Construction Dust Monitoring UK | PM10 Boundary & TAP

Q: How much does construction dust monitoring cost?

A typical 12-month real-time PM10 monitoring scheme for a single boundary location (one MCERTS-grade monitor with met sensor, telemetry, monthly reporting and 24/7 alert handling) starts from around £6,000 to £9,000 plus VAT for the year. A two-location scheme with weekly deposited dust gauge readings adds approximately £4,000 to £6,000 per year. Short-term demolition-phase monitoring (typically 6 to 12 weeks) is from around £2,500 to £4,500 depending on the number of monitors and reporting frequency. We design the scheme to match the planning condition wording, not over-engineer it.

The monitoring scheme your planning condition actually requires

Most Medium and High Risk construction projects under the IAQM 2014/2024 construction dust framework end up with a planning condition or Section 106 obligation that requires real-time dust monitoring at the site boundary, plus deposited dust gauges at nearby sensitive receptors, throughout demolition, earthworks and the main construction phase. The wording typically references a Trigger Action Plan (TAP) with numerical action levels and a route for the local environmental health team to investigate exceedances.

Air Dust Odour designs, installs and operates these monitoring schemes for developers, principal contractors and demolition specialists across the UK. We supply MCERTS-grade real-time PM&sub10; and PM&sub2;.&sub5; monitors with telemetry, deposited dust gauges (Frisbee per Vaughan & Hall, Bergerhoff per VDI 2119, sticky pads per IAQM guidance), on-site weather stations, monthly compliance reports and 24/7 trigger alert handling. The scheme is designed to match the planning condition wording — not over-engineered.

Schemes are designed and signed off by Malcolm Pounder CEnv MIAQM, a Chartered Environmentalist and Full Member of the Institute of Air Quality Management. We will write the Trigger Action Plan, agree it with the local planning authority during CEMP discharge, install and maintain the equipment, deliver monthly reports, manage exceedance investigations and produce the final closure report — everything you need to discharge the condition.

What We Deploy

Monitoring Equipment & Methods

The IAQM framework is method-agnostic but specific about what it expects you to measure. Here is the typical loadout for a planning-conditioned scheme.

Real-time PM&sub10; / PM&sub2;.&sub5; Monitors

MCERTS-certified or equivalent optical/nephelometric/beta-attenuation particulate monitors with PM&sub10; and PM&sub2;.&sub5; channels, logging on 1-minute and 15-minute averages. Weatherproof IP65 enclosures, mains or solar/battery power, GSM telemetry pushing live data and exceedance alerts. Co-located with a met sensor for wind speed and direction to support source attribution.

Frisbee Deposited Dust Gauges

BS 1747-1 / Vaughan & Hall directional Frisbee deposit gauges read weekly or monthly, with gravimetric analysis to mg/m²/day. The IAQM 2014/2024 framework references 200 mg/m²/day as the headline exceedance threshold for nuisance dust at a sensitive receptor.

Bergerhoff & Sticky-Pad Gauges

VDI 2119 Bergerhoff gauges (where the local authority specifies them) and adhesive sticky pads (per IAQM guidance) read at the same locations as the Frisbees to give a comparative deposited dust record across two independent methods.

On-Site Meteorological Station

Calibrated wind speed and direction logger co-located with each PM monitor. Essential for source attribution — without met data, an exceedance cannot be defensibly attributed to or excluded from the construction site.

Trigger Action Plan (TAP)

The operational document that turns monitoring data into site actions. Tiered triggers (typical: 190 µg/m³ investigation, 250 µg/m³ action, 500 µg/m³ stop-works on 15-minute rolling PM&sub10;), notification chain to site management and environmental health, mitigation options at each trigger and an exceedance closeout protocol.

24/7 Telemetry & Alerting

SMS and email alerts to the project team within minutes of an exceedance. We provide out-of-hours alert handling so the site doesn\'t miss a trigger overnight or at weekends. Optional construction logbook integration to record concurrent on-site activity.

Monthly Compliance Reports

Concise monthly report with PM&sub10; / PM&sub2;.&sub5; time-series plots, deposited dust results against the IAQM 200 mg/m²/day threshold, wind rose, summary of any exceedances and the agreed mitigation response, and a forward look at the next month\'s programme.

Demolition-Phase Monitoring

Shorter-duration intensive monitoring schemes for the demolition phase, typically 6 to 12 weeks. Often a higher density of monitors and shorter reporting cadence (weekly or fortnightly) because demolition is the highest-dust phase of most projects.

When You Need It

Typical Project Triggers

Construction dust monitoring is required in any one of these situations.

IAQM Medium or High Risk classification Any project classified Medium or High Risk in the IAQM 2014/2024 dust assessment. Medium Risk typically catches residential schemes of 50+ dwellings or commercial of 10,000+ m² near sensitive receptors; High Risk catches major demolition and any works near an AQMA.

Explicit planning condition The most common driver. Discharge usually requires a Dust Management Plan (DMP) or CEMP, plus a Trigger Action Plan and a defined monitoring scheme agreed with the local environmental health team.

