When your crew makes an expensive mistake
A core hits a tendon in a post-tensioned slab. The crew says the planned scan was never booked, and the superintendent feels the urge to demand who forgot it. The immediate safety and technical response cannot wait for a blame argument.

Contain the affected work through the site's safety and technical procedures, then establish what failed in the preparation and authorization of the task. Keep the crew involved in a factual review and assign clear corrections. Leading without public blame does not remove accountability. It makes room to discover the missing control before the same task is released somewhere else.
- Activate the appropriate safety response and notify the responsible people immediately. Refer structural condition and safe access decisions to qualified professionals; do not direct the crew to investigate or improvise a repair.
- Preserve the factual record under the incident procedure. Identify the task, location, instructions, planned checks and people involved without altering evidence to make the sequence appear complete.
- Speak privately with the crew once the immediate response permits. Ask what information and authorization they had, which check they expected and what led them to start.
- Trace the handoffs with the project team. Separate an unassigned preparation task from a deliberate departure, and check whether the person releasing work actually verified readiness.
- Assign the approved corrective actions and a changed release control. Name who books, confirms and checks required preparations so the same gap cannot hide between two roles.
- Explain the learning and expectations to affected crews without exposing unnecessary personal detail. Verify the revised control on the next applicable task and follow through on any individual accountability through the proper process.
In British Columbia, WorkSafeBC's regulation requires reporting and investigation of unsafe conditions and limits emergency hazard exposure to the qualified, instructed workers needed. Follow the full applicable procedure; a management conversation cannot substitute for that response.
Common mistakes
- Demanding a public confession before the immediate response is complete.
- Calling the event 'carelessness' without checking task preparation.
- Promising the client a repair date before technical assessment.
- Replacing investigation with a general reminder to be more careful.
Checklist
After the immediate response
- Facts preserved
- Crew heard privately
- Preparation handoffs traced
- Technical decisions properly assigned
- Release control corrected
- Next comparable task checked
Check your understanding
The review shows two people each expected the other to arrange the prerequisite. What change would prevent a repeat?
