2 The Earthwork Record System serves as the system that construction inspectors utilize to record test results. When properly maintained for each project and attested to by responsible personnel, it is used by the Department as the basis for accepting the completed roadway earthwork.

5 For example: At the top of the page it takes___ lifts to build the backfill up from the bottom of the sump to the bottom of the pipe. Then it takes _____ lifts to cover the pipe. Finally, it takes another _____ lifts to get to the top of the tallest remaining structure (S-1). The tallest remaining structure is the structure with the largest number of lifts remaining above the pipe. S-1 has _____ lifts above the pipe and S-2 has _____ lifts, therefore, we use S-1's lifts in determining the number of lifts needed.
