Pipe Data Sheet Presented by David Joe Polly PE, PLS, WRE Senior Standards Engineer Roadway Engineering Unit
FHWA Audit dated September 2008 Finding #1 –ODOT is following Pipe and Culvert Selection Procedures that meet the final rule for SAFETEA_LU Section Finding #2 –Design life for all culverts can be increased to 75 years to conform to longer lasting pipe specifications.
Chapter 5 Recommendation from the audit… Add more culvert types to the Hydraulic Manual, so field changes can be minimized.
How do I fill out the Pipe Data Sheet?
Ignore pH and Resistivity…
What does a culvert failure look like?
Base thickness of pipes Thickness for Aluminum 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
