SUBSURFACE UTILITY ENGINEERING

Mapping What's Underground with Confidence

Accurate Group specializes in providing comprehensive Subsurface Utility Engineering (SUE) services, encompassing Levels A through D. Our expertise ensures clients receive accurate and reliable information regarding underground utilities — critical for informed decision-making and effective project planning, reducing the risk of utility strikes and protecting project timelines and budgets. From non-destructive test-hole excavation to advanced geophysical designation, surface feature surveys, and thorough records research, our tiered methodology is tailored to match the level of confidence each project requires. By leveraging our expertise across all four levels of SUE, we provide comprehensive insights that enhance project safety, efficiency, and success. Our approach mitigates risks associated with utility conflicts and contributes to smoother project execution and better resource management, making Accurate Group a valuable partner in any construction or infrastructure initiative.

PROJECT HIGHLIGHTS

Key SUE Service Levels

Level A — Underground Utility Locating (Test Hole)

Non-destructive vacuum excavation for precise visual confirmation of utility locations.

Level B — Utility Designation

Advanced geophysical equipment used to map and record utility locations from the surface.

Level C — Visible Surface Feature Survey

Surface feature mapping combined with existing records for reasonable-accuracy utility location.

Level D — Record Research / Data Collection

Records-based research per ASCE 38-22 standards, providing a starting point for utility conditions.
