Bridge Inspection Manuals
Bridge Inspection Manuals
(OP)
Other than local State and AASHTO publications, does anyone use or prefer a different manual that they have found better for inspections? If so, in what way(s)?
Particularly interested in smaller private bridge inspections rather than the RR or Highway versions.

Remember a bridge doesn't know if it's publicly or privately owned. In NYS ANY bridge on or over a public road is subject to the DOT's inspection requirements.
Mike, what sort of privately owned bridges are you looking at? Private or public, you still have to make sure it's safe for its intended purpose. Although for some private bridges your inspection might not have to be as rigourous as a highway bridge.
For example, a bridge leading from a public road to someone's house; perhaps the town has a requirement that it be able to carry a certain size fire truck. You probably wouldn't be overly concerned overly about the presence of fatigue prone details if the bridge is only carrying a few passesnger cars each day. On the other hand, if it's a bridge in a shopping center or some area that sees a lot of truck traffic it's a de facto highway bridge.

I know what you are saying BB, but I don't want to go overboard either. When I talk to the utility rep, I'll know more.

RE: Bridge Inspection Manuals
Generally for a bridge rehab project we do 100% hands-on inspection.
For a routine biennial inspection in NY we do a minimum 30% hands-on of the deck; 100% hands on of bearings; 100% hands-on of fatigue-prone details, fracture critical members, and non-redundant members; and stream bed measurements if applicable. It sounds like you might need less than a biennial by enough to CYA.
