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 Precast Building Beam Seat Erection JHA
Walk through the job in order. Use these possible hazards, planned controls and checks to start a conversation about your actual work.
011. Establish the beam and seat release
Possible hazards: An unready column corbel, incorrect beam or assumed bearing detail can leave a heavy horizontal member without the designed support or stability.
Planned controls: Erection lead identifies the beam, current erection design and actual seat-support release records. Obtain the responsible engineer’s bearing-pad, orientation and temporary stability requirements and confirm the planned pickup and crane-release hold points. Resolve revisions or missing support evidence before moving the member; keep permanent connections and subsequent loading separately assigned.
Check before work: Lead verifies beam, seats, current design and support-release evidence.
022. Prepare the receiving seats and protected crew positions
Possible hazards: Misplaced pads, debris, exposed access or people under the landing path can cause poor bearing, falls or crushing.
Planned controls: Crew prepares the seats and specified bearing components from the planned protected access, following the actual design. Check for damage or changed geometry and hold discrepancies for responsible technical review. Set the landing exclusion, communication and crew positions clear of pinch points; do not improvise stacked shims or alter a corbel to obtain fit.
Check before work: Lead checks seats, pads, protected access and landing exclusion.
033. Rig and lift the identified horizontal beam
Possible hazards: Incorrect pickup, twisting or workers guiding from a crush path can damage the beam or cause an uncontrolled suspended load.
Planned controls: Qualified rigging personnel use the beam’s accepted lifting points, equipment and orientation method, with the crane operator and assigned signal person following the planned lift. Complete required rigging and crane checks and keep people outside the suspended-load path except permitted essential erection roles under the applicable plan. Stop for unexpected beam response or lost communication.
Check before work: Qualified crew verifies pickup configuration and the controlled lift response.
044. Land on the designed bearing seats
Possible hazards: An uneven landing, trapped hand or incomplete contact can damage a pad, displace the member or leave an unstable beam.
Planned controls: Assigned crew directs the controlled landing from protected positions while the crane retains the prescribed support. Establish the beam orientation and bearing configuration through the actual design and permitted adjustment method. Keep hands outside closing gaps. Hold an offset, damaged component or unexpected fit for technical direction rather than forcing the member down or releasing the crane early.
Check before work: Observer reports required bearing and orientation findings to the lead.
055. Establish temporary stability before unrigging
Possible hazards: A beam resting vertically on seats may still roll, slide or move laterally when crane support is removed or later work begins.
Planned controls: Crew installs and verifies the temporary restraints and required connection-stage condition specified by the responsible erection design, while prescribed crane support remains. Erection lead obtains all required seat and stability findings at the actual crane-release hold point. Keep support in place if evidence is incomplete; do not substitute a visual impression of straightness or another beam’s bracing detail.
Check before work: Responsible personnel verify actual support and restraint before crane release.
066. Unrig and hand over the supported beam
Possible hazards: Removing a necessary restraint or assuming floor-load readiness can destabilize the member after the erection crew leaves.
Planned controls: After the actual release decision, qualified crew removes rigging through the protected method and checks for displacement or unresolved concerns. Record seat, pad and restraint findings and maintain the designed load and access restrictions. Transfer permanent connection work and later deck or floor loading to identified leads; keep temporary restraints under assigned control until their separate engineered release.
Check before work: Receiving lead confirms open connections, restraint ownership and load holds.
Example scope and starting conditions
A qualified crew will erect an identified horizontal precast building beam onto released column corbels or bearing seats. The actual erection design governs lifting, bearing pads and temporary lateral or torsional restraint before crane release. Permanent connections and floor loading are separately released. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- Beam, seats, current design, support release and lifting method are identified. The responsible engineer specifies bearing, pad configuration and temporary stability; no generic bearing length or shim recipe is supplied.
- Qualified lifting and erection personnel use protected access and verified exclusion and crane-release hold points. A column release alone does not release every beam seat.
- The precast column, beam and girder erection link 238120-24 is partial: horizontal building-beam erection onto released bearing seats only. Column erection, wall panels, hollow-core planks, bridge girders, field strand cutting and permanent connection completion require separate analyses.
Know when to pause
- Beam identity, current bearing and stability details or required seat-support release evidence are missing or inconsistent.
- Beam handling, seat geometry, pad condition or landing fit differs from the accepted design.
- Temporary restraint, protected access, exclusion, communication or the crane-release findings 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 actual records release the beam seats and their support structure for this identified erection load?
- How does the designed bearing and temporary lateral or torsional restraint remain effective before crane release?
- Who verifies the beam-specific support findings, and what later connections and floor loads remain held?
Training and qualifications to confirm
- Beam-specific precast erection and rigging instruction, including identified pickup points, orientation, communication and protected landing roles.
