NEC defines defects as part of the works that is not in accordance with the Scope.
What is Patent defects?
Defect that can be discovered by a reasonable inspection e.g. crack in the wall
What are latent defects

Why is the defect correction period typically 12 months?
As it allows the building to go through all the 4 seasons throughout the year, giving time for most defects except latent to become apparent
