(b) [F21-OS3.1]Applies to floors and elements that support floors.


Intent 1:

To limit the probability that weathering of pyritic material will lead to excessive loading on foundation walls, under lateral soil pressure, with attendant structural damage to the foundation and superstructure.

For floors and elements supporting floors, this is to limit the probability of excessive deflection or damage, which could lead to rough or uneven floor surfaces, which could lead to persons tripping or falling, which could lead to harm to persons.
