Step 1 of 4 · Working draft
Your job
Tell Jenkins what you’re planning and where the work will happen. Use the actual job details.
Use the published example’s suggestions when they fit your task, or write your own steps. These are planned controls, not verified worksite conditions.
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.
Walk through the plan with the people doing the work. Resolve missing controls and agree who checks them. Moving to the next step does not approve the work.
Confirm people, equipment and emergency arrangements
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.

Your Structural Steel Plumbing and Temporary Bracing JHA
Walk through the job in order. Use these possible hazards, planned controls and checks to start a conversation about your actual work.
011. Release the adjustment scheme
Possible hazards: An improvised pull can overload a member, anchor or unstable bay.
Planned controls: Erection lead confirms the designed plumbing arrangement, sequence and current frame state. Do not substitute attachment points or remove existing stability measures without the required design review.
Check before work: Lead compares equipment locations with the current erection documents.
022. Inspect and attach equipment
Possible hazards: A damaged cable, attachment or adjustment device can fail under tension.
Planned controls: Assigned personnel inspect rated plumbing gear and install attachments at specified locations from protected access. Keep people out of unsupported frame areas and tension paths.
Check before work: Lead verifies attachments and gear before loading the system.
033. Establish the tension boundary
Possible hazards: Cable recoil or a moving member can strike workers and survey personnel.
Planned controls: Define the full line-of-fire area for cables, anchors and frame movement. Position the survey team outside it; agree one adjustment leader and stop signals before tension is applied.
Check before work: Adjustment leader checks all affected positions and communication.
044. Adjust in the planned sequence
Possible hazards: Uneven pulls or overcorrection can destabilize the frame.
Planned controls: Apply adjustment only in the designed sequence and limits, with survey feedback between increments. Stop for unexpected movement, anchor distress or abnormal equipment response; never release a loaded line casually.
Check before work: Lead compares measured alignment and equipment response at each planned hold point.
055. Secure the accepted position
Possible hazards: Removing a tensioned device before permanent restraint is ready can let the bay move.
Planned controls: Complete the specified restraint and connection handover while maintaining required temporary support. Plumbing equipment removal requires competent-person approval and the project’s applicable release conditions.
Check before work: Lead records support status and removal approval before unloading gear.
066. Remove and hand over equipment
Possible hazards: Stored tension or unidentified unfinished work can expose the next crew.
Planned controls: Unload and remove equipment in the released sequence from protected positions. Inspect for damage and communicate remaining bracing, loading limits and unfinished connections.
Check before work: Foreperson confirms the bay restrictions with the receiving trade.
Example scope and starting conditions
An erection crew will plumb a partially erected building bay using designed plumbing cables and adjustment equipment from protected access. The bay remains under its temporary stability plan throughout adjustment. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- Attachment locations, force path, permitted adjustment sequence and removal conditions come from the erection design.
- Required plumbing equipment is installed before construction materials load the frame.
- Initial beam connecting, final bolting, foundation-anchor alteration and permanent connection acceptance are separate activities.
Know when to pause
- Anchor distress, cable damage or unexpected frame movement.
- Design, force limits or survey communication is unresolved.
- Temporary support must change or removal approval is absent.
After a pause, correct the condition, reassess the work, and obtain required authorization before restarting.
Free example and template
No account required. The worked example contains planned controls. The blank template is for your own work; neither includes fabricated inspection results, signatures or approval.

For managers
Does the team have what it needs to carry out the plan? Give the crew time, equipment and support, and make it clear who will resolve anything that is missing.
Manager checks and supporting resources
Confirm the people doing the work have the time, equipment, information and support to carry out the plan. Agree who checks the controls and who resolves open actions.
Questions to resolve before work
- Where are the designed cable attachments and anchor reactions carried?
- Who controls adjustment and access to tensioned-line paths?
- What approval is required before plumbing equipment is removed?
Training and qualifications to confirm
- Actual designed plumbing sequence and control of stored tension.
- Applicable steel-erection fall training, designated competent-person and survey/adjustment roles.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
May an aligned bay’s plumbing cables be removed immediately?
No. Alignment is a measurement, not the support-removal release. Confirm completed restraint and obtain the required competent-person approval before removing plumbing equipment.
What must the crew record for actual use?
Identify the actual equipment and work boundaries, responsible people, applicable criteria, inspection findings and open actions. Resolve changes with affected crews and obtain required project authorization before work.

Task-by-task control and verification rationale
1. Release the adjustment scheme
Hazard: An improvised pull can overload a member, anchor or unstable bay.
Control: Erection lead confirms the designed plumbing arrangement, sequence and current frame state. Do not substitute attachment points or remove existing stability measures without the required design review.
Verification: Lead compares equipment locations with the current erection documents.
Why this belongs in the analysis: Alignment forces must travel through a known structural path.
2. Inspect and attach equipment
Hazard: A damaged cable, attachment or adjustment device can fail under tension.
Control: Assigned personnel inspect rated plumbing gear and install attachments at specified locations from protected access. Keep people out of unsupported frame areas and tension paths.
Verification: Lead verifies attachments and gear before loading the system.
Why this belongs in the analysis: A convenient connection is not necessarily a designed plumbing attachment.
3. Establish the tension boundary
Hazard: Cable recoil or a moving member can strike workers and survey personnel.
Control: Define the full line-of-fire area for cables, anchors and frame movement. Position the survey team outside it; agree one adjustment leader and stop signals before tension is applied.
Verification: Adjustment leader checks all affected positions and communication.
Why this belongs in the analysis: The survey task must not place someone in the adjustment force path.
4. Adjust in the planned sequence
Hazard: Uneven pulls or overcorrection can destabilize the frame.
Control: Apply adjustment only in the designed sequence and limits, with survey feedback between increments. Stop for unexpected movement, anchor distress or abnormal equipment response; never release a loaded line casually.
Verification: Lead compares measured alignment and equipment response at each planned hold point.
Why this belongs in the analysis: Incremental observation catches changes before they become a larger release.
5. Secure the accepted position
Hazard: Removing a tensioned device before permanent restraint is ready can let the bay move.
Control: Complete the specified restraint and connection handover while maintaining required temporary support. Plumbing equipment removal requires competent-person approval and the project’s applicable release conditions.
Verification: Lead records support status and removal approval before unloading gear.
Why this belongs in the analysis: Aligned does not automatically mean self-supporting.
6. Remove and hand over equipment
Hazard: Stored tension or unidentified unfinished work can expose the next crew.
Control: Unload and remove equipment in the released sequence from protected positions. Inspect for damage and communicate remaining bracing, loading limits and unfinished connections.
Verification: Foreperson confirms the bay restrictions with the receiving trade.
Why this belongs in the analysis: The next crew must know which temporary measures remain necessary.
Compare control wording
| Needs improvement | More useful for this scenario |

Common questions
Can this example be used as a JSA?
Adapt its Task | Hazard | Control analysis to the employer’s format and actual conditions. The example is a teaching aid, not evidence that controls were checked.
What changes if the project requires an AHA?
Use the governing AHA format, risk method, supporting records and acceptance process. The published formwork AHA demonstrates that additional structure; changing a JHA title does not supply it.
Are these resources part of a paid course?
This walkthrough, browser draft builder and downloads are free public resources, separate from Academy course enrollment.
