Reduce project risk, limit surprises, and save money with Urban X infrastructure intelligence

A comprehensive and detailed map of an existing underground utility network is beneficial to any design/construction project. Incorporate Subsurface Utility Engineering (SUE) into your next project and reveal the local underground utility network and other concealed features that could impact your design.

The SUE Process

SUE is an engineering process following the ASCE 38-02 guideline to ascribe attributes to underground utility information via four Quality Levels (QL). This process provides design teams with professionally stamped composite subsurface utility drawings. Better information means a better design which leads to more effective, productive, and safer construction.


Utility Record Research

Systematically contacting facility owners to obtain their information and rendering these data on a digital base plan


Appurtenance Survey

A digital field survey of all visible utility appurtenances.


Geophysical Survey

A digitally captured field survey to verify the utility record information and designate the actual position of known and unknown underground utilities within the work area.


Physical Exposure of Target Utilities

Typically completed by vacuum excavation where precise horizontal and vertical measurements (location, elevation, extent, width, depth, thickness, composition, etc.) are mission-critical to your design considerations.

Urban X has a variety of SUE project experience for upgrades or new installations of conveyance systems, including watermains, forcemains and trunk sewers

See Case Study

Existing Wastewater and Water Treatment plants can have a very complex local underground utility network. The professionals at Urban X have delivered many SUE projects to assist with upgrades, retrofits, substantial additions or improvements.

See Case Study

With on-going improvements to transportation infrastructure, the existing underground utility network can be fully understood at the design stage to mitigate construction surprises.

See Case Study

These larger projects require continued focus, experience and project team flexibility to maximize design and construction efficiency.

See Case Study

With any development, especially re-purposing lands for alternative uses, the existing underground network needs to be understood with regards to existing servicing and capacities to ensure appropriate adjustments are engineered during design.

Founded in 2017, Urban X is exclusively focused on providing Subsurface Utility Engineering (SUE) services and the application of geophysical technologies for underground imaging. We strive to be the most reliable provider of accurate underground infrastructure intelligence in Ontario.

Focused on providing clients with accurate and reliable underground utility information, our data is secured through documented processes to ensure a comprehensive understanding of underground structures and facilities. Field verification is completed with the latest available technologies. All information is captured and rendered using industry best practice guidelines, ASCE 38-02 and CSA S250-11.

The Urban X team has completed hundreds of SUE projects for public and private sector clients since 2017, however, many of our key team members have been affiliated with each other in the delivery of SUE projects for more than 20 years and bring that extensive experience to every assignment. We remain focused on the delivery of professional SUE services and continue to provide transformative digital measurements and strengthened project delivery capabilities that our clients have come to expect.
