3D Service Model on Revit

I need help creating a 3D sectional service model on Revit for presentation purposes. The model should depict the bathroom and service-duct portions, showing the relationships between:

- Sanitary fittings
- Water supply
- Drainage pipes
- Service enclosures (ducts)
- Surrounding construction

I have the full building already modeled in Revit; you just need to add the systems. A medium level of detail is required.

Ideal skills and experience:
- Proficiency in Revit
- Experience with 3D modeling and service integration
- Attention to detail and accuracy
- Ability to work with existing models

Looking for someone who can deliver accurately and efficiently.
