What constitutes a "failure" when verifying items within the durability inspection checklist? In some cases, project teams make design changes prior to the Green Rater visiting the site. In some cases, items are inaccessible and cannot be visually verified. In some cases, strategies are sufficiently vague and hard to verify - e.g. "use very durable lumber for the deck" that the Green Rater does not want to make a subjective judgment about whether the measure was met.
