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 Controlled Foundation Wall Concrete Placement 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 identified wall for placement
Possible hazards: An unreleased form or changed concrete mix can impose pressure beyond the designed ties and supports.
Planned controls: Placement lead checks the actual wall, current form drawings, documented pre-placement findings and the mix-based placement method. Resolve missing reviews or changes to wall geometry, form components, concrete behavior or consolidation with the responsible planner before authorizing delivery into the forms.
Check before work: Lead matches the wall identity and concrete information to the actual placement-release records.
022. Establish protected work and observation positions
Possible hazards: Workers on improvised access or in a form failure area can fall or be struck during a sudden release.
Planned controls: Crew uses the released platform and access arrangement with required fall protection, safe hose positions and protected observation points. Close affected areas beside and below the pour. Brief the stop signal, responsible communicator and safe withdrawal route; keep unrelated workers outside the boundary.
Check before work: Placement lead walks the access and boundaries with the hose crew and assigned observers.
033. Admit concrete through the ready pumping system
Possible hazards: Unexpected hose movement or unsuitable arriving concrete can expose the crew and disrupt the planned wall progression.
Planned controls: Pump crew confirms its separately completed setup and readiness before flow. Placement lead checks the delivered concrete against the accepted wall plan and agrees the start command with the pump operator. Follow the actual hose-handling and startup procedure; hold changed or questionable deliveries for disposition.
Check before work: Assigned communicator verifies operator contact and the lead confirms acceptance of the delivery before placement.
044. Place and consolidate within the wall plan
Possible hazards: Uncontrolled rise, concentrated placement or excessive vibration can increase pressure and cause form movement or blowout.
Planned controls: Crew follows the specified progression, placement-rate limit and consolidation method. The designated lead tracks actual progress and directs flow accordingly; observers watch the identified form and tie areas from protected locations. Stop pumping for unexpected movement, distortion or changing leakage, and withdraw to the planned safe positions.
Check before work: Lead checks actual progression against the plan and receives the observers’ reports during placement.
055. Manage interruptions and complete the wall
Possible hazards: An assumed restart or an improvised finish can overload forms or leave an unaccepted construction joint.
Planned controls: For interruptions, preserve the boundary and obtain the responsible placement planner’s direction on restart or joint treatment when required. Complete the specified wall top and embedded-item checks from protected access. Do not reach across an uncontrolled hose or alter ties and supports to solve a finishing problem.
Check before work: Lead records interruption decisions, completed limits and unresolved defects for the wall.
066. Protect the wall and hand over restrictions
Possible hazards: Early disturbance, neglected curing or premature stripping can damage the wall or remove necessary support.
Planned controls: Begin the specified curing and protection method and leave the form support arrangement undisturbed. Record actual placement observations and any concerns for the responsible reviewer. Communicate access, load and form-removal restrictions to the next lead; clean equipment under its separate safe shutdown and washout method.
Check before work: Placement lead confirms the curing owner and receiving lead understand the recorded restrictions and open actions.
Example scope and starting conditions
A concrete crew will pump-place one vertical building foundation wall in erected gang forms from protected platform positions. The actual design and placement plan govern fresh-concrete pressure, progression and consolidation. Work begins at the pre-placement release and ends with curing handover and retained form-removal restrictions. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- Forms, ties, supports, platform access and reinforcement receive their actual required pre-placement review. The current form design and concrete information establish the permitted placement rate, progression and consolidation method without a universal pour-rate rule.
- Pump setup, line condition and hose operating limits are independently ready before placement. The crew assigns one effective pump-stop communication route and observers who can monitor forms from protected positions outside potential failure areas.
- This is partial coverage of foundation activity 238110-07 and placement activity 238110-09, limited to a vertical building wall. Excavation access, new form erection, slab pours, concrete buckets, stripping and reshoring are excluded.
Know when to pause
- The delivered mix, wall configuration or form arrangement no longer matches the released pressure and placement basis.
- Forms move or distort, leakage changes unexpectedly, a support is disturbed, or observers lose a protected view.
- Access, hose control, pump communication or conditions needed for the specified progression cannot be maintained.
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
- What actual form design and mix conditions establish this wall’s permissible placement progression and fresh-concrete pressure?
- Who observes the forms safely and can communicate an immediate pump stop if movement or leakage changes?
- Which positions protect hose and consolidation workers, and how will the curing and form-removal restrictions be handed over?
Training and qualifications to confirm
- Wall-placement instruction on design-specific pressure/progression limits, distress warning signs, protected observation and immediate pump-stop communication.
- Hose and consolidation equipment instruction, protected access and wet-cement protection; recognize when a mix change or interruption requires planner direction.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
Is this another slab-pouring example?
