Hello
Expert:  StructuralEng replied 1 year ago.
I can help with this, to analyze both the decking and the beams, under a single set of conditions, but the question is significantly under priced. I would need to submit an additional service offer. Let me know if you would like to continue

I can't accept the phone cal offer or I will not be able to submit the additional service offer for the complete analysis of your bridge deck and beams

I am going to submit an additional service offer for you to consider to check the capacity for both the deck and the beams.
