Construction deficiencies behind deadly Mexico City subway collapse, report finds
Mexico City - May 3, 2021

Construction flaws led to the collapse of a Mexico City subway line that killed 26 people and left dozens injured last month, according to the preliminary findings of an independent probe released by the city government on Wednesday.
The investigation, carried out by Norwegian risk management firm DNV, suggests that deficient welding of metal studs, which apparently were not well connected to steel beams supporting a concrete slab and the elevated train rails, was among a number of issues that contributed to the May 4 incident.

A preliminary report into the deadly collapse of a metro overpass in Mexico City last month has found that it was caused by flaws in the construction.
Jesús Esteva, head of the city s public works department, said deficiencies had been found in building materials and structural supports along the line.
More reports will be made in the coming months about the collapse, which happened on 3 May.
The incident killed 26 people and has led to protests in the Mexican capital.
It has also put pressure on allies of President Andrés Manuel López Obrador, and on Mexican billionaire Carlos Slim, Latin America s richest man, whose construction firm Grupo Carso was involved in building the section of train line that collapsed.
