table chemical engineering cost indexes. process equipment cost estimating by ratio and indicators chemical engineering plant cost index cepci and weekly in engineering news the first step is to determine the cost index for our two dates referring to table the cecpi index for 2001 is found to be online chatall costs should be for the present time, or estimated for the proposed construction time. use the chemical engineering plant cost index or another cost index to update equipment costs: last page of each issue of chemical engineering:the cepci inputs also include labor-cost indexes these indexes are also compiled by bls. they track changes in labor rates, for such categories as fabri- cated products and general building contractors. In addition, special labor- cost indexes are included for technical specialties, such as engineers and de- signer-drafters.
Correlating The Chemical Engineering Plant Cost Index With
feb 01, 2014 the chemical engineering plant cost index correlates well with macroeconomic factors. current oil prices and current and past interest rates are the independent predictors. these predictors may also reflect market conditions, inflation and unit labour costs. the correlation is accurate within over the period and over 11.152 cost indexes utep college of engineering. many of the indexes that are frequently used by engineers are updated monthly and published in professional journals like engineering news record and chemical engineering table shows the values for three of the most common indexes for the years thru the general equation for updating costs through the use of a cost index is:. cost index, is a number that indicates the value of a piece of equipment or a plant at a given time, compared to that of the same unit or plant at a reference time. cost indexes are used to perform an estimate of the actual cost of a process unit if the cost of the
The Chemical Engineering Plant Cost Index Chemical
for more than years, chemical process industries professionals engineers, managers, and technicians have used chemical engineerings plant cost index to adjust process plant construction costs from one period to another. this index rather, indexes, as it consists of a composite index and eleven subindexes has received such wide acceptance that it has even been written table the component-indexes are compiled, and with appropriate weighting factors, are added up to make up the equipment index. inde-pendently, three other sub-indexes are compiled, and with appropriate weighting and normalizing, the four sub-indexes add up to the cepci. while table is informative, it is a lot easier to see trends and relative
