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 Initial Beam Connecting 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 erection bay
Possible hazards: An unstable column or wrong erection sequence can lead to frame collapse.
Planned controls: Erection lead confirms column support, bearing points and the current beam sequence. Compare member marks and connection details with drawings; hold the lift for unresolved support or design changes.
Check before work: Lead records the bay release before rigging the beam.
022. Prepare connector access
Possible hazards: Falls, dropped tools or inadequate rescue access can expose connectors and crews below.
Planned controls: Provide the specified protected work positions and task-specific fall arrangements under Subpart R. Secure tools, separate work below and confirm a practicable rescue plan before connectors enter.
Check before work: Lead checks access and connector briefing before the lift starts.
033. Hoist and guide the member
Possible hazards: A rotating beam can strike or trap a connector.
Planned controls: Use the lift plan and agreed signals; keep connectors outside the approaching member’s swing and pinch paths until controlled positioning is established. Use alignment tools without placing fingers in connection holes.
Check before work: Signal person and connectors confirm stop communication at approach.
044. Make initial connections
Possible hazards: Insufficient initial bolts can let the beam fall at crane release.
Planned controls: Install the specified initial connection. For this solid-web beam, secure each connection with at least two drawing-size and strength bolts drawn wrench-tight, or the engineer-specified equivalent; follow any additional stability requirements.
Check before work: Erection lead checks both ends against the drawings and applicable release criteria.
055. Release crane support
Possible hazards: Premature unrigging can expose an incomplete or unstable frame.
Planned controls: Keep crane support until initial connections and required temporary stability are verified. Obtain the designated erection lead’s release; unrig from the planned protected position without standing beneath the beam.
Check before work: Lead communicates a deliberate release after verification.
066. Hand over for final bolting
Possible hazards: Unfinished connections or removed protection can mislead the next crew.
Planned controls: Identify connections awaiting final tightening and maintain frame stability and protection. Transfer completion limits to the bolting crew; do not treat wrench-tight initial bolts as final acceptance.
Check before work: Receiving bolting lead confirms unfinished-work records.
Example scope and starting conditions
A specialist steel crew will erect a solid-web beam between released columns and make its initial connections from protected access before releasing the crane. Final bolt tightening is a later operation. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- The erection sequence, column stability, connection details and crane support are established in current project documents.
- Conventional protected access is planned; no controlled decking zone, multiple-lift rigging, joists or double connection is included.
- Connector qualifications, applicable Subpart R fall protection and rescue arrangements are confirmed for the actual heights and roles.
Know when to pause
- Member, connection or erection sequence differs from the drawings.
- Column movement, unexpected beam response or lost access protection.
- Initial connection criteria cannot be achieved before crane release.
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
- Which connections and temporary stability conditions permit crane release?
- What protected positions keep connectors clear of the moving beam?
- Who confirms the beam matches the erection drawing before pickup?
Training and qualifications to confirm
- Connector and steel-erection fall training under the applicable Subpart R provisions.
- Actual initial connection and crane-release procedure, with applicable lift qualifications.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
Can this sequence be used for a shared-bolt double connection?
No. That operation has additional retention or seat requirements and needs its own engineered sequence. This bounded example deliberately excludes double connections and open-web joists.
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 erection bay
Hazard: An unstable column or wrong erection sequence can lead to frame collapse.
Control: Erection lead confirms column support, bearing points and the current beam sequence. Compare member marks and connection details with drawings; hold the lift for unresolved support or design changes.
Verification: Lead records the bay release before rigging the beam.
Why this belongs in the analysis: The new beam depends on the receiving frame’s stability.
2. Prepare connector access
Hazard: Falls, dropped tools or inadequate rescue access can expose connectors and crews below.
Control: Provide the specified protected work positions and task-specific fall arrangements under Subpart R. Secure tools, separate work below and confirm a practicable rescue plan before connectors enter.
Verification: Lead checks access and connector briefing before the lift starts.
Why this belongs in the analysis: A connection detail alone does not establish a safe work position.
3. Hoist and guide the member
Hazard: A rotating beam can strike or trap a connector.
Control: Use the lift plan and agreed signals; keep connectors outside the approaching member’s swing and pinch paths until controlled positioning is established. Use alignment tools without placing fingers in connection holes.
Verification: Signal person and connectors confirm stop communication at approach.
Why this belongs in the analysis: Guiding a beam is different from tightening a stationary connection.
4. Make initial connections
Hazard: Insufficient initial bolts can let the beam fall at crane release.
Control: Install the specified initial connection. For this solid-web beam, secure each connection with at least two drawing-size and strength bolts drawn wrench-tight, or the engineer-specified equivalent; follow any additional stability requirements.
Verification: Erection lead checks both ends against the drawings and applicable release criteria.
Why this belongs in the analysis: Final placing has a specific support-release gate.
5. Release crane support
Hazard: Premature unrigging can expose an incomplete or unstable frame.
Control: Keep crane support until initial connections and required temporary stability are verified. Obtain the designated erection lead’s release; unrig from the planned protected position without standing beneath the beam.
Verification: Lead communicates a deliberate release after verification.
Why this belongs in the analysis: A connector’s signal must represent completed checks, not schedule pressure.
6. Hand over for final bolting
Hazard: Unfinished connections or removed protection can mislead the next crew.
Control: Identify connections awaiting final tightening and maintain frame stability and protection. Transfer completion limits to the bolting crew; do not treat wrench-tight initial bolts as final acceptance.
Verification: Receiving bolting lead confirms unfinished-work records.
Why this belongs in the analysis: Initial connection and final bolting are separate stages.

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.
