Trust but Verify “Post Installation Inspection (PII) of Storm Pipe”
Post Installation Inspection Acid Test for Installation Larger Diameters - Visual Inspection Small Diameters – CCTV Document Issues Location Defect Severity Measurements - Sketches – Photos Advanced Tools CCTV Laser Profiler Laser Crack Measurement
Where we Stand Today 2 of 3 of State DOT’s Require PII 1of 4 allow or require Advanced Inspection Tools www.concrete-pipe.org
PII is Sweeping Across the Country! WA OR ID MT WY UT CO NV CA AZ NM ND SD MN IA WI TX OK KS NE MO IL KY MI AR MS AL GA PA LA FL SC VA WV NY ME RI DE MD NC OH IN TN VT NH MA NJ CT AK Will post installation inspection become more prevalent? States shown in solid yellow have mandatory deflection inspection requirements. States shown in dashed blue, require or allow the use of laser profiling technology for post-installation inspection.
Impact of PII OWNER assumes a Trust but Verify Position Provides QA of Completed Installation Insures Owner getting what they Pay For Provides Confirmation of Structural Integrity and Hydraulic Capacity Has Greatly Reduced Risk for unanticipated Maintenance or Replacement Improved Quality of installations Reduces Lifetime Project Cost!
