Log grade shots in the field, compare to design grade instantly, and generate as-built reports before the crew demobilizes. Catch out-of-tolerance pads while the dozer is still on site — not three days later when a surveyor finds them.
Machine control gets the grade close. Verifying it requires pulling shots into a spreadsheet, comparing to design, and hunting down deviations manually. On a large site that process runs multiple days — while the crew idles or moves to the next area without confirmed sign-off.
When a surveyor finds a non-compliant pad at final certification, the grading equipment is gone, the mobilization cost is on you, and the schedule is blown. By the time rework happens, the correction is three times more expensive than catching it during the original grade.
Paper shot notes have no timestamp, no GPS coordinate, and no chain of custody. When an inspector disputes a grade or an owner questions an as-built elevation, there is no way to prove when the measurement was taken or who took it.
Sitemark compares each shot to design grade the moment you enter it. No spreadsheet, no manual calculation. Deviations over tolerance are flagged in red before you leave the pad.
The deviation report runs in real time. If pad 47 is 0.08 ft high and tolerance is 0.05 ft, you know before the operator shuts down. The fix takes ten minutes instead of a remobilization.
Sitemark records who took the shot, when, and where — permanently. The audit trail is immutable. When questions come up at closeout, the record stands on its own.
Enter or import field shots; deviation from design calculated automatically.
One-click PDF showing every shot, design elevation, measured elevation, and pass/fail.
Professional as-built document ready for inspector, owner, or surveyor review.
Bring in total station or GPS data collector exports without reformatting.
Organize shots by pad, area, or phase within a single job — no separate spreadsheets per area.
Add compaction tests to the same job — linked shot data and compaction records in one report.
We had 2,400 piles on a 200-acre solar site. Before Sitemark, two guys were manually pulling shots into a spreadsheet and comparing to design for three days straight. Now the deviation check runs in the field and we have a compliant as-built before the crew demobs. Four hours, not three days.

Typical finished subgrade tolerance is ±0.05 ft (0.6 in) from design grade. Base course is usually ±0.03 ft. Tolerances vary by project specification and owner — always check the geotechnical or civil plans. Sitemark lets you set the project tolerance at job setup and automatically flags shots outside it.
Grade verification documentation includes the design elevation at each shot point, the measured elevation, the deviation, and a pass/fail determination relative to the project tolerance. Inspectors expect a report organized by pad or area with shot point coordinates, elevations, and deviations clearly tabulated. Sitemark generates this report automatically from field shots.
Sitemark imports CSV exports from Trimble, Topcon, and other total station and data collector systems. Upload the CSV, map columns to Sitemark fields, and the deviation report generates automatically against your design surface.
By checking pad elevations in the field against the approved grading plan before the grading crew demobilizes, Sitemark lets crews correct out-of-tolerance pads on the same visit. This eliminates the cycle of surveyors discovering non-compliant pads at final certification, calling for rework, and returning for a paid recheck.
Sitemark gives grading contractors the tools to catch deviations before the equipment leaves and hand over a clean as-built without the spreadsheet work.
