Many factors could be responsible for building failure: foundation, soil and building materials. Mr. Dusenberry, whose impressions matched those of several other structural engineers who examined the video, said such a failure would suggest a foundation-related matter potentially corrosion or other damage at a lower level. But he said it was not certain that corrosion was the culprit, and added that you certainly cant rule out a design or construction error that has survived for 40 years.. The concept of progressive collapse of structures was not much known to the engineers before the failure of the Ronan Point Tower. The 2018 report from the consultant, an engineer hired by the condo owners association to examine the building, helped set in motion plans for a $12 million repair project that had been set to start soon more than two and a half years after the building managers were warned about the structural damage. This zone was picked because of its closeness to settlement cracks. When the molasses settled, it was waist-deep and dragged people down. After the collapse, a team from the Occupational Safety and Health Administration (OSHA) came to the site and started an investigation. Excavations for sewers or other utilities should be moved away from existing buildings and should be located so that the excavation cut is outside footing influence lines.
