NAVFAC P-300 Management of Transportation Equipment

5.2.4 TOA Organization. Individual line items of material and equipment are
identified by stock number: either National Stock Number (NSN) or Navy Item Control
Number (NICN). Stock numbers for Civil Engineer Support Equipment (CESE) are
listed within the Equipment Codes (EC). Other stock numbers are assembled within
functional Assemblies. Assemblies are grouped functionally into either Groups or
Facilities. Groups and Facilities are segregated by major category or material into
Sections, and by purpose into Echelons, within the NCF Tables of Allowance and the
Advanced Base Functional Component (ABFC) System components.
a. The ABFC Component and NCF Tables of Allowance. An ABFC
Component and NCF Tables of Allowance are designed for personnel, material, and
equipment required to perform specific taskings delineated in OPNAVINST 5450.46,
Doctrine and Policy Governing U.S. Naval Mobile Construction Battalions. Components
and TOAs are given names to indicate their functions, and unclassified codes that
consist of letter (alpha) and number (numeric) combinations. For example: A Naval
Mobile Construction Battalion (NMCB) in the NCF Tables of Allowance system is
designated "P-25," and has an ABFC counterpart designated "P-25." The NCFSU
Table of Allowance is designated "P-31," and has an ABFC counterpart "P-31."
b. Echelons. In both contingency and day-to-day operations, an NCF unit
may be required to support, simultaneously, multiple projects and tasks in various
locations. Preplanning for such contingencies and management of resources required
to support these operations are aided by "echeloning" certain TOAs. For example:
The NMCB Table of Allowance is echeloned into an Air Detachment, an Air Echelon,
and a Sea Echelon. This echeloning is based on anticipated prioritization of personnel,
material, and equipment, and the availability of airlift versus sealift support. The
NCFSU Table of Allowance is echeloned to augment and support various special
operations which are beyond the organic capability of the NMCBs.
5.2.5 Allowance Review. The Naval Facilities Engineering Command
(NAVFACENGCOM) and the Civil Engineer Support Office (CESO) will initiate a
complete annual review of each TOA by inviting comments and participation from all
Commands that have an interest in the TOA under review.
5.2.6 Initiating TOA Changes. All changes to TOAs managed by NAVFACENGCOM
will be initiated in accordance with NAVFACINST 4423.1, Modification and
Documentation of Naval Facilities Engineering Command Managed Tables of
Allowance.
a. Format. The NAVSUP Form 1220-2, Allowance Change Request/Report,
or a formal letter are the prescribed documents to request item addition/deletion, or
quantity increase/decrease in all published allowance lists. Submit justification for
each suggested allowance modification.
