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.

A surcharge and sand drain installation is proposed for an airport project to accelerate the consolidation of a thick deposit of fine-grained soil underlying the construction area. The plan is to install sand drains 1.5 ft in diameter at a staggered spacing so that each sand drain will handle a plan area 15 ft in diameter. Laboratory tests indicate that the coefficient of consolidation for horizontal drainage of the soil is 0.5 ft2/day. Computations indicate that the surcharge load will cause an eventual settlement of 12 in. How long a period will be required for 90 percent of this settlement to take place?
