Dimension Checking

Independent verification that fabricated components, assemblies and structures conform to approved drawings and tolerances, using calibrated measurement tools to catch dimensional non-conformities before they reach installation or shipment.

On an assignment the inspector works from the approved drawings and datasheets, checking critical dimensions, nozzle orientations, flange faces and overall geometry with calibrated instruments and recording each result against tolerance. Dimensional verification before shipment is what prevents fit-up problems and rework when components reach the installation site.
