Exercise 13

A consulting engineering firm is preparing a preliminary cost estimate for a design/construct project of a brackish groundwater desalting plant. The firm, which completed a similar project in 2003 with a construction cost of $30 million, wants to use the ENR construction cost index to update the cost. If the index value in 2012 was 9290, estimate the cost of construction for a similar-size plant in 2012.
