Red Seal Ironworker (Reinforcing) key terms

An identifier linking a specific reinforcing item to its scheduled material, shape, dimensions, quantity, and intended location in the work.

A controlled reference from which dimensions or elevations are established, allowing layout and inspection measurements to relate consistently to the design.

A process for identifying currently authorized information and managing the effects of changes on drawings, schedules, fabricated material, and installed work.

A traceable project question that identifies a specific missing or conflicting requirement so an authorized clarification can be issued and coordinated.

The required length along a fabricated bar as defined by the applicable schedule and bending convention, including specified allowances rather than assumed geometry.

The material consumed by a cutting operation, which must be allowed for when deriving finished pieces and remaining offcuts from stock.

Partial elastic recovery after the forming force is removed, which can make the released bend angle differ from the loaded setup position.

A forming component around which a bar is bent, selected to produce the required geometry for the specified material and process.

A detailed overlap arrangement that transfers force between reinforcing bars through their interaction with surrounding concrete over the specified splice region.

A specified connector system that transfers force between reinforcing bars when compatible components, preparation, engagement, and installation requirements are satisfied.

A support used to hold reinforcement at its required position, selected for the construction loads, substrate, geometry, and compatibility requirements.

The specified concrete distance from a concrete surface to the nearest outside surface of the relevant outermost reinforcement or metal component.

The permitted load for identified lifting equipment under its stated configuration and conditions, not a universal value independent of hitch and angle.

The point representing the resultant location of a load's weight, used when assessing balance and the reactions at proposed lifting points.

The defined angle of a sling leg relative to a stated reference, used with the appropriate rating information and lift geometry.

Stable support material placed under stored or landed loads to provide bearing, clearance, and controlled handling access when appropriately selected and arranged.

The prestressing element and associated arrangement identified for a particular structural load path, installed and stressed according to its specified system.

The measured increase in tendon length during a stressing operation, compared with the specified expectation and recorded with the appropriate force information.

The local region where concentrated prestressing force enters the concrete through the specified anchorage and associated reinforcement and bearing arrangement.

The controlled filling of a specified tendon duct with suitable grout to establish the intended protection and bond after the required preceding operations.

A defined stage at which work must receive the specified verification and release before proceeding to an operation that would conceal or restrict correction.

The maintained link between a physical item and its verified material identity and records through delivery, cutting, rebundling, and installation.

An observed departure from an applicable requirement, recorded factually and resolved through the authorized assessment, correction, or disposition process.

An established relationship between an instrument's indication and a reference quantity, used with applicable verification to support reliable measurement and acceptance decisions.
