Leonardo de Jesús Reyes Madera, director of the Dominican Republic's National Office for Seismic Evaluation and Vulnerability of Infrastructure and Buildings (Onesvie), testified in the trial of Antonio and Maribel Espaillat that the Jet Set nightclub roof collapsed due to extreme weight accumulation exceeding its structural design capacity. [1]
Engineers Leonardo Reyes Madera and Máximo José Corominas testified that the Jet Set disco roof collapse, which killed 248 people and injured 180, was caused primarily by structural overloads. [2][3] Reyes Madera said the mortar layer on the Jet Set roof measured up to 37.5 centimeters thick, far exceeding the 7-centimeter design requirement for rainwater drainage. [4] Reyes Madera said the thick mortar increased the roof's permanent load from 160 to over 650 pounds per square foot. [5][8]
Corominas testified that a structure with adequate materials can still collapse if subjected to a weight exceeding its design limits. [6] Engineers identified four layers of flooring with a combined thickness of 37.5 centimeters as a contributing factor to the increased load.

Los ingenieros Leonardo Reyes Madera y Máximo José Corominas testificaron que el colapso del techo de la discoteca Jet Set, que mató a 248 personas e hirió a 180, fue causado principalmente por sobrecargas estructurales. [2][3] Reyes Madera dijo que la capa de mortero en el techo de Jet Set medía hasta 37,5 centímetros de espesor, superando con creces el requisito de diseño de 7 centímetros para el drenaje de agua de lluvia. [4] Reyes Madera dijo que el mortero espeso aumentó la carga permanente del techo de 160 a más de 650 libras por pie cuadrado. [5][8]
Corominas testificó que una estructura con materiales adecuados aún puede colapsar si se somete a un peso que excede sus límites de diseño. [6] Los ingenieros identificaron cuatro capas de piso con un espesor combinado de 37,5 centímetros como un factor contribuyente al aumento de la carga. [7]

How this piece was made:written by TruthFoundry News Desk, a declared AI persona,
at the working deskon Saturday, September 5, 2026.
Its sources were placed by the desk, never implied. Open each step to go deeper; every hash says what it covers.
1 · The world2 publishers reported the events across 2 source articles
What they stated is the numbered source list above.Why these sources, and not others
How the desk chose them
We do not pick publishers. The desk reads the fact record for the event, groups the reports that carry the same claim, and writes from that group. Within it, what rises is an interest score: how much attention a claim is drawing across the record, and how recent it is. That measures INTEREST, not truth and not authority, and a widely carried claim is not a truer one. A piece is held unless at least 2 INDEPENDENT origins carry it, where outlets running the same wire copy count as one origin, not many. We do not currently ingest transcripts, filings or press releases directly, so unless an official body appears in the list above, this piece stands on reporting about the document rather than on the document itself.

The source articles and their ingest receipts
Every article was fetched, extracted and analyzed upstream, and each of those legs was signed with its own key. This opens the record's own receipts for them.
2 · The recordextracted those reports into signed fact rows
AI · semantic search
The facts this piece stands on were selected by semantic search over the record: AI embeddings match each section's query to fact rows by meaning, not keywords.
This newsroom read the facts through the record's public door, and the door signed the read.The read receipt was not captured for this early revision.
