Selection of Sustainment Cost Factors
In selecting from possible sustainment cost sources, the most credible factor was assigned to each facility category. General
"credibility" was determined by a priority scheme for groups of cost factor sources.
Sustainment Cost Factor Source Hierarchy
Standard, off-the-shelf, commercially published sources (e.g., Whitestone). These sources are considered most desirable due to ease of
Source 1
access, wide applicability, and lack of bias. Publications cover whole facilities and separate components of facilities, and include
factors from professional associations and certain non-DoD federal, state, or local government agencies.
Source 1 cost factors that are applied to facilities with similar but not identical characteristics (e.g., sewage waste treatment facilities
Source 2
and industrial waste treatment facilities). Source 2 also includes Service-validated cost factors for facilities that have no commercial
counterparts (e.g. missile launch facilities or military ranges).
Cost factors derived from Source-1 factors by multiplying the construction cost factor by the ratio of the sustainment cost factor to the
Source 3
construction cost factor for a similar Source-1 Facilities Analysis Category (e.g. FAC 2115, Aircraft Maintenance Hangar, Depot
derived from FAC 2111, Aircraft Maintenance Hangar).
Distribution of Sustainment Cost Factors
For each cost factor, the cost factor table indicates the source group (1, 2, or 3) that is intended to reflect its relative accuracy
and credibility. In version 5.0 of the pricing guide, 77% of the facility categories (representing 93% of DoD's plant
replacement value) are assigned Source 1 sustainment cost factors.
Revisions to Sustainment Cost Factors
Sustainment cost factors in this version of the Guide have been updated from the previous version. Changes may be due to any
of the following reasons:
Changed commercial cost components (for those cost factors based upon commercial benchmarks, such as the
Whitestone MARS model)
Changed composition of the FAC (i.e., changed mix of constituent facility category codes)
Changed source of data (to a more credible source) or changed methodology for cost calculation
A "ripple effect" where a cost factor for one FAC is directly derived from another changed cost factor
