The sum of foresight (FS) and adjusted cut (ADJ CUT) is used to verify which trench attribute?

The main idea is using survey readings to pin down the bottom elevation of a trench so you can check its vertical depth and how that bottom line changes along the trench. By adding the foresight reading to the amount you must cut (adjusted cut), you get the actual elevation of the trench bottom relative to the reference point. That bottom elevation is what tells you how deep the trench is compared to the planned depth, and it also shows whether the bottom sits on the intended slope as you move along the trench. If the bottom elevations line up with the design across the length of the trench, the gradient is verified. This method isn’t about operator ability, nor is it primarily about the trench’s length or its load-bearing capacity; it’s about confirming the trench’s depth and its gradient.
