What's inside this template
Project Documentation and IAQ Plan
-
Approved IAQ management plan is available on site
Confirm the current construction IAQ plan is accessible and matches the project scope.
-
Roles and responsibilities are assigned
Verify that the contractor, subcontractors, and site management responsibilities are defined for IAQ controls.
-
Material submittals and SDS are maintained
Check that product submittals, safety data sheets, and low-emitting material records are organized and current.
-
IAQ inspection log is up to date
Confirm routine inspections, corrective actions, and follow-up items are documented.
Source Control and Material Protection
-
Dust-generating activities are isolated or controlled
Verify cutting, sanding, grinding, and demolition areas are separated and managed to prevent spread of contaminants.
-
Low-emitting materials are stored properly
Check that adhesives, sealants, paints, and other materials are stored in sealed containers and protected from contamination.
-
Moisture-damaged materials are removed or isolated
Confirm wet, mold-affected, or visibly damaged materials are not installed and are segregated for disposal or remediation.
-
Combustion sources and fumes are controlled
Verify temporary heaters, generators, and fuel-powered equipment are managed to minimize indoor exhaust exposure.
-
Contaminant-generating work is scheduled appropriately
Check whether high-pollution activities are sequenced to reduce exposure to finished or occupied areas.
HVAC Protection and Ventilation
-
HVAC equipment is protected from construction debris
Confirm air handling units, coils, filters, and return openings are covered or isolated during construction activities.
-
Duct openings are sealed when not in use
Check that supply and return ducts are capped, sealed, or otherwise protected from contamination.
-
Temporary filtration is installed and maintained
Verify filters are installed at appropriate stages and replaced when loaded with dust or debris.
-
Outdoor air intakes are protected
Confirm intakes are not exposed to construction dust, exhaust, or other airborne contaminants.
-
Ventilation system operation follows the IAQ plan
Check that system startup, shutdown, and purge procedures align with the approved construction IAQ plan.
Housekeeping and Waste Management
-
Work areas are free of excessive dust and debris
Inspect floors, surfaces, and hidden areas for accumulated dust, sawdust, and construction waste.
-
Waste is removed regularly from the work area
Confirm trash, scrap materials, and contaminated waste are collected and disposed of on a routine schedule.
-
Wet cleaning methods are used where appropriate
Verify damp wiping, HEPA vacuuming, or other dust-control cleaning methods are used instead of dry sweeping when needed.
-
Housekeeping supplies and equipment are available
Check that vacuums, cleaning cloths, and other housekeeping tools are present and suitable for IAQ-sensitive work.
-
Waste containers are covered and managed properly
Confirm dumpsters, bins, and interior waste containers are controlled to prevent dust migration and odors.
Flush-Out Readiness and Closeout
-
All construction dust-producing work is complete
Confirm that major dust-generating activities are finished before flush-out or final IAQ verification begins.
-
HVAC system has been cleaned and prepared for flush-out
Verify filters, coils, ducts, and accessible components have been cleaned or serviced as required.
-
Flush-out schedule and ventilation rates are documented
Check that the planned flush-out duration, airflow rates, and operating conditions are recorded.
-
Final IAQ testing or verification plan is available
Confirm the project has a documented plan for final air quality testing, if required by the owner or certification program.
Common use cases
Frequently asked questions
Who should use this IAQ audit template?
It is designed for contractors, site supervisors, and quality teams responsible for construction-phase indoor air quality. Use it to confirm the project is following the approved IAQ plan and closeout requirements.
What does this audit help verify?
It checks source control, material protection, HVAC safeguarding, housekeeping, and flush-out readiness. That helps reduce dust migration, protect equipment, and document compliance before turnover.
Can this template be used during active construction?
Yes. It works well as a recurring field inspection during active work and again near closeout. Regular use helps catch issues early, before they affect finishes, ventilation, or final testing.
Does this template support HVAC and duct protection checks?
Yes. It includes items for sealing duct openings, maintaining temporary filtration, protecting outdoor air intakes, and confirming ventilation follows the IAQ plan. Those checks help prevent contamination of the building system.
Is this suitable for final closeout and flush-out planning?
Yes. The last section is focused on flush-out readiness, including completion of dust-producing work, HVAC cleaning, documented ventilation rates, and final IAQ verification. It helps teams confirm the site is ready for the next phase.
