I am framing a house on a concrete slab. There are three bearing walls in the interior which support the second floor joists. The slab is not very flat, using a transit and checking with string lines there is up to a 3/4 inch difference in height at various points along the bearing walls. To be sure that the walls are uniform throughout we have been running string lines from outside walls parallel to the interior bearing walls and cutting each stud according to the string. This system is working but it is very time consuming. We will be starting a very similar house on the next lot over in about a week, and i am trying to find a faster way to deal with this situation. Any suggestions?

fire your concrete crew, we hold ours to 1/8 in twenty feet
Too late to fire anyone plus I am just a sub, no power to choose other subs. I am sure that if problems from the slab affect other parts of my frame, and I miss them, I will be the one looking for a new builder to do work for, not the concrete contractor
shim the top of the load bearing wall under the second floor joists and rough all the doors an inch tall wth a 1x4 tear-out patch under the header.
