Mexico’s richest man has pledged to rebuild and pay for a segment of a Mexico City subway line that collapsed on May, killing 26 people, President Andrés Manuel López Obrador said Wednesday. López Obrador said telecom and construction magnate Carlos Slim has promised to pay for the rebuilding out of his own pocket and have it back in service in a year. One of his companies had originally built much of the section where the collapse occurred.
One of Slim’s companies largely built the troubled section of the Line 12 subway. Slim has denied there were construction defects, but a study by an outside certification company cited poor welds in studs that joined steel support beams to a concrete layer supporting the track bed. The city government hired Norwegian certification firm DNV to study the possible causes of the May 3 accident, in which a span of the elevated line buckled to the ground, dragging down two subway cars. The report said there were apparently not enough studs, and the concrete poured over them may have been defective; the welds between stretches of steel beams also appear to have been badly done. The existence of construction defects when the line was built between 2010 and 2012 could be a major blow to Slim and to the political career of Mexico’s top diplomat, Marcelo Ebrard, who was mayor at the time. Another round of studies is to be carried out, and a criminal investigation has not yet resulted in any charges.
The collapse was also embarrassing for Slim, currently Mexico’s richest man and once the world’s wealthiest. Slim is an engineer by training and his firms are currently involved in building some parts of the controversial Maya Train project, which will circle the Yucatan Peninsula.
