Walkthrough script
Narration draft / not a recorded transcriptReadable lesson narration prepared for the original demonstration. Recorded captions and a time-aligned transcript will be published with the supplied footage.
- 01
Start with the current approved project plans and specifications. Confirm the revision and member detail, then agree on the work area, sequence, access, and inspection hold points with the responsible supervisor.
- 02
Check bundle identification, stage material for the assigned member, and handle it using the site lifting plan. Keep work paths clear and report material that is damaged or unclear.
- 03
Compare support type and locations with the approved member detail. Install the specified supports and check that they stay seated as bars are placed.
- 04
Place bars in sequence and secure required intersections using the specified tying method. Recheck completed ties and bar alignment as each section is built.
- 05
If steel conflicts with an embed or will not fit the approved arrangement, pause that area, keep it visible, and request an approved coordination direction before changing anything.
- 06
Before handoff, recheck supports and ties. Compare specified cover at the documented locations with the plans and specifications using the approved check method. Pause and obtain an approved direction for any conflict.
- 07
Protect the completed assembly from displacement and keep it visible until the required pre-pour review and release are complete. This narration is a draft for original footage and gives no universal dimensions or code requirements.
Field application
Practice the placement sequence
Work through staging, support, and coordination decisions using the current approved project documents and responsible instructor or supervisor. Revise an answer whenever you want.
Jobsite decision / 02
Supports shift as the assembly is tied
A support tips or slides while the crew ties the next section, and the reinforcement no longer rests as planned.
How should the crew restore the planned support arrangement?
Jobsite decision / 03
An embed blocks the planned bar path
The placed reinforcement meets an embed at a location where the approved arrangement does not show a route around it.
What is the safe next move for the affected area?
Instructor verification
Observe the placement before handoff
Use the current job documents and responsible instructor or supervisor for job-specific direction. These temporary marks are not saved and do not certify a learner.
The learner checks bundle identification against the placement sequence, keeps assigned material separate, and maintains a clear access route.
Not markedThe learner uses the support type and arrangement shown for the member and confirms supports bear as intended before adding bars.
Not markedRequired intersections are tied by the approved method, and the assembly remains aligned and stable as the next section is placed.
Not markedThe learner identifies the affected location, keeps it visible, and requests an approved direction without moving, cutting, bending, or welding bars on a guess.
Not markedThe learner checks supports and ties, protects reinforcement from displacement, and waits for the required review and release before concrete placement.

Learning targets
By the end of this lesson
- Plan the placement sequence with the current approved project detail, specifications, and responsible supervisor.
- Receive, identify, stage, and handle reinforcement without mixing work areas or damaging material.
- Install specified supports and secure the planned arrangement so it remains stable through planned access and placement preparation.
- Pause and escalate conflicts, then complete visible checks and hand off the work before concrete placement.
Field sequence
Work through the steps
- 01
Brief the placement sequence
Start with the current approved project plans, specifications, and approved field changes. Confirm the revision and member detail, then agree on the work area, assembly order, access routes, inspection hold points, and crew responsibilities with the instructor or supervisor. Resolve missing or conflicting direction before steel is issued to the work area.
- 02
Receive and stage the steel
Check bundle identification against the project sequence, then stage each bundle in its assigned area so the crew can select it without mixing members or blocking access. Use the approved lifting plan, keep clear of suspended loads, and report damaged or unclear material.
- 03
Set the specified supports
Compare the support type and locations with the current approved detail for this member. Prepare the work surface, install that support arrangement, and verify each support bears as intended before placing bars. Recheck the supports as the assembly grows; ask for an approved direction if the documented arrangement cannot be followed in the field.
- 04
Place and secure the planned arrangement
Place bars in the planned sequence and secure the required intersections using the tying method specified for the work. As each layer or connected section is built, check that completed ties are secure and the bars stay aligned with the current detail. Do not substitute supports or change the arrangement based on convenience.
- 05
Coordinate conflicts without changing the steel
Check the planned path around openings, embeds, joints, and other trades as work proceeds. If the arrangement does not fit or another activity would displace it, pause the affected area, keep the condition visible, and request an approved direction from the responsible instructor or supervisor.
- 06
Check and hand off before the pour
Walk the completed area against the current approved plans and specifications. Recheck the specified supports and completed ties, then compare specified cover at the documented reference locations with the project requirements using the approved check method. If the documents or field conditions conflict, pause the affected work and obtain an approved direction. Clear loose tie ends and obstructions as directed, protect the assembly from traffic, and keep reinforcement visible until the required pre-pour review and release are complete.
Plans and local requirements
Plans and applicable code
Use the current approved project plans and specifications, approved changes, and the applicable adopted code for this work. Project documents govern the member-specific arrangement and measurement requirements; this lesson supplies no universal spacing, cover, lap, or support values. If the documents conflict or the planned steel will not fit, pause the affected work and ask the responsible instructor or supervisor to obtain an approved direction before proceeding.
Before the work
Tools and materials
- Current approved reinforcement detail, specifications, and approved field changes for the work area
- Project-identified reinforcement bundles and specified chairs, spacers, or other supports
- Approved lifting and staging equipment, tie tools, and measuring tools required by the work plan
- Task-appropriate gloves, eye protection, protruding-steel protection, and the site safety plan
Observable checks
Before you move on
- Bundles are identified for the correct work area and staged without obstructing access or mixing member material.
- Support type and locations match the current approved member detail, and supports remain seated as the assembly is built.
- Required intersections are tied by the specified method and completed ties are rechecked as each section is added.
- Specified cover is compared with the plans and specifications at their documented locations using the approved check method.
- The assembly stays stable during planned access, and conflicts are documented and resolved through the approval path.
- Required pre-pour review is complete while the reinforcement remains visible and protected.
Watch for these
Common mistakes
- Issuing a bundle to the work area before confirming its identification and placement sequence.
- Using convenient blocks or leftover material instead of the supports specified for the member.
- Leaving ties loose or allowing staged bundles, foot traffic, or tools to displace completed work.
- Shifting, cutting, bending, or welding bars to clear another item without approved direction.
- Covering the assembly or allowing concrete placement before the required review and release.
Work safely
Safety notes
- Follow the site lifting plan, stay clear of suspended bundles, and keep hands out of pinch points while setting bars.
- Use gloves and eye protection when tying steel; turn or control sharp tie ends as the approved work method requires.
- Protect exposed bar ends using the site-approved system and maintain clear travel and access paths.
- Stop work and alert the responsible supervisor if material, supports, access, or the planned arrangement creates an unsafe condition.
