Point of Work Risk Assessments
During construction, before work began, a point of work risk assessment had to be completed for a task, an environment or an interface.
50 supervisors were asked to complete a ‘PoWRA’ online form to track any changes. If there was no change, the form would say proceed. However, if there was a change, there would need to be a more formal logging of the changes via the form below. The form would go through the following:
- There must be a new briefing before any further work starts.
- There must be evidence provided regarding any damage, location, time and photos of the what was causing the change.
- The form would need answers to questions about which task is occurring to correlate it with the PoWRA.
- All briefings were logged.
- Every company on site was logged.
If the change could be made without affecting the risk of the work, the change and control measure could be written onto the Task Briefing Sheet change section. Once done it had to be briefed to the operatives carrying out the work who would sign the briefing sheet.
Here’s how the form worked
The final stage required the change section and sign off sheet to be captured on the form below and submitted electronically:
All submitted changes formed a grid report that was searchable.
This system was reliant on the handwriting being legible and a decent photo having been taken. People also needed to sign the attendance sheet as capturing attendance was not possible on the ‘Jotform’ platform used.

Month of September 2018 dashboard data from London Bridge:
This was set up so that the submitting person received a copy in PDF form proving that they completed it. The system could be configured to email the relevant engineers if a change was selected so that they were aware of that change and could review the Task Briefing Sheet (TBS) / Works Package Plan (WPP) / Safe System of Work (SSOW) and include it in the updated revision.
Below is a screenshot of the daily dashboard from a specific day.
- A log of people completing briefings was also needed as this was not captured on the system.
- Changes and valid comments recorded needed to be fed back round to correct the original briefing and risk assessment documents.
