There are natural working units that lend great simplicity to
calculations of cost──such, for example, as a floor panel in a
building, a column, a bridge panel, a pier of masonry, etc.
Another unit of measurement is often obtained through the percentage
of a total or of another unit, such as the amount of sand in a yard
of concrete. Knowing the mix, a percentage of the total yardage of
concrete will be the amount of sand that has been moved.
Care should be taken properly to subdivide the units of measurement.
The ordinary unit of concrete work is the cubic yard or the cubic foot.
The mistake is frequently made, of estimating the cost of forms and of
reinforcement only in terms of the cubic yards of concrete. The cost of
forms should be estimated also by the number of feet, board measure.
Reinforcing steel should be estimated by the pound.
One difficult kind of work to obtain costs on by the regular method, is
the laying of cut stone. A very simple way to obtain this is to paint
on each stone a number, and let the time─keeper get the dimensions of
the stone after it has been cut, before it has been placed in the wall.
Then the stone layer simply records the number of each stone as it is
laid.
A check on the measurement of the quantity of the work done is
frequently obtained by the measurement of the quantity of the work left
undone or of the material remaining in the stock piles.
COST SHOWING
The object of cost keeping is to furnish accurate and early information
to those in authority, both as to where they stand financially on the
work, and what necessities or opportunities there are for improvement
in economy.
In order to accomplish the object of cost keeping, it is necessary that
there be some efficient method of cost showing; and it is essential
that the system of cost showing, in combination with the system of cost
keeping, shall meet the following specifications:
1. It shall be accurate.
2. It shall be simple.
3. It shall be easy to study.
4. It shall be easy to compile.
5. It shall be capable of being compiled in a very short time after
the receipt of the original figures.
