Choose the lowest size and the required number of crawler hoes to excavate 828864 b-Cyd of sand & gravel in 4 months. A size one Cyd excavator (including the wage's operator) costs $80 /hr. with an increment of $5 per extra 0.5 Cyd. Depth of excavation 12 ft, Swell 25%, and efficiency 65%. Suppose the work is 8hr/day. Estimate the total expected cost.
