SCORE 56 17 New York Ave Nw, Washington, Dc 20006 We will perform a total of two soil borings on the site. Each of the borings will be advanced to a depth of feet below existing site grades, and will be located within the bounds of the private property. The borings will be drilled utilizing 3. 25-inch hollow stem, continuous flight augers. The borings will be performed utilizing an atv-mounted drill rig and will generate an approximate 6-inch annulus. After geotechnical exploration is completed, the borings will be backfilled with bentonite slurry, which has a consistency of two pounds bentonite powder to one gallon water. Borehole abandonment will be performed by tremie-grouting via a positive-displacement pump from the bottom of the borehole.
