Soil Corrosion Mapping

We were retained by a major electric utility company to assist them in developing a corrosion risk assessment map for their service territory.  The genesis of this project started when they found severe below-ground corrosion on several steel structures after a short time in service.  Considering that they had several thousand structures across their service territory, the thought of inspecting each and every one of the structures would be a monumental as well as a costly task.  In consulting with Matergenics it was decided that the best way to approach this would be to develop a corrosion risk assessment map of their service territory.  The map would identify areas of high, medium and low below-ground corrosion risks.  Once the map was completed our customers were able to concentrate their resources on structures located in high corrosion risk areas.  The mapping effort has been completed and we have provided the client with a map in ArcGIS which they will put into their GIS system.  Customers are using the map for many things (operation, maintenance, geotechnical) with regards to other steel corrosion efforts.
