Overdue Crane Inspection and Untagged Rigging Before a Critical Pick
An erector needs a 200-ton crawler crane for a critical pick in five days. The crane's annual third-party inspection was due 45 days ago, and the inspector cannot come for three weeks. Rigging inventory shows 12 slings, three with illegible tags, and two shackles with no inspection record. The torque wrench used for bolt verification was calibrated 60 days beyond its due date, and the project requires verification of 5 percent of bolts. In the laydown yard, galvanized members are stored on the ground without dunnage and show white rust; anchor bolts are stored in an unmarked area shared with rebar. About 40 percent of the yard is usable.
1. Rank the release-to-service decisions for the crane, rigging, torque wrench and stored material. Explain the ranking criterion you used.
Read the worked answer
Rank by consequence if the item fails in service and by whether the condition is detectable after the fact.
- Crane - do not release for the critical pick. An overdue annual inspection is a known regulatory and safety noncompliance, and a critical pick has the highest consequence. The item cannot be made acceptable by a visual check from the operator; it needs the inspection.
- Rigging - do not release the three untagged slings or the two unrecorded shackles. Remove them from the jobsite or quarantine them with red tags. Untagged rigging has unknown capacity and history, and slings fail without warning.
- Torque wrench - do not use for verification until recalibrated or replaced. The 5 percent verification loses meaning if the instrument's error is unknown. This is a quality nonconformance, not an immediate life-safety issue.
- Stored material - hold and inspect. White rust on galvanized members and an unmarked anchor bolt area are corrosion and misidentification risks. They are correctable before erection and do not stop the pick.
The criterion is severity times irreversibility: crane and rigging failures injure people; tool calibration and storage failures produce latent defects that can be corrected before installation.
2. State the compensating measures you would accept for each item and identify what cannot be waived.
Read the worked answer
Compensating measures must reduce risk without pretending the noncompliance is resolved.
- Crane: bring the third-party inspector forward by paying for a call-out, or rent a crane with a current inspection. If neither is possible, re-sequence so the critical pick moves after the inspection date. A documented operator walk-around is not a substitute for the annual inspection.
- Rigging: destroy or return the untagged slings; do not use them for any lift. For the two shackles, either find the inspection records or have them inspected and tagged by a competent person before use. Buying replacements is usually cheaper than the paperwork.
- Torque wrench: send it for recalibration or use a calibrated backup. If neither is available, the verification cannot be performed by torque method; get the engineer's approval for an alternative method rather than guessing.
- Stored material: move galvanized members onto dunnage, separate anchor bolts into a marked area, and inspect for corrosion. Reject or re-protect as required.
What cannot be waived: the crane's annual inspection, tagged and inspected rigging, and a calibrated instrument for the specified verification. Schedule pressure does not change those, and a waiver would convert a detectable problem into an undocumented one.
3. Describe how you would document these decisions so that the record supports both the project and a certification audit.
Read the worked answer
The record has to show what was found, what was decided, who decided and what happened next. One equipment release log per item works better than scattered emails:
- Crane: inspection due date, current status, the decision not to release, the alternative chosen, and the new inspection date when it happens. Attach the inspector's report and the revised lift schedule.
- Rigging: inventory list with tag numbers, the three slings and two shackles flagged, red-tag photos, and disposal or inspection records. Note who removed them from service.
- Torque wrench: calibration certificate with the due date, the out-of-calibration finding, the recalibration or replacement record, and the serial number used for the 5 percent verification.
- Material: receiving inspection report, photos of white rust, the dunnage correction, and the marked anchor bolt storage area.
For a certification audit, the important part is the traceability: a finding, a disposition, an owner and a closure date. The log also becomes the evidence that the quality system detected and controlled the problem rather than the auditor finding it first.
