Private utility designation and locating
Electrical, gas, water, sewer, fiber-optic, telecommunications, and irrigation infrastructure — designated and documented on the project site.
Specialist subsurface investigation, documented to the highest standard
Utility designation with engineering-level documentation for projects that call for pre-construction intelligence.
Utility designation / GPR / mapping
Services
Verification and confidence-classified findings run through every investigation.
SafeLine focuses on three verified service lines, each documented as a defensible record.

GPR investigation
Specialist investigation of subsurface conditions with interpreted, confidence-classified findings.
Utility mapping and engineering-level documentation
KMZ files, mapping, and verification recommendations structured for downstream teams.
Service fit
Which investigation fits the project decision?
The right scope starts with the infrastructure, evidence, and downstream decision—not with choosing a piece of equipment.
01
Private lines may cross planned work
- Investigation
- Private utility designation using field methods suited to the site.
- Usable record
- Surface designation and scoped documentation.
- Decision supported
- Plan excavation, grading, drilling, or construction around the available evidence.
02
A line is untraceable or conditions are unclear
- Investigation
- GPR investigation where the project question and site conditions support it.
- Usable record
- Interpreted, confidence-classified findings.
- Decision supported
- Understand anomalies and decide where further verification may be needed.
03
Field findings must travel downstream
- Investigation
- RTK-positioned mapping and documentation designed for the recipient.
- Usable record
- Utility map, KMZ, congestion context, or intelligence report.
- Decision supported
- Coordinate contractors, engineers, owners, and facility teams around a usable record.

Pre-construction workflow
How services fit the pre-construction workflow
Every investigation is delivered with confidence-classified findings, RTK GPS precision, and documentation prepared for contractor and engineering firm workflows — pre-construction intelligence, structured as a planning input.
ASCE 38-aligned methodology
01Investigate
Field methods matched to the site and infrastructure in question.
02Capture
Findings positioned with RTK GPS precision.
03Classify
Confidence stated instead of presenting uncertainty as exactness.
04Document
Records prepared for contractor and engineering firm workflows.
