4. ESTIMATING ROAD CONSTRUCTION UNIT COSTS

Road construction superintendents can often estimate the number of meters per hour that their equipment can build road based upon local experience after looking at the topography. The engineer's method is to calculate the number of cubic meters to be excavated using formulas or tables for calculating earthwork quantities as a function of sideslope, road width, cut and fill slope ratios.
