AutoCAD Model Correction

I need an AutoCAD drawing corrected. The base model space is messed up, with misalignment of components on different elevations.

Key Requirements:
- Correct Z-axis misalignments
- Ensure all layers (Foundation, Walls, Ceiling) have accurate information
- Maintain adherence to company standards
- Paper space layouts need to function correctly

Ideal Skills and Experience:
- Proficiency in AutoCAD
- Experience in correcting complex drawings
- Familiarity with company standards in CAD
- Strong attention to detail and accuracy

Redrawing might be necessary, but layers must have correct information.
