It’s crucial because assessing substantial structural damage involves complex evaluations of the building’s structural integrity. An engineer looks at whether key elements of the lateral force-resisting system are damaged, if the load-carrying capacity of any story has been reduced, and whether the capacity of vertical or snow load-carrying components has significantly diminished. These assessments require detailed calculations and a deep understanding of structural dynamics, which are beyond the scope of most non-professionals. Only a registered design professional can ensure that these evaluations and any subsequent repairs comply with the strict safety and stability standards set by building codes.
