Inspection Documentation, Reporting and Communication

This domain tests whether your records can stand alone as evidence. The exam expects contemporaneous, specific, and traceable documentation that ties each observation to a requirement and a disposition.

Report content

A useful inspection entry identifies the project, date and time, location or tag, specification section, product and batch or lot, measurement tool and calibration status, readings versus acceptance criteria, photographs with scale and location, witnesses, and disposition. Record facts before conclusions. “Joint gap 3/8 in at tag CW-12, joint 4” is evidence; “poor workmanship” is not.

Nonconformance and communication

A nonconformance report should state the requirement, the condition found, the objective evidence, the immediate action, the required corrective action, and the re-inspection result. Hold points are released only by authorized personnel. Verbal directions should be confirmed in writing. Photographs need a scale, tag, and orientation to be useful.

Worked example

An inspector finds 5 of 20 butt joints on a 4-in line with 3/8-in gaps, exceeding the project limit of 1/8 in. The report records the tag, joint numbers, measurements, photo, and specification clause. The inspector issues a nonconformance and places a hold on jacketing. After rework, re-inspection confirms the gaps are within limit, and the nonconformance is closed with date and signature.

Traps that cost marks

Writing conclusions without measurements; using “OK” with no location or reading; submitting reports late; taking photos without scale or tag; accepting contractor assurance instead of verifying; and failing to retain calibration records.
