Environmental Assessment

Piling risk assessment

Government policy favours development on previously used land, commonly known as ‘brownfield’ sites. However, piling and penetrating ground improvement provides the potential to produce adverse environmental impacts when operated on land affected by contamination. In particular, on the potential for pollution of groundwater.

The Environment Agency have published technical guidance regarding the assessment of risks associated with, and preventing pollution from piling and penetrative ground improvement methods. The report outlines a process to allow designers to select an appropriate piling method and any mitigation and monitoring measures required.

The preparation of a foundation works risk assessment, and its examination by the regulators, is intended to help planning authorities in granting permission or enforcing planning conditions.
