Catch Basin Structural Design
Catch Basin Structural Design
(OP)
I primarily design buildings but I have a precaster client that would like to reduce the amount of reinforcing in his DOT catch basins by way of engineering design. I am curious if anyone has experience doing this or ideas for references. He would like a stamp certifying that the reduced reinforcing is adequate, despite having less reinforcing than depicted on the standard drawing. It seems to be a common practice, nowadays.
It doesnt appear to be directly addressed in the AASHTO Bridge Spec but comes close in the buried structures section.
Any ideas?

One reason they don't like to deviate is that then they will have to review each deviation on its own merit.
That slows their process down (imagine that!) and they often don't have the technical expertise at a district level to do an appropriate review....so they tell everyone to make it like the standard details and don't throw a stick in the spokes.

My client has a very clear goal and is well aware of what they accept.

Also, California DOT has a section for underground structures in their "Bridge Design Practice Manual".
