Existing Units: Billeting area is composed of a group of K-span divided into four pads; PAD A, Pad B, Pad C and Pad D.

Each pad have aligned, on their respective East and West laterals, the existing containerized units. Each section (lateral) is composed of four Units. One laundry unit (6 washers/6 dryers), one lavatories unit (16 lavatories), one latrine unit (5 commodes, 1 urinal and 2 Lavatories) and one shower unit (6 shower heads and 2 Lavatories). This pattern is repeated in each Eat and West lateral section of each pad, for a total of 8 section. Total existing containerized units count is 24 units.
