Red Seal Ironworker (Generalist) cheat sheet

Confirm current approved revisions, piece marks, and specifications before work.

Use stated dimensions rather than scaling a distorted print.

Keep grid, edge, centreline, datum, and instrument references distinct.

Count intervals: the number of first-to-last spaces is one less than the number of points.

Keep length, area, volume, mass, and force units consistent.

Verify tool compatibility, calibration, isolation, hot-work controls, and fall-rescue arrangements.

Establish load mass, centre of gravity, lifting points, travel path, and landing support.

Use the rating for the actual sling, hitch, angle, and hardware arrangement.

For a symmetric static two-leg bridle, use W/(2 sin theta) when theta is above horizontal.

Do not assume four legs share equally or an off-centre load divides equally.

Match crane chart to actual configuration and apply its defined deductions.

Verify ground support; surface level alone does not establish bearing capacity.

Stop safely on lost required communication or an emergency stop signal.

Confirm stable support and required restraint before releasing rigging.

Match bar marks to schedule, material, shape, and location.

Measure clear cover to the nearest specified reinforcing surface.

Subtract bar diameter from equal-bar centre spacing to obtain clear gap.

For maximum spacing over a first-to-last span, round intervals up and add one bar.

Lap material overlaps and therefore adds to the total cut length for a required run.

Tie wire positions bars; it is not a structural splice or replacement anchorage.

Use approved coating repairs, compatible couplers, supports, and cage-stability arrangements.

Resolve congestion and openings before unauthorized cutting or relocation.

Maintain specified tendon profile, supports, anchorage, and corrosion protection.

Verify concrete readiness from the specified acceptance conditions, not surface appearance alone.

Use the matched calibrated jack and gauge relationship.

Pressure times effective piston area gives force in the stated simplified model.

Investigate unacceptable force or elongation disagreement rather than forcing a match.

Respect stored-energy controls and the approved stressing and tail-cutting sequence.

Use qualified grout proportions, venting, leak disposition, and filling checks.

Locate and assess embedded tendons before drilling or cutting existing members.

Verify anchors, bearing, orientation, plumbness, bracing, and erection-stage stability.

Do not remove temporary restraint solely because the permanent structure will eventually be stable.

Distinguish snug-tightening from the specified final pretensioning requirement.

Preserve qualified faying-surface and fastener assembly conditions.

Follow the WPS and required consumable, fit-up, qualification, and inspection controls.

Treat cracks and other unacceptable defects through an authorized repair process.

Preserve architectural fixed and sliding points, protective interfaces, and specified anchor procedures.

Correct soft foot and recheck equipment alignment after relevant support changes.

Verify actual existing conditions before relying on old drawings.

Assess retained and removed load paths throughout the dismantling sequence.

Confirm temporary supports are functional before interrupting permanent support.

Control stored energy and concealed fire or atmosphere hazards.

Do not equate local thickness-loss percentage with an automatically identical capacity loss.

Investigate recurring cracks or vibration rather than conceal the symptom.

Close inspections and dispositions, restore safeguards, and document authorized changes before return to service.
