About this file
This is a soil boring report prepared by Siefert Associates, LLC for the Connecticut Army National Guard Camp Simulator Building project located in Niantic, Connecticut. The report documents geotechnical investigation work performed on May 15, 2017, by General Borings Inc. at four boring locations (B-1, B-2, B-3, and B-4) around the proposed simulator building site. Each boring was drilled to a depth of 27.0 feet using a Diedrich D-50 auger with automatic casing and standard split-spoon samplers. The borings were conducted with a 140-pound hammer and 30-inch automatic drop system, with sampling performed at regular intervals throughout the depth of each hole. The exploration locations were determined through taping and visual estimates from existing site features and should be considered accurate only to the degree implied by the survey method used.
The subsurface conditions at all four boring locations consist primarily of fill material and natural sand deposits extending to the total boring depths. Soil compositions vary slightly between locations but generally include loose to medium dense sand with varying grain sizes (fine to coarse), trace to some gravel content, and trace to some silt. Surface elevations range from 20.0 to 21.0 feet across the boring locations. No groundwater was encountered during the initial drilling phase at any of the four boring locations, though B-3 showed groundwater observations recorded at 20.5 feet after one hour. The boring logs provide detailed field identification data, blow counts from the standard penetration testing, sample recovery information, and descriptive remarks regarding soil color, composition, and characteristics at each depth interval, establishing baseline geotechnical conditions for design of the proposed simulator building foundation and construction planning.
