Step-by-step solved example
Excavate 1000 BCY, swell = 25%, shrink to fill = 10%. LCY hauled? CCY of fill from this material?
1. Loose
LCY = 1000×1.25 = 1250 LCY.
2. Compacted
CCY = 1000×(1−0.10) = 900 CCY.
Answer: 1250 LCY hauled, 900 CCY in place
Excavate 1000 BCY, swell = 25%, shrink to fill = 10%. LCY hauled? CCY of fill from this material?
1. Loose
LCY = 1000×1.25 = 1250 LCY.
2. Compacted
CCY = 1000×(1−0.10) = 900 CCY.
Answer: 1250 LCY hauled, 900 CCY in place
1.Swell of 20% means 1 BCY becomes
2.Shrink 15%: 1 BCY →
3.Truck capacity is usually quoted in
4.To fill 800 CCY with 10% shrink, BCY needed =
5.Load factor (sometimes) is BCY/LCY =
6.Rock often has
7.Mixing 30% swell with 10% shrink as 40% is
8.1000 LCY with 25% swell came from
9.Unit weight is highest typically in
10.Pay quantity for excavation is often
