Two 2 geotechnical soil test borings will be drilled around the north side of the existing building. Borings will be extended to an average depth of feet below the existing ground level using hollow stem auger drilling methods creating an approximately 6" diameter boring. Spoils generated will be containerized in drums and once completed borings will grouted in accordance with ddoe permit.

A total of two 2 soil test boring will be drilled at the above referenced site at the front of the existing building. The boring will be drilled using 3. 25-inch continuous flight augers. The boring will extend to a maximum depth of feet below current site grades. The boring will be drilled using a truck- or atv-mounted drill rig. We anticipate that the maximum annular diameter of the hole from the field exploration including the auger flights will be about 6-inches. The soil sampling interval will be every 2. 5 feet within the upper feet of the boring, followed by every 5 feet to the maximum depth explored. The samples will be containerized in glass jars for geotechnical classification and laboratory testing. To prevent contamination of the boring between soil strata, the drilling rods will be decontaminated using a steam cleaner or an alconox solution prior to commencing drilling of each boring.

Tow 6-inch diameter soil test borings will be drilled where the existing buildings have been razed. The borings will extended to a depth of feet below the existing ground level. If rock is encountered, the rock will be cored up to feet using nq sized coring with an annular diameter of 3. 25-inch. Spoils generated will be containerized in drums and grouted using 2lbs bentonite to 1 gallon of water in accordance with ddoe permit.
