It's a start. How important are these types of details to what your are actually doing with this drawing? Is steel framing the focus of this drawing?

Yes it important it's a support for Piping.

Is there a tank or another piece of equipment going on that structure?

How were you planning to secure the piping to the structure?

Those piers look exceptionally high. Why is that?

Hi,

You can also use interfere checking for some steel frame intersection

Home Tab/Solid Editing panel/Interference Checking

Dont forget to uncheck delete interference object to keep it to substract after.
