History
Subsurface Utility Engineers, LLC
Subsurface Utility Engineers, LLC is a Hawaii-based geophysical and subsurface utility firm headquartered in Honolulu, proudly serving Oahu, Maui, Hawaiʻi Island, and Kauai. We specialize in delivering accurate, non-invasive subsurface data that helps our clients build safely, responsibly, and with confidence.
With Hawaii’s unique geology, dense infrastructure, and cultural sensitivity requirements, subsurface investigation demands experience, precision, and respect. Our team combines state-of-the-art technology, certified technicians, and local knowledge to support projects of all sizes—from small renovations to major infrastructure and military developments.
What We Do
We provide a comprehensive range of geophysical and subsurface utility engineering services, including:
- Ground Penetrating Radar (GPR)
- Electromagnetic pipe and wire locating
- Concrete scanning for rebar and post-tension cables
- Vacuum excavation and potholing (daylighting)
- LiDAR and laser scanning
- Utility mapping and as-built verification
Our services reduce risk, prevent utility strikes, protect cultural resources, and improve project efficiency.
Our Commitment to Safety & Cultural Responsibility
Operating in Hawaii requires more than technical expertise—it requires respect for the land and its people. We use non-destructive investigation methods whenever possible to help identify potential subsurface conflicts, including Hawaiian iwi kūpuna (ancestral remains), prior to excavation. Our work supports compliance with Hawaii State Historic Preservation Division (SHPD) guidelines and helps clients meet cultural monitoring and preservation requirements while keeping projects on schedule.
Our Mission
To provide safe, accurate, and culturally responsible subsurface utility and geophysical services that protect people, infrastructure, and Hawaii’s cultural resources—while helping our clients build with confidence.