Section 106 / 278 obligation Larger schemes increasingly include dust monitoring in the S106 / S278 agreement as a binding obligation, sometimes with continuous monitoring through occupation rather than just the construction phase.

GLA London Plan / NRMM London developments above the GLA thresholds need a London Plan Air Quality Neutral assessment plus the NRMM Stage V compliance. Monitoring is often added as a CEMP condition where the predictive assessment flags residual significance.

Sensitive receptor proximity Schools, hospitals, care homes, residential property, ecological designations and food production sites within ~100 m of the works almost always trigger a monitoring requirement regardless of project size.

Complaints response Where works have already triggered dust complaints, monitoring is the way to objectively document conditions and either demonstrate compliance or identify the cause and target mitigation.

EP / IPPC / Permit conditions Quarry, aggregate, concrete batching and waste-handling permits routinely require ongoing PM&sub10; and deposited dust monitoring as a permit condition under EPR or the Industrial Emissions Directive.

Voluntary good practice For sensitive client groups (hospitals, schools, food production), boundary monitoring on a voluntary basis demonstrates due diligence and prevents disputes — usually a fraction of the cost of a single delay claim.

Our Process

Scheme Design to Closure Report

How a typical construction dust monitoring scheme is set up and run.

1. Condition review & scheme design We read the planning condition wording, identify what is actually required, and design a monitoring scheme that meets the wording at the right cost. We avoid the trap of over-specifying that some consultancies fall into.

2. Trigger Action Plan TAP drafted to match the project risk profile and the local authority\'s expectations. Trigger levels, notification chain, mitigation menu and exceedance closeout protocol all included.

3. LPA discharge package TAP plus monitoring scheme plus equipment specifications packaged for submission as a planning condition discharge application. We handle questions from the case officer or EHO and revise as required.

4. Installation PM monitors and met sensors installed at the agreed boundary locations, deposited dust gauges installed at the agreed sensitive receptor locations. Calibrated and commissioned on the day of installation, telemetry tested end to end.

5. Ongoing operation Continuous real-time data capture, weekly deposited dust gauge servicing, 24/7 alert handling, monthly compliance report, and a six-monthly site visit for cleaning, calibration check and equipment health review.

6. Exceedance investigation Where a TAP trigger is reached, we investigate the exceedance the same day — correlating PM data with wind direction, on-site activity log and any concurrent complaints — and document the cause, the mitigation deployed and the verification that controls have worked.

7. Decommissioning & closure report At the end of the monitored phase we decommission equipment, produce the closure report for the planning authority, and submit any final condition discharge package required.

Common Questions

Frequently Asked Questions

What is construction dust monitoring?

Construction dust monitoring is real-time, continuous measurement of airborne particulate matter (PM&sub10; and PM&sub2;.&sub5;) at the boundary of an active construction or demolition site, combined with deposited dust gauges at nearby sensitive receptors. It is used to demonstrate that dust generated by the works is being controlled to the levels specified in the IAQM 2014/2024 framework and the project Construction Environmental Management Plan (CEMP), and to provide objective evidence to discharge dust-related planning conditions.

When does a planning condition require construction dust monitoring?

Dust monitoring is normally required as a planning condition or Section 106 obligation on any project classified as Medium or High Risk under the IAQM 2014/2024 framework — typically Medium Risk for residential developments of 50+ dwellings or commercial sites of 10,000+ m² near sensitive receptors, and High Risk for major demolition, earthworks above 10,000 m², and any works close to AQMAs or residential property. The wording usually requires a Trigger Action Plan, real-time PM&sub10; monitoring at the boundary nearest sensitive receptors, and deposited dust gauges at named locations.

What instruments do you use for PM&sub10; boundary monitoring?

We deploy MCERTS-certified or equivalent real-time particulate monitors using optical scattering, nephelometry or beta attenuation principles, with PM&sub10; and PM&sub2;.&sub5; channels logging on 1-minute and 15-minute averages. Instruments are weatherproof, mains or solar/battery powered, and configured with GSM telemetry so live readings and exceedance alerts are pushed to the project team in real time. Each monitor is co-located with a wind speed and direction sensor so source attribution can be confirmed.

What is a Trigger Action Plan?

A Trigger Action Plan (TAP) is the operational document that sets numerical action levels for the dust monitoring data and defines what site management must do when a level is exceeded. A typical TAP has tiered triggers — for example a 15-minute PM&sub10; rolling average of 190 µg/m³ as an investigation level, 250 µg/m³ as an action level requiring works to be reviewed and additional mitigation deployed, and 500 µg/m³ as a stop-works trigger requiring works to halt until the cause is identified and controlled. The TAP is agreed with the local planning authority during CEMP discharge.

How much does construction dust monitoring cost?

A typical 12-month real-time PM&sub10; monitoring scheme for a single boundary location (one MCERTS-grade monitor with met sensor, telemetry, monthly reporting and 24/7 alert handling) starts from around £6,000 to £9,000 plus VAT for the year. A two-location scheme with weekly deposited dust gauge readings adds approximately £4,000 to £6,000 per year. Short-term demolition-phase monitoring (typically 6 to 12 weeks) is from around £2,500 to £4,500 depending on the number of monitors and reporting frequency.
