the chemical estimator, 1956 was highlighted by the presentation by the AMERICAN CHEMICAL SOCIETY and the American Institute of Chemical Engineers of five symposia concerned with economic phases of the chemical business, and by the formation of two groups concerned with engineering estimationthe American Association of Cost Engineers and an Engineering Economy Division of the American Society for Engineering Education. A summary of a February ACS Delaware Valley Regional meeting on diversification ( 7 M )indicated the value of the session (77J,SK, 9M, 72M, 20M) to those attending. A regional ACS meeting in Seattle, Wash., in June again presented some interesting subjects (25A, 37F, 29M), but only one available reprint (25A)and one derivative publication in an AIChE journal (30M). Unfortunately, neither of the symposia was published, or is even, in general, available from the authors as reprints. A book based on a Philadelphia symposium in April (75C,230, 270, 300, 18E, 79J, 7 7 M ) and several scattered articles based on a Los Angeles symposium in February (240,360, 4E) 72E, 33E, 76J, 25J) resulted from the first two AIChE symposia. The third symposium (New York, October) will probably be published during the year (ZC, 260, 22E, 3 2 M , 35M). The Los Angeles symposium benefited by a somewhat narrower subject range than was covered by the other two, “Economic Justification of Process Industry Proj-
936
ects.” Each of the three had a detailed presentation of capital cost estimating (230, 260, 3 6 0 ) ) a subject that should now be sufficiently covered for some time. A paper at each session (78E, 22E, 33E) discussed the newer techniques for profitability estimation which consider the time value of money. An independent society, the American Association of Cost Engineers, was formed (7OM), with over 200 members reported by October 1956. Discussions presented at the first technical session have been published (75B,770); further information can be obtained from John T. Husted, Secretary, P.O. Box 1411, Trona, Calif. While the formation of such a group outside the established scientific societies may seem unfortunate, the group has expressed willingness to cooperate with others. Plans have been made for a first annual meeting in June. For some years the American Society for Engineering Education has had an Engineering Economy Committee (78M), which during 1956 was converted to a permanent division of the society. Its publication has continued to contain stimulating discussions (ZOC, 380, IE, 77E) S J , 5L, 24L). A Symposium on Decision-Making Processes (QL,75L,28L) at the ASEE 1956 meeting indicates concentration on the development of proper techniques and criteria for engineering estimation. The previous annual review (34M) missed two outstanding presentations of interest to cost estimators. In June 1954, a full week of summer school was
INDUSTRIAL AND ENGINEERING CHEMISTRY
held by this Engineering Economy Committee; the proceedings were published (77L), but are now out of print. These 166 pages (mimeographed) contain more stimulating thoughts per page. for this estimator, than anything published subsequently. They discuss the relation of company capital budgeting to estimation (7L), the contribution of national economic studies (27L), the role played by accounting for both the benefit and detriment of engineering economy studies (79L, 26L), and the impingement of operations research techniques on engineering economy (8L. 76L, 77L, 2OL). Reprinting of these proceedings is a possibility. Among the advanced study courses presented by the Charleston, W. Va.. section of the AIChE (27M) was an admirable series on cost estimation in the fall of 1955. Although unpublished and unavailable except in outline form (30, 80, 250, 370, 320, 74E),the presentations reflect the devotion to professional development which must have inspired those connected with this and associated courses. Worth special note is the presentation of “Capital Cost Estimating” by Bauman (30)which, combined with his comprehensive analysis of utility and offsite facilities published last year, would make a worthy permanent volume by themselves. T h e estimating specialty, like many others, is subject to the danger of oversimplification. Surely a bad cost estimate can be as bad as or worse than none
at all, because the strength of an apparently scientific approach is placed behind intuition. Let me cite three instances of oversimplification, two from the pages of this magazine, with the intent not of embarrassing the authors but indicating a few of the dangers to willing authors of working in specialized fields. A brief book on pilot plant practice ( 2 2 0 ) provides no data on pilot plant erection costs but describes a general cost estimating technique which is inadequate. For example, equipment costs published 8 to 10 years ago are mentioned without reference to equipment cost indexes which must be used to correct for inflation since that time. Freight is not considered in ingredient costing. Two items (apparently based on one source) (20, 3 4 0 ) similarly oversimplify the difficult task of cost estimation. T o one who has encountered projects having working capital over 100% of fixed capital, it is distressing to see the “approximate percentage of total cost” for working capital assigned arbitrarily as 10 to 15%. Surely no one would in practice try to estimate costs without some knowledge of the literature, as reflected, for instance, in this and previous annual reviews. However, this article states, “the estimate of equipment costs is a more complex problem. Often this is a piece by piece problem. Inadequate as this method may seem, it is sometimes the only means at the disposal of the estimator.” No literature whatever is cited. Oversimplification also extends to titles. These can be blamed more on the magazine than on the author; one article ( 7 0 ) entitled “How to Estimate Equ5pment Costs” is simply a nomograph for convenient use of the well known sixtenths factor.
