Los Angeles, CA - June 27, 2007 -- Material Technologies, Inc. (OTC BB; MTTG.OB - News) ("MATECH") announced that the Utah Department of Transportation (UDOT) is in discussions concerning possible use of its patented Electrochemical Fatigue Sensor (EFS) technology to inspect bridges in the state. An EFS inspection was performed on a key bridge in the state last fall.

Of the state’s 840 steel bridges, 105 are considered structurally deficient and another 90 functionally obsolete. (Data as of year end 2006.) Each of these bridges must, by federal law, be inspected every two years, but if there are apparent problems the inspections may be more frequent. The potential annual revenue only from these structurally deficient and obsolete bridges from EFS inspections, at an average cost of $15,000 per inspection, competitive with other inspection technologies, could be about $1.46 million. The potential annual revenue from all the state’s steel bridges is $6.3 million.

The inspections are mostly visual, done by inspectors using binoculars. This is not an adequate means of inspection, since 90 percent or more of the cracks that are growing are completely missed with visual inspection alone, according to the Federal Highway Administration. For comparison the fifty states of the US as a whole have 190,000 metal bridges, with 39,000 structurally deficient and 35,000 functionally obsolete.

MATECH’s EFS measures the activity of growing cracks in metal bridges under ordinary traffic conditions, similar to the way an EKG monitors the heart.  It has proven a very reliable way to determine whether an observed crack in a metal structure is growing or not. A growing crack is an indicator of fatigue damage, and calls for a means of halting the growth by a repair or bridge member replacement or adding local support. A non-growing crack can be safely ignored.

Robert M. Bernstein, MATECH’s CEO says “MATECH has performed close to twenty field tests on actual highway and railroad bridges around the country, and we have every confidence that our EFS can save many repair and rehabilitation dollars by its timely use, as well as avoiding lane and bridge closures which can have a devastating effect on local commerce, not to mention avoiding potential tragedies of bridge failures.”

These potential EFS inspections will be used to demonstrate to UDOT officials the efficacy of using this technology on fatigue sensitive steel bridges to determine the status of known structural cracks, and to allow an estimate to be made of potential savings by using EFS to prioritize needed repairs. Its history and reliability in detecting growing cracks are well established.
