The drilling subcontractor was Vironex, Inc., of Bowie, Maryland. The soil borings were drilled by the direct push technology (DPT, or “Geoprobe”) drilling methodology. With the DPT technique, a sampling barrel fitted with a 2-inch-diameter by 4-foot-long acetate core sleeve is hydraulically advanced (or pushed) into the subsurface to obtain a soil core. The barrel is withdrawn from the borehole, the acetate core sleeve is removed, a new core sleeve is inserted into the barrel, and also the sampling assembly is reinserted into the borehole to obtain ensuing core. The borehole stayed open when the sampling assembly was withdrawn as a result of the clayey and silty nature of the soil. At every location, continuous soil samples or cores were collected from the bottom surface to the highest of bedrock (which was outlined as hydraulic refusal, or the lack to additional advance the barrel). The depths of the 2 borings were ten feet (01SB51) and 11 feet (01SB52). At the conclusion of every boring, the borehole was backfilled with a mixture of soil cuttings and bentonite. The [http://www.denichsoiltest.com/tag/soil-boring soil boring test] were surveyed for horizontal location and vertical elevation by James M. Stewart, Inc. Their survey information are presented in Appendix A.
