You’ve finally reached the construction stage of your project. Excavators have arrived and they’re powered up. Suddenly, an excavator hits a shallow ridge of rock not identified during preconstruction investigations. And now the project timeline is affected, not to mention budget concerns are cropping up.

Enter geophysical investigations. This type of survey occurs before (or during, if needed) a project to minimize unexpected problems during the design and construction phase of a project. Better yet, these investigations are non-intrusive and non-destructive, using both highly educated staff and advanced, specialized equipment.

RETTEW completed the asset purchase of Enviroscan, a geophysical survey company that’s worked around the globe to detect and map underground, underwater, or otherwise hidden targets. This work helps your projects move ahead faster, safer, more easily, and with less cost. The addition of Enviroscan’s geophysics expertise seamlessly integrates with our reputation for geotechnical investigations, environmental permitting expertise, and subsurface utility engineering.

Geophysics services can detect subsurface features such as utilities, sinkholes, drums, underground storage tanks, contaminant plumes, rock ridges, and graves, among other things. Proactively investing in geophysical insights will prevent project delays, change orders, and accidents.
