Culvert footing design resources?
(OP)
I'm the project engineer on a highway project that will be replacing an 18' span 3-sided concrete box culvert. The stream bottom is bedrock.
I'm looking for a resource on designing the footings. Our state DOT's design manuals cover pretty much everything else, but they just say talk to the regional geotechnical engineer for footing design.
The problem is, the county I work for doesn't have a geotech. I want to make sure it's well out of my area of expertise before I start asking if we can pay for a geotech consultant, and if we do hire one, I want to know enough to make sure we're getting what we need.

If I add a clause requiring the proper PE stamp, does anyone have any objections to this? I'd be a lot more comfortable with that ... and a reference so I could check the shop drawings.

Also, if the culvert was designed for running water, increase the cover for the rebars, and provide extra concrete for expected erosion.

cvg, I's specifying state DOT design procedure for the culvert itself, but as I said, it's less than helpful regarding geotech. Is there anything in particular you'd recommend?

Do you still have any contacts at the regional office or GEB?
Do you have any soil data for a nearby project; sometimes it's a help?
