Facing this collapsed corner, he remembered that he had first heard some kind of detonation that had shaken the eighth floor of the Artz Pedregal office, where he was working as a capturer. In less than 30 minutes, the collapse of this corner has flown.
It was almost 10:40 in the morning. I heard a roar. I felt how the building has changed. About half an hour later, there was a crack and there was another stronger movement. We thought it was a hectic tremor. People from the civil protection of the building expelled us, "said the 35-year-old man
. At 08:00 hours, the first to arrive were over a hundred masons who finished and worked in nearby premises. One of them called Alejandro and arrived 20 days ago from Jalapa, Veracruz. He was at the back of this bend which collapsed in a few seconds.
We were working at the back end. We were scared We were like 50. We heard that like an explosion and we started running. "
Construction personnel commented that the structure could be decomposed by weight, since they had counted six concrete columns and at least three other cross beams
After the arrival of the secretary of Civil Protection It was reported that the affected area was 700 square meters.Two dog-human police binomans of the capital visited the area to confirm that there had been no people buried.

We are concerned about the construction process and the guarantees to continue working there because the work was not done well. When a you nnel was formed here, they never built a wall to contain the Periferico's structure. On the border side, the owners and authorities told us that our fence had no problem. We do not have a retaining wall and the biggest weight of the square is the one that borders the condominium, "said Maricela Silva, who announced that she would ask for a serious opinion.
