Setting up the waste factors as project values allows you to refine waste factors as you use them. Suppose that 5 percent of the cement you pour always becomes wasted material. To calculate the quantity plus waste, you need to increase the quantity by 5 percent. To do this, ply the quantity formula by 105 percent (expressed as 1.05).
Waste factors are usually listed by a percentage of the actual quantity of material left in place. That is, if the actual quantity of concrete required is 100 m3 and the waste factor is 5%, the amount of concrete to be procured should be 105 m3.
construction sites. This wastage quantity will then be compared against the 5% material wastage allowance included within the tendering and estimating process. To achieve this aim, a deductive approach will be undertaken to test the hypothesis that actual material usage on site is greater than theoretical material usage + 5% wastage allowance.
