SUBSURFACE INVESTIGATION, SECTION B006E, SILVER SPRING STATION, GLENMONT ROUTE

Results are presented of six tests boring made at the locations of pier foundations for Colesville Road Bridge and the Silver Spring Station structure in Section B006e at the intersection of Colesville Road and Glenmont Route in northwest Washington, D.C., of the Washington Metropolitan Area Metro System. The purpose of the work was to evaluate subsurface conditions at the locations of a group of pier foundations to determine the need for pile support or the suitability of spread footings. The report contains logs of the test boring, results of laboratory strength test on 2-inch Shelbytube samples, geological sections along the lines of the bridge piers and comments regarding foundation conditions.
