Pricing Excavation and Backfill

Backfill, in construction, is the activity of returning the soil and gravel that are removed during building construction or using them again to toughen and support the foundation of the building or any other structural component.

Question

100%

Do not give wrong answer. I will surely downvote A highway embankment with a volume of 800,000 cy is being constructed by compacting dry gravel borrowed from a nearby site. In its natural state, dry gravel has a density of 1,660 kg/m³ with a swell percentage of 12.5% and a shrinkage factor of 0.85. (a) Calculate the loose density of the gravel in kg/m³. (b) Calculate the load factor. (c) Calculate the compacted density of dry gravel in kg/m' and compact factor." (d) Calculate the volume of the required material in bm.
