A door combines movement, safety, privacy, acoustics, access control and constant touch. Repeating a weak decision across a project multiplies the problem.
Review the complete assembly
Check leaf, frame, seals, threshold and hardware together. Speech-sensitive rooms require the continuity described in the acoustic budget. Fitting rooms add privacy and accessible operation from the fitting-room test.
Open every leaf on the plan
Test furniture, queues and escape routes. Reception doors interact with the arrival system; service doors must suit back-of-house movement.
Coordinate production and handover
Carry the schedule into shop-drawing review and preserve keys, controls and maintenance records in the operational documentation.
