You have been hired as a project Engineer for a development company in Namugongo to build 610 housing units. Since the original ground is low, you need fill material to raise the ground level. Your estimated fill requirements are 700,000m3 with a void ratio of 0.46. the insitu material at the borrow pit has a void ratio of 0.39 where as the material dumped in trucks has a void ration of 0.71. How many trucks will you need, if each truck carries 10m3 ? i will need all the work outs in full and well explained
