Since the collapse of the I-35W bridge in August 2007, bridge health monitoring has become an area of intense
interest. This report defines terminology related to bridge health monitoring and provides a general glossary of
available monitoring systems. The glossary is meant to help readers make an informed decision by understanding
how different systems function and their strengths and weakness. The authors developed a questionnaire to send to
commercial companies offering monitoring systems. Of the 72 questionnaires that were sent to commercial
companies, 38 companies responded and are included in this report. From information provided with these
questionnaires, available commercial systems are briefly summarized. Criteria for system evaluation were
developed to help the bridge owner narrow down company choices for bridge application. After the owner answers
a set of questions pertaining to a particular bridge, a program developed in Microsoft EXCEL helps the bridge
owner decide the best system for a particular situation. An example is provided for program clarity. Once
company choice is narrowed down, additional criteria were developed to aid in final product choice.
