DOT Work Has Specific Documentation Requirements
DOT road contractors face documentation requirements that most construction apps aren't designed for: nuclear gauge compaction logs with station references, grade verification at specified intervals, equipment calibration records, and QC daily reports in a specific format. Software that handles residential construction documentation often falls short for DOT compliance.
State DOT compaction documentation is more rigorous than commercial or residential work. Tests must be tied to station and offset, referenced to the current road design, recorded at specified frequencies per lift, and compiled into a QC daily report that the QC manager signs daily. In many states, this documentation is reviewed by the resident engineer before payment is processed.
The nuclear gauge itself must be calibrated — and calibration records must be current and available on demand. A gauge with an expired calibration certificate cannot legally be used for DOT work, and any compaction data recorded with it may be rejected retroactively.
Road grade verification requires shooting actual subgrade and pavement elevations at station intervals and comparing against the design template. Cross-sections showing actual vs. design cut/fill are used for final quantity calculations and payment. DOT inspectors may walk the grade with the contractor before accepting lifts, so real-time verification matters.
Superelevation documentation — verifying that banked curves achieve the design cross-slope — is another grade verification requirement specific to highway work that most construction apps don't address.
Both handle general construction daily reports and photo documentation. Neither supports nuclear gauge compaction logging with station references, DOT QC report formats, grade verification with design comparison, or equipment calibration tracking. For a DOT job, you'd need separate spreadsheets and manual processes for the grade and compaction documentation layers.
Heavy civil accounting and cost control platforms handle payroll, equipment hours, and earned value for DOT contractors. They're not field verification tools — they don't log grade shots, verify compaction against spec, or generate QC daily reports in DOT format. Use them for cost management alongside a field verification tool.
Sitemark handles the field verification layer that DOT work requires: grade shots at stations with design comparison, compaction percent calculation, equipment calibration tracking with expiration alerts, and QC daily report generation. The superelevation calculator verifies banked curve cross-slopes against design. Calibration records are stored and accessible for inspector review on demand.
Compaction data collected with an expired nuclear gauge calibration may be rejected — retroactively — by the resident engineer. If that happens after a lift has been accepted and paved over, the contractor may face costly re-testing or pay adjustments. Most contractors track calibration dates in a spreadsheet or rely on memory, which creates real compliance risk on multi-month DOT projects.
Sitemark's calibration tracking stores all equipment calibration records, sends alerts when calibration is approaching expiration, and makes records accessible for inspector review from the field. For DOT work, this is a direct risk reduction.
