Location is Alabama and here all engineers are simply engineers whether electrical, mechanical, chemical, etc. Our certificates and stamps do not differentiate. But, we must practice only in areas of our experience and training.
Structural engineering is generally considered a specialty and engineers who want to practice that specialty often get their Masters Degree in Structural and have expertise primarily in that.
"General civil engineers", in my experience, tend to have expertise in a broader spectrum of civil engineering such as subdivision design, lift stations, site design, hydraulics and hydrology, roads/highways, etc., and don't do heavy structural design.
Back to the issue of my question:
The American Society of Civil Engineers in their Bridge Inspection documents define a series of culverts that measure 20 feet or more along the centerline of the road as a "bridge" with regard to inspections.
I know a "structural engineer" who is trained in Brige Inspection, who seems to hold the belief that culverts 20 feet wide along the centerline of the road must be designed by a structural engineer.
I am wondering if that is a commonly helf belief among engineers who do primarily structural engineering.
Thanks.