Equipment Section A of the bibliography covers processing equipment; Section B covers auxiliary and offsite facilities such as piping, blowers, instruments, utilities, and buildings. The subject of each article is indicated after the reference and the equipment items are indexed alphabetically in the subject index. Publications during the year added little in the way of general correlations of various types of equipment in a single article; Zimmerman and Lavine in a book on laboratory equipment (37A) and an article (38A) presented the broadest range of data. The “Cost-imating” series by Nelson is also a major contribution (27A-23A, 25B-36B, 77C-79C, 2 9 0 , 40F, 8 6 73G, 9H- 7 7H). An unusual item included for general interest is the correlation by Hadley
(78B) of the cost of U.S. and foreign automobilei “after the manner of Williams et d.”
Manufacturing Cost Section C of the bibliography covers articles dealing chiefly with items to be estimated in the manufacturing cost schedule. As usual, a number of informative articles appeared on the subject of depreciation, listed in the subject index. I n particular, articles by Clark (9C)and Dean (70C) propose new depreciation methods which, if allowed by the Government, would give the manufacturer greater leeway in choice of depreciation allowance. A carefully reasoned article by Norton (2OC) indicates how the profitability of a venture may depend on the choice of a depreciation method under the 1954 tax law. Spacek (25C) states that inadequate depreciation allowances during inflation act to hide a company’s real earnings. Considerable attention was also paid to fringe benefit costs (6C, 7C, 77C, 76C) and maintenance (ZC, 3C, 72C, 22C). Typical royalty fees were summarized (5C). The make-us.-buy problem on ingredients was investigated (74C). Lawrence (75C) tackled the knotty problem of overhead allocation.
Estimating Techniques Included in Section D are several techniques and discussions published before 1956 but considered of sufficient interest to present, as they were not included in previous annual reviews. Ackoff ( 7 0 ) approaches the question of bid preparation in terms of balancing the cost of making an error in the bid against the cost of making further studies before bidding. I n a round-table discussion ( 5 0 ) one company reported the use of projections of inflation indexes on equipment costs, so that fixed capital will not be underestimated because of inflation between the times of estimation and construction. A new “Industrial Engineering Handbook” edited by H. B. Maynard contains sections on economic lot size determination (780),estimating procedures ( 3 5 0 ) , and replacement of machinery and equipment (25E). Intracompany pricing has been accorded considerable attention during the year (790, 270,280). Tielrooy ( 3 6 0 ) ,in an article chiefly on capital cost estimating, introduces a new concept wherein certain manufacturing costs are related to fixed investment. No supporting data are presented.
