Private Utility Locating

Public 811 one-call locates only cover utilities owned by member operators — leaving private utilities unmarked and your crew at risk. UDI's private locating service identifies and marks all subsurface utilities on your site, including privately owned lines that 811 won't touch.

What's included

Electromagnetic (EM) detection of buried conductors
Ground-penetrating radar (GPR) scanning
Private utility marking and mapping
Pre-excavation clearance documentation

On-Site Documentation

Thorough documentation before, during, and after excavation is your best protection against disputed claims. Our field technicians capture the photographic, written, and spatial records that establish a clear, defensible project history.

What's included

Pre-construction site condition surveys
Excavation progress photography and video
Utility exposure documentation
Post-incident scene documentation

Utility Conflict Analysis

When design drawings and field conditions don't match, conflicts arise — and conflicts cost money. UDI analyzes utility data against your project plans to identify potential clashes before they become expensive change orders or damage incidents.

What's included

Design vs. field utility comparison
Horizontal and vertical conflict identification
Conflict resolution recommendations
Coordination with design engineers

Leak Detection

Undetected leaks in water, gas, or other pressurized utility systems can cause catastrophic damage and project delays. UDI's leak detection services use proven acoustic and tracer-gas methods to pinpoint leaks quickly and accurately.

What's included

Acoustic leak detection for water and gas lines
Tracer gas leak location
Pressure testing support
Leak location reporting and mapping
