Sitemark handles compaction logging, grade verification, and superelevation documentation in one app. DOT inspectors get what they need before they ask for it.
Before the crew starts placing material, the field supervisor creates a lift job in Sitemark. Enter the lift name (Subgrade, Base Course, or Paving), the station range (e.g., 0+00 to 42+50), and the Proctor specifications from the project QC plan:
- Proctor method: Standard (T99) or Modified (T180) - Maximum dry density (PCF) from the Proctor test - Optimum moisture content (%) - Required compaction: 95% Standard Proctor (subgrade) or 98% Modified (base and paving)
Once set up, every compaction test logged against this lift automatically calculates percent compaction and compares against spec — no manual calculation, no lookup tables.
Multiple lifts can be active simultaneously when multiple crews are working different stations. Each lift tracks its own compaction and grade records independently.
As the nuclear gauge technician takes field density tests, readings are entered directly into Sitemark. For each test, log:
- Station and offset from centerline - In-place wet density (PCF) - Moisture content (%) - Calculated dry density (auto-computed) - Percent compaction vs Proctor max (auto-computed) - Pass or fail vs spec (auto-computed)
The technician sees pass/fail the moment the test is entered — no waiting to run numbers in the office. Failing areas are flagged on the station map immediately so the crew can rework and retest before the lift is approved.
Nuclear gauge serial number, operator certification number, and gauge calibration date are logged with each test session for full DOT audit traceability.
Sitemark applies your project-specific compaction spec to every test automatically:
- Subgrade: 95% Standard Proctor (AASHTO T99) — standard for most state DOTs - Base and subbase: 98% Modified Proctor (AASHTO T180) — required on most federally funded roads - Paving: typically 92–96% Marshall density or Rice specific gravity — configurable per project mix design
When a test fails, Sitemark flags the station, records the failure, and creates a rework record. When the area is reworked and retested, both the original failure and the corrective retest are retained in the record — the full audit trail DOT inspectors and FHWA auditors require.
Grade tolerance: ±0.05 ft on subgrade, ±0.03 ft on base, ±0.02 ft on paving surface. Applied automatically per lift type.
On curve sections, log superelevation readings at each station using a digital level or rod and level. Enter the outside edge elevation, inside edge elevation, and lane width. Sitemark calculates:
- Actual superelevation rate (%) - Design superelevation from your project data - Deviation from design - Pass/fail vs ±0.3% superelevation tolerance (configurable)
Runoff and runout transition stations are logged separately. The superelevation verification log is attached to the QC report and submitted to the DOT resident engineer with the compaction records.
Superelevation design values from AASHTO tables based on design speed and curve radius. Sitemark applies your project geometry — not generic tables.
When the lift is complete and all compaction tests and grade checks are passing, tap "Generate QC Summary." Sitemark produces a DOT-format QC Daily Summary in under 10 seconds:
- Compaction log: station by station, test result, Proctor reference, pass/fail - Grade verification: station by station, design vs actual, deviation, pass/fail - Superelevation verification (where applicable) - Equipment log: nuclear gauge serial, calibration date, operator cert - Lift summary: total stations tested, pass rate, failing areas reworked - QC technician certification block
DOT resident engineers reviewing this package authorize lift sign-off immediately. No overnight compilation, no callbacks asking for missing data.
Report format matches CDOT, TxDOT, and ADOT daily summary formats. State-specific formats available on Enterprise plan.
