Red Seal Ironworker (Structural/Ornamental) cheat sheet

Establish the current view, revision, datum, units, and included allowances.

Do not scale an NTS sketch when an explicit dimension is provided.

Distinguish signed coordinates from offsets and centre dimensions from clear gaps.

Level transfer uses benchmark plus backsight minus foresight.

Count circular positions and straight first-to-last intervals on the correct basis.

Check mirrored geometry, cumulative alignment, and measured temperature conditions.

Use suitable tools and compatible gas-system components rather than physical fit alone.

Coordinate access, hot work, and simultaneous work interfaces.

Determine the complete suspended assembly and its mass distribution.

Find static reactions by moment balance when the load is not centred.

Use the actual hitch, angle, orientation, and component ratings.

A vertical component is tension times the stated sine, cosine, or component factor.

Account for chart sector, loaded radius, accessories, and permitted interpolation rules.

Average pressure uses effective supported area, not necessarily the full mat outline.

Control blind-lift communication, signaller handover, and control-line paths.

Document post-lift damage and maintain approved crane assembly and disassembly support sequences.

A future diaphragm or final load table does not establish current erection stability.

Verify anchors, bearings, orientation, restraint, and the required release stage.

Resolve field openings, anchor changes, and temporary attachments through approved details.

Treat the bolt, nut, washers, surfaces, and method as one compatible system.

A process mark is evidence only when tied to the actual completed verified stage.

Apply the WPS to the real material, fit-up, shielding, polarity, and temperature conditions.

Protect against arc radiation, fume accumulation, and unintended welding current paths.

Complete the specified examinations and resolve defects rather than accept appearance alone.

Preserve specified drains, vents, gaskets, sealant adhesion geometry, and movement paths.

Do not infer glazing support from level appearance or lifting attachment alone.

Check compatible materials, surface protection, and fastener behavior.

Use the stated stair, panel, clear-opening, and expansion assumptions without treating them as universal code rules.

Plan precast rotation, temporary bracing, storage, and bearing acceptance as separate stages.

Protect engineered timber and obtain authorized connection geometry before drilling.

Coordinate equipment axes with project control and supplier offsets.

Differentiate parallel offset from angular misalignment and remeasure after support adjustments.

Confirm the actual retained installation rather than rely only on old records.

Account for loads and restraint through each alteration or removal stage.

Interpret measurement changes with their load, datum, and temperature conditions.

Calculate thickness loss from original thickness without inferring an identical capacity reduction.

Use authorized repair and examination procedures for the actual defect and material.

Control pressure, raised components, contamination, and welding current paths.

Reverify connections changed after an earlier inspection.

Restore safeguards and record accepted changes before normal operation resumes.
