First, describe the work and worksite
A specialist restoration crew will install an engineer-issued helical-bar crack-stitch repair into retained ground-level brickwork using specified bed-joint slots and compatible cementitious grout. The cause of cracking and wall stability are independently reviewed before work. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- The actual repair design identifies bar and grout system, slot locations, embedment, termination and acceptance requirements.
- The retained wall and any required temporary support are released; approved cutting, cleaning and chemical controls are prepared for the identified materials.
- Crack diagnosis, unsupported walls, movement-joint bridging, masonry rebuilding and substituting a general tuckpointing detail are excluded.
Questions before work
- What diagnosis and design release this crack for reinforcement rather than another remedy?
- How are slot locations and actual bar/grout components verified before cutting?
- What records, curing restrictions and acceptance criteria govern the completed repair?
Build the analysis one step at a time
What will the worker do? How could someone be harmed? What prevents or reduces that exposure? Who checks the control, and when?
1. Release the diagnosed repair
Hazard: Stitching an active movement joint or unstable wall can conceal an unresolved structural problem.
Control: Restoration lead checks the engineer’s diagnosed cause, stability/support release and bar layout. Confirm the permitted masonry and service/material clearance; do not assume every visible crack should be reinforced or use the product brochure as a repair design.
Verification: Lead compares the mapped crack and slots with the current issued repair.
Why this belongs in the analysis: The repair follows diagnosis rather than choosing a product from crack appearance.
2. Arrange access and slot controls
Hazard: Cutting and cleanup can expose workers or bystanders to silica and flying debris.
Control: Separate the ground-level work bay, protect adjacent surfaces and prepare the approved slot-cutting and cleaning equipment. Establish task-specific silica controls, assessed protection and the planned waste route; keep any required wall supports protected.
Verification: Lead verifies tools, dust controls and stable positions before cutting starts.
Why this belongs in the analysis: Joint preparation remains an exposure even when the finished repair is concealed.
3. Cut and inspect specified slots
Hazard: An overcut or unexpected void can damage retained units or a concealed service.
Control: Cut only the design-marked locations and dimensions by the approved method with exposure controls functioning. Stop for unsuitable masonry, unexpected reinforcement or a conflict with an opening; have changed slot conditions technically resolved before continuing.
Verification: Installer records actual slot geometry and any changed substrate condition.
Why this belongs in the analysis: A deeper or longer slot is not an automatic improvement to the repair.
4. Clean and prepare the repair grout
Hazard: Residue or incompatible grout can prevent the intended reinforcement bond; wet cement can injure skin.
Control: Use the selected system’s slot-cleaning, substrate-conditioning and grout preparation instructions. Keep dust controlled, identify actual materials and use assessed eye and cement-contact protection with washing access. Do not substitute ordinary pointing mortar or add unapproved water.
Verification: Installer checks slot readiness and grout identity before reinforcement placement.
Why this belongs in the analysis: The bar and its specified grout work as a repair system.
5. Embed the specified reinforcement
Hazard: A misplaced bar, insufficient encapsulation or sharp end can cause injury and incomplete repair.
Control: Install the design-specified bars, laps and terminations using the actual grout placement sequence. Keep hands clear of sharp ends and verify embedment before finishing conceals it; protect the repair against movement or loading during required curing.
Verification: Lead records actual reinforcement and grout findings at the concealed-work hold point.
Why this belongs in the analysis: Repointing the face cannot demonstrate correct hidden reinforcement.
6. Protect cure and transfer acceptance
Hazard: Early disturbance or an undocumented repair can mislead later crews about wall condition.
Control: Complete the specified finish, collect waste by the approved method and maintain support and curing restrictions. Transfer actual locations, product records, installation findings and unresolved actions for designated acceptance; no example establishes restored structural capacity.
Verification: Receiving lead confirms restrictions and the acceptance record or remaining hold.
Why this belongs in the analysis: A concealed neat repair supplies no automatic structural signoff.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Work carefully and wear PPE. | Cut only the design-marked locations and dimensions by the approved method with exposure controls functioning. Stop for unsuitable masonry, unexpected reinforcement or a conflict with an opening; have changed slot conditions technically resolved before continuing. |
| Check that everything is ready. | Restoration lead checks the engineer’s diagnosed cause, stability/support release and bar layout. Confirm the permitted masonry and service/material clearance; do not assume every visible crack should be reinforced or use the product brochure as a repair design. |
Decisions that change the analysis
Is ordinary tuckpointing an equivalent repair for this crack?
No. Tuckpointing renews mortar joints. This issued repair installs reinforcement across a diagnosed crack in retained masonry; neither that distinction nor a product claim proves the repair is appropriate for another wall.
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.
Agree when the crew will pause
- The crack, movement joint or wall condition differs from the diagnosed repair.
- Slotting reveals unsuitable material, services or an unapproved geometry change.
- Bar/grout compatibility, concealed verification or curing protection is unresolved.
After a pause, correct the condition, reassess the work, and obtain required authorization before restarting. Keep unresolved actions visible.

Training needs to confirm
- The actual engineer-issued crack-stitch layout, selected bar/grout system and concealed-work acceptance sequence.
- Task-specific silica controls, slotting-tool instruction and wet-cement/contact protection for the repair materials.
Confirm applicable qualifications, task instruction and actual training evidence for the people assigned. Related toolbox talks support toolbox talks; they do not establish competence.
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.
