Marshall and Swift equipment cost index

Table 9-42 presents information on some cost indices for the United States. Engineering News-Record updates its construction-cost index in March, June, September, and December. The Oil and Gas Journal gives the Nelson-Farrar refinery indices in the first issue of each quarter. The Chemical Engineering plant-cost index and Marshall and Swift equipment-cost index are given in each issue of the pubhcation Chemical Engineering. Derivation of the base values is referred to in the respective publications. 

Marshall and Swift Equipment Cost Index [57]. Commonly used for process industry equipment and index numbers presented by industries in Chemical Engineering Magazine on a monthly basis. 

For use with process-equipment estimates and chemical-plant investment estimates, the Marshall and Swift equipment cost indexes and the Chemical Engineering plant cost indexes are recommended. These two cost indexes give very similar results, while the Engineering News-Record construction cost index, relative with time, has increased much more rapidly than the other two because it does not include a productivity improvement factor. Similarly, the Nelson-Farrar refinery construction index has shown a very large increase with time and should be used with caution and only for refinery construction. 

The purchased cost of a 50-gal glass-lined, jacketed reactor (without drive) was 8350 in 1981. Estimate the purchased cost of a similar 300-gal, glass-lined, jacketed reactor (without drive) in 1986. Use the annual average Marshall and Swift equipment-cost index (all industry) to update the purchase cost of the reactor.

All indices in Figure 7.3 show similar inflationary trends with time. The indices most generally accepted in the chemical industry and reported in the back page of every issue of Chemical Engineering are the Marshall and Swift Equipment Cost Index and the Chemical Engineering Plant Cost Index.
