An engineer who was hired by Surfside, Florida, to analyze last month's residential building collapse said he was denied access to the site because police agencies are investigating the scene.
"Until they do their job, we can't go in to do samples of materials and take those samples and test them to understand what the various components of the building that came down was," structural engineer Allyn Kilsheimer told CNN's Ana Cabrera on Friday.
"What I'd like to have the access to first is the basement slab of the building, to go in there to do the exploratory testing of the ground, the power foundations and all that stuff to understand," he added.
