User guide for the Corroded Asset Failure : Ferrous map

Ferrous (iron) structures and pipelines are susceptible to surface pitting and corrosion, which weaken assets and increase the potential for failure. Such assets are more prone to failure where ground movement occurs due to the change in stress around the asset. This user guide describes the Corroded Asset Failure - Ferrous map, which has been developed by the BGS to help identify where the condition of underground iron assets such as pipes, cables and building foundations may be compromised. The dataset indicates where corroded assets may exist, and where ground stability may result in asset failure. This data is intended for asset managers who are responsible for assessing the condition of underground iron assets. In particular, the data may be useful for water companies who need to determine where leaks may occur in the pipe network. The data may be used to prioritise maintenance to help meet leakage reduction targets in a cost effective manner. In addition, the data may be useful at the desk study stage for selecting pipeline routes or to identify appropriate construction materials.
