Gsi plans to drill 5 soil test borings to confirm soil strength with a hollow-stem auger equipped with a split spoon sampler for the spt n-value tests down to a maximum depth of to 1 feet below existing grades. All borings will be drilled to the maximum depth or auger refusal whichever occurs first. The boreholes dimension will be 3. 25 inches and shall be grouted upon completion. See attached work plan.

Using hollow stem auger method, we will drill three 6 inch diameter test borings. The borings will be drilled to a depth of feet. In the unconsolidated zone we will use outer casing to prevent ground water contamination. All the spoils will be containerized in 55-gallon drums and sent for disposal upon review of chemical results. The bore holes will be grouted with a 60: ratio of bentonite powder to cement for paved area, and grouted with 2 pounds of bentonite powder to 1 gallon of water for the borings that are located in non-paved areas.
