While on the campaign trail, President Trump promised to build a “big, beautiful wall,” on the southern border with Mexico. Many are pleasantly surprised that this was not just a campaign promise.

“I will build a great wall — and nobody builds walls better than me, believe me –and I’ll build them very inexpensively. I will build a great, great wall on our southern border, and I will make Mexico pay for that wall. Mark my words.”
Proposals are now being solicited to build the wall that is listed on the fedbizopps.gov website. The proposals must be submitted by March 29, 2017.
The border wall “shall be physically imposing in height,” (between 18 and 30 feet tall), go six feet into the ground, and be aesthetically pleasing from the north. We now know that the government prefers solid concrete, but other materials will be considered. It must be built so that it cannot be penetrated easily by a “sledgehammer, car jack, pick axe, chisel, battery operated impact tools, battery operated cutting tools, Oxy/acetylene torch or other similar hand-held tools,” so that attempts to get through may be thwarted by guards. There will also be automated gates to allow authorized passage.
Contractors will build 30 foot-wide sample sections in San Diego. The prototypes will cost $200,000 to $500,000. The wall must blend into the landscape. It must be impossible to use a ladder to climb over and be difficult to use grappling hooks to scale.
The threshold and objective requirements from the government are below:
1) The wall design shall be physically imposing in height. The Government’s nominal concept is for a 30-foot high wall. Offerors should consider this height, but designs with heights of at least 18 feet may be acceptable. Designs with heights of less than 18 feet are not acceptable.
2) It shall not be possible for a human to climb to the top of the wall or access the top of the wall from either side unassisted (e.g. via the use of a ladder, etc.)
3) The wall design shall include anti-climb topping features that prevent scaling using common and more sophisticated climbing aids (e.g. grappling hooks, handholds, etc.)
4) The wall shall prevent digging or tunneling below it for a minimum of 6 feet below the lowest adjacent grade.
5) The wall shall prevent/deter for a minimum of 30 minutes the creation a physical breach of the wall (e.g., punching through the wall) larger than 12-inches in diameter or square using sledgehammer, car jack, pick axe, chisel, battery operated impact tools, battery operated cutting tools, Oxy/acetylene torch or other similar hand-held tools.
6) The north side of wall (i.e. U.S. facing side) shall be aesthetically pleasing in color, anti-climb texture, etc., to be consistent with general surrounding environment. The manufacturing/construction process should facilitate changes in color and texture pursuant to site specific requirements.
7) The wall design shall be able to accommodate surface drainage.
8) The wall design shall be able to accommodate Border Patrol approved design standards for pedestrian and automated mechanized vehicle sliding gates (25 feet and 50 feet).
9) The wall design shall be constructible to slopes up to 45 percent.
10) The wall fittings and fixtures shall be secured on the north side of the wall to shield from external attack.
11) The wall design should be cost effective to construct, maintain and repair.
1) Incorporating a see-through component/capability to the wall that facilitates situational awareness but does not negate the requirements listed above is operationally advantageous.
2) It is operationally advantageous that the design of first 12 feet of wall height (as measured from the highest adjacent grade) be adaptable to prevent/deter for a period of time greater than 30 minutes up to 4+ hours the creation of a physical breach of the wall (e.g., punching through the wall) larger than 12-inches in diameter or square using sledgehammer, car jack, pick axe, chisel, battery operated impact tools, battery operated cutting tools, propane or butane or other similar hand-held tools.
