Leonardo de Jesus Reyes Madera of the National Office for Seismic Assessment and Infrastructure and Building Vulnerabilities (Onesvie) said that the final technical report prepared by his office on the collapse of the roof of the JetSet Club in Santo Domingo would be made available this week. During an interview on Esta Noche con Mariasela, he said the conclusions in the final report are the same as in the preliminary report that was released in June 2025. The preliminary report had revealed that the overload of the roof had caused the 8 April 2025 tragedy. At least 236 persons died in the tragedy.
The final report includes the technical simulation that recreates the collapse.
The preliminary report was prepared by Leonardo de Jesus Reyes Madera, and Maximo Jose Corominas Quezada (Presoled SRL) and California-based Eduardo A. Fierro (BFP Engineers). The three are forensic engineers. Maximo Jose Corominas is the son of engineer Rafael Corominas Pepin, regarded as the father of seismic preventive engineering in the Dominican Republic.
The report establishes that the edifice was originally built in 1973 to house a movie house. The report mentions changes to the building for its operation as a nightclub. The report points to excessive loads exceeding the structural capacity of the roof’s support elements as the primary cause. The weight placed upon the collapsed roof far surpassed the safety thresholds designed to ensure its stability. This overload ultimately compromised the structural integrity of the components responsible for maintaining the roof’s security, leading to its failure.
The preliminary report was delivered to adjunct prosecutor Wilson Camacho on 11 June 2025.
