Outline
• InspectTech
• New Jersey Turnpike Authority
• Bridge Inventory
• Need for Current System
• Basics of NJTA Inspection Report
• Features of New System
• New Possibilities
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.
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
NJTA Bridge Inventory
• ~1,000 total bridges – 498 (Turnpike) – 486 (Parkway)
• ~20M Sq.Ft. Deck Area – 15M Sq. Ft. (Turnpike)– 5M Sq. Ft. (Parkway)
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.
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
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
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
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
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

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
Summary Example
Category B “Contract”: Repair work by specialty contractor
Summary Example
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)
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.
Interactive Mapping
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
