Summary
This abridged consensus standard classifies existing subsurface utility information into quality levels A–D. It sets out engineer and owner tasks, combining records research, surveyed surface features, geophysical tracing and minimally intrusive exposure. It also addresses mapping conventions, deliverable formats and the relative costs and benefits of improving data reliability.
Classifications: Risk management; risk evaluation.
Classifications: Underground utility damage prevention.
Classifications: Excavation; trenching.
Classifications: Underground utility locating and verification.
Classifications: Construction; construction industry.
Summary
The guideline defines quality levels and methods for locating, depicting and managing subsurface utility information to reduce construction risk.
Themes: control of work, structural and asset integrity.