Profitability This review has not previously covered techniques concerned exclusively with
replacement problems; Section E endeavors to do so, along with the more familiar concepts of profitability determination on new investments. In general, a piece of equipment is purchased as more than a mere replacement of its predecessor, but many investments do not involve expansion or new products, Specialized techniques have been developed for both determining whether the time for replacement has come and comparing available replacement alternatives. Industries other than the chemical industry seem to be particularly concerned with such replacement decisions; the Machinery and Allied Products Institute (MAPI) has developed an entire technique of its own (29E) with a specialized terminology and standardized assumptions. Orensteen’s article (20E) is recommended as a description of the MAPI technique and its assumptions without their specialized terminology. The institute is now developing a broader system which will allow more choice of assumptions. Two case studies ( B E , 35E) attempt to clarify the MAPI method. Other techniques for replacement evaluation are those of capitalized cost (77E, 12E), capitalized present value of costs (ZE, 3 E ) , and payout time, including minimum return rate (24E). Turning to the profitability of investments that are not necessarily replacement, return on original investment is described again (73E). One cursory analysis of investment decisions indicates a lack of complete knowledge of the relevant factors t o be considered when new machinery is purchased (37E). Gordon ( 9 E ) compares both payout time and return on average investment to what he calls the true measure of profitability, the interest rate returned to the investor by the investment. A basic source on this latter measure is cited ( 6 E ) . Interest rate of return on investment is recommended in other references (4E, 5E, 78E, 27E, 23E, 33E, 7 4 J ) . Artidles critical of the technique are also presented (22E, 30E, 34E, 25L). Kiser ( 7 4 J ) reports on a survey of 15 oil companies, all of which use payout time; three also study interest rate of return, the method he recommends. For the first time, articles review and compare various methods for expressing profitability (IOE, 74E, 18E, 79E,33E, 34E). Although none are complete and most express some bias, thorough review will improve one’s grasp of the assumptions, advantages, and disadvantages of each method. An article in French (32E) indicates that comparison of profitability techniques is becoming a worldwide sport. Others recommend extension of return on investment concepts to products ( 8 E ) , to departments (75E), VOL. 49, NO. 6

for inventory analysis (75M), and for analysis of stockholder return (76E).
Chemical Product Data Section F covers cost data on products as various as potato flakes (23F) and nitrogen-15 (36F). Where the subject index indicates data on product “manufacture,” both investment and operating costs are estimated in the reference. Most cost data are still published on major chemical products of long standing, but some data appeared this year on polyurethane ( Z F ) , titanium (78F),detergents from sugar (79F),polyethylene (38F), and radiochemical plants (55F). T h e cost series by Hardy (25F-3OF) has contained some previously unavailable estimates on specialty chemicals, particularly insecticides. Lack of source data and the author’s statements in associated correspondence (23, 2 6 F ) point up the general advisability of including statistical confidence limits with cost estimates. A similar series on basic or intermediate chemical products could be of even broader interest. Potential prospectors are referred to gold processing data (32P). Still, nothing can surpass the fascination of the data on nitrogen-15 (3GF), wherein is proposed a plant to make 50 pounds per day at an investment of only $38,600,000, resulting in a product cost of just over $1000 per pound.
Petroleum Refining The 26 references gathered in Section G were collected purely as a by-product of our study of this cost literature for other purposes. The author would be interested in hearing from anyone interested in gathering and discussing cost data in this field for 1957 and future vears.
Inflation and Cost Indexes Beyond the usual extension of cost indexes for labor, equipment, and construction, Section H includes several interesting discussions of the effects of inflation. The decreasing value of various currencies is expressed as an interest rate ( 6 H ) . Escalation clauses in purchase contracts are considered as an inflationary factor ( 2 H ) . Inflation is said to distort financial statements and profitability calculations (25C, 3H,7H). Replacement studies are extended to allow choice by the capitalized cost technique, including allowance for a constant inflation rate (8H).
