ASCE 38 Utility Quality Levels quick reference
A one-page field-pocket reference for the four quality levels, the audit artefacts that travel next to each, the calibration log down-grade rule, and the bounded-negative rewrite — distilled from CI/ASCE 38-02 for crew leads, reviewers, and closeout editors.
- QL-A through QL-D criteria at a glance, with the defining line for each level
- Audit artefact per level (stamp + method-stack + depth + source) so a findings sheet holds up at audit
- Calibration log rule, bounded-negative four fields, and the down-grade rules built into the standard
One sheet. Four levels. The audit artefacts.
The PDF is intentionally thin — designed to be referenced on the tailgate, not read in the office. Every row throws the question a reviewer or crew lead should answer out loud before signing off a line.
QL-D records-only, QL-C records + one method, QL-B multi-method, QL-A potholed — one row per level so a field reviewer can read the assignment rules without flipping pages.
A stamp, a method-stack annotation, a calibration log reference, and a source — the four artefacts that travel next to every defensible closeout line, with the down-grade rule for any line that drops one.
Method stack, sweep length, calibration point, and frequency applied at the time of the pass — the four fields that turn an "absent" reading into a defensible finding rather than silence at audit time.
