Install and Compact Aggregate Sub-Base

we're gonna be racing the weather uh but yesterday we got patio all excavated out got a couple lifts of our recycled class five in this so uh plan for today is we're gonna get the string lines back up get our pipes set and start screeding out and uh race the rain six inches of the three-quarter clear base material is included in all of our flat rate plate pricing plus one inch of sand but what happens if we need to deepen our base for the pavers and go to eight inches how do you account for that pricing because when you deepen the base you increase the amount of excavation spoils that you have to haul out and also the amount of material that you need to import to offset that excavation here's a formula that i've used in the past that seems to work and it's one dollar per inch per square foot let me explain if we're gonna deepen the base two inches that means every square foot surface area of that patio we can charge two more dollars per square foot if we're gonna deepen the base by three inches that means we can charge an additional three dollars per square foot on top of our regular price and that's a premium price because we've got to modify the base and modify our construction techniques and the important thing is we've got to account for those changes in the project because if we don't account for them now while we're working on the project at the end of the year our financial statements will account for those changes for us by subtracting away from our profits
