How does boundary dust monitoring work?

Boundary dust monitoring involves placing specialist equipment along the perimeter of a construction site to measure airborne particles leaving the site. These monitors run continuously and record dust levels in real-time, so we can see when dust rises due to certain activities — like demolition, concrete cutting, or dry sweeping.

The data usually includes PM10 and sometimes PM2.5, which are tiny particles that can be breathed deep into the lungs. The system sends alerts if levels exceed agreed limits, allowing contractors to pause work or improve dust control measures.

It’s a practical way to show a council or client that dust is being managed and that the project isn’t affecting nearby homes, schools, or businesses.
