I'm looking for a published source for Process Plant Capacity Cost Factors. I know that at least one reference manual of this type exists as one of our Estimators has produced a page from one that was lost (circa 1970).
Essentially it is a book of Charts by manufacturing plant type with...
Tkhan,
As an Estimator working in the BipPharm, Chemical and Petrochemical areas for one of the largest international E&C companies, I can extend to you my personal opinion.
The true cost of an Estimate is determined by the amount of risk the bidder underwrites (using the Estimate)versus...
Estimating is a complex area. If you are still in a position where you're required to Estimate Plant Construction costs contact me. I'll try to assist.
My recommendation(s) would be dependant on your requirements.
In general there are OOM (conceptual +/-25-30%), Budget (+/-15-20%) and...
Actually there are a variety of systems: Hot Oil, Steam, Hot water,Electrical, etc.
The fluid/steam systems employ a supply line (from the header) to a supply manifold, leads (pre-insulated tubing)to the traced line, tracing (bare) tubing to a max of 80 LF or so and a return (condensate in the...
Percentages vary according to the project requirements and competitive business climate. For example a typical petrochemical facility would be on the order of 18% of the capital cost ( or Total Direct Cost), this would translate into 12% of the bottom line (Direct plus Indirect).
Don't forget...
