SURFSIDE (CBSMiami/AP) — An engineer hired to help figure out why Surfside’s Champlain Towers South collapsed, killing at least 97 people, is now warning officials that it still might not be safe enough to reopen Collins Avenue, where it runs next to the site of the collapsed condo.
Structural engineer Allyn Kilsheimer warned officials in a letter on Thursday that Collins Avenue could crumble, according to CBSNews partner The Miami Herald.READ MORE: Wednesday Arrives With Stormy Weather And The Start Of Fall
All that remains of the Champlain building are the walls of the underground parking garage, around a hollowed-out foundation, and Kilsheimer says that without more support for those walls, traffic could make them collapse, with parts of the street falling into the void.
“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.
He recommends building an earthen berm to support the walls near the street and sidewalk. Otherwise, the movement “could cause portions of the street to collapse and could seriously compromise the utilities under the street,” he wrote.
Miami-Dade County is bringing in crews to help shore up the remaining underground walls, Rachel Johnson, the county’s communications director, told the Herald.READ MORE: Traffic Alert: Expect Delays On I-95 NB Near Ives Dairy Rd Due To a Fatal Crash
“We are moving to procure a company to do shoring and bracing of the walls to assure there is no risk,” she said.
The National Institute of Standards and Technology, a federal agency investigating the collapse, has been monitoring the site’s safety.
Collins 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. Town officials had said Collins Avenue would be opening soon.
In the letter, Kilsheimer said heavy rain would increase the risks substantially.MORE NEWS: 'Downtown Miami's Largest Office Party' Returns Thursday As Corporate Run Kicks Off From Bayfront Park
