B3 control report – documenting completed checks

Where the B2 control plan sets out what needs to be checked, the B3 control report documents that it actually happened. The report follows the control plan's points one by one and records when the check was carried out, who carried it out, and what the result was.

The report isn't a one-time document - it's built up progressively, as the control points from the B2 plan are completed on site.

For every control point in the B2 plan, the B3 report needs to show the date of the check, who carried it out, and a clear result - approved, or a deviation with a description of how it was handled.

If a control point from the B2 plan is missing from the B3 report, a gap appears in the documentation that the structural engineer typically catches late in the process - often closer to handover, when it's more expensive to fix.

Most projects we take over midway are missing exactly this - an up-to-date B3 report. It usually happens because responsibility for documenting the control is spread across several people on site with no single overview. We fix that by keeping the documentation in one place and following up progressively as the work moves forward.

We build and maintain the B3 control report throughout the construction period, matched against your B2 plan, so you can always show how far the control has progressed. If there are gaps in an existing report, we catch up and close them before handover.
