News and Events
Three new professionals have joined the geotechnical group at GER.
topScott Barnhill with over 40 years experience in geotechnical and environmental engineering has recently attained life time status in the American Society of Civil Engineers and became a Board Certified Geotechnical Engineer in the Academy of Geoprofessionals. Mr. Barnhill has held key technical and managerial positions in the areas of environmental and geotechnical engineering. He was an adjunct professor of engineering at Old Dominion University teaching foundation engineering for 11 years. He has been involved in over 6000 projects nationally and overseas, but predominantly located on the east coast from Maine to Florida. Projects have included DOD projects, such as the Pentagon Basement Renovation, commercial buildings, large industrial and waterfront facilities, coal terminals, landfills, roadways, bridges, slope stability, underwater slopes, bulkhead design, underwater retaining walls, foundations, soft soil response, ground reinforcement, and ground improvement.
topWe recently completed geotechnical services for P737 ECP, NAS II Sigonella in Sicily. The study indluded tradtional SPT soil borings, laboratory testing and geophysical work.
topScott A. Barnhill, P.E. attains Fellow status at ASCE
Scott Barnhill with over 37 years experience in geotechnical and environmental engineering has recently attained Fellow status in the American Society of Civil Engineers. Mr. Barnhill has held key technical and managerial positions in the areas of environmental and geotechnical engineering. He is an adjunct professor of engineering at Old Dominion University teaching foundation engineering. He has been involved in over 8000 projects nationally and overseas, but predominantly located on the east coast from Maine to Florida. Projects have included DOD projects, such as the Pentagon Basement Renovation, commercial buildings, large industrial and waterfront facilities, coal terminals, landfills, roadways, bridges, slope stability, underwater slopes, bulkhead design, underwater retaining walls, foundations, soft soil response, ground reinforcement, and ground improvement.
topCrystal Cox has written a new paper called "Constitutive Model Input Parameters for Numerical Analyses of Geotechnical Problems: An In-Situ Testing Case Study" to be published in Proceedings of the Sixth International Symposium on Deformation Characteristics of Geomaterials in Buenos Aires. Numerical modeling and finite element analyses are increasingly becoming cost effective methods for assessing geotechnical problems. The use of in-situ testing methods, notably the SDMT, along with stiffness reduction approaches utilizing G-γ curves are used to obtain stiffness related input parameters for numerical modeling. This paper presents the steps used to obtain stiffness parameters based on shear wave velocity measurements taken from SCPTu and DMT data and presents a case study of a monitored embankment.
topCrystal Cox has written a paper in concert with Dr. Paul Mayne of Georgia Tech for DMT-15 concerning "Soil stiffness constitutive model parameters for geotechnical problems:A dilatometer testing approach".
top12 MW Photovoltaic System NS Guantanamo Bay, Cuba
This is a geotechnical study for a new photovoltaic system at Naval Station Guantanamo Bay, Cuba. The project included the drilling of 36 soil test borings, laboratory testing and foundation design for the project.
topChabelley Air Base, Djibouti, Africa
The project combines both geotechnical and surveying services for the rehabilitation of the airfield.
topGER has been awarded a new project in Rota, Spain.
topCrystal Cox and Scott Barnhill attended CPT-14 in Las Vegas this May. Their paper titled " Axial pile capacity within an elastic continuum framework in Virginia’s Coastal Plain" was published in the proceedings.
