I’m an old guy that is retired after 47 years in the construction industry. In my career, I have been responsible for the placement of thousand yards of concrete and the erection of thousand tons of steel. The $5.6 billion that President Trump is asking for to build his wall will not come close to covering the cost based on the scope of work that has been reported. Logistics alone will increase the cost measurable. If this wall gets built, stay tuned because the final cost will blow you away.
