Salt Waste Processing Facility, Savannah, Georgia
GeoTesting Express, Inc. (GTX) performed comprehensive geotechnical investigation in support of the final design of the Salt Waste Processing Facility at the Savannah River Nuclear Facility. GTX's role was to perform laboratory testing on all of the undisturbed Shelby tube samples for the project. GTX's ability to store, process and test over 340 undisturbed Shelby tubes in an accelerated schedule was a major factor in our selection.
Camp Lejeune Range Training and Lands Program Facility, North Carolina
GeoTesting Express (GTX) provided geotechnical and subsurface exploration services for modifications at various locations on Camp Lejeune Range Training Facility including the existing K-Range facilities, a multi-purpose machine gun range, an engineering training area and explosive ordnance disposal site, infantry platoon battle course, and a borrow area. The field exploration program consisted of soil test borings (mud rotory, piezocone soundings, shear wave velocity tests, and shallow hand excavations.
Central Artery/Tunnel Deep Soil Mixing, Boston, Massachusetts
GeoTesting Express (GTX) made recommendations to the design team advising them on the use of soil mix technology for section of tunnel to be placed in very soft ground. GTX provided a survey of Japanese practice and its applicability to Boston marine clay. GTX performed a large mix design study to show that site soils (clays and organic silts) could be effectively improved with deep soil mixing resulting in the largest deep soil mixing project in the United States at the time - 650,000 CY.
Quarry Hills Recreational Complex, Milton and Quincy, Massachusetts
GeoTesting Express (GTX) provided physical properties laboratory testing on all materials imported to the project site for various components of the landfill cap including low permeability soil, loam, and subgrade. GTX performed over 420 permeability, 60 triaxial tests, 530 grain size analyses, 425 Atterberg limits and 180 moisture-density tests over the duration of the project.
