About the CEPCI

Since 1963, the chemical process industries (CPI) have used Chemical Engineering‘s Plant Cost Index (CEPCI) to adjust process plant construction costs from one period to another. Today, however, they have the ability to retrieve CEPCI data more promptly and on demand than the old method of searching for old copies of the magazine or waiting for the next one to arrive with new data.

Platinum Level membership to ChemEngOnline.com provides online access to the entire CEPCI database, including annual (1947 to present) and monthly (1970 to present) data archives. It is by far the most efficient, expedient and convenient way of accessing CEPCI data – whether old or new.
