Sentence 9.23.15.4.(1)

Intent 1:

To limit the probability of inappropriate orientation of or aligned joints in plywood subflooring, which could lead to inadequate strength between joists, which could lead to an inability to resist expected gravity loads, which could lead to:

• sagging or cracking of flexible or brittle finished floor between floor joists.

This is to limit the probability of an uneven walking surface, which could lead to persons tripping or falling, which could lead to harm to persons.
