There are various locations along the border with some type structure built. They vary
in size, design, etc. If they were topped with razor wire it would be a deterrent for sure.

When the pre solicitation notice came out a month ago we had a lot of discussion on that thread. I updated it with links to the solicitations last night.

See
http://www.freerepublic.com/focus/news/3528799/posts?page=147#147

I also posted some of the basics from the concrete wall portion as I down loaded the specs which are about 140 pages for the preliminary proposal scope.

THE WALL

Basic Stuff from inside the documents:

Threshold Requirements
3

SOLID CONCRETE BORDER WALL DESIGN/BUILD IDIQ CONTRACT

1) The wall design shall be reinforced solid concrete.

2) 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.

3) 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.)

4) 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.)

5) The wall shall prevent digging or tunneling below it for a minimum of 6 feet below the lowest adjacent grade.

6) The wall shall prevent/deter for a minimum of one (1) hour the creation a physical breach of the wall (e.g., punching through the wall) no 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.

7) 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.

8) The wall design shall be able to accommodate surface drainage.

9) 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).

10) The wall design shall be constructible to slopes up to 45 percent.

11) The wall fittings and fixtures shall be secured on the north side of the wall to shield from external attack.

12) The wall design should be cost effective to construct, maintain and repair.

Objective Requirements

1) 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 one (1) hour up to 4+ hours the creation of a physical breach of the wall (e.g., punching through the wall) no 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.

C.3.4.2 Mock-Up Construction

The Contractor shall design and construct a 10 ft. by 10 ft. mock-up of an exemplar section of its prototype at a location in San Diego, CA as determined by the Government. The mock-up shall replicate the structural design of the prototype’s first 10 ft. of above ground wall height (measured from the adjacent ground) and length to allow the Government to test and evaluate the anti-destruct characteristics of the bidder’s wall design. The mock-up shall meet all technical requirements except the anti-dig, anti-climb, and aesthetics. The anti-dig and anti-climb characteristics will not be tested with the mock-up. The modified above ground foundation shall not affect the criteria outlined in specifications below.

The mock-up shall include the following requirements from section C.3.1 of this Statement of Work:

1) The Contractor shall build the mock-up to reflect the maximum performance contained within the prototype design (i.e., between 1 hour and 4+ hours).

2) The wall fittings and fixtures shall be secured on the north side of the wall to shield from external attack.

4
SOLID CONCRETE BORDER WALL DESIGN/BUILD IDIQ CONTRACT

3) If the prototype wall design includes see-through component/capability
then it shall be installed in the mock-up to test its anti-destruct capabilities
The mock-up shall be constructed within two (2) weeks after notice to proceed (NTP) and shall be constructed concurrent to prototype construction. Within seven (7) calendar days of notification of completion of mock-up evaluation, the Contractor shall remove the structure and dispose of it properly. Disposal includes site clean-up after testing has concluded.
