25 cards. Read the term and the definition here. The deck at the top of this page is optional.

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.
