igid direct comparisons are obviously impossible. No two plants in our experience in the chemical industry are exactly alike. Improvements on new processes occur so rapidly that plants of similar procesn and same stream-day capacity are different enough to make direct comparisons difficult. Other variables as site conditions, severity of weather during construction, strikes, changing tariff structure, and political climate contribute to the problem. Direct comparisons are also frustrating because of too few samples in various countries of plants similar with respect to process and capacity. However, taken in context with the use of some s i m p l i ing assumptions, comparisons can be made accurate enough for most fixed capital cost forecasts.

plant units each consisting of material, labor, contractors expense, and profit. Apparently, there exists a ‘pasonably good correlation of similar plant component costs among the various countries. Since the plants selected were not identical, viyiations exist among the sample in the quantity and, therefore, in costs of such utilities as steam, refrigeratioi, compressed air, and water. Extreme variations w uld be expected to affect the relative percentage of tot$ plant

EDITOR’S NOTE

A group of plants in the D category, recently built abroad of similar process and with a range of factorable capacities, was selected for study (Table 111). A breakdown of component costs by percentages of total cost was made for each of the plants in the countries indicated in Table I. The breakdown is by functional

cost of the affected component. However, tde total value of combined utilities for each plant was not sufficient to distort unreasonably, the relaqionship among comparable cost components. In the case of the Canadian plant, the absence of site development, steam

Although designed for similar product mixes, the process plants included in the study were of various physical capacities. Most were constructed as battery limit additions to existing plants. The rest were grass 'roots, requiring roads, railroad sidings, office, shop and warehouse buildings. For comparison purposes, only battery limits installed costs for these projects were considefed in developing data shown in Table 11. That is, only installed cost for process equipment, their appurtenances and applicable engineering were included. No building costs were included. Table I1 shows the plant capacity ratios and the installed cost ratios, all referred to U. S. costs as reference. Costs were first transfortned to a common capacity base by assuming that they varied as the 0.6 power of the ratios of capacities to tbe U. S. reference. The installed cost ratios are therefork referred to a uniform base of similar process and capbcity in the countries shown. A colhparison of this table with Table V of Part 3 in the J$ly I&EC, page 38, shows close agreement of the total relative cost ratios in the same countries. The only ratio which does not check closely is that for Brazil &here a value of 1.05 was evolved in Part 3 compared with 0.96 experienced for an actual plant. There is reasod to believe that the ratio should be nearer the higher figure. The plant's proximity to industrialized areas wdere raw materials such as steel, pipe, and wiring, were readily available and exceptionally good lump-sum construction contracts could well have contributed to

lowering the cost below average. During the construction period, the wide fluctuation of the value of the Brazilian Cruzero relative to the U. S. dollar further tended to lower the plant cost on a dollar basis. Pmiecl Time

Reference was made in previous parts to the duration time for construction as a factor in the productivity equation. Table I11 records total project duration of a number of completed plants here and abroad. Project duration is defined as the total continuous time to engineer, construct and place into operation the process plant. Plants were grouped into installed cost and project type categories as defined in the table. Total elapsed calendar time is significantly greater abroad than on the North American continent for plants of less than $1 million. There is closer agreement in calendar

To enable comparisons of process plant costs, buildiiigs were omitted from the data in Table 11. Requirements for housing varied widely in size, configuration, and construction materials in the plants studied. Experiencc in building costs abroad is recorded in Table IV, on a square foot basis. Twelve feet average ceiling heights for office buildings and laboratories; 16 feet for Tvarchouse: utilities, buildings and chemicals rnanufacturc are assumed. Cost ranges are highest in U. S., Canada, and England; somewhat lower in Australia and India; and lowest in Mexico and Brazil. .4vailahility of indigenous materials generally determines the type o l construction used. U. S., Canada, and England favor steel frame and steel, abestos, or curtain wall sidings. Brick sidings are used frequently in England. Use of concrete, reinforced and prestressed structures is prcvalent in Mexico, Brazil, and India. Building specifications and unit costs are showm in Table V for representative structures defined in colurnn I, for some countries abroad. Buildings varied i n sizc from approximately 6000 to 30,000 square feet total area. Unit installed costs cover complete buildings including lighting, necessary plumbing, heating and ventilation, and engineering costs only.

Import Duties

An important component in the cost of the plant tiuilt abroad is the duty on machinery, equipment, and material which may have to be imported for the process plant. ATever entirely predictable, changing bvorld trade conditions and preferential treatment adds to thc difficulty of forecasting the cost of customs imposts. Although many countries attempt to list duties for specific items, interpretation of the listings with regard to applicability is sometimes quite hopeless. Many dutiable items are subject to negotiation bet\veen thc importer and custom officials. The Bureau of International Programs of' thc U. S. Department of Commerce is an excellent starting source of information regarding foreign import tariff systems. Duties plus ocean freight aggregating up to 30y0 of thc value of all process equipment has been experienced. Duty rate varies generalll- with the availability of thc specific equipment in the country of import. Items not manufactured may enter free in many cases. 'The duty rises rapidly on items manufactured in competition with the exporting country. Basis for duties are weight and/or valuation. The former basis is termed a specific duty and is applied on the gross, legal, or net weight. Sometimes it is applicd on the unit of capacity in liquid shipments. Duties are also applied on the C.I.F. (cost, insurancc: and

The foregoing series represents some of an American chemical manufacturer’s construction experience abroad. The going gets tougher as world-wide industry settles down to the long competitive challenge ahead. The geometric increase in technological know-how abroad tends to decrease the gap in comparative costs. As in the U. S., labor rates will tend to rise with improving productivity and living standards. Taxes and tariff differentials place real limitations on profit margins on exports and the trend toward increased building abroad is bound to continue. Actually, the trend is in both directions. There is already much foreign capital invested in U. S. industry and more coming. Freer world trade is apparent in the growth of the European Economic Community, the Latin American Free Trade Association, the British Commonwealth System, and the “favored nation principle.” The net effect of the impact of these changes would appear to tend towards an equalization of world construction costs. This is hardly likely since the many factors which determine installed costs rule out absolute equalization. Just as there are still differences in construction costs among various sections in the U. S.after many years of industrial and technological growth, so are there apt to be differences in cost among the countries of the world. There is much room for productivity improvement in the U. S.through the advanced technological techniques of automation and optimization. Constant acceptance of the challenge of competition should assure the maintenance of a competitive world position in plant construction and operation. This series covered largely the factors involved in constructing chemical process plants abroad and touched only lightly on others such as, political and economic factors. The May 18, 1962, issue of Business International carried a table of 92 “Factors in Choosing a Foreign Manufacturing Site.” These were broken down in groups under the following headings : Economic, Political, Government, Geographic, Labor, Tax, Capital Sources and Business factors. The table is an excellent check list for those who contemplate building new process facilities abroad. On the basis of correlated information, the West German median average hourly earnings for chemical workers shown in Table I, page 41, May I&EC, should now be 0.72. The median figure should be 0.68.
