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.