- Instruction on the actual seat, bearing-pad and temporary stability design, crane-release hold points and recognition of unexpected support or component conditions.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
Can floor planks be placed once the beam is unrigged?
Only after the separately required structural and erection release for those loads is obtained. This operation hands over a beam in its accepted erection-stage support condition with continuing restrictions. Permanent connections, temporary stability and the next loading sequence must follow the actual design; crane release alone is not evidence that floor construction may proceed.
What must the crew record for actual use?
Record beam and seat identities, design revisions, support-release basis, lifting roles and actual pad, bearing and temporary-restraint findings. Document crane-release evidence, responsible decision, fit or damage concerns, open connections and load holds; identify later restraint-release ownership without inventing support acceptance.

Task-by-task control and verification rationale
1. Establish the beam and seat release
Hazard: An unready column corbel, incorrect beam or assumed bearing detail can leave a heavy horizontal member without the designed support or stability.
Control: Erection lead identifies the beam, current erection design and actual seat-support release records. Obtain the responsible engineer’s bearing-pad, orientation and temporary stability requirements and confirm the planned pickup and crane-release hold points. Resolve revisions or missing support evidence before moving the member; keep permanent connections and subsequent loading separately assigned.
Verification: Lead verifies beam, seats, current design and support-release evidence.
Why this belongs in the analysis: Released columns do not automatically establish beam-seat readiness.
2. Prepare the receiving seats and protected crew positions
Hazard: Misplaced pads, debris, exposed access or people under the landing path can cause poor bearing, falls or crushing.
Control: Crew prepares the seats and specified bearing components from the planned protected access, following the actual design. Check for damage or changed geometry and hold discrepancies for responsible technical review. Set the landing exclusion, communication and crew positions clear of pinch points; do not improvise stacked shims or alter a corbel to obtain fit.
Verification: Lead checks seats, pads, protected access and landing exclusion.
Why this belongs in the analysis: Prepared bearings reduce intervention beside a suspended member.
3. Rig and lift the identified horizontal beam
Hazard: Incorrect pickup, twisting or workers guiding from a crush path can damage the beam or cause an uncontrolled suspended load.
Control: Qualified rigging personnel use the beam’s accepted lifting points, equipment and orientation method, with the crane operator and assigned signal person following the planned lift. Complete required rigging and crane checks and keep people outside the suspended-load path except permitted essential erection roles under the applicable plan. Stop for unexpected beam response or lost communication.
Verification: Qualified crew verifies pickup configuration and the controlled lift response.
Why this belongs in the analysis: Horizontal members require their own handling and stability plan.
4. Land on the designed bearing seats
Hazard: An uneven landing, trapped hand or incomplete contact can damage a pad, displace the member or leave an unstable beam.
Control: Assigned crew directs the controlled landing from protected positions while the crane retains the prescribed support. Establish the beam orientation and bearing configuration through the actual design and permitted adjustment method. Keep hands outside closing gaps. Hold an offset, damaged component or unexpected fit for technical direction rather than forcing the member down or releasing the crane early.
Verification: Observer reports required bearing and orientation findings to the lead.
Why this belongs in the analysis: Arrival alone does not prove the intended bearing condition.
5. Establish temporary stability before unrigging
Hazard: A beam resting vertically on seats may still roll, slide or move laterally when crane support is removed or later work begins.
Control: Crew installs and verifies the temporary restraints and required connection-stage condition specified by the responsible erection design, while prescribed crane support remains. Erection lead obtains all required seat and stability findings at the actual crane-release hold point. Keep support in place if evidence is incomplete; do not substitute a visual impression of straightness or another beam’s bracing detail.
Verification: Responsible personnel verify actual support and restraint before crane release.
Why this belongs in the analysis: Bearing and lateral or torsional stability require separate verification.
6. Unrig and hand over the supported beam
Hazard: Removing a necessary restraint or assuming floor-load readiness can destabilize the member after the erection crew leaves.
Control: After the actual release decision, qualified crew removes rigging through the protected method and checks for displacement or unresolved concerns. Record seat, pad and restraint findings and maintain the designed load and access restrictions. Transfer permanent connection work and later deck or floor loading to identified leads; keep temporary restraints under assigned control until their separate engineered release.
Verification: Receiving lead confirms open connections, restraint ownership and load holds.
Why this belongs in the analysis: Crane release does not release every later structural load.
Compare control wording
| Needs improvement | More useful for this scenario |
|---|---|
| Both ends are on concrete; unhook it. | Responsible erection personnel verify the actual bearing and temporary lateral or torsional stability requirements at the crane-release hold point. |
| Use whatever shims make the beam level. | Hold an unexpected fit and obtain the responsible engineer’s bearing and adjustment direction before changing the support arrangement. |
Common questions
