Barrier fencing system

1. A barrier fencing arrangement for controlling passage both above and below a ground surface, comprising:

a plurality of foundation members positioned at least partially below the ground surface, each of the foundation members having a body with a top portion and at least one fin extending from the body, the at least one fin being substantially coplanar with at least one fin of each adjacent said foundation member, the fins extending a similar distance away from their respective foundation members;

a plurality of extension members, each of the extension members attached to or integral with the body of a respective said foundation member and extending from the top portion of the foundation member at least partially above the ground surface;

a fence arrangement, comprising a plurality of adjacently positioned fence panels disposed on the plurality of extension members, wherein the fence panels extend between adjacent extension members to block passage above the ground surface, wherein the coplanar fins of each pair of adjacent foundation members substantially span the distance between the adjacent foundation members to block passage below the ground surface beneath each fence panel; and

at least one access portion formed in at least one said fence panel, the access portion having a width and configured to selectively permit access through the fence arrangement;

wherein one of the fins extending from a foundation member associated with an extension member having a fence panel with an access portion disposed therein extends, toward a coplanar fin of an adjacent said foundation member, underneath and at least a distance equal to the width of the access portion.

2. The barrier fencing arrangement of claim 1 , wherein each foundation member further comprises a bearing plate attached to the top portion thereof, and a respective extension member attached thereto, wherein the bearing plate is configured to contact the ground surface.

3. The barrier fencing arrangement of claim 1 , wherein at least one of the body of each of the foundation members and the extension members is at least partially filled with a material.

4. The barrier fencing arrangement of claim 1 , wherein the fence arrangement comprises:

at least one sleeve member positionable at least partially over a respective extension member;

a bracket assembly attached to and extending from a surface of the sleeve member; and

a fence panel attached to at least a portion of the bracket assembly.

5. The barrier fencing arrangement of claim 1 , wherein at least two adjacently positioned fence panels are directly or indirectly attached to at least one of a respective foundation member and a respective extension member.

6. The barrier fencing arrangement of claim 1 , wherein the fence panels are formed at least partially from at least one of the following: a mesh material, a fencing material, an expanded metal material, metal, a plate material, a plurality of posts, a grated surface, a framed section or any combination thereof.

7. The barrier fencing arrangement of claim 1 , wherein the at least one access portion is at least one of the following: a doorway, a port, a permanent opening, an access panel, a removable panel, a swinging panel, a hinged panel, a movable panel or any combination thereof.

8. The barrier fencing arrangement of claim 1 , further comprising a post arrangement attached to a least one of a respective foundation member and a respective extension member.

9. The barrier fencing arrangement of claim 8 , wherein the post arrangement comprises a plurality of posts directly or indirectly attached to at least a portion of the foundation member.

10. The barrier fencing arrangement of claim 8 , wherein the post arrangement comprises at least one sleeve member attached to at least one post and positionable at least partially over the extension member.

11. The barrier fencing arrangement of claim 8 , wherein the post arrangement comprises:

a plurality of posts; and

at least one sleeve member slidable at least partially over a respective extension member;

wherein at least one of the plurality of posts is directly or indirectly attached to at least one sleeve member.

12. The barrier fencing arrangement of claim 1 , wherein the at least one fin extends radially from the body of a respective foundation member and includes at least one beveled edge on a bottom portion thereof.

13. A barrier fencing arrangement for blocking both above ground and underground passage, comprising:

a plurality of foundation members positioned at least partially below a ground surface, each of the foundation members having a body with a top portion and at least one fin extending from the body; and

a fence arrangement, comprising a plurality of adjacently positioned fence panels disposed on the plurality of foundation members, wherein the fence panels extend between adjacent foundation members to block passage above the ground surface, wherein at least one doorway configured to permit access through the fence arrangement is defined within at least one said fence panel,

wherein the plurality of foundation members is arranged such that at least one fin of each foundation member is coplanar with at least one fin of each adjacent said foundation member,

wherein each fin is sized to extend at least a distance greater than the width of the at least one doorway and extends to substantially meet a coplanar said at least one fin of an adjacent foundation member such that the coplanar fins of adjacent foundation members substantially span the distance between the adjacent foundation members to block passage below the ground surface beneath each fence panel, and

wherein one of the fins extending from a foundation member associated with a fence panel with a doorway disposed therein extends, toward a coplanar fin of an adjacent said foundation member, underneath the doorway.

14. The barrier fencing arrangement of claim 13 , wherein the fence arrangement comprises:

at least one post having an inner area; and

a fence panel directly or indirectly attached to the at least one post;

wherein the barrier fencing arrangement further comprises at least one coupling extension extending from the top portion of each of the foundation members and positionable at least partially within the inner area of the post.
