Correct AutoCAD MEP Drawing Flaws

I have an existing 2D MEP (Mechanical, Electrical, Plumbing) drawing created using AutoCAD, which I need someone to fix before I can proceed with my construction project. The issues I am facing involve:

- Incorrect dimensions
- Missing annotations
- Incomplete symbols
- Problems in electrical panel layout
- Issues in plumbing layout

I'd greatly appreciate if the interested freelancer could update the drawing accurately, ensuring that dimensions are correct, all annotations are added, symbols are complete, and both electrical and plumbing layout are done right.

Ideal Skills:
- Proficiency in AutoCAD
- Experience in MEP drawings
- Attention to detail
- Familiarity with construction codes and standards.

Please only bid if you have relevant expertise and can assure accuracy in the deliverable.
