6. FHWA Audit dated September 2008 Finding #1 –ODOT is following Pipe and Culvert Selection Procedures that meet the final rule for SAFETEA_LU Section 5514. Finding #2 –Design life for all culverts can be increased to 75 years to conform to longer lasting pipe specifications.

7. Chapter 5 Recommendation from the audit… Add more culvert types to the Hydraulic Manual, so field changes can be minimized.

8. How do I fill out the Pipe Data Sheet?

10. Ignore pH and Resistivity…

11. What does a culvert failure look like?

13. Base thickness of pipes - 0.060 Thickness for Aluminum 0.064 Thickness for Steel Need– Design Service Life – Service Life based on pH and Resistivity values - Increase thickness or coat Corrugation size comes from the fill height tables RD380, RD382, and RD384

15. Its as easy as pie!
