FAQ · Fairfax County
Do I need a geotechnical report before building?
Most commercial permits, lenders, and structural engineers require a geotechnical report to establish allowable bearing pressure and foundation type. It is the least expensive insurance a foundation can have.
How long does a geotechnical investigation take?
A typical light-commercial site runs one to two weeks from drilling to final report, depending on lab test turnaround and access conditions.
