The most expensive problem in construction is a foundation that does not match the soil. Footings designed without geotechnical data rely on presumptive bearing capacities from the building code — generic values that may or may not reflect what is actually under your building. When the soil is weaker than assumed, you get settlement. When there is expansive clay nobody tested for, you get heaving. When the water table is higher than expected, you get hydrostatic pressure against basement walls that were not designed for it. These are not hypothetical problems — they are the problems we see on projects where geotechnical engineering was skipped or outsourced to a firm that had no communication with the structural engineer.

BOZ Engineering Group eliminates this disconnect by providing geotechnical and structural engineering under one roof. When our geotechnical team conducts a subsurface investigation, the data goes directly to the structural team designing the foundation. Bearing capacity, settlement estimates, groundwater conditions, and soil classification inform the foundation type, footing size, embedment depth, and drainage requirements in real time. There is no waiting for a report from a third-party firm, no misinterpreting recommendations, and no designing a foundation based on assumptions that the geotech report later contradicts.

Geotechnical investigation fees depend on the number of borings, depth of investigation, and complexity of subsurface conditions. Every project receives a fixed fee proposal before field work begins — residential and commercial scoped individually. Turnaround is 2 to 4 weeks from field investigation to final report.
