Subsurface Information Modeling (SIM)
UES provides Subsurface Information Modeling (SIM) services to help owners, architects, engineers, contractors, developers, municipalities, and agencies better visualize, coordinate, and manage underground infrastructure information. Often referred to as Underground BIM, SIM transforms subsurface utility data into a visual, data-rich model that supports more informed planning, design, and construction decisions.
By enhancing Professional Utility Locating and Subsurface Utility Engineering (SUE) findings with 3D modeling, UES helps project teams better understand what exists below the surface, evaluate potential conflicts, improve coordination, and reduce uncertainty before construction begins.
What is Subsurface Information Modeling?
Subsurface Information Modeling (SIM) is the process of converting utility locating, geophysical survey, and SUE data into a 3D model that represents underground conditions. These models can include known and interpreted utilities, subsurface features, utility corridors, conflict areas, depth information, and other data that supports design and construction coordination.
SIM gives project teams a more complete view of subsurface infrastructure than traditional 2D drawings or field markings alone. By visualizing complex utility networks in a digital environment, owners, engineers, contractors, and stakeholders can better understand potential conflicts and make more confident decisions earlier in the project lifecycle.
UES Subsurface Information Modeling services may include:
- Conversion of Professional Utility Locating and SUE data into a visual, data-rich subsurface model
- 3D representation of underground utilities, utility corridors, and subsurface features
- Integration of Quality Level data from SUE investigations when available
- Visualization of potential utility conflicts, clearance concerns, and design coordination issues
- Incorporation of geophysical survey results, field markings, test hole data, records, and project documentation when provided
- Development of standalone Subsurface Information Models or integration with BIM platforms
- Deliverables compatible with Civil 3D, Navisworks, Revit, or other project coordination workflows when appropriate
- 2D and 3D digital deliverables, model views, clash documentation, reports, or coordination exhibits
- Support for planning, design development, constructability review, utility coordination, and construction risk mitigation
Why it Matters
Underground utility conflicts can be difficult to understand when information is spread across field markings, records, 2D plans, test hole logs, and separate utility maps. SIM brings this information together in a more visual and coordinated format, helping project teams see relationships, conflicts, and constraints more clearly.
Subsurface Information Modeling helps clients:
- Visualize complex underground utility networks
- Identify potential clashes before construction begins
- Improve coordination between owners, designers, contractors, utility owners, and agencies
- Reduce uncertainty during planning and design
- Support better constructability reviews and utility conflict resolution
- Improve communication with stakeholders using clear visual deliverables
- Integrate subsurface data with broader BIM and virtual design workflows
- Reduce the risk of utility-related delays, redesign, change orders, and field conflicts
By converting subsurface data into actionable digital models, SIM helps project teams move from scattered information to a clearer, more coordinated understanding of underground conditions.

Frequently Asked Questions
What is Subsurface Information Modeling?
Subsurface Information Modeling, or SIM, is the process of transforming subsurface utility, geophysical, and SUE data into a visual, data-rich model that helps project teams understand underground conditions and coordinate design or construction decisions.
Is SIM the same as Underground BIM?
SIM is often referred to as Underground BIM because it applies building information modeling concepts to below-ground infrastructure. It helps represent utilities, subsurface features, conflict areas, and related data in a coordinated digital model.
What data can be included in a Subsurface Information Model?
A Subsurface Information Model may include utility locating data, SUE quality level information, geophysical survey results, test hole data, utility records, as-built drawings, field markings, depth information, and other project-specific documentation.
Can SIM be integrated with BIM platforms?
Yes. SIM deliverables can be provided as standalone models or integrated with Building Information Modeling platforms such as Civil 3D, Navisworks, or Revit to support broader design and construction coordination.
How does SIM help reduce construction risk?
SIM helps project teams visualize underground utility networks, identify potential clashes before construction, improve stakeholder communication, and reduce uncertainty during planning and design. This can help reduce utility-related delays, redesign, change orders, and field conflicts.
