Conduct a retrofit firestop condition survey in an existing building

Steps
Scope the survey to the building areas/assemblies of concern (e.g., corridors, shafts, rated demising walls) and coordinate access with building operations before starting.
Physically inspect penetrations and joints against available construction documents, flagging any that lack a documented tested/listed system or EJ.
Photograph and log each condition — location, penetrant type, annular condition, apparent material — to support later system-matching or EJ development.
Prioritize deficiencies by life-safety risk (e.g., open or undocumented penetrations in exit corridors or shafts first) rather than working strictly floor by floor.
Deliver a findings report with recommended remediation systems (or EJ requests) that feeds directly into establishing or updating the building's ongoing barrier-management program.
Known gotchas
Existing conditions often predate current listings/products, so exact tested-system matches may not exist — budget for engineering judgments on a meaningful share of retrofit findings rather than assuming every gap has an off-the-shelf listed fix.
A retrofit survey is a point-in-time snapshot — without feeding into an ongoing barrier-management program, the findings go stale as soon as new trade work reopens penetrations.
Confirm whether local code enforcement treats retrofit remediation as new construction (triggering current-code special inspection) or as maintenance repair, since that affects which inspection standard applies.
