UM = SY
Construction Cost Factor (CCF)
.96/SY, based on data provided from a study conducted by the University of Kansas' School
of Transportation, inflated to FY04 $ using the appropriate OSD published inflation rates. The CCF
represents a split between asphalt (7/8) and concrete (1/8) road surfaces.
Sustainment Cost Factor (SCF)
.53/SY, based upon data provided
by various state DOTs. Data provided
by the various states
was for non-interstate, low volume (compared to a state highway), in line with the average usage of the
Service's assets. Change in source was based upon the fact that DoD's performance should be no worse
that state governments.
