I painted "FW7" material on stairs stringer, and below can be seen that "Stringer" painting takeoff = 9.60m2 also calculated on "Cast-in-place Stair" painting takeoff = 9.60m2. And the total material takeoff, includes both of them instead on only one.
So we can't use the painting takeoff as-is? I should first deduct 9.60m2 from the Total to be the correct value.
Beside stairs, is there any element that I should be careful of?
