ECA Geophysics surveys are designed and performed by our senior geophysicist who holds an advanced degree (1984) in geophysics from the Colorado School of Mines - a top engineering and earth science school having a standalone geophysics department that trains geophysicists through a hands-on rigorous curriculum. To eliminate the establishment of expensive manual grids, ECA Geophysics can provide s
urveys that utilize DGPS guidance based upon geodetic coordinate systems such as the State Plane, WGS 84 or UTM. Our final deliverables are fully compatible with GIS and AutoCAD databases. Geophysical surveying services offered by ECA Geophysics include the following:
• Depth to bedrock and rippability (seismic refraction method)
• Subsurface soil properties for foundation design (seismic refraction method)
• International Building Code - National Earthquake Hazard Reduction Program (IBC - NEHRP) classifications (seismic refraction method)
• Buried utility locating (ground penetrating radar (GPR) method)
• Buried tank, drum and debris detection (electromagnetic induction (EMI) and magnetic methods)
• Landfill boundary delineation (EMI method)
