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 Supported Masonry Wall Section Rebuilding JHA
Walk through the job in order. Use these possible hazards, planned controls and checks to start a conversation about your actual work.
011. Confirm the supported repair release
Possible hazards: A hidden load or an unsupported retained edge can produce collapse when damaged units are removed.
Planned controls: Restoration lead checks the structural survey, engineered repair/removal plan, installed support release and utility/material clearance. Confirm the unoccupied boundary and loading isolation; no removal starts from an assumption that a small section carries little load.
Check before work: Lead verifies the records apply to this section and current structure.
022. Protect supports and the work bay
Possible hazards: Debris, carts or poor access can strike shores or expose workers beside unstable masonry.
Planned controls: Establish the plan’s work and debris boundaries, protected access and manageable waste route. Keep shore bases and braces clear, isolate affected areas on both sides and implement the selected tool and silica controls without disturbing support.
Check before work: Lead checks support protection, access and the controlled debris path before tools start.
033. Remove the designated section
Possible hazards: Uncontrolled prying or cutting can detach retained masonry or release a falling piece.
Planned controls: Follow the released removal order in controlled, supported pieces using specified tools and exposure controls. Keep people outside drop paths, protect retained edges and stop for unexpected movement, binding or concealed connections; do not widen the removal to obtain easier access.
Check before work: Removal lead compares progress and retained conditions with the planned hold points.
044. Prepare the released rebuilding interface
Possible hazards: Damaged bearings, unsuitable remaining units or missing ties can prevent the repair from connecting correctly.
Planned controls: Have the retained support and interface checked under the repair plan before rebuilding. Identify the specified replacement units, mortar and connections; resolve damaged edges or changed geometry through technical disposition rather than filling the discrepancy with extra mortar.
Check before work: Restoration lead records actual interface findings and the rebuilding release.
055. Rebuild bond and connections
Possible hazards: Poor bond, omitted reinforcement or wet mortar contact can leave a weak repair and injure workers.
Planned controls: Install the repair’s specified units, bond, ties or reinforcement from stable access while maintaining support and load isolation. Control handling and cement contact, verify concealed connections before closure and protect the work under actual product and design curing requirements.
Check before work: Lead records unit, bond and concealed connection findings at the required hold points.
066. Hand over without releasing support
Possible hazards: Early reloading or shore removal can destabilize masonry before its required acceptance.
Planned controls: Collect contained waste, protect the rebuilding and transfer actual records, cure restrictions and open actions. Leave supports and loading isolation in place until the designated structural acceptance and separately planned support-removal/reloading release.
Check before work: Receiving lead confirms restrictions and the authority controlling the later release.
Example scope and starting conditions
A restoration crew will remove and rebuild one damaged ground-level section of load-bearing brick masonry in an unoccupied building bay after the structural survey, engineered shoring, load isolation and removal plan are released. The reconstructed section remains protected for separate cure and structural acceptance. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- Current repair documents define the removal boundary, retained-edge support, replacement units, bond, connections and cure/loading restrictions.
- Temporary supports are independently installed and released; utilities and suspect materials are resolved before disturbance.
- Shoring design, hazardous-material abatement, unsupported demolition, helical crack stitching, cavity-tie repair and shore removal are excluded.
Know when to pause
- Additional damage, a concealed service or a condition outside the survey is found.
- A shore, retained edge or masonry section moves unexpectedly.
- Replacement bond, cure protection or structural acceptance is unresolved.
After a pause, correct the condition, reassess the work, and obtain required authorization before restarting.

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
- Which survey and support records release this precise removal boundary?
- How will retained masonry and each removed piece remain controlled during the sequence?
- Who accepts rebuilt bond/connections and authorizes later reloading or support removal?
Training and qualifications to confirm
- The section-specific supported removal/rebuilding sequence, retained-edge monitoring and authority to stop for changed conditions.
- Applicable tool, silica, hazardous-material awareness, utility-clearance and wet-mortar handling instruction.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
Can the shores be removed when the rebuilt wall looks complete?
No. Keep the repair’s support and load restrictions until the required cure and structural acceptance are documented, then follow the separately released removal/reloading sequence. This example authorizes no occupancy or support removal.
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. Confirm the supported repair release
Hazard: A hidden load or an unsupported retained edge can produce collapse when damaged units are removed.
Control: Restoration lead checks the structural survey, engineered repair/removal plan, installed support release and utility/material clearance. Confirm the unoccupied boundary and loading isolation; no removal starts from an assumption that a small section carries little load.
Verification: Lead verifies the records apply to this section and current structure.
Why this belongs in the analysis: The example begins after support engineering and installation, not instead of them.
2. Protect supports and the work bay
Hazard: Debris, carts or poor access can strike shores or expose workers beside unstable masonry.
Control: Establish the plan’s work and debris boundaries, protected access and manageable waste route. Keep shore bases and braces clear, isolate affected areas on both sides and implement the selected tool and silica controls without disturbing support.
Verification: Lead checks support protection, access and the controlled debris path before tools start.
Why this belongs in the analysis: Ordinary cleanup and material routes must not interfere with the temporary load path.
3. Remove the designated section
Hazard: Uncontrolled prying or cutting can detach retained masonry or release a falling piece.
Control: Follow the released removal order in controlled, supported pieces using specified tools and exposure controls. Keep people outside drop paths, protect retained edges and stop for unexpected movement, binding or concealed connections; do not widen the removal to obtain easier access.
Verification: Removal lead compares progress and retained conditions with the planned hold points.
Why this belongs in the analysis: Small changes to the boundary can change the supported repair’s load path.
4. Prepare the released rebuilding interface
Hazard: Damaged bearings, unsuitable remaining units or missing ties can prevent the repair from connecting correctly.
Control: Have the retained support and interface checked under the repair plan before rebuilding. Identify the specified replacement units, mortar and connections; resolve damaged edges or changed geometry through technical disposition rather than filling the discrepancy with extra mortar.
Verification: Restoration lead records actual interface findings and the rebuilding release.
Why this belongs in the analysis: Replacing visible bricks alone does not restore the designed connection.
5. Rebuild bond and connections
Hazard: Poor bond, omitted reinforcement or wet mortar contact can leave a weak repair and injure workers.
Control: Install the repair’s specified units, bond, ties or reinforcement from stable access while maintaining support and load isolation. Control handling and cement contact, verify concealed connections before closure and protect the work under actual product and design curing requirements.
Verification: Lead records unit, bond and concealed connection findings at the required hold points.
Why this belongs in the analysis: The new section must connect to retained work under the repair detail.
6. Hand over without releasing support
Hazard: Early reloading or shore removal can destabilize masonry before its required acceptance.
Control: Collect contained waste, protect the rebuilding and transfer actual records, cure restrictions and open actions. Leave supports and loading isolation in place until the designated structural acceptance and separately planned support-removal/reloading release.
Verification: Receiving lead confirms restrictions and the authority controlling the later release.
Why this belongs in the analysis: A completed face supplies neither strength evidence nor permission to remove shores.

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.
