Smoke Control Special Inspections
Special Inspections for Smoke Control Systems
EB Life Safety provides smoke control special inspections per IBC Section 1705 to verify proper installation and performance of smoke control systems during new construction.
Inspection Evidence
Inspection records should preserve test instruments, locations, readings, observed limitations, responsible corrective trade, and retest status so the final report can be checked against the approved smoke-control basis.
Inspection Scope and Credentials
Smoke-control special inspection should be tied to the approved rational analysis, construction documents, and special-inspection program. EB Life Safety can help define accessible components and interfaces to review, including fans, dampers, shafts, controls, power, doors, and pressure relationships. The building official and AHJ establish required qualifications, forms, frequency, and reporting; a visual observation cannot verify concealed work or every operating condition.
Documenting Installation and Testing
Reports should identify the area and component, reference the approved detail or sequence, record observed conditions and test results, and distinguish a deficiency from an inaccessible or untested item. Testing may involve airflow, pressure, door forces, damper operation, fan status, controls, alarm initiation, elevator response, and emergency power. The applicable code, NFPA 92 guidance, and approved commissioning procedure determine the measurements required.
Resolving Findings Before Acceptance
A deficiency review should connect each finding to a responsible trade and a retest requirement. EB Life Safety can coordinate with the design team, controls contractor, mechanical contractor, and AHJ to clarify the technical basis and update closeout records. The final special-inspection report should accurately state what was observed and tested; it should not mark an unresolved limitation as a pass.
Connecting Special Inspection to Commissioning
Smoke-control inspection is most useful when the special inspector, commissioning team, controls contractor, mechanical contractor, alarm contractor, and AHJ use the same approved sequence. Before testing, the team should verify that sensors, fans, dampers, shafts, doors, power sources, control panels, and communications paths are identified by consistent names. A test script should state the initiating event, expected equipment response, measurement location, acceptance criterion, reset procedure, and record required. Where a component cannot be accessed, a control point is not supervised, or a fan operates but does not achieve the required airflow, the report should identify the limitation or deficiency precisely. Photographs, trend data, calibration information, pressure readings, airflow readings, and control screenshots can support the record when relevant, but they do not replace the approved test procedure. Changes made after a test should be reviewed for effects on the rational analysis and sequence of operations. A failed damper, altered door, revised ceiling, control-program change, or emergency-power issue may require targeted retesting rather than an assumption that the previous result remains valid. EB Life Safety can help reconcile observations with the approved design and coordinate a response package for the AHJ. The final report should distinguish inspection observations, contractor certifications, commissioning results, and AHJ acceptance. This separation makes responsibilities clear and gives the owner a useful maintenance baseline. It also prevents a limited observation from being interpreted as a certification of every concealed component or every future operating condition. The inspection record should identify instruments and calibration status when measurements are relied upon, along with weather or building conditions that could affect a result. A later retest should reference the original finding and state exactly what changed. This preserves a transparent history for the owner and avoids treating a partial retest as a complete system acceptance.

Frequently Asked Questions
What is inspected in smoke-control special inspection?
The scope may include fans, dampers, controls, shafts, doors, power, alarm interfaces, and measurable pressure or airflow performance, based on the approved program.
Can special inspection confirm concealed construction?
Only accessible conditions can be directly observed unless separate documentation or testing supports the conclusion. Limitations should be recorded.
Who accepts the final smoke-control system?
The building official and applicable AHJ accept the system through the required inspection and testing process. The special inspector reports within the approved scope.
