Problem 4: After the construction of a concrete retaining wall, backfill material from a nearby borrow pit was brought into the excavation behind the wall and compacted to a final void ratio of 0.8. Given that the soil in the borrow pit has void ratio of 1.1, determine the volume of borrow material needed to fully compact backfill, knowing that the total volume of the backfill is 30 m³. Excavation Ground level Compacted backfill Soils from borrow pit (e = 0.8) Concrete (e = 1.1) retaining wall

Issues During Construction

Construction is the combination of art, science, and engineering to build buildings, bridges, structures, roadways, highways. airports, etc. The construction business is a challenging and promising business worldwide with certain risk factors involved. Increasing demand for mankind leads to the growth of several construction companies which specialize in different construction projects. These construction companies initiate their construction process under certain agreements and time durations called the construction contract.
