OLD METHOD

CableScan™ No lane closures with daytime inspection

Eliminates need for boom trucks

More accurate than traditional inspection methods.

Safer for both the inspector and the public.

Uses LIDAR to measure length and width of cracks.

Double blind study of an inspection of 84 cables found 1 issue with traditional method. IPC’s QC of 9 cables found 12 issues.

Recorded video file for future comparisons.

CableScan™

https://youtu.be/LAuZhN1Z_yE

Digital images of elevations ranging between 150 to 300 ft.

Magnificati on of what was detected

Sample of Failed clear laminar rust coat / UV beneath coating coating

Paintedover gouges due to man lift damage

Damage due to scaffolding standoff bars

Highlighted Service CrackScan™ 

Scans for cracks from over 100 feet away



No Lane closures



No boom lifts required



More efficient, less expensive and more accurate than current inspection methods



Records X and Y coordinates of the cracks as well as length and width



Future inspections allow the asset manager to track crack progression over time



Double blind study of 2 bridges in Nevada where the engineering firm showed no cracks on 1 bridge and none on another 

IPC located 7 cracks on one and 6 cracks on the other



Manual methods cannot compete with laser technology

Wando River Bridge Post Tension Tendon Assessment

PROJECT Tendon condition assessment

CLIENT HDR Engineering

IPC ROLE Condition assessment of Tendon to determine extent of corrosion due to age of bridge

Problem Solved Loose and failed tendons led to concern of condition of tendon system.

IPC solution included magnetic flux in lieu of ECT, which produced misleading results. MF result led to fewer invasive examinations from open tendon
