Lessons Learned
• Account for setup time and mobility of hardware
• Communication between inspectors is essential
• Incorporate defect and general photos without
additional paperwork
• Interface requires some initial configuration to
tailor inspection forms to each bridge and
provide discrete elements for insertion of data
(repairs, deficiencies, ratings, etc.)

Recommendations
• Combination of existing technologies to create a
full-service bridge inspection and reporting
application
– Advanced Hardware (Smart Phone/Tablet)
– Integrated cameras with embedded GPS coordinates
and bearing
– 3-D Modeling Software for database
– Talk to Text applications

Inspection Software: Major Benefits
– Electronic collection: Reduces errors and eliminates
redundant data entry
– Picture Organization
– Integration of Manuals
– Easy incorporation of attachments
– Automatically pre-load past data
– Saves significant time by formatting the report and
auto-generating many sections:
• Table of Contents
• Cover Page
• Page Numbering

Report Review/Approval
•
•
•
•
•
•
Reports have full lifecycle and accountability
Tabs clearly show status of reports
Clearly documented who did the inspection
What changes were made
Who reviewed and when
Information not entered into official database
until it is approved
• Future: Auto-flag certain bridges for review
t
