assembly number relates to the Occupational Field 12 skill required to install it. The groupings are numbered, as shown in table 9-1.

Tailoring Components and Facilities

When you use the ABFC system, remember to tailor it to your specific needs. Know your exact mission and its requirements. Choose the components, the facilities, or the assemblies that best fit or can be tailored to meet your desired goals. Develop modular elements to serve similar functions in various locations. The exact requirements for a specific base cannot be defined, economically designed, nor supported within the general system. However, the base development planner knows the specific location, mission, unit composition, and availability of other assets. The planner can then select from the ABFC system the components or facilities that satisfy these specific requirements. Tailoring is then applied to the preplanned ABFC assets to come up with what is needed.

Tailor components or facilities by either (1) deleting or adding facilities or assemblies and (2) specifying requirements for the Tropical or North Temperate Zone. Assemblies required only in Tropical installations are coded with the letter T in the zone column to the right of the assembly description. Assemblies required only in North Temperate installations are coded with the letter N. Uncoded assemblies are common to both zones.

Use and Application of the Facilities Planning Guide

Although a listing in the P-437 may help you order individual items in general supply, it does NOT replace stock lists of systems commands or bureaus, offices, single managers, or inventory control points. Stock numbers and descriptions can be verified through appropriate stock lists. You are responsible for verifying stock numbers when ordering a component, a facility, or an assembly.

COMPONENT. - Figure 9-2 shows a typical component breakdown of the P-25. A brief header describes the mission and capabilities of the component. The site plan, pertaining to each component, is shown by a NAVFAC drawing number. However, drawings in volume 1, part 1, are indexed by component designation, not drawing numbers. The word NONE appears for components that have no site plans. The facilities required to make the component operative are listed in numerical sequence by DoD category code. The alpha suffix for each facility designator indicates differences between sizes, types, or layouts of facilities with the same functional purpose. Facility capacity is expressed in terms of the units of measure used in the Category Codes Facilities, NAVFAC P-72. The component capacity is figured by multiplying the facility capacity and the quantity. Weight and cube are measured in normal units for export packing.