Capital Budgeting
For any implemented capital investment decision, cash must be found, and
938
it is obtained at some cost. In Section J are covered determination of the cost of capital, sources of capital, and procedures of capital budgeting before and after the investment decision. While these may not be considered to be within the normal province of the chemical cost estimator, they are a fascinating part of the investment problem. For what does a percentage return on investment indicate, unless you know the cost of capital with which that percentage should be compared? For a succinct discussion of this problem the reader is referred to Soule ( 2 3 J ) . The “cost of capital” is well defined by Small (27J). Chemical Week, in discussing sources of capital, came up with conflicting titles: “Chemical Companies Reduce Their Debt” ( 3 J ) , and “Loans at Popularity Peak” (5J).
processes themselves have been discussed (9L. 75L.28L). In the latter. the incremental approach, highly recommended elsewhere (250, 7J,77J,77M), is criticized as taking the short-range view which may interfere with long-range company plans. The more limited goals of engineering economy have been historically reviewed (7OL)and criticized (9L, 72L, 25L). Other articles have shown the effect on engineering economy studies of changes in the business cycle (5L), proper consideration of accounting data (79L.26L), consideration of salvage and other residual values (22L), consideration of national economics (27L),and their applicability to valuation of obsolescent facilities (73L). Some possible reasons have been presented for the chemical industry’s lack of use of engineering economics (24L).
Research Evaluation
It has been said, and denied with almost equal vehemence, that research projects can be judged by cost and profitability estimation techniques similar to those used just before plant construction. Section K covers 11 discussions of this and related topics. While some companies use formulas and are willing to share them (7R, 70K), other experts maintain that proposed new products with great long run potential, but with costly and time-consuming preliminaries, may be eliminated by such a calculation, as they cannot compete with quick projects of fairly good profitability (77.E)5 K ) . The cost of erection of a pilot plant can be compared with its benefits (4K,7 K ) . Other methods of research budgeting and evaluation of research results are proposed (ZK, 6K, 9K).
Engineering Economy and Operations Research Section L covers other techniques of great use to cost estimators, which were given but brief mention in last year’s review. Many of the presentations covered appeared before 1956; your author can only plead ignorance, as of a year ago, of some of the thought-provoking techniques described in the citations here. The organization (4L), applications (7L), and some of the techniques (ZL, 27L) of operations research have been presented. Application studies on bidding strategy (GL), refinery scheduling (74L,23L),and capital budgeting (3L) have been described. Engineering estimators have been criticized for the narrowness of their value criteria in comparison with those sometimes developed by operations research (8L, 76L, 77L, 2OL). The value criteria and decision
INDUSTRIAL AND ENGINEERING CHEMISTRY
Miscellaneous Section M, Miscellaneous, is included to cover the close association of engineering estimation studies with such fields as product development (79M), market research (3GM),inventory anatysis ( 7 5 M ) , accounting (8M,73M.77M, 37M),plant location (74h1,3 8 M ) , etc., and the converse overlapping of these fields into techno-economics. A survey has been published of the inclusion of engineering economic studies in curricula at 125 engineering schools ( 7 M ) . Bolin (3M) has surveyed the scope and areas of interest of estimates requested from the consulting organization with which he is affiliated. The British book on “Chemical Engineering Practice” edited by H. W. Cremer includes a review of estimation methods (740) and a review of British practices in accounting, costing, and budgetary control ( 4 M ) . Also of assistance to those who may invest in Great Britain is the suggestion of Warner (33M)that American equipment costs are best converted to British terms by a factor of $5 per pound sterling. One essential volume on engineering materials ( 2 2 M ) devotes a paragraph in its preface to costs, including the following: “Cost is an element common to all design . . . The engineer is necessarily cost minded and as a basic first step must consider the over-all materials cost of his product.” Unfortunately, this is the volume’s only reference to costs. This leads to a closing comment. There may seem to be listed here a great many publications of interest to the cost estimator, but many more articles each year are reviewed which should have contained some cost information but do not. One would think that major articles and texts on equipment and chemical
processes would consider some cost information a necessity, but such is not the case. Certainly anyone can bring to mind editions of major texts in the chemical field within the past year which have not contained even enough information to be indexed here. Let us hope the major strides made in the past few years toward inclusion of cost information will continue by converting a major author or two to this principle every year, even
