First, describe the work and worksite
A specialist erection crew will lift a delivered precast wall panel onto its released bearing and install the specified temporary support before crane release. This fictional learning example records planned controls; it supplies no actual inspections or work authorization.
- Panel identity, lifting design, inserts, bearing and bracing are established by the current erection documents.
- Crane, qualified rigging and signaling, exclusion and protected access require the actual lift arrangements.
- This excludes tilt-up casting, multi-crane lifts, slab erection and removal of temporary braces.
Questions before work
- Which panel-specific lifting and bracing documents apply?
- What confirms the receiving support and brace-anchor capacity?
- Who verifies stability before the crane releases the panel?
Build the analysis one step at a time
What will the worker do? How could someone be harmed? What prevents or reduces that exposure? Who checks the control, and when?
1. Release the panel and receiving support
Hazard: Wrong panel identification or incomplete bearing can cause collapse.
Control: Erection supervisor matches the panel with current documents and confirms bearing, anchors and temporary support are ready. Hold the lift for damage or unresolved design conditions.
Verification: Check panel marks and receiving-point release before rigging.
Why this belongs in the analysis: Support readiness must precede the lift.
2. Check inserts and rigging
Hazard: Incompatible hardware, damaged inserts or an unintended load path can drop the panel.
Control: Qualified rigging personnel use the panel-specific lifting arrangement and verify insert and hardware suitability against the design and applicable precast requirements. Never select gear from appearance alone.
Verification: Lift lead checks identification, configuration and required inspection evidence.
Why this belongs in the analysis: The panel’s weight alone does not establish every component’s suitability.
3. Establish the lift boundary
Hazard: A moving panel can strike or crush workers and people below.
Control: Clear the travel and receiving zones, identify essential erection positions and maintain agreed signals. Arrange access that keeps workers out of the panel’s swing and pinch path.
Verification: Lift lead confirms the boundary and communication before movement.
Why this belongs in the analysis: Receiving positions must be planned before the panel arrives.
4. Land and align the panel
Hazard: A suspended or partly supported panel can trap hands or overturn.
Control: Control movement with the planned method and use appropriate alignment tools from designated positions. Keep workers clear of bearing pinch points and do not release the crane prematurely.
Verification: Erection lead verifies bearing and alignment within the design limits.
Why this belongs in the analysis: Temporary landing is not proof of stability.
5. Install support before crane release
Hazard: An unsupported panel can collapse when rigging is removed.
Control: Install the specified braces and temporary connections on the released anchors. The designated erection authority confirms adequate support before authorizing crane release.
Verification: Record the required support checks against the panel erection plan before unrigging.
Why this belongs in the analysis: Crane release is a consequential hold point.
6. Protect and hand over the supported panel
Hazard: Unapproved brace changes, impact or loading can destabilize the panel.
Control: Protect brace locations from interference, identify connection work remaining and communicate restrictions. Leave brace removal to a separate documented permanent-support release.
Verification: Supervisor confirms support status and restrictions with the receiving crew.
Why this belongs in the analysis: The temporary system remains part of the worksite after the crane leaves.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Be careful around the equipment. | Clear the travel and receiving zones, identify essential erection positions and maintain agreed signals. Arrange access that keeps workers out of the panel’s swing and pinch path. |
| Check the area before starting. | Erection supervisor matches the panel with current documents and confirms bearing, anchors and temporary support are ready. Hold the lift for damage or unresolved design conditions. |
Decisions that change the analysis
May workers remove a brace once a connection looks complete?
Use the designated permanent-support release. The connection design, actual completion and inspection govern removal; this erection example does not supply that release.
What must be recorded before this example is used on a job?
Replace the scenario with the actual work, identify additional hazards with the crew, and record the applicable instructions, responsible people, inspection findings, unresolved actions and required authorization. A planned verification is not an inspection result.
Agree when the crew will pause
- Panel damage, insert uncertainty or receiving-support deviation appears.
- Wind, crane configuration or communication changes.
- A brace or anchor differs from the erection design.
After a pause, correct the condition, reassess the work, and obtain required authorization before restarting. Keep unresolved actions visible.

1. Describe your work and site
2. Work through each task
Describe an observable step, how someone could be harmed, and the control that acts on that hazard. Identify who checks it and what evidence is needed.
3. Record changes, checks, and open actions
Walk the work area, review with the crew, and resolve missing controls. Follow the required approval process. This tool does not judge completeness, verify signatures or authorize work.

Training needs to confirm
- Actual panel rigging, signaling and erection roles with applicable qualifications.
- Brace installation, release communication and fall-system instruction.
Confirm applicable qualifications, task instruction and actual training evidence for the people assigned. Related toolbox talks support crew discussion; they do not establish competence.
Common questions
Can this be used as a JSA?
Use the Task | Hazard | Control structure if it meets the employer’s format. Adapt the boundaries, controls, verification and records to the actual job.
Does this provide a completed USACE AHA?
No. Use the project’s required AHA process, risk method, supporting fields and acceptance requirements. The existing formwork AHA explains the additional structure.
Are these resources part of a paid course?
This walkthrough, browser draft builder and downloads are free public resources, separate from Academy course enrollment.
