Performance Proppants plans on constructing a plant at the Port of Caddo-Bossier, approximately 4 miles south of the city limits of the City of Shreveport to process the sand that will be dredged from the Oxbow of the Red River. The plant will be constructed on the unprotected side of the levee system. Performance plans to dredge sand from the Oxbow using a cutter head dredge and hydraulically transport the slurry (sand, gravel, and fines) across the Red River through underground pipes that will be installed using horizontal directional drilling (HDD) methods.
AME was authorized to provide geotechnical services for the project in two phases. Phase I included the drilling, sampling, and laboratory testing to characterize the material to be dredged out of Oxbow Lake. AME performed a specific grain size analysis to identify the specific material required for this project.
Phase II of the project included drilling, sampling, laboratory testing, and analyses for the evaluation of the stability of the Red River levee during dredging activities and the proposed plant facility. Field exploration for Phase II included soil borings within 2,000 feet of the levee for which a Letter of No Objection (LONO) from the Bossier Parish and USACE Vicksburg District was required. Phase II also included completing additional borings in the Oxbow to further characterize the material to be dredged.
AME performed this work as a sub-consultant to Providence Engineering and Environmental Group.
