Question

4. A sustainable construction practice is the balancing of cut (soil to be removed) and fill (soil to be added) for any particular infrastructure site. Unfortunately, any remaining soil that needs to be removed/added to the site will cost an expense per volume. One particular site has a fill and cut of 1,188 and 527 cubic meters, respectively, which must be balanced to determine the remaining demand (i.e. determine the remainder from difference between fill and cut). The truck driver and loader get paid $15/hr., and their hauling capacity is 1,296 cubic feet per trip. The round trip takes 30 minutes, and they work from 7 am- 3:30 pm with a half hour break at noon. The city limit prevents them from having one round trip over 60 yd3, and a daily haul maximum of 1,050 yd. If each limit is exceed the company must pay the employee an additional $10/hr. for the entire day of the haul. How much expense would it cost the company to pay the employees to balance the site? MUST SHOW ENGINEERING METHOD BELOW. What is your calculated answer most closely to? a. $250.00 b. $276.34 IS270.00] c. $200.99 d. $239.58 Find: Given:
