A consulting engineering firm is preparing a preliminary cost estimate for a 40-MW advanced combined cycle natural gas-fired power plant. The firm, which completed a similar project in 2012 with a total cost (construction and equipment) of $809.2 million, wants to use a construction cost index to update the construction cost. If the construction cost was assumed to be 25% of the total cost and the index value in 2012 was 8570, estimate the cost of construction for a similar-size plant in 2017 when the index is 9324.
