Q14. A contractor is excavating the below trench. The contractor is supposed to dig the trench 5ft deep and 3ft wide. The soil was tested to have an approximately swell factor of 112% and a shrinkage factor of 14%. The contractor is placing a 10" water pipe in the trench and then backfilling with the soil that was removed. The dimensions are on center line. Does the contractor have enough soil to backfill the trench, or will he/she have to need more? If more soil are needed, how much does the contractor need to bring in. Answer in LCY.
