Chemical plant cost indexes - Wikipedia

Chemical plant cost indexes are dimensionless numbers employed to updating capital cost required to erect a chemical plant from a past date to a later time, following changes in the value of money due to inflation and deflation. Since, at any given time, the number of chemical plants is insufficient to use in a preliminary or predesign estimate, cost indexes are handy for a series of

"Marshall and Swift Equipment Cost Index

Marshall & Swift Equipment Cost Index was created to make comparisons between two former quarters or years. Index comparisons are developed by dividing the index for the date for which a cost is desired by the index for the date of the known cost and multiplying the resulting factor by the known cost. The Marshall & Swift Equipment Cost Indexes are based on a national average for 47 different
