UMS employs a strategic subsurface utility engineering (SUE) methodology structured in phases to ensure accurate mapping of subsurface utilities for infrastructure projects. The initial phase, or Phase I, provides a 2D map of existing utilities through record research and field investigations, aiding in design and conflict resolution. UMS aims to set new benchmarks in the industry by enhancing the reliability and safety of infrastructure development.

2. The Strategic Approach
UMS's strategic SUE methodology is
structured in phases, each escalating in the
intensity of designation and delineation.
This approach ensures a comprehensive
and accurate mapping of subsurface
utilities, which is crucial for the planning
and executing of infrastructure projects.

3. The Cornerstone of SUE
A critical component of UMS's strategy is the Phase
I operation, also known as utility designating or
Quality Level (QL) B mapping effort. This initial
phase provides designers with a 2D map of existing
utilities. This map is an amalgamation of meticulous
record research and field investigations, employing
conventional pipe and cable locators in conjunction
with GPS survey methods.

4. Navigating Through the
Quality Levels
Phase I's data set often presents a blend of
QLs as per CI/ASCE 38-02 standards:
QL D and C for installations are not easily
detectable with standard electromagnetic
(EM) equipment.

5. Implications for Design and
Conflict Resolution
The data acquired from Phase I is vital for the project
design team. It aids in preliminary design, conflict
evaluation, and pinpoint locations, necessitating
more detailed data. This approach streamlines the
design process and significantly reduces the risk of
conflicts and redesigns.

6. UMS: A Standards-
Driven Pioneer
UMS stands out as a standards-driven
organization, continually redefining how
organizations capture, measure, and memorialize
client infrastructure. UMS is setting new
benchmarks in the field through its strategic SUE
approach, ensuring more reliable, efficient, and
safer infrastructure development.
