The Coastal Protection and Restoration Authority (CPRA), in collaboration with the Water Institute of the Gulf, awarded the University of New Orleans research team, led by principal investigator Professor Malay Ghose Hajra PhD, PE, with a CPRA Applied Research Program grant. Eustis Engineering Services, L.L.C. has been selected to provide geotechnical exploration, soil mechanics laboratory testing, and peer review services for the project.
The funded project, titled "Evaluation of the Effect of Soil Sample/Specimen Size on Undrained Shear Strengths in Soft Soils for Coastal Protection and Restoration Projects," is a one-year study that seeks to examine the effects of sample/specimen size on shear strengths and consolidation properties. The research team will explore three coastal sites using soil borings and in situ testing techniques, cone penetration tests, and vane shear tests.
Eustis Engineering drill crews and laboratory technicians will perform soil borings, soil mechanics laboratory testing, and vane shear testing. Studies of the different sampling and testing methodologies used to properly characterize the coastal soil will assist in the future design of coastal protection and restoration projects.
"Our drilling and laboratory testing departments have built and upheld a reputation of providing safe, professional, and high quality services on a timely basis. We are proud that our remarkable crew members, laboratory technicians, and engineers have been recognized for their ability to deliver superior work and are honored to be selected to provide services for this major research project that will benefit the Louisiana coast," said Eustis Engineering's President, William W. Gwyn, P.E.
The CPRA Applied Research Program began in 2013 and was able to award $250,000 in funding this year. The program received 19 research submissions totaling $1.8 million in proposals. Only three of the 19 submissions were selected to receive funding.
