In excavating, how many compacted cubic yards (CCY) are in 1,320 LCY if the shrink factor is 1.54?

To determine the number of compacted cubic yards (CCY) from loose cubic yards (LCY) given a shrink factor, you divide the loose cubic yards by the shrink factor. In this instance, the shrink factor is 1.54.

You begin with 1,320 Lacy and use the formula:

CCY = LCY / shrink factor

Substituting the values gives:

CCY = 1,320 LCY / 1.54 ≈ 857.14

When rounded down or approximated for practical purposes, this leads to approximately 857 CCY. This value is the most accurate calculation when considering the shrink factor's influence on the conversion of loose material to compacted material. Thus, this illustrates how understanding and applying the shrink factor is essential in excavation work to determine the correct quantities needed for projects.
