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 Bolted Steel Beam Strengthening Plates 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 retrofit stage
Possible hazards: Disturbing an existing connection without the designed load-transfer condition can destabilize the beam or surrounding structure.
Planned controls: Retrofit lead identifies the beam and obtains current design, accepted condition and actual temporary-support release evidence. Confirm stage-specific loading limits and hold points. Resolve changes or missing records with the responsible engineer before existing-connection disturbance or fit-up.
Check before work: Lead matches the beam and intended stage to the actual support, load and connection-release documents.
022. Prepare plate handling and protected access
Possible hazards: An inadequately restrained plate, improvised lifting point or exposed work position can cause crush injuries or a fall.
Planned controls: Use released protected access and the plate-handling method for actual weight, geometry and space. Confirm designated attachment and restraint before movement. Close drop and movement areas around and below the connection; coordinate neighboring work to preserve supports and handling arrangements.
Check before work: Handling lead verifies the accepted access, plate identity, restraint and clear receiving positions.
033. Verify components and fit the first plate
Possible hazards: Wrong components, unaccepted holes or forced alignment can introduce a defective connection or unexpectedly load the existing beam.
Planned controls: Check plate identity, accepted holes, bolt assemblies and mating surfaces against the design. Restrain the plate under the released method during alignment. Keep hands clear; refer mismatch rather than drifting, enlarging holes or removing existing fasteners outside the engineered sequence.
Check before work: Connection lead checks fit-up findings at the prescribed stage before allowing further connection work.
044. Complete the staged plate connections
Possible hazards: An out-of-sequence fastener change or unsupported plate can alter the temporary load path and trap nearby workers.
Planned controls: Trained crew follows the actual staged installation sequence while retaining the required supports and plate restraints. Disturb an existing fastener only at its engineer-defined release point. Install specified assemblies using the accepted joint procedure and required verification; keep hands clear of powered-tool reaction and movement points.
Check before work: Connection lead confirms each specified hold point and records the required assembly and installation findings.
055. Obtain connection and load-transfer disposition
Possible hazards: Missing bolts, unresolved fit-up or an assumed inspection result can transfer load through an incomplete strengthening assembly.
Planned controls: Assigned reviewer completes required plate/connection checks and records findings. Refer discrepancies or changed beam/support behavior to the responsible engineer. Retain loading and support restrictions until required connection acceptance and engineered load-transfer direction are obtained.
Check before work: Retrofit lead checks recorded findings and the applicable engineering disposition before requesting support release.
066. Complete the released handover
Possible hazards: Premature support removal or uncommunicated loading limits can undo the stable retrofit condition after the crew leaves.
Planned controls: Only the assigned crew follows the actual engineer-released support-transfer or removal method. Preserve any supports not released for this stage and protect the work area during the transition. Record actual resulting conditions and remaining defects; hand over the beam’s accepted service or construction-load restrictions to the receiving lead.
Check before work: Retrofit lead records the release basis, actual transition findings and the receiving person’s remaining restrictions.
Example scope and starting conditions
A qualified crew will fit predrilled, engineer-specified strengthening plates to an existing building beam under its released temporary-support and load-transfer condition. Required holes are independently accepted. Work covers plate handling, fit-up, staged connection completion and engineered load-transfer handover; drilling, welding and uncontrolled loaded-connection changes are excluded. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- Current retrofit design identifies the beam, accepted existing condition, temporary support, loading limits and connection sequence. Applicable engineering hold points govern existing-fastener disturbance and support release.
- Predrilled plates, holes and bolt assemblies are independently accepted. Current connection requirements establish joint type, surface preparation, installation and inspection evidence; no universal torque or pretension rule applies.
- This is partial coverage of structural retrofit 238120-29. New-frame bolting, drilling, hot work, beam removal and unreviewed changes to material, holes, supports or the existing load path require separate analyses.
Know when to pause
- The actual beam, support condition, load restrictions or required engineering release differs from the current retrofit design.
- Plate fit, holes, bolt assemblies or mating surfaces do not match the accepted details, or beam/support movement is unexpected.
- An existing fastener must be disturbed outside the sequence, required inspection evidence is unavailable, or access and plate restraint 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
- Which engineered support and load-transfer condition releases this existing beam for the exact plate connection sequence?
- What actual plate, hole and bolt records establish accepted fit-up and the specified installation and inspection method?
- Who controls existing-fastener disturbance and the final support-release hold point, including any unexpected beam movement?
Training and qualifications to confirm
- Retrofit briefing on the engineered load path, support restrictions, plate sequence and hold points; recognize movement or mismatch requiring engineering direction.
