Paper Abstract

Construction is the largest industry in the world, amounting to 10% of the world's gross domestic product. Civil infrastructure systems are generally the most expensive investments/assets in any country. In the U.S. it is estimated at 20 trillion dollars. In addition, these systems have long service life compared with any other kinds of commercial product and are rarely replaceable once they are erected. Yet the feedback and controls ont he 'state of health' of constructed systems are practically nonexistent. Nondestructive evaluation is an essential part of this feedback and monitoring systems for infrastructures. NSF and NIST NDE initiative as well as workshops and recent awards/projects are described in this paper.
