A contractor is using a crawler D$7$G dozer w$/$straight blade. The dozer is operating on a loose stockpile material that weighs $70$ pcf in the bank state with a swell percentage of $12\%$ from bank to loose state. The dozer pushing distance is of $150ft$ over an uphill of $5\%$ grade. The operator is of average skill and the job will be performed in good conditions. The operational efficiency is estimated to be of $50-$min hour. The figures below provide information about the dozer. What is the productivity of the dozer in $BCY$ per hour?