- Plate-handling and joint-installation instruction on hands-clear positioning, specified assembly verification and recorded findings without assumed torque values.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
Does this repeat magnetic drilling or ordinary structural bolting?
No. Magnetic drilling ends before connection installation; new-frame bolting excludes loaded-existing-connection changes. This operation installs a designed strengthening assembly while preserving and then transferring a specific load path. Accepted holes and engineering direction are prerequisites supplied by the actual project.
What must the crew record for actual use?
Record the existing beam and design revisions, accepted condition and holes, plate and bolt identities, temporary support and loading basis, staged fastener permissions, joint installation and verification method, assigned hold-point roles and actual fit-up and inspection findings. Retain engineering dispositions, actual support-transfer results and remaining load limits; do not invent torque settings or sign an engineering release from this draft.

Task-by-task control and verification rationale
1. Release the identified retrofit stage
Hazard: Disturbing an existing connection without the designed load-transfer condition can destabilize the beam or surrounding structure.
Control: Retrofit lead identifies the beam and obtains current design, accepted condition and actual temporary-support release evidence. Confirm stage-specific loading limits and hold points. Resolve changes or missing records with the responsible engineer before existing-connection disturbance or fit-up.
Verification: Lead matches the beam and intended stage to the actual support, load and connection-release documents.
Why this belongs in the analysis: A visible support does not establish that it carries the load required by the retrofit design.
2. Prepare plate handling and protected access
Hazard: An inadequately restrained plate, improvised lifting point or exposed work position can cause crush injuries or a fall.
Control: Use released protected access and the plate-handling method for actual weight, geometry and space. Confirm designated attachment and restraint before movement. Close drop and movement areas around and below the connection; coordinate neighboring work to preserve supports and handling arrangements.
Verification: Handling lead verifies the accepted access, plate identity, restraint and clear receiving positions.
Why this belongs in the analysis: Small plate dimensions do not remove the need to control its weight and changing support.
3. Verify components and fit the first plate
Hazard: Wrong components, unaccepted holes or forced alignment can introduce a defective connection or unexpectedly load the existing beam.
Control: Check plate identity, accepted holes, bolt assemblies and mating surfaces against the design. Restrain the plate under the released method during alignment. Keep hands clear; refer mismatch rather than drifting, enlarging holes or removing existing fasteners outside the engineered sequence.
Verification: Connection lead checks fit-up findings at the prescribed stage before allowing further connection work.
Why this belongs in the analysis: A connection that fits only through unapproved force has not demonstrated conformity with the design.
4. Complete the staged plate connections
Hazard: An out-of-sequence fastener change or unsupported plate can alter the temporary load path and trap nearby workers.
Control: Trained crew follows the actual staged installation sequence while retaining the required supports and plate restraints. Disturb an existing fastener only at its engineer-defined release point. Install specified assemblies using the accepted joint procedure and required verification; keep hands clear of powered-tool reaction and movement points.
Verification: Connection lead confirms each specified hold point and records the required assembly and installation findings.
Why this belongs in the analysis: Tightening new bolts is only one part of maintaining the designed retrofit load path.
5. Obtain connection and load-transfer disposition
Hazard: Missing bolts, unresolved fit-up or an assumed inspection result can transfer load through an incomplete strengthening assembly.
Control: Assigned reviewer completes required plate/connection checks and records findings. Refer discrepancies or changed beam/support behavior to the responsible engineer. Retain loading and support restrictions until required connection acceptance and engineered load-transfer direction are obtained.
Verification: Retrofit lead checks recorded findings and the applicable engineering disposition before requesting support release.
Why this belongs in the analysis: Completing the visible bolt pattern does not establish acceptance of the strengthened member or temporary load transfer.
6. Complete the released handover
Hazard: Premature support removal or uncommunicated loading limits can undo the stable retrofit condition after the crew leaves.
Control: Only the assigned crew follows the actual engineer-released support-transfer or removal method. Preserve any supports not released for this stage and protect the work area during the transition. Record actual resulting conditions and remaining defects; hand over the beam’s accepted service or construction-load restrictions to the receiving lead.
Verification: Retrofit lead records the release basis, actual transition findings and the receiving person’s remaining restrictions.
Why this belongs in the analysis: Connection acceptance, temporary-support release and return to service are accountable decisions rather than one assumed finish.
Compare control wording
| Needs improvement | More useful for this scenario |
|---|---|
| Use the new-frame bolting sequence on this beam. | Match the existing load path and temporary support to the retrofit engineer’s staged plate connection and hold points. |
| All bolts are tight; remove the supports. | Obtain actual connection findings and the engineer’s applicable load-transfer release before assigned personnel follow the support-removal method. |
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.
