Mechanical Plant Layout P&ID Drafting

I need a clean, production-ready AutoCAD file of a mechanical plant layout diagram drawn to full P&ID detail. The drawing must show every piece of equipment, pipe run, valve, instrument tag, and utility line so my engineering team can reference it for further calculations and procurement.

You will start from my marked-up sketches and a brief equipment schedule that I will share after award. Scale, layer organisation, and sensible line weights are essential because the file will feed directly into our document control system. Please name layers logically (equipment, piping, instrumentation, text, dimensions, etc.), keep annotation styles consistent, and set the drawing in millimetres.

Deliverables:
• Native AutoCAD .dwg file (latest or 2021 format)
• A plotted, print-ready PDF on A1 sheet size
• A separate legend/key for symbols and line types used

Acceptance criteria:
• All equipment and instruments labelled as per my schedule
• No orphaned layers, blocks, or unused styles
• File opens with no proxy object warnings

If you have recent experience producing P&IDs for manufacturing facilities, this task should be straightforward. Let me know the version of AutoCAD you work in and an estimated turnaround time once you have my sketches.
