Design and construction were decisive, but inspections also failed.
The allegation that maintenance on the Metro could not prevent the collapse of the section on Metro Line 12 because it was caused by hidden design and construction flaws “seems” to make sense but, in the eyes of the company that carried out the independent expert opinion – the one praised and contracted by the government that now repudiates it–, the evidence that the structure presented problems was as “visible” as evidenced by the photographs taken at street level beforehand.
The kick, then, makes no sense, since the supervisors of the Collective Transportation System, if they had done their part, always had the opportunity to detect deformations in the joints of that overpass.
The problem could be detected in routine and extraordinary supervision and maintenance inspections that were simply not carried out or were done poorly, says the third report revealed by El País. “Typical industry practices” (worldwide) in such constructions.
The firm confirmed that there is no record of “repairs made in the sunken section…”.
fuck it
“There are no maintenance or repair records of the concrete or metallic components used in civil engineering that were provided to DNV (…). More detailed inspections should have been carried out by a specialist representing the STC’s civil engineering department in cases of extraordinary events…”, says the expert opinion.
It is obvious that, if the protocol had been complied with, Metro maintenance would not have resolved design and structure problems, but it would have delved into the revisions and warned about the risks, so that the authority would take what was evident very seriously and adopt the necessary measures. that they proceed, including the suspension of the service, as was done during the administration of Miguel Ángel Mancera when the mess that was discovered between tracks, trains and sleepers had to be repaired, at whatever economic and political cost.
The capital’s government underestimates the importance of poor maintenance dragging the main means of transportation in the metropolitan area.
So questionable is its efficiency that Friday’s storm generated waterfalls at the Cuatro Caminos and El Rosario stations, and all for not even worrying about waterproofing when the rains begin.
To the shame of the administration headed by Claudia Sheinbaum are the words of former head Florencia Serranía, who in the face of the tragedy a year ago said “I’m just the director” and in January, in the face of the fire that destroyed the Central Control Post, thus boasted:
“I am the Deputy Director of Maintenance. The Metro has so many problems that I decided to take that double position…”.
The Government of the capital does not, therefore, have the slightest excuse or reason to get rid of its irresponsibility in the deplorable maintenance of the Metro.
