For Part 3 Air Filtration Maintenance under Feature 05, which documentation is required?

• A. Operations schedule
• B. LOA from MEP Engineer
• C. Spot Check
• D. Permit

Answer: (A)

Regular maintenance of air filtration depends on a clear plan that shows when tasks are done and who is responsible. For Part 3 Air Filtration Maintenance under this feature, the required documentation is an Operations schedule. This schedule lays out all planned filtration maintenance activities, their frequencies (like inspections, replacements, or cleanings), the personnel responsible, and any procedures to follow. Having this documented plan ensures maintenance happens consistently and on time, which supports sustained indoor air quality and the system’s performance.

A letter of authorization from the MEP engineer is a design coordination artifact rather than ongoing maintenance documentation. Spot checks are useful but are individual verifications and don’t provide the comprehensive, forward-looking schedule required. Permits relate to approvals and compliance, not the routine maintenance record.
