Radiology for the earth.
You’ve finally reached the construction stage of your project. Excavators are onsite and 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 the budget.
In retrospect, you realize you should have invested in geophysical investigations (sometimes called scans). When you encounter unwelcome underground surprises, geophysical scanning can help you define the problem so you can find the fastest and most cost-effective solution. Better yet, this type of survey should occur before the design phase of the project. In fact, an analysis shows that for every dollar invested in geophysics at the start of a project, $7 are saved over the course of later phases. Best of all, these investigations are non-intrusive and non-destructive.
RETTEW completed the asset purchase of Enviroscan, a geophysical survey company with highly trained staff and advanced specialized equipment. They have worked around the globe to detect, scan, and map underground, underwater, or otherwise hidden targets. This work helps your projects move ahead faster, safer, smoother, 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.
Great people; great science.
Imaging geophysical surveys can detect subsurface features such as utilities, sinkholes, drums, underground storage tanks, contaminant plumes, rock ridges, graves, and many other features. Parametric geophysical investigations measure important physical properties of the subsurface such as corrosion potential, bearing capacity, seismic amplification and liquefaction potential, clay or water content, density variations, etc.
Preemptively investing in geophysics will prevent surprises and project delays, change orders, and accidents, and can reduce your liability.
