Red Seal Ironworker (Structural/Ornamental) key terms
Red Seal Ironworker (Structural/Ornamental) · Get comfortable with the vocabulary.
- Drawing reference
The identified view, detail, revision, and coordinate basis needed to interpret a dimension as part of the correct approved assembly.
- Section view
A representation through an assembly that reveals internal or vertical relationships not adequately described by a plan or external outline.
- Benchmark
A verified elevation reference used to establish instrument height and transfer levels within the project's controlled survey system.
- Construction tolerance
The specified permissible variation for a defined measurement, applied to its stated reference rather than assumed to cover every other requirement.
- Handed assembly
A component whose offsets or connection geometry are specific to one orientation or side, even if a mirrored counterpart has equal length.
- Load moment
The turning effect represented in a stated static model by force multiplied by its perpendicular distance from a reference point.
- Vertical component factor
The fraction of a sling's tension acting vertically in a defined geometry, used without confusing the angle's horizontal or vertical reference.
- Gross suspended load
The total supported load under the particular chart definition, including the accessories and components that the stated capacity basis requires.
- Reeving
The arrangement of rope through sheaves and supporting parts, affecting ideal mechanical advantage, line travel, and the actual system's operating requirements.
- Below-hook device
An engineered lifting component between the crane hook and load, with its own permitted orientation, force path, attachments, and rating.
- Erection-stage stability
The ability of the actual partially completed structural arrangement to resist the relevant construction-stage actions before all permanent restraints are installed.
- Bolt grip arrangement
The defined connected stack and associated hardware geometry used with the fastener specification, distinct from assuming a bolt length from one plate alone.
- Pre-installation verification
A specified check that the intended bolting assembly and method achieve the required condition before that setup is relied on in production.
- Faying-surface condition
The qualified interface preparation between connected parts, important where connection behavior depends on the specified friction and clamping arrangement.
- Nondestructive examination
An inspection method applied under the required qualifications and acceptance criteria to obtain information without intentionally destroying the component being examined.
- Movement allowance
The designed space or connection travel that permits specified changes in dimension or position without defeating the assembly's support and restraint functions.
- Bond breaker
A specified feature preventing unintended adhesion at a sealant-joint surface so the material can deform according to the approved joint design.
- Setting block
A compatible support element placed as specified beneath glazing to distribute loads and establish the intended contact and positioning conditions.
- Parallel offset misalignment
A condition in which two intended coaxial shaft axes have the same direction but are displaced from one another sideways.
- Angular misalignment
A difference in direction between intended aligned axes or faces that requires interpretation and correction using the specified equipment measurement method.
- Condition survey
A documented assessment of actual geometry, material, deterioration, prior alteration, and other relevant facts before repair or removal decisions are made.
- Intermediate load path
The force-transfer arrangement that exists at a particular step of alteration or dismantling, which can differ from both original and final structures.
- Repair disposition
The authorized decision and method addressing a specific defect or changed condition, including relevant material, process, and acceptance requirements.
- Remaining thickness
The measured local metal dimension after loss or alteration, interpreted with suitable instrument conditions and distinguished from a complete capacity assessment.
- Technical closeout
Confirmation and documentation of accepted installed work, resolved dispositions, required examinations, restored safeguards, and authorized readiness for subsequent service.
