The Government of Mexico City announced that 21 cracks were detected in the metallic structures of the elevated viaduct of the Line 12 of the Collective Transport System (STC) Metro; The search for new fissures began after the results of the expert opinion produced by the CDMX Attorney General’s Office (FGJCDMX) were released.

According to what he commented at the press conference Rodrigo González, specialist from the University of Nuevo León, the new discoveries were found during the review of the progress of the reconstruction of the work between the Tezonco, Olivos and Nopalera stations.

So far, it has been reported that progress has been made in a 28.5% in development of the initial inspection of the welds of the reinforced beams, which was ordered by the Technical Advisory Committee (headed by the head of the Ministry of Works and Services, Jesús Esteva Medina) last August.

Also, González stated that the inspection was carried out at random points, although special interest was fixed on those prone to fatigue, that is, where cracks generated by induced distortion were observed, because this was one of the possible causes of the collapse of the elevated section on the night of May 3, according to the two expert opinions that were carried out.

“At the time, the entire section was inspected by the College of Civil Engineers and this was not detected. In a regular inspection it is impossible to detect. It is a detailed inspection based on the results of the expert opinion and the request of the technical advisory committee, so this will be taken into account for the reinforcement project “
