``The basic hourly rate of pay'' is that part of a laborer's or
mechanic's wages which the Secretary of Labor would have found and
included in wage determinations prior to the 1964 amendments. The
Secretary of Labor is required to continue to make a separate finding of
this portion of the wage. In general, this portion of the wage is the
cash payment made directly to the laborer or mechanic. It does not
include fringe benefits.
