CHAPTER IX
CONSTRUCTION PRODUCTIVITY IN RELATION
TO OTHER INDUSTRIES
The comparative productivity studies of this chapter
have been prepared to evaluate the 1 per cent per year
Increase in construction productivi-ty established by
Chapters IV and V. These Indicate that over-all United
States productivity has been increasing at the rate of 2.5
per cent or more per year. Surprisingly enough, manufacturing,
which we normally consider to be the pacemaker
of productivity, has an annual rate of Increase somewhat
below the United States average at about 2 per cent per
year, while transportation is above average at around 3 per
cent per year. This trend is further illustrated by the
Index of Output per Manhour for Manufacturing which is
increasing at about 2.5 per cent per year.
Each of these productivity curves is plotted for
comparison with the rate of productivity of the Standard
Building in Figures 18, 19, and 20. From these it will be
seen that the rate of Increase in both transportation and
manufacturing appears to be on the rise for the past ten
years approaching a rate of 3 per cent per year while construction
show no Indication of an accelerated pace. The
total United States productivity curve seems also to be
