#SurfsideBuildingCollapse—NEW TONIGHT: your first look of the @NIST investigation underway into what caused a portion of Champlain Towers South to collapse. (THREAD) 📸Courtesy: National Institute of Standards and Technology (NIST)
Here you can see some of the portions of the building that have been preserved and tagged for evidence by engineers with the National Institute of Standards and Technology (NIST) who investigate building failures. 📸: @NIST 
In these pictures @NIST tells us what you are seeing are engineers using ‘nondestructive’ test methods to evaluate the strength and quality of concrete columns. 📸: #NIST
The research laboratory says its collected 200+ elements to include beams, columns, and pieces of concrete slab to “help us determine what we see as the probable collapse mechanism that happened here,” said Christopher Segura, Research Structural Engineer - NIST. 📸: NIST
In a news release NIST also states that it is “in the process of putting together the National Construction Safety Team that will lead the technical investigation”. Background—June 28, 2021 @NIST’s teams of scientists + engineers are modeled after NTSB. local10.com/news/local/202…
