Structural Health Monitoring
• Start with a “GPS/IPS”(inclinometer positioning system) sensor system to clarify initial structural health concerns
• Additional sensor types can then be strategically added in suspect locations
• Structural engineers, using state-of-the-art analytics, can develop a final diagnosis quickly and efficiently with information from our sensor systems
• A definitive diagnosis leads to development of structure specific remedies and optimized Asset Management programs

2009 ASCE Report Card for America’s Infrastructure
Almost 27%, or more than one in four, of the nation’s bridges are considered structurally deficient or functionally obsolete. In real numbers, this means that of the 600,905 bridges listed by the U.S. Department of Transportation inDecember 2008, 72,868 (12.1%) were categorized as structurally deficientand 89,024 (14.8%) were categorized as functionally obsolete. Even thoughthe number of deficient rural bridges declined by 8596 from 2005 to 2008,the number of deficient urban bridges increased by 2817 during the same time period. Considering the higher level of passenger and freight traffic on these urban bridges, the impact is significant.
•72,868 (12.1%) structurally deficient•89,024 (14.8%) were categorized as functionally obsolete.
•One in four, (1/4) count your bridges every 4th one could fail.
