The Company has broken the proposed AMI project down into its major components, and made
an AACE determination on each. As a result of that analysis, it was found that a substantial
portion of the project warranted a Class 3 (26.5%) or Class 4 (2.6%) classification.
As a result, when discussing the project as a whole, FortisBC considers it prudent to consider it
as a Class 3 classification. The aggregate contingency estimated for the project (at 6.4%) falls
within the AACE guideline of -20 percent / +30 percent.
