Overview

Contractors need to ensure all  necessary precautions to contain dust arising from excavations and construction works shall be taken to prevent a nuisance being caused to occupiers of buildings and properties in the vicinity of their works.

The Bergerhoff Method is described in the standards BS1747 Part 1: Methods for the measurement of air pollution. Deposit gauges, and VDI 4320 Part 2 Measurement of atmospheric depositions - Determination of the dust deposition according to the Bergerhoff method (the latter published by the German Engineering Institute).

Dust Deposition Rate is normally measured by gravimetrically determining the mass of particulates and dust deposited over a specified surface area over a period of one month (30 days +/- 2 days). The results are expressed as dust deposition rate in mass per unit area per day (mg/m2-day).

The Bergerhoff Gauge dust monitoring instrument is used on location and designed to measure for dust deposition, usually quoted as mg/m2/day.
