MOTION STUDY
The inroads of concrete, both plain and reinforced, how-
ever, have changed conditions, and the bricklayer himself
is, more than any other one factor, the cause of many cases
of substitutions of concrete for brick.
The architecture of any country is determined by the
relative cost of building materials in place, and the history
of the world shows that the way to get the most of any one
thing used is to make it the lowest in price.
The one thing that will reduce the price of brickwork
more than any other is to reduce the cost of the motions.
After the laws underlying motion study have all been
applied, the cost of motions can still be reduced from one-
third to one-half by separating the motions of the brick-
layer into at least two classes, such as, for example:
i. Those that require skill.
2. Those that require nothing but strength, endurance,
and speed.
Those that require skill should be divided into several
classes, according to the amount of skill required; those
that chiefly require skill should be handled by mechanics,
and those that chiefly require strength, endurance, and
speed should be handled by specially trained laborers.
This is the only way to enable brickwork to compete with
concrete, when all of the architects, engineers, owners,
and contractors shall have learned the full possibilities of
concrete.
It will be urged that such division of the work of
bricklaying will lower the genera] skill of the bricklayers
