What it does

What the platform does

It prepares the application and the evidence behind it. You check it, sign it and send it to your council.

Noise predictions

Predicted levels at each property around your site from your plant list, worked out with the BS 5228-1 method and compared with the ABC thresholds in Annex E.

Impacted properties

Every address the search finds around your site, with its distance and whether the predicted level puts it over, near or under the limit.

Works, hours and noise steps

The works, the methods, the working hours and the steps you will take to keep noise down, which section 61(3) asks you to set out.

Documents for your council

The application, a noise assessment and schedules of plant and receptors, for you to check before you send them.

Assistant

Ask about Section 61 and BS 5228-1 while you work. Check its answers before you rely on them.
