Construction Dust Monitoring

Why Construction Sites Need Continuous Dust Monitoring

Construction dust is one of the most heavily regulated environmental impacts in the UK. The Institute of Air Quality Management (IAQM) Guidance on the Assessment of Dust from Demolition and Construction (2014, updated 2023) requires every developer to assess dust risk and implement monitoring where the site is classified as medium or high risk. For sites within 350 metres of sensitive receptors — schools, hospitals, residential properties — continuous boundary monitoring is increasingly a planning condition rather than a recommendation.

The IAQM defines the critical PM10 action level at 190 µg/m³ as a 1-hour mean at the site boundary. Exceedance can trigger enforcement action, neighbour complaints, and project delays costing thousands of pounds per day. Sites must also track PM2.5 for health-related assessments, particularly near residential receptors.

For a comprehensive overview of particulate matter in the UK — including PM2.5 and PM10 health effects, legal limits, and measurement methods — see our monitoring guide.

MCERTS-Certified Dust Monitoring with the Sensorbee Particle Module

The Sensorbee Particle Matter Module (SB4102) is MCERTS-certified for PM10 and PM2.5 indicative ambient monitoring (Certificate No: CSA MC250462/00). It plugs into the Air Pro 2 station and measures PM1, PM2.5, and PM10 simultaneously with:

• Resolution — 1 µg/m³
• Measurement range — 0–1,000 µg/m³ (linear up to 1,400 µg/m³ per peer-reviewed validation)
• Heated inlet — activates above 60% humidity to prevent false readings from fog and condensation that plague uncorrected sensors on exposed sites
• Factory calibration — every sensor individually 3-point calibrated against reference standards, shipped with its own calibration certificate

Key dust monitoring capabilities:

• Real-time boundary monitoring — continuous PM10 and PM2.5 readings at sensitive receptor locations
• Automated threshold alerts — configurable SMS or email warnings before IAQM action levels are breached
• MCERTS-certified data — measurements accepted by the Environment Agency, local authorities, and planning inspectors
• Audit-ready logging — timestamped records with 1-minute resolution for regulatory submission and dispute resolution

Dust data from the Sensorbee cloud platform exports directly into Section 61 compliance reports, providing the evidential chain that planning authorities require.

How It Works on Your Construction Site

1. Deploy at sensitive receptors — mount the Air Pro 2 with the MCERTS Particle Module at each boundary location defined in your dust management plan. Connect the solar panel and the unit begins transmitting data immediately via NB-IoT or LTE-M.

2. Set IAQM-aligned thresholds — configure alert levels in the Sensorbee cloud platform: the IAQM 190 µg/m³ PM10 action level, planning-condition limits, and any project-specific receptor sensitivity bands.

3. Monitor and respond in real time — view live readings on a single dashboard. Receive automated alerts the moment PM10 approaches its threshold, giving site managers time to implement dust suppression — water bowsers, screening, modified work methods — before a breach occurs.

4. Report with confidence — generate audit-ready compliance reports with timestamped, MCERTS-certified data. Export directly for Section 61 submissions, planning authority reviews, or community liaison meetings.

Where We Deploy

• Site perimeters — boundary monitoring at sensitive receptor points defined in your dust management plan
• Demolition zones — high-dust activity tracking during heavy works with real-time PM10 alerting
• Excavation areas — dust suppression monitoring during earthworks and material handling
• Haul roads — vehicle-generated dust tracking along transport routes
• Residential boundaries — combined dust + noise and vibration monitoring at homes near sensitive works

Construction dust monitoring on urban projects often intersects with broader urban air quality monitoring duties, particularly near Clean Air Zones where roadside PM and NO₂ are already elevated.

Frequently Asked Questions

What dust monitoring is required on UK construction sites?

The IAQM Guidance on the Assessment of Dust from Demolition and Construction requires a dust risk assessment for every site. Medium and high-risk sites — typically those within 350 metres of sensitive receptors — need continuous PM10 monitoring at site boundaries. Many local planning authorities now make MCERTS-certified monitoring a condition of consent. The critical action level is 190 µg/m³ PM10 as a 1-hour mean.

Do I need MCERTS-certified dust monitoring?

MCERTS certification is not universally mandatory, but it is increasingly required by planning conditions and Environment Agency guidance. MCERTS-certified data carries significantly more weight in regulatory proceedings and dispute resolution. The Sensorbee Particle Matter Module is MCERTS-certified (Certificate No: CSA MC250462/00) and validated against the reference-grade Fidas 200S system at the London Teddington Bushy Park monitoring station.

Can the sensor handle high-concentration dust events?

Yes. Peer-reviewed validation shows the Sensorbee Particle Module remains linear up to 1,400 µg/m³ PM10 — far above the standard 190 µg/m³ action level — so dust spikes from demolition or earthworks are captured accurately, not clipped.

How does Sensorbee handle humidity and fog?

The MCERTS Particle Module has a heated inlet that activates above 60% relative humidity, preventing the false positives that plague uncorrected optical particle counters in foggy, damp, or condensing conditions common on UK construction sites.
