The test borings will be drilled using dry auger methods until groundwater is observed or caving soils were encountered. When groundwater is encountered the levels will be allowed to stabilize for approximately 15 minutes. The soil borings will be logged and sampled by an experienced geotechnical engineering technician. Soil samples will be obtained continuously to fifteen (15) feet and deep borings to twenty feet (20) and 5 feet intervals thereafter. Undisturbed samples of cohesive soils will be obtained using 3-inch diameter seamless Shelby tubes pushed to 2-feet increments. The extruded samples will be wrapped in protective foil and transported to our laboratory. Field shear strengths of the clays will be measured in the field with a hand penetrometer and correlations between this data and laboratory shear strength data will be made during analysis. Standard penetration tests (SPT) will be performed in low cohesion silts and sands. We will record the driving resistance while performing the standard penetration tests. The samples will be placed in sealed bags and delivered to our laboratory. The borings will be drilled dry and the depth at which groundwater is encountered (if any) will be recorded. The boreholes will be grouted after the completion of drilling and sampling. We will install one (1) 25 feet deep piezometer at preselected boring after sampling borings to measure 24-hr, 15-days & 30-days water level readings. The piezometer will be removed and plugged with cement and bentonite slurry after the 30-day water level reading is performed. Laboratory Testing In the laboratory, each sample will be inspected and classified by a qualified engineer. Laboratory tests will be performed in general accordance with the corresponding ASTM standards and will classify soils and define design geotechnical parameters for the construction of proposed drainage and outfall recommendation, waterline replacement, and pavement recommendations within the Brookglen Subdivision. Laboratory tests will vary with the soils encountered but will be planned to classify soils and define them. All tests will be performed in accordance with the American Society of Testing Materials (ASTM) Procedures. All soil samples obtained will be retained for 3 months after the completion of the final report. Engineering Analyses and Reporting The field and laboratory data will be summarized in an engineering report. Analyses of these data will be presented, and recommendations made in accordance with the HCED Subdivision Regulations and HCFCD regulations for outfall structures into the Willow Springs Bayou. Recommendations will be made relative to the following: Summary of the field and laboratory findings Existing site conditions \\Atl-server\geo\Proposal\2022\GP22-0501 - Brookglen Subdivision - La Porte\GP22-0501 - Brookglen Subdivison - Rev2.doc
