal, welding, flanging)
Ability to interpret process layouts and convert into fabrication drawings
Attention to detail and dimension accuracy

Preferred:
Experience in metallurgical or heavy industrial plants
Familiarity with abrasive dust systems and high-temperature off-gas handling
Knowledge of international standards (SMACNA, ISO, or equivalent)

Project Type:
Short-term / project-based
Remote work acceptable

Additional Notes:
Designer should optimize routing for fabrication and installation practicality
Coordination may be required to ensure no clashes with existing structures read less
