Because of the abundance of chemical engineering plants in the U.S Gulf Coast, it is often the standard for plant and equipment cost. Cost of plant construction will differ based on:
- Construction Infrastructure
- Labor costs
- Transportation costs
- Tax Rates
- Exchange Rates
It is common to convert cost of construction to locations other than the U.S. Gulf Coast by applying a location factor in which:Cost of Plant Construction = (Cost of Plant in Gulf Coast) X (Location Factor)
