Value Proposition Using Insight™
CMP assets.
repair/replace decisions in any size system using a tiered assessment approach based on condition, risk profile and replacement cost.
assets to optimize asset management by integrating with existing asset management system.
rehabilitations and safely deferring maintenance based on conclusive information.
validate grout placement, increasing rehab confidence and reducing risk

identify locations for follow up structural inspection with BCT
– Do I repair or replace? – Can I repair safely? – Can I differ maintenance? – How should I prioritize my asset maintenance?

Guelph Case Study Conclusion
Results
– Ceiling deformation – Isolated through wall perforations – Seam separations up to 4cm – backfill visible – Coating deterioration
– Largest anomaly approx. 2.25m horizontal – Some anomalies stretch above/below springline, indicative of surface water infiltration – Some anomalies are on both opposing walls (significant stress riser), possible localized soil weakness

MSD Case Study Conclusion
This work proved the ability to:

pipes
Based on this work, commercial deployment of Inversa’s Insight system is viable for both corrugated steel levee pipes and HDPE sliplined levee pipes for soil side voiding and grout placement verification.

How to Use Data
and necessitate costly replacement
repairs are cost effective and can extend life
failures despite money spent on repairs
growth annually to extend life
24
Conclusion
Visual and acoustic mapping alone cannot accurately quantify undermining. Current inspection methods can both under and over estimate the culvert condition. Asset integrity management and optimization increase safety and saves money.
With BCT you can:
1. Avoid costly replacements 2. Detect nonconformance early 3. Trend deterioration – repair only when necessary 4. Quantify necessary repairs 5. Increase safety and reduce maintenance costs 6. Repair voids prior to slip-lining 7. Verify grout placement post sliplining Therefore, you can confidently optimize asset lifespan with proper and necessary Asset Integrity Management.

– Involves bigger district commitment
– Change management

– Adds one-half FTE annually – District-level statistical significance (+/-7% at 95%)
– No longer negatively-skew LOS results
