f. Site Survey and Staking. Survey the site and stake the activities before setting up any FP
module subsystems. Once surveyed, the control points for each subsystem will be marked with a stake
and flag (or spray paint on hardstand) IAW the site layout. Within each subsystem, the operators will
stake the location of tents and equipment IAW the FP TM using the control points as reference. Setup
of each FP subsystem should adhere strictly to the marked staking plan.
g. Special Preparation. There are several subsystems in the FP module that require special
preparation considerations. These subsystems are listed below.
(1) Berms. All collapsible 500-gallon and 20,000-gallon fabric fuel tanks will be emplaced
in a berm with raised sides to contain possible fuel leaks or spills.
(2) Culverts. Electrical cables and potable water and graywater hoses should be buried under
roads or pathways to prevent damage. Culvert sections should be used to protect cables and hoses from
being crushed or separated. Where potable water hoses cross over or parallel graywater hoses, the
potable water hoses must be given 24 inches of vertical and horizontal separation to prevent potential
potable water contamination. Either bury the nonpotable hose or use sandbags to raise the potable line
24 inches. The couplings of potable and gray-water hoses must be separated by at least 36 inches to
ensure that graywater leaks do not contaminate potable water. When burying fuel lines, ensure that
culverts can be inspected for signs of leakage and that precautions are taken to prevent spills from
entering surrounding soil.
(3) Hardstands. Several surface areas must be hardened to provide a stable footing for heavy
equipment and high traffic facilities. The containerized latrine, the containerized batch laundry, the
diesel power generators, the 600-cubic-foot refrigerators, and the food service subsystem dining facility
all require hardstand emplacements. The FP TM gives specific information concerning the weight and
size of these facilities and equipment.
(4) Helipad. A helipad is part of the FP site. The primary use of the helipad will be for
medical evacuations. Locate the helipad as close as possible to the FP medical TEMPER. Materials
needed for construction of the helipad, such as
