Excellent video. Thank you!

Civil engineer, here.
The 25% increase is a highly local rule of thumb. It depends of local custom and on the type of soil. Some soils shrink and swell more than others.
Consult with your local expert.

Good explanation

[@edgarsolis5011]

So if I build a building pad that is 20x25x2 feet, which has a volume of 40CY taking shrinkage into consideration after compaction. If I add 25% which would bring me to 50CY. Is that a good way to go about calculating how much material I should quote/order to avoid coming up short after compaction?

Nice and easy to understand..

[@oleopathic]

So from dense to least dense condition we have;
CCY > BCY > LCY
Agree ?

Simple and easy understand

[@jamesboutilier471]

Uses too many acronyms making the explanations harder to follow. Instead of overusing LCY, BCY, AND CCY just say banked, loose or compacted.

[@oleopathic]

Agree.
