Calculate the total operation time for this construction activity if the volume of soil to be removed is 8 cu.m. (considered 33% for bulking of materials.) The speed of dumptruck is 30 kph and travel distance (round trip) from the source to disposal area vice-versa is 6 km. The bucket size of excavator is 0.50 cu.m at 0.50 min loading time, tipping time is 4 mins.
