I found this on Facebook. It's an awesome explanation of what's wrong with Trump's Wall of Shame:
January 8 at 10:52 PM
I’m a licensed structural and civil engineer with a MS in structural engineering from the top program in the nation and over a decade of experience on high-performance projects, and particularly of cleaning up design disasters where the factors weren’t properly accounted for, and I’m an adjunct professor of structural analysis and design at UH-Downtown. I have previously been deposed as an expert witness in matters regarding proper construction of walls and the various factors associated therein, and my testimony has passed Daubert.
Am I a wall expert? I am. I am literally a court-accepted expert on walls.
Structurally and civil engineering-wise, the border wall is not a feasible project. Trump did not hire engineers to design the thing. He solicited bids from contractors, not engineers. This means it’s not been designed by professionals. It’s a disaster of numerous types waiting to happen.
