Pardon the pun, but geophysical surveys can be the bedrock of today’s environmental projects. Applications range from locating abandoned underground storage tanks and utilities, to complex mapping of geology in remedial investigations, to finding landfill boundaries and other buried unknown problems.
A tremendous amount of effort is focused on collecting data about the Earth’s surface using satellites, airplanes, terrestrial mobile mapping units, total stations and many other devices. Even land areas under water are measurable up to a certain depth. It is reasonable to say that we are at the point where nearly everything above ground is mapped.
The slogans “Call before you dig” and “Know what’s below” are familiar reminders of the importance of verifying the location of all kinds of subsurface utility infrastructure before excavation takes place. It only takes a moment for a pipeline or conduit to be damaged by heavy equipment, potentially causing public safety issues and disruption of service; thus the need for subsurface utility engineering (SUE).
While there are many technologies and services used to acquire critical data associated with railways and their rights-of-ways, some can be cumbersome and require logistical challenges that can increase risk to track workers.
With 3D printing on the verge of going
mainstream, 3D motion control making gaming
more realistic, and 3D design tools aiding
the visualization of everything from
buildings and infrastructure to underground
pipelines, 3D innovation is everywhere.
7-year-old son has a wonderful imagination and is always thinking of new
inventions. “I’m going to find a way to capture lightning and turn it into free
electricity for people to use,” he said to me the other day.
For decades, California's Hetch Hetchy water system has supplied water to the San Francisco Bay Area. But the aging system is nearing the end of its useful life and is seismically vulnerable. Constructing a solution requires accurate, nerve-racking surveying.
