Final answer:
To determine if a flooded building is substantially damaged, inspections of the foundation, walls, roof, and electrical system are essential to assess potential structural issues and safety hazards.
Step-by-step explanation:
When inspecting a flooded building to determine if the structure is substantially damaged, it is important to check several crucial aspects of the building. These include the foundation, walls, roof, and electrical system. The foundation must be examined for cracks or shifts that could compromise the building's stability. The walls should be checked for water damage, structural integrity, and the presence of mold. The roof needs to be inspected for leaks, missing shingles, or other signs of potential failure. Lastly, the electrical system must be thoroughly evaluated for water damage as this can pose significant safety hazards.
