Is there a typical soil resistivity for Pittsburgh?+
No citywide value can represent a parcel, substation, route, or facility. Pittsburgh’s ridge-and-valley terrain includes residual soils over sandstone, shale, and limestone, river alluvium, mine-influenced ground, and heavy urban or industrial fill. Wenner corridors can change material, drainage, and access quickly. Field measurements must be tied to the actual array, location, spacing, orientation, and current condition.
Does Wenner electrode spacing equal test depth?+
No. Larger spacing generally samples a larger earth volume, but spacing is not an exact one-to-one depth. Layering, array geometry, site boundaries, and conductive features affect the apparent response.
What information is needed to scope a Pittsburgh survey?+
Send the site plan, survey objective, grounding or corrosion design request, proposed stations and spacings, final grading information, candidate line corridors, utility-clearance responsibility, access rules, schedule, and required report format.
Can Calicore mobilize outside California?+
Yes. Calicore performs project-based Wenner field programs throughout the United States when the station count, spacing, access, schedule, and mobilization are practical.
