What Does Matech Do?

• Provides metal fatigue monitoring systems for
  bridges
• Exclusive rights to 7 patents
• What our systems do
• Find fatigue cracks more accurately (and often
  earlier) than conventional means
• Divisions
• Highway Bridges (100,000 inspections/yr)
• Ready to perform final testing prior to taking
  products to the market

Bridge Inspection Division

• Why is more accurate (and earlier) fatigue
  detection in bridges
• important?
• Cracks at fatigue-critical locations can lead to
  catastrophic failures
• Can lead to more efficient utilization of
  resources
• For bridges, finding metal fatigue earlier leads
  to less expensive repairs,
• avoiding later traffic rerouting, delays other
  economic penalties.
• Avoids more expensive unnecessary secondary
  inspections, potentially saving governments
  millions!

What would it mean to commerceif this
bridge was suddenly posted to disallow heavy
vehicle traffic?

The Bridge Inspection Market
Number of Metal Bridges in US 200,000
Each must be inspected at least every two years
by federal law (ie, 100,000 mandated
inspections/yr) These inspections performed
by 200 inspection companies, or local
government agencies / bridge authorities And
how do you think they are inspected????

Bridge Inspection Methodology
And how do you think they are inspected???
A man on a ladder with a
hammer! i.e.,
visual inspection is primary The Federal
Highway Administration has said 56 of these
inspections are incorrect either by failing to
detect cracks and other structural flaws, or by
falsely reporting cracks or flaws.

C u r r e n t B r i d g eI n s p e c t i o n
P r a c t i c e s

• A visual inspection is performed
• If a defect is suspected gt A second in-depth
  inspection is performed
• using X-Ray, Ultrasound, Eddy Current, etc.
• T H I S I S E X P E N S I V E !
• 50 of the time, nothing was seriously wrong, so
  a second inspection was not necessary. Causing a
  waste of money and resources.
• Potentially catastrophic structural flaws are
  frequently not
• detected by visual-only inspections.
• Needed maintenance that can increase useful
  bridge lifetime or prevent
• catastrophic collapse will not be performed.

The Matech Solution for bridge inspection
The Electrochemical Fatigue Sensor (EFS) small
currents are detected, collected, processed to
document a crack as small as 1/200 inch (or to
determine no crack with HIGH confidence) EKG
on a Bridge Most of the research and
development of this technology produced under US
Government funding (8.3M over 5 yrs) Validated
in the lab by Rockwell Scientific Corp. in late
02, - funded by MATECH

E F S V a l u e P r o p o s i t i o nt o t h
e G o v e r n m e n t

• Screens out unnecessary false positive
  
• second inspections costing 20K or more
• Designed to detect imminent catastrophic failure
• Repair budget spent where really needed
• Flags bridges that truly need more frequent
  monitoring
• Can address bridges where heavy vehicles can lead
  to collapse

Matechs EFS Value Propositionto Bridge
Inspection Companies(For a Typical 2-3 Span
Bridge)

• Capital Expense 10K inspection kit (gt50 uses)
• Typical Variable Expense Cost per inspection
• 32 man hours _at_ 50/hr 1,600
• 100 in disposables, 1,000 in direct overhead
• 1,000 royalty to Matech
• Total variable cost 3,700
• MATECH ESTIMATES GOVERNMENT WILL PAY 10,000 FOR
  AN INSPECTION DONE w/EFS SYSTEM
• Since inspection is much better, and costs are
  avoided
• SEVERAL STATE DOTs INDICATE THIS COST IS VERY
  ACCEPTABLE

11
EFS Revenue ModelPrimarily from licensing of
the technology

• ROYALTY
• 1,000 per inspection
• (some additional profit from sale of kits and
  test consumables, too)

12
Matech Alliancesto promote adoption of EFS
technology

• We have good Washington DC and Pennsylvania
  political contacts
• US Committee for Bridge Safety
• A legislative effort to include the best
  available technology for bridge inspection
• Its goal to mandate use of EFS-equivalent
  technology
• Relationships with Departments of Transportation
• Penn DOT, Turnpike -- New Jersey
• California CALTrans
