Keep this bid so it is still here when the customer calls back. Every number on this form is saved together, under a name you choose, along with the figure it gave you, and restoring one puts the whole job back exactly as you priced it. Mark each one won or lost when you hear — the ones you have not heard back on stay listed as waiting, with how long they have been out. Once a few have come back, this panel says how long yours actually take, and how many are still out past that. Once enough of them have been decided, it also says whether the bids you save here have been landing differently lately than they used to.

CONCRETE YARDAGE
Concrete is sold by the cubic yard, not by the square foot. A 20×40 driveway at 4 inches and the same pad at 6 inches for an RV look identical on a lot sketch and differ by half the material on the ticket. Thickness is the number a “$8 a square foot” quote drops.
Cubic yards = length (ft) × width (ft) × thickness (in) ÷ 12 ÷ 27. One cubic yard is 27 cubic feet. Add waste for over-excavate and spillage — 5–10% is a common starting range, not a rule — then expect the plant to bill the next quarter yard. That rounded-up ticket is what you pay, even if the slab only needed 9.88 yards on paper.
At 4 inches: 20 × 40 × 4 ÷ 12 ÷ 27 = 9.88 yards before waste. With 8% waste that is 10.67 yards, billed as 10.75 yards.
At 6 inches: the same driveway is 14.81 yards before waste. Same forms, same square footage, 50% more concrete. If you quoted the 4-inch square-foot price on a 6-inch spec, the extra yards come out of your pocket.

A 20 by 40 foot driveway at 4 inches is 9.88 cubic yards before waste. With a typical 8% waste factor the plant will usually bill 10.75 yards after rounding up to a quarter yard. The same pad at 6 inches is 14.81 yards before waste.
Cubic yards = length in feet × width in feet × thickness in inches ÷ 12 ÷ 27. One cubic yard is 27 cubic feet. Thickness is the term a square-foot rule of thumb drops, and it is the one that changes the ticket.
Concrete is sold by the cubic yard. Two driveways of the same area that differ by two inches of thickness differ by 50% in material. Forms are priced by linear feet of edge, stamped finish takes more labor than broom, and many plants add a short-load fee under about five yards.
