Utility Locate & Marking QA Logger
811/one-call locate quality log — mark accuracy, color code, clearance vs as-builts, mismarks and near-miss documentation; offline + GPS.
New locate ticket inspection
QA a sample of tickets weekly; document 100% of mismarks and every near-miss or strike, same day, with photos.
Field guide: Utility Locate & Marking QA Logger
A utility strike costs on average thousands of dollars and occasionally a life, and the damage-prevention system that prevents it — one-call tickets, APWA color-coded marks, tolerance-zone hand digging — only improves when mismarks and near-misses get documented instead of cursed at and buried. This logger is the documentation half: per ticket, which utility, how the mark was verified (potholing being the gold standard), the measured offset, and what happened.
The offset field turns QA into data: most state laws define a tolerance zone of roughly 450–600 mm either side of the mark within which excavation must be careful/hand methods. Marks beyond tolerance, unmarked utilities, and no-show responses are exactly the records that damage-investigation and locator-performance reviews require — with the GPS pin and date this log attaches automatically.
Field tips
- Photograph marks against a tape measure before digging; faded paint and regraded soil erase the evidence by the time anyone asks.
- Treat every 'marked but nothing there' seriously — overmarks teach crews to distrust marks, which is how real strikes happen later.
- Abandoned lines are the classic trap: log when an exposed line doesn't match the marked utility's size/material — it may be live elsewhere.
Records are stored only in this browser (localStorage) — export regularly. This tool aids field documentation; it does not replace your agency's official inspection procedures or engineering judgment.

Frequently asked questions
What do the APWA mark colors mean?+
Red = electric; yellow = gas/oil/steam; orange = communications; blue = potable water; green = sewer/storm; purple = reclaimed/irrigation; pink = temporary survey; white = proposed excavation. Wrong-color marks are a real finding — a comms line marked yellow changes how a crew behaves around it.
What is the tolerance zone?+
The buffer around marks (typically 450–600 mm / 18–24 in each side, per state law) within which mechanical excavation is restricted — hand tools, vacuum or soft digging only until the utility is exposed. The measured-offset field exists to test marks against this zone: a utility found outside it is a reportable mismark in most states.
Why document near-misses that caused no damage?+
Because they're free lessons with full evidence: same root causes as strikes (mismark, no-show, crew skipping potholing) without the repair bill. Programs that log near-misses systematically — like CGA's DIRT does industry-wide — see real strike reductions; programs that only record damage learn only from disasters.
What should happen after an actual strike?+
Safety first (gas: evacuate, no ignition, call emergency line; electric: treat as energized), then notification per law — the utility, the one-call center, often a state authority. Then documentation: photos, the ticket, marks vs actual location with measurements. This log holds the field half; the formal report mirrors it.
