Equipment and Facilities
The right tool, maintained and proven
Certification examiners expect a system for selecting, inspecting, maintaining, and calibrating equipment that affects erection quality. Production equipment includes cranes, rigging, manlifts, welding machines, bolting tools, and compressors; measuring and test equipment includes torque wrenches, tension calibrators, levels, transits, and weld gauges. Facilities include laydown yards, storage racks, fabrication areas, and environmental protection for materials. Equipment must be suitable for the task and checked before use; measuring devices used for acceptance decisions must be calibrated at defined intervals with traceability to a recognized standard. Records should show identity, interval, result, and action taken when out of tolerance.
Traps: confusing maintenance with calibration. A crane with a current oil-change log is not thereby a calibrated measuring device; a torque wrench with a calibration sticker is not thereby inspected for damage. Another trap is assuming rented or subcontractor-owned equipment is exempt-if it is used for acceptance work, it needs verification. Reviewers also look for what happens when equipment fails calibration: the impact on work already accepted must be assessed.
Rule of thumb: separate the register into "production" and "measuring/test," and give each item a unique ID, owner, interval, and status. Worked example: a torque wrench used to verify bolt tension is found out of calibration. The company quarantines it, reviews connections tightened since the last good calibration, retests a sample, and documents disposition. That response demonstrates control; merely replacing the wrench does not.
