SCORE 56 30 K St Nw, Washington, Dc 20007 We will perform a total of 4 soil borings on the proposed site to a depth of feet below existing grades. The borings will be located within the bounds of private property. The borings will be drilled utilizing a 4. 25-inch hollow stem, continuous flight auger and/or mud rotary drilling. The borings will be performed using a truck-mounted drill rig and will generate an approximate 6 inch annulus. After geotechnical exploration is completed, the boring will be backfilled with bentonite slurry, which has a consistency of two pounds bentonite powder to one gallon of water. Borehole/auger probe abandonment will be performed by tremie-grouting via a positive displacement pump from the bottom of the borehole/auger probe.
