The National Institute of Standards and Technology (NIST) released its final investigative report on June 23, 2026, confirming that Champlain Towers South in Surfside, Florida, exhibited signs of structural failure for nearly three weeks before its catastrophic collapse on June 24, 2021, which claimed 98 lives. The report found that two connections between garage columns and the pool deck began failing in early June 2021, with visible cracking, water infiltration, and a detached pool-deck section hours before the collapse.
NIST determined that the building's structural inadequacy was present from construction, with design providing less than half of required code-level strength in some areas. Forty years of salt-air corrosion, water intrusion, and deferred maintenance compounded these deficiencies until the structure had no margin left.
Estructura, a structural intelligence company headquartered in San Juan, Puerto Rico, with offices in Miami and Lima, argues that this tragedy underscores the necessity of continuous, AI-powered structural monitoring. The company deploys a vertically integrated combination of GeoSIG precision ground sensors, the GeoSMART AI-based software platform, and TerraIntel satellite InSAR imaging, which detects millimeter-scale ground deformation.
Applied to Champlain Towers South, this system would have produced alerts weeks before the collapse. TerraIntel's satellite imaging would have tracked differential subsidence of the pool deck slab, while GeoSIG sensors would have registered anomalous micro-vibrations and deflection patterns. GeoSMART's AI would have flagged these anomalies and triggered early warnings, giving building managers and residents time to act.
Estructura emphasizes that design flaws and construction deficiencies represent only one of four risk categories that can lead to failure. The others include wear, aging, and deferred maintenance; seismic events; and extreme climate events. The company's platform is designed to detect structural signatures from all these risks.
Founded as a division of Dorado Services, a U.S. engineering firm and federal contractor to the Army Corps of Engineers and FEMA since 1999, Estructura integrates GeoSIG and TerraIntel technologies. The system is deployable in any structure type across the Americas, serving high-rises, bridges, hospitals, and more. The company reports that clients typically recover their monitoring investment within one to two years through predictive maintenance savings, disaster mitigation, reduced insurance premiums, and enhanced property value.
"A reserve fund is only useful if you know what you need to repair, and when," said Julio Miranda, Estructura Vice President and co-founder. "The Surfside building gave weeks of warning that no one had the technology to read. Every building owner and manager in a coastal city, a seismic zone, or a hurricane corridor should ask themselves the same question: if my building were failing right now, would I know?"
