Note 1: For construction, equipment combinatations other than those shown could be configured. Information shown below is for cost estimate purposes only.
Note 3: Instead of D9 dozers, D6 dozers may be preferable because of maneuverability. Assuming D9 dozers is conservative.
Note 4: For Types 3 and 4, larger excavators or shovels could be feasible.
Note 5: Crews and productivities based on conversations with contractors, index values in the 2008 equipment library, RS Means cost data, equipment manufacturer's data, and unit price data