No. The slab example distributes concrete across a prepared horizontal area. A vertical wall requires active control of fresh-concrete pressure and its effect on form ties and supports. The current form and placement design determines the permissible rate and progression; this example provides no standard numeric rate.
What must the crew record for actual use?
Record the wall identification, form drawing and placement-plan revisions, actual pre-placement findings, concrete delivery information, pressure and progression basis, assigned observer and stop-communication roles, actual progression and interruptions, concerns and dispositions. Record the curing handover and remaining load or form-removal restrictions; do not mark a strength release from this teaching example.

Task-by-task control and verification rationale
1. Release the identified wall for placement
Hazard: An unreleased form or changed concrete mix can impose pressure beyond the designed ties and supports.
Control: Placement lead checks the actual wall, current form drawings, documented pre-placement findings and the mix-based placement method. Resolve missing reviews or changes to wall geometry, form components, concrete behavior or consolidation with the responsible planner before authorizing delivery into the forms.
Verification: Lead matches the wall identity and concrete information to the actual placement-release records.
Why this belongs in the analysis: Vertical fresh concrete creates a pressure problem that slab placement checks do not resolve.
2. Establish protected work and observation positions
Hazard: Workers on improvised access or in a form failure area can fall or be struck during a sudden release.
Control: Crew uses the released platform and access arrangement with required fall protection, safe hose positions and protected observation points. Close affected areas beside and below the pour. Brief the stop signal, responsible communicator and safe withdrawal route; keep unrelated workers outside the boundary.
Verification: Placement lead walks the access and boundaries with the hose crew and assigned observers.
Why this belongs in the analysis: Observation helps only when workers can see the forms without standing where failure would reach them.
3. Admit concrete through the ready pumping system
Hazard: Unexpected hose movement or unsuitable arriving concrete can expose the crew and disrupt the planned wall progression.
Control: Pump crew confirms its separately completed setup and readiness before flow. Placement lead checks the delivered concrete against the accepted wall plan and agrees the start command with the pump operator. Follow the actual hose-handling and startup procedure; hold changed or questionable deliveries for disposition.
Verification: Assigned communicator verifies operator contact and the lead confirms acceptance of the delivery before placement.
Why this belongs in the analysis: A ready form and a ready pump must meet at one controlled start decision.
4. Place and consolidate within the wall plan
Hazard: Uncontrolled rise, concentrated placement or excessive vibration can increase pressure and cause form movement or blowout.
Control: Crew follows the specified progression, placement-rate limit and consolidation method. The designated lead tracks actual progress and directs flow accordingly; observers watch the identified form and tie areas from protected locations. Stop pumping for unexpected movement, distortion or changing leakage, and withdraw to the planned safe positions.
Verification: Lead checks actual progression against the plan and receives the observers’ reports during placement.
Why this belongs in the analysis: The planned rate must remain effective as delivery and concrete conditions change.
5. Manage interruptions and complete the wall
Hazard: An assumed restart or an improvised finish can overload forms or leave an unaccepted construction joint.
Control: For interruptions, preserve the boundary and obtain the responsible placement planner’s direction on restart or joint treatment when required. Complete the specified wall top and embedded-item checks from protected access. Do not reach across an uncontrolled hose or alter ties and supports to solve a finishing problem.
Verification: Lead records interruption decisions, completed limits and unresolved defects for the wall.
Why this belongs in the analysis: A pump restart restores flow; it does not resolve the structural consequences of an interrupted placement.
6. Protect the wall and hand over restrictions
Hazard: Early disturbance, neglected curing or premature stripping can damage the wall or remove necessary support.
Control: Begin the specified curing and protection method and leave the form support arrangement undisturbed. Record actual placement observations and any concerns for the responsible reviewer. Communicate access, load and form-removal restrictions to the next lead; clean equipment under its separate safe shutdown and washout method.
Verification: Placement lead confirms the curing owner and receiving lead understand the recorded restrictions and open actions.
Why this belongs in the analysis: Placement completion is separate from concrete-strength acceptance and authorization to remove forms.
Compare control wording
| Needs improvement | More useful for this scenario |
|---|---|
| Keep pumping while the crew watches for a problem. | Placement lead controls the design-specific progression; protected observers report changes through an agreed immediate stop route. |
| Use yesterday’s wall pour rate. | Match this wall’s form design, concrete information and consolidation method to the actual permitted progression before flow begins. |
Common questions
Can this example be used as a JSA?
Adapt its Task | Hazard | Control analysis to the employer’s JSA format and actual work. Confirm assigned checks and record real findings before relying on the plan.
What changes if the project requires an AHA?
Use the project’s governing AHA format, risk method, supporting records and acceptance process. The published formwork AHA illustrates that additional structure; this JHA establishes no AHA risk rating or acceptance.
