Infrastructure such as gas and water mains, sewers, roads and bridges are vital building blocks for both the quality of life of individual citizens and for economic productivity of society. Escalating maintenance costs and deteriorating serviceability arc problems common to virtually every jurisdiction, presenting increasing engineering challenges for the management of aging assets. Effective planning, based on solid information about infrastructure condition, is essential to optimize capital reinvestment in renewing infrastructure.

Engineering research by a Canadian non-destructive testing company has yielded a new tool which provides continuous, direct measurement of the wall thickness of cast and ductile iron pipe. Together with advanced analysis software, the tool will furnish engineers with enhanced information to evaluate and manage their buried assets.

This paper provides background on remote field technology (the electromagnetic principle upon which the tool is based), describes the configuration and operation of the tool, and summarizes field trials conducted during the past two years.
