Infrastructure such as gas and water mains. sewers. roads and bridges are vital building blocks for both the quality of life or individual citizens and for economic productivity ’of society’. Escalating maintenance costs and deteriorating servicability are 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 optinuzc 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 wall thickness of cast and ductile iron pipe. Together with advanced analysis software, the tool
will furnish engineers wiith 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.
