The call, up front. Five years on, the Surfside collapse hasn’t changed the core method: aging towers are still judged by point-in-time visual inspections that miss what they can’t see. The final findings from NIST (the US federal standards agency) are the proof: the failure began about three weeks before the collapse, as connections failed and the load shifted onto the parts still holding, exactly the slow degradation a periodic snapshot can’t catch. The gap isn’t awareness or even code (the building rules). It’s continuous structural data on buildings that have none.
The gap
Concrete and rebar (the steel bars inside concrete) degrade continuously; a visual inspection only checks now and then. As-built documentation (the original records of what was actually built) is thin, so inspectors reconstruct history instead of reading live performance. The real blocker is the absence of a real-time structural signal, not the codes, which are already moving toward mandatory recertification.
Codes are catching up; sensing isn't. The opportunity is the retrofit-grade monitoring layer (sensors fitted to buildings that already stand) that turns recertification from a once-a-decade snapshot into a live feed.

The move
The buyer is the building owner facing a recertification deadline and an insurer pricing the unknown. Sell retrofit-grade continuous monitoring that converts a once-a-decade visual audit into a live structural feed, before the next collapse writes the mandate for you.
