Results are summarized of thirteen supplementary borings made at the location of sewer crossings on M street in southeast Washington, District of Columbia and at selected locations within the Washington Naval Shipyard. The borings were performed to investigate conditions at the planned crossing of the subway tunnels beneath the M Street sewers and to ascertain the character of deep bearing strata for high-load underpinning piles to be installed within the Navy Yard. The report contains geological sections incorporating the new borings, logs of these borings, results of laboratory tests on soil samples obtained and a discussion of anticipated design and construction problems. This investigation is for the Washington Area Metro System.
