The University of Southern Mississippi is seeking a contractor to augment multiple oyster reef plots within one-acre areas using surficial enhancements of #57 limestone gravel. The project involves four 50-acre site areas, with two sites in western MS Sound and two in eastern MS Sound. The contractor will be required to apply 100 cubic yards of #57 limestone gravel per reef plot, with even dispersion across the reef-plot areas. The project requires adherence to timing and precision of gravel applications, and the contractor must immediately notify the USM project manager of any anticipated deviation from the specified times and placements of gravel application. • The project involves four 50-acre site areas, with two sites in western MS Sound and two in eastern MS Sound. • The contractor will be required to apply 100 cubic yards of #57 limestone gravel per reef plot. • The project requires adherence to timing and precision of gravel applications. • The contractor must immediately notify the USM project manager of any anticipated deviation from the specified times and placements of gravel application. • A quality control procedure involving side-scan sonar imagery before and after the application period will ensure specifications were followed.
