3. Outline • InspectTech • New Jersey Turnpike Authority • Bridge Inventory • Need for Current System • Basics of NJTA Inspection Report • Features of New System • New Possibilities

4. InspectTech • Software company focused solely on developing high quality, easy to use, software for structure information • Proven flexible core system that allows on-site field and office access • Customize it for exact client needs • 40+ Clients: Federal Agencies (Navy/Marines, U.S. Fish & Wildlife), State DOT (Indiana DOT), Large Transit Systems (DC Metro), Toll Authority (NJTA), Counties, Cities (Baltimore, Philadelphia), Consultants, etc.

5. New Jersey Turnpike Authority • NJ Turnpike • Est. 1949, Opened 1951 • 148 miles long, 29 Interchanges • >251,000,000 vehicles 2007 • Garden State Parkway • Est. 1952, Opened 1956 • 173 Miles long, 359 Exits and Entrances • >439,000,000 vehicles 2007

6. NJTA Bridge Inventory • ~1,000 total bridges • 498 (Turnpike) • 486 (Parkway) • ~20M Sq.Ft. Deck Area • 15M Sq. Ft. (Turnpike) • 5M Sq. Ft. (Parkway)

7. The New Jersey Turnpike varies from two, two-lane roadways to up to six, three-lane roadways by Newark Airport, with dual-dual roadways for 32 miles through the busiest zone.

8. Need • Too many different databases • Difficult to maintain and update • Two different inspection formats from Parkway and Turnpike • Coordination with multiple consultants • Difficulty in retrieving/searching information (text and pictures) • Access based system not flexible

9. Solution Requirements • Proven system that could be tailored to Turnpike’s exact needs • Generate individual and summary reports • Single database to integrate all data • Easy to Learn and Use • Expandable (all structures) • Simplify consultant assignment, submission, review

10. Implementation • Worked with Turnpike and Consultants to customize BridgeInspect software • Pilot Project in mid-2007 (Part C – 5 bridges) • Full Implementation Jan. 2008 (All Turnpike and Parkway bridges) • Goals: • Enhance Quality • Save Time • Integrate all information • Seamless transition from old to new

11. Bridge Inspection Efforts • Part A, B, and C inspection contracts • Turnpike utilized a 7 Page “Checklist” format for the core of the report • Detailed Summary Reports generated by District • Excel Spreadsheets for quantifying conditions of main parts of bridge (BPS) • Compliance with FHWA NBI via NJDOT

12. Traditional Inspection Forms • Four Page Bullet forms with a traditional plan view schematic used for plotting lane arrangements, locations of spalls above and below deck, etc. by span/lane. (Pages 1-4) • Structure information section: used to describe the structure (Page 5) • Close-up inspection findings page: used to note the conditions of any major deficiencies found in the joint areas, abutment/pier supports/pads, and on bearing devices (Page 6) • Bearing device table: used to locate and emphasize deficiencies (Page 7) • New Page 8

23. Summary Reports • Done by Contract/Maintenance District • Classify needs according to Category • Category A “Emergency”: Immediate repair needed • Category B “Contract”: Repair work by specialty contractor (specialty equipment / materials) • Category C “Deck Repair”: Deck repair work by outside contractor • Category D “Maintenance”: Authority personnel, equipment, and materials • Category E “Monitor”: Minor defects/conditions that are slow developing or currently deferred

24. Summary Example Category B “Contract”: Repair work by specialty contractor

25. Summary Example

27. Centralized Information Source • Powerful new centralized source for all data • Turning all data into useful easy to retrieve information (tens of thousands of pages of data) • Accessible anytime from anywhere • Combining multiple data sources into single location • Inspection Data • Bridge Prioritization Program (Access/Excel) • Bridge/Culvert Inventory Files (Access) • NJTDOT NBI/Pontis Data (Text/PDI)

28. New Management Capabilities • Full Search Capabilities: Data can be viewed in table format or on a map • Alerts: Bridges with suspicious data can be quickly seen • Past information/trending can be viewed along with all supporting documents • All of the structure can be stored in one place • As-builts, memos, pictures, diagrams, load ratings, etc.

29. Interactive Mapping

30. Conclusions • Challenging project with many unique requirements • System well received by consultants • Enables a team approach between consultants and Turnpike • Turnpike/GEC now able to instantly get up-to-date data for important decisions • Long Term cost savings for inspection • Continuing to expand to support new Turnpike structures
