Engineers: Trump's wall could cost anywhere from $8bn to 40bn

Staff Writer |
The recently-signed executive order that calls for the construction of a wall along the U.S. southern border has created much talk and speculation regarding the cost of this mega project.

The purpose of this report is to investigate the conflicting cost estimates surrounding the project, by analyzing the cost of several design and construction options.

During the election campaign, Trump estimated that the cost of the wall will hover at $8-12 billion.

However, politicians and engineers challenged that figure as entirely unrealistic, not even covering the minimum predictable costs.

Furthermore, according to a February 9th publication by Reuters, a recent preliminary DHS internal document has stated that the project could cost as much as $21.6 billion, and take more than three years to complete.

Using the expertise gained by Homeland Security Research Corp. (HSRC) engineers from past border wall-fence consulting projects, HSRC engineers have created a detailed analysis of 4 wall-barrier design alternatives, ranging between:

- A maximum-cost concrete wall with multilayered security, 3,145km-long and 40ft-high, from the Pacific Ocean to the Gulf of Mexico, at a cost of $34.2 billion.

- A minimum-cost "photo op wall": a multilayered electronic security barrier, consisting of a 40km-long and 40ft-high concrete wall, as well as a 1,560km-long and 24ft-high fence, at a total cost of $6.2 billion.
