Geophysical Studies. At CRA, we stress the use of multiple survey techniques to gain maximum information in a cost efficient manner. No matter the technique, we emphasis using high speed, high-density data collecting field equipment and up-to-date processing software that allows us to continually increase the utility and accuracy of geophysical survey data. In addition to this advantage, they are able to overcome some of the problems of sampling posed by systematic shovel testing coverage and can be considerably faster than shovel testing. When used correctly in combination with analysis of cartographic resources and other background data, the results of a geophysical survey may be used to make decisions about how to best deploy more cost-intensive field operations such as shovel testing, sample block excavation, strip plowing, and dozer scrapes.
Environmental Site Assessment. What are geophysical soil exploration methods? Geophysical methods, which are widely used in highway work and in other applications, can be implemented more quickly and less expensively and can cover greater areas more thoroughly.
