The National Institute of Standards and Technology, a federal agency investigating the collapse, has been monitoring the site's safety.Ĭollins Avenue, which is the major thoroughfare on the barrier island, has been closed to traffic near the site since June 24, when the building partially collapsed, killing at least 97 people. 'We are moving to procure a company to do shoring and bracing of the walls to assure there is no risk,' she said. He has been hired to investigate the cause of the collapse Structural engineer Allyn Kilsheimer submitted a letter to Surfside and Miami Dade officials warning them that the road was not ready to be reopened to traffic. The stretch of Collins Avenue where the site is is less than 0.1miles long. But it's unclear how much of the road may cave if the walls collapse. He recommends building an earthen berm to support the walls near the street and sidewalk. 'If the wall were to collapse or rotate substantially, the retained soil under the street and sidewalk could move with it,' wrote Kilsheimer, of KCE Structural Engineers.

An engineer is warning that the stretch of Collins Avenue next to the collapsed Champlain Towers South building in Miami might also cave in once traffic reopens if more support isn't put in to hold up the walls of the underground parking garage.
