Changes to Construction Guidance

The IAQM Guidance on the assessment of dust from demolition and construction has been updated to reflect inconsistencies in Table 3: Sensitivity of the Area to Human Health Impacts.
  1. In the original table there was no differentiation for medium sensitivity receptors based on the annual mean PM10 concentration, which lead to some inconsistencies. The table now makes it clear that where the local annual mean PM10 concentration is less than 28 µg/m3 the surrounding area will have a low sensitivity to health effects during demolition and construction works.
  2. A further change was made for the low sensitivity receptors to include one or more receptors. Previously it only applied where there were more than one receptor.
