NIST’s work right now is focused on ensuring that information and evidence related to the June 24, 2021, partial collapse of the Champlain Towers South condominium is identified, collected and preserved, in support of NIST’s technical investigation into the likely cause of the collapse.

Remote Sensing of the Site
NIST staff members are coordinating and leading remote sensing efforts to determine where pieces of evidence were located in the debris pile. They are supported by experts from the Federal Emergency Management Agency (FEMA), Florida State University, the Miami-Dade Fire Rescue Department, the National Science Foundation (NSF), the U.S. Army Corps of Engineers and the U.S. Geological Survey (USGS).
Lidar — which sends out rapid pulses of light and records the reflections to create a type of map — is being used to record the locations of building materials or elements of potential interest and changes to the site as debris is removed. NIST is taking daily high- and low-resolution lidar scans of the site from balconies on adjacent buildings to the north and south of the Champlain Towers South site. Time-lapse cameras are also recording the rapidly changing scene.
Cameras and lidar used by NIST and its partners scan and record the site of the Champlain Towers South condominium.
