Building #120 was constructed in 1985, the 112 sq. ft. Building 133 was constructed in 1986, and the 324 sq. ft. Building #113 was constructed in 1988. The guard buildings are all small rectangular buildings. Building #100 is concrete block with fixed metal sash, multi-pane windows, and a flat roof. Building #120 is of concrete and has large single paned, metal sash, fixed windows. It has an extending roof with booths for badge checks of automobiles. Building #133 and #113 are metal with fixed single paned windows. Building #133 has a sliding metal and glass door for a badge check for automobiles. This group of guard buildings checked traffic entering from the west side of the plant. Building #100 (1966) at Gate 8 controlled access to the original site. As security tightened in the 1980s, three more guard facilities were added: Building #120 (1985) at the outer entrance to the buffer zone; Building #133 (1986) in the west parking lot for Building #130; Building #113 (1988) at the west end of Central Avenue at the parking lot for Buildings #111, #112, and #115.
