Miami Harbor Construction Dredging Project
Tetra Tech is helping PortMiami prepare to service larger cargo ships after the Panama Canal’s expansion is completed in 2015. We are supporting the widening and deepening of the harbor’s entrance channel and interior port, providing environmental services and mitigation construction.
Tetra Tech, as a subcontractor of Great Lakes Dredge & Dock Company, is responsible for $24.4 million in environmental services and mitigation construction work associated with the $206 million widening and deepening project at PortMiami. This is the first project in the Southeastern United States to prepare for receiving larger, post-Panamax cargo ships when the Panama Canal’s expansion is completed.
For the first time, the U.S. Army Corps of Engineers has awarded a contract that holds the dredging contractor accountable for the project’s environmental management, comprehensive monitoring, and quality control. Tetra Tech is supporting this complex project’s requirement to protect sensitive hardbottom, coral, seagrass habitat, water quality, and listed species in and around the dredging area.
Tetra Tech is performing comprehensive environmental management and reporting and coordinating environmental-related activities with responsible agencies. Our experts are overseeing the environmental monitoring program and the quality control of coral and seagrass harvesting, transplanting, and monitoring activities. Tetra Tech’s team is also responsible for constructing 9.28 acres of low-relief (<3 ft) and high-relief (>3 ft) artificial reefs offshore using approximately 50,000 tons of quarried limestone boulders, and placing 55,000 cubic yards of select fill to support 16.6 acres of seagrass restoration in a dredge hole north of the Julia Tuttle Causeway within the Biscayne Bay Aquatic Preserve.
