NYDOT Bridge Inspection
NYDOT Bridge Inspection
(OP)
Hi,
Can anyone provide some insight as to why NY rates the worst of multiple elements for some elements (i.e. one bearing is a 2, while the rest are 6s, but the element rating is a 2) and does not rate the worst for other multiple elements?
Thanks in advance.

I agree with the potential for catastrophic failure on non-redundant older bridge configurations, of which NY has many. But in the case of new bridges, which commonly have high levels of redundancy and multiple load paths, I am not convinced that "rating the worst of" is beneficial.
Are you aware of any other DOTs that use this practice? I have done some looking and can not seem to find any other manuals that talk about it.
Thank you.
RE: NYDOT Bridge Inspection
I understand your point but there can't be two systems, i.e. one for old bridges and one for new bridges.
The is a certain method to the madness. By using a worst element rating the overall rating is lowered. Perhaps the idea is to keep the element on "the radar screen" so that it gets repaired quickly.
I've done bridge inspection in a few states and NY is the only one I've come across that uses this method.

I agree there can't be two systems and that tracking items that may lead to failures is crucial. I guess I am just a little confused as to why lighting standards and utilities are included on the "worst of" list. I understand the logic for the other items.
Thanks again.

CVG - there's a standard format for inspection reports. No final/supplemental reports are used.

If the case does exist that only SI&A data is collected for the inspection reports, then I would think the condition of the bridges would be hard to prioritize, as the BSR can be misleading.
RE: NYDOT Bridge Inspection
Inspection data is entered into a state-wide data base and from there each region can prioritize things.
