This work involves performing a geotechnical investigation by boring, sampling, and testing of the soil and rock strata to establish the soil and rock foundation characteristics for the analysis for the design of highway and bridge projects, when the soil and rock properties may affect subgrade and foundation performance. In addition, this work may include: 1. Locating bedrock 2. Searching for sources of aggregate and borrow for use in highway construction. 3. For projects requiring Section 408 USACE coordination, Drilling and Invasive Program Plans and additional required submittals for Section 408 permission/technical reviews including, but not limited to, liquefaction susceptibility, subsurface investigation, seepage analysis, settlement analysis, stability analysis, etc.
