Utility Locator Training Course

Lesson 1 • Underground Utility Systems Overview

Covers the major categories of buried utilities and their physical characteristics. Establishes the baseline knowledge needed to recognise what locators protect.

Lesson 2 • Consequences of Utility Strikes

Examines human, financial, and operational impacts of damaging buried utilities. Motivates rigorous locating practice by connecting errors to real-world consequences.

Lesson 3 • One-Call Notification System

Explains the mandatory pre-excavation notification process and stakeholder roles. Connects regulatory requirements to daily locating workflow.

Lesson 1 • Recognising Record Limitations and Conflicts

Addresses common discrepancies between records and actual field conditions. Prepares students to apply professional judgement when documentation is incomplete or contradictory.

Lesson 2 • Types of Utility Records

Surveys as-built drawings, GIS data, facility maps, and permit records. Teaches students to identify which document types are most reliable for each utility category.

Lesson 3 • Conducting a Pre-Field Site Assessment

Guides students through remote and on-site reconnaissance before equipment deployment. Reduces field surprises by identifying access issues and utility conflicts early.

Lesson 1 • Electromagnetic Theory Fundamentals

Introduces alternating current, magnetic fields, and induction as they apply to utility locating. Provides the conceptual foundation for all EM equipment operation.

Lesson 2 • Signal Distortion and Interference

Identifies sources of EM interference and explains how they corrupt locate data. Students learn to recognise and compensate for distorted signals.

Lesson 3 • Signal Transmission Methods

Compares direct connection, inductive clamp, and broadcast transmission techniques. Students select the appropriate method based on utility type and site conditions.

Lesson 1 • Equipment Calibration and Setup

Establishes correct calibration procedures before each locate session. Ensures equipment accuracy and reduces systematic errors in field data.

Lesson 2 • Equipment Maintenance and Troubleshooting

Teaches routine maintenance schedules and common fault diagnosis for EM equipment. Minimises downtime and extends equipment service life.

Lesson 3 • Transmitter Types and Functions

Surveys portable transmitters, signal generators, and clamp-on devices used in utility locating. Students match transmitter capabilities to specific field applications.

Lesson 1 • Depth Estimation Techniques

Covers 45-degree method, peak-to-null, and manufacturer depth functions for estimating burial depth. Students apply and cross-check multiple methods for confidence.

Lesson 2 • Systematic Locate Workflow

Establishes a repeatable step-by-step process from site arrival to mark completion. Reduces omissions and ensures all utilities within the dig area are addressed.

Lesson 3 • Marking Utilities in the Field

Covers colour-coding standards, marking materials, and placement conventions for surface marks. Ensures marks are interpretable by excavators and meet industry standards.

Lesson 4 • Tracing and Pinpointing Utilities

Develops precise tracing technique along utility routes and accurate centreline pinpointing. Directly determines mark placement accuracy in the field.

Lesson 1 • GPR Operating Principles

Explains radar wave propagation, reflection, and return signal interpretation in subsurface media. Provides the physics foundation for all GPR equipment operation.

Lesson 2 • Radargram Interpretation

Builds skill in reading radargrams to identify utility hyperbolas, voids, and anomalies. Connects visual pattern recognition to confident utility identification.

Lesson 3 • GPR Equipment Setup and Operation

Covers antenna selection, system configuration, and data collection procedures for utility surveys. Students produce clean, interpretable radargrams in the field.

Lesson 1 • Digital Reporting Tools and Platforms

Introduces mobile apps, GPS-enabled reporting systems, and cloud-based locate management platforms. Students enter, sync, and retrieve locate data using digital tools.

Lesson 2 • Locate Reports for Complex Sites

Addresses multi-utility, multi-day, and conflict-site reporting requirements. Prepares students to produce professional reports for high-stakes or disputed locates.

Lesson 3 • Positive Response and Ticket Closeout

Covers the positive response process for notifying excavators and one-call centres of locate completion. Ensures legal compliance and clear communication of locate status.

Lesson 1 • Damage Investigation and Root Cause Analysis

Teaches students to analyse utility strikes to determine contributing factors and prevent recurrence. Builds a learning culture around near-miss and damage events.

Lesson 2 • Industry Standards and Best Practices

Surveys consensus-based industry standards governing locate quality, marking, and documentation. Connects professional standards to daily decision-making in the field.

Lesson 3 • Continuous Improvement in Locating Practice

Establishes habits of self-assessment, skill development, and technology adoption for career-long growth. Positions students as proactive professionals in an evolving field.
