| After installation | Installer, elevator contractor, cab supplier or fabricator representative, and site coordinator as needed. | Completeness, alignment, fit, operation, protection, installation workmanship, and damage arising during handling or installation. | Compare with pre-installation condition, assign correction, identify access dependencies, and separate installation damage from supplied-product issues. |
