2. You are a staff engineer for a local geotechnical engineering firm. As part of the geotechnical exploration for a project, several subsurface tests have been conducted. You are given the results of one traditional soil boring with Standard Penetration Testing (SPT). The results of this boring, labeled as B-2, are presented on page 3 of this assignment. Based on testing of collected soil samples, the encountered soils have the unit weights listed in Table 1. Table 1. Summary of Soil Unit Weights from Boring B-2.
