Yоu аre emplоyed аs а cоnstruction engineer on a new municipal recreation center project. The sitework phase includes excavation for a swimming pool and underground mechanical piping. Based on the design drawings, 6,000 bank cubic yards of soil must be excavated. Once the pool structure and utilities are complete, approximately 2,800 compacted cubic yards of material will be required for backfilling and grading. The excess soil will be transported off-site to an approved fill location. The average haul distance is 750 feet, with a 2% uphill grade. Laboratory tests on the soil samples provide the following data: Bank density = 2,600 lb/bcy Loose density = 2,150 lb/lcy Compacted density = 3,700 lb/ccy What is the percent swell for the soil? What is the percent shrinkage for the soil? How many bank cubic yards should be stockpiled to be used for backfill operation? How many loose cubic yards of soil should be hauled away to the disposal site?
