I second this question; I’m trying to work out if we should be putting the total volume of concrete expected to be supplied to the project (i.e. 11m3 in this example) as the project quantity, or if it should be the amount used in the final building (i.e. 10m3).
Essentially, does the 10% waste factor increase the amount of concrete above what we include as the input quantity, or does it take a portion out of what we specify as waste?
