(39) In this embodiment of the invention, foundation assembly 22 includes side members 40 and 42, back member 46, front members 44A and 44B and ramp 47, as shown in FIG. 6. Side member 40 extends between and is connected at its ends to front member 44A and back member 46. Side member 42 extends between and is connected at its ends to front member 44B and back member 46. Back member 46 extends between and is connected at its end to side members 40 and 42.

(40) The front of foundation assembly 22 is formed by front members 44A and 44B and ramp 47. One end of front member 44A is connected to an end of side member 40. One end of front member 44B is connected to an end of side member 42. Front members 44A and 44B are longitudinally spaced. Ramp 47 is in that longitudinal gap between front members 44A and 44B and is fixedly attached to those members.

(41) Each of side members 40 and 42, back member 46 and front members 44A and 44B are comprised of angles 48 and 52, as shown in FIG. 7. Angle 48 includes first flange 49 and second flange 50. Angle 52 includes first flange 53 and second flange 54. As shown in FIG. 7, angles 48 and 52 are relatively positioned and connected such that first flange 49 of angle 48 and second flange 54 of angle 52 abut and are connected by welding or other attachment method and second flange 50 of angle 48 and first flange 53 of angle 52 are spaced and parallel, as shown in FIG. 7.

(94) In this embodiment of the invention, bench 26 is along first side wall assembly 32 and A/V communications module 106 is embedded in second side wall assembly 34, so that a person sitting on bench 26 is facing video monitor 109 attached to A/V communications module 106.

(95) Bench 26, video monitor 109, window frame assembly 66 of front wall assembly 30 and window frame assemblies 86A and 86B of first side wall assembly 32 are positioned relative to each other such that a person or persons on bench 26 are readily observable through window frame assemblies 66, 86A and 86B and video monitor 109 is readily observable through window frame assemblies 86A and 86B.

(96) Alternatively, a movable bench or other seating support can be utilized in secure video visitation booth 20 such that the bench or other seating support can be moved within secure video visitation booth 20 as desired.

(97) Door 27 is rotatably attached to door frame assembly 68 and can be locked in the locked position from outside to secure video visitation booth 20.

(98) The secure video visitation booths of some embodiments of this invention may include a built-in or movable table, in addition to a bench. For example, in the embodiment illustrated in FIG. 27, secure video visitation booth 20, includes built in table 27 attached to floor assembly 24 and/or first side wall assembly 32, adjacent to bench 26.

(99) In the secure video visitation booths of other embodiments of this invention, a ventilation fan can be provided in one of the ceiling panels and front, side and back wall assemblies. In the embodiment of FIG. 31, ventilation fan 131 is in side wall assembly 32 of secure video visitation booth 20.

(100) As stated, a plurality of the secure video visitation booths of this invention can be arranged in a room or other building space of a correctional facility. Adjacent booths can be joined together by a plate, such as plate 125 shown in FIG. 29.

(101) In addition, as stated above, some of the embodiments of this invention do not include a foundation assembly or a floor assembly.

(102) For example, as shown in FIGS. 34 and 35, one or more of front wall assembly 30, first side wall assembly 32, second sidewall assembly 34 and back wall assembly 36 may have tube 152 at its lower end (back wall assembly 36 is shown in FIG. 34). Angles 154, with upright leg 156 and horizontal leg 158, may be affixed to tube 152 by welding upright leg 156 to a face of tube 152. Horizontal leg 158 may have spaced holes to receive fasteners for fastening horizontal leg 158 to an existing floor.
