Mechanical Rough-In Inspection Checklist
Here’s a Mechanical Rough-In Inspection Checklist that can be used in eAuditor Audits & Inspections for residential or commercial projects. This checklist will help inspectors ensure that mechanical systems such as HVAC (Heating, Ventilation, and Air Conditioning), ductwork, and other related installations comply with plans, safety standards, and building codes.

How to Use in eAuditor Audits & Inspections
- Create a New Template: Open eAuditor Audits & Inspections, go to “Templates,” and click “Create New Template.”
- Add Checklist Sections: Organize the template into sections like “General Information,” “Ductwork Installation,” etc.
- Input Fields: Use appropriate fields (text input, checkboxes, multiple choice, etc.) for each item.
- Attachments: Allow for photo documentation in sections where needed (e.g., ductwork installation).
- Scoring (Optional): Apply a pass/fail or score-based system if needed to evaluate each section.
- Automated Reminders: Set reminders for re-inspections or follow-up on flagged items.
This checklist ensures that all critical aspects of mechanical system rough-ins are checked thoroughly, ensuring code compliance and functional integrity during the construction phase.
