ATC-20 (Rapid Evaluation of Buildings)

ATC-20, or Rapid Evaluation of Buildings, is a standardized method used by trained professionals to quickly assess a building’s safety after a disaster, such as an earthquake or hurricane. It involves inspecting structures for visible damage, such as cracks, deformed elements, or instability, and assigning safety categories. The goal is to identify buildings that are safe to occupy, need repairs, or are unsafe and should be avoided. This process helps emergency responders, engineers, and the public make informed decisions about shelter, safety, and necessary repairs in the aftermath of a disaster.
