1. Investment Cost Estimation
The costs included in the investment cost estimate are grouped
into three categories as
follows:
Inside Battery Limits (ISBL) costs
Outside Battery Limits (OSBL) costs
Other Project Costs
The estimated cost of ISBL and OSBL facilities by major process
unit is presented in
Table 3.The estimated total cost of the utilities and supporting
systems project is
presented in Table 4.This has improved the accuracy of the
capital cost estimates to
30%.
The cost estimate initially was developed in U.S. dollars based
on material and labor
costs thatapplied during 2013. The resulting cost estimate needs
to be adjusted to reflect
costs that are expected to apply during the Projects procurement
and construction period.
