Log compaction tests lift-by-lift with all required DOT QC fields. Verify grade by station with automatic deviation flagging. Generate DOT-formatted QC records that pass first-submission review.
A missing test record, a failed test without a re-test, or a gauge calibration date not on the record — any of these is grounds for DOT rejection at closeout. Finding the gap after the QC submittal costs weeks of delay and, in some cases, requires re-testing.
Logging grade shots by station on paper — recording station, offset, design grade, field elevation, and deviation for every point — is slow, prone to transcription errors, and produces records that do not automatically flag out-of-tolerance locations.
A gauge calibration that expires during a project means every test taken after expiry may be rejected. Tracking calibration dates across multiple gauges on multiple projects by memory or paper calendar is how calibration gaps happen.
Sitemark prompts for every required DOT QC field in sequence. Percent compaction and pass/fail are calculated automatically. No field is skippable. The complete chain — failed test, corrective action, passing re-test — is required before a lift can be closed.
Log grade shots by station and offset. Sitemark compares each shot to design grade and flags out-of-tolerance locations in real time. The station coverage map shows which stations have passing records and which have open deviations.
Register nuclear gauges in the equipment registry with calibration dates. Sitemark auto-populates the calibration date on every test record and sends expiry alerts before the calibration window closes.
Log all required DOT QC fields — station, lift, material, moisture, density, percent compaction — with automatic pass/fail.
Log grade shots by station and offset; deviation from design flagged automatically.
Generate compaction QC report in DOT-accepted format — ready for digital or paper submittal.
Failed tests require corrective action documentation and linked re-test before lift closure — permanent audit trail.
Track calibration dates per gauge; auto-populate on test records; alerts before expiry.
Log station-based grade shots and compaction tests under the same job — single closeout package for DOT submittal.
We run machine control on dozers and motor graders. When the blade cuts a finished subgrade, I need to verify the design surface tolerance before we pave. Sitemark lets me log verification shots, compare to the design file, and print a stamped-ready report. The paving sub used to wait on us. Now we hand them the report the same day.

DOT QC plans require: test date and time, station and offset, lift number and material type, test method (AASHTO T99 or T180), nuclear gauge serial number and calibration date, moisture content, wet density, dry density, Proctor maximum dry density, percent compaction, pass/fail status, and the technician name and certification number. Missing any field is grounds for record rejection.
A failed test triggers stop-work on the affected station range. The contractor identifies the failure cause, takes corrective action, re-compacts, and re-tests. Both the failed test and the passing re-test — with corrective action documented — must be in the QC record. Missing the corrective action chain blocks project closeout.
Typical DOT tolerances: subgrade ±0.05 ft from design grade; base course ±0.03 ft; paving ±0.02 ft. Tolerances vary by state DOT and project type. Sitemark flags every grade shot outside tolerance in the station-based verification report.
Sitemark includes an equipment registry where gauge serial numbers and calibration dates are stored. The calibration date auto-populates on every test record and Sitemark alerts before calibration expiry — preventing the closeout finding of calibration records missing from the QC submittal.
Sitemark gives road contractors the tools to build complete, defensible QC records in the field and generate DOT-formatted reports that hold up at closeout review.
