COATINGS & LININGS
however, a $650,000 below budget
"savings" resulted. Of course the
chief executive officer was delighted until new test equipment
showed the fallacy of the decision.
It was then that the engineer
switched products from a high-
build epoxy to a high-build polyurethane to hold costs down. With
no supporting data the polyurethane was specified at 60 mils,
another 20-mil decrease. Those
tradeoffs were conducted in the
wrong manner. The correct use of
tradeoffs allows lower installation
costs, while maintaining a high-
quality installation. By eliminating
costly specifications that are counterproductive to the coating or
project, many dollars can be
saved. For example, it was noted
that the high-build epoxy was usually cleaner before blasting for
overcoat than after. Its natural surface texture left a perfect natural
anchor pattern. The savings from
labor, sand, and equipment costs
were spent in increased product
milage. The wall was improved in
quality at no extra cost.
By using the best proven production techniques a much higher-
quality job could be possible at a
reduced cost. By knowing production rates the jobs scheduling
could be carefully planned to take
full advantage of the best climatic
conditions. With full knowledge of
product, job layout and design,
equipment, and manpower use
great savings can be realized.
Place Emphasis in Areas That
Produce Greatest Results
Once the tradeoffs are understood competent decisions can be
made to save dollars. It might be
found that the incremental difference contributed by white metal
blast as compared to near white
blast is not worth the extra expenditure of funds for a given product. By analyzing all contributing
factors quality can be maintained
while dollars are cut, or quality can
be improved while costs remain
the same.
Whichever you choose to do
will be determined by the financial
condition of the company or the
present value of money and expected interest rates. By making
solid economic choices products
and projects will perform to expectation. No intelligent professional
would ever ruin a product or
project for lack of $0.15 on the
dollar. Rather, a knowledgeable
individual could find ways to improve the quality of the project
while saving ($0.15) on the dollar.
With all factors known, intelligent
professionals can make sound
competent decisions.
Conclusions
With the use of pretesting
much knowledge can be gained
and many oversights can be eliminated. Job quality results will be
superior. Job costs will be the least
when figured for the long term.
Accountants will have economic
models on which to base their job
cost projections. Engineers will
have adequate job-site knowledge
and product knowledge with
which to plan. Owners will know
what they are buying and at what
per-annum price. Product manufacturers and the scientific community will have large databases
from which to work. The circle of
maximum product performance
can be measured for each area and
exposure. Inspectors can be well
trained. Job scheduling can be improved. Finally, contractors can install the work that meets the owners needs and expectations at the
least possible price.

CATH0DIC PROTECTION
INSTRUMENTS
CPV-4
CPV-2
The CPV-4 voltmeter has an ALL
NEW liquid crystal display that
endures cold temperatures. It can
be stored at levels as cold as
-55°C. This completely modern
voltmeter will give you immediate
readings of structure-to-earth potentials every time. For reliable
economy, the CPV-2 has a gauged
meter for quick field inspection.
Both units are rugged, lightweight
instruments for cathodic protection.

REFERENCE ELECTRODES
Tinker & Rasor's copper-copper
sulfate reference electrodes are
made of the most durable plastics and feature full-view windows for easy liquid level observation. Special grooved ceramic
plugs enable inspection in hard
soil — and all electrodes allow
quick attachment to any length
of cable. A waterproof adapter is
also available for use in tanks.
