This very complex and challenging dredging project in the southern branch of the Elizabeth River in Portsmouth, VA, has been completed. Over 325,000 cubic yards of sediment in varying levels of contamination have been dredged and amended. Dredging under, inside, and around naval piers and the new South Jordan Bridge, requiring complex and close tolerance elevations, was successful. The project is moving into the final stages of capping clays and soft sediments to provide habitat for the resurgent benthic community.
Dredging, the placement of over 300,000 cubic yards of sand fill, and the setting of thousands of tons of rock revetment have been completed at the former Maryland Dry Dock Wet Basin at the Masonville Marine Terminal. Stages one and two out of three are complete at the former Fruit Pier at South Locust Point Marine Terminal. The crew is finalizing storm water management infrastructure while the settlement period passes at South Locust Point. The Project Team attributes the early completion of the project, over sixty days ahead of schedule, to the dedication and hard work of the crews on this project.
This is the 5th contract completed by Corman Marine on Project Oyster Habitat Restoration in the Choptank Water Shed for the US Army Corps of Engineers and the Maryland Department of Natural Resources. CM crews constructed reefs of mixed shell in the Tred Avon River. The reefs are to be seeded with baby oysters as part of the effort to restore oysters to the Chesapeake Bay. The project has been so successful CMC is on standby while the USACE secures additional shell. The USACE and the MDNR expect work to resume in early December.
Corman Marine successfully completed the reconstruction of the fender system protecting the Route 231 Bridge over the Patuxent River. CMC crews worked on the river through the winter driving pile and installing over 100 tons of structural steel in order to complete the project on time.
CMC commenced dredging operations on this fast track Project with a small hydraulic dredge. The dredge encountered numerous and significant differing site conditions (several sunken barges and a potential environmental health issue) which resulted in a stop work order being issued. The job team developed new means and methods to complete the project that would largely eliminate the environmental health issue and enable the team to work around the sunken barges. The new plan was submitted to the owners resulting in a change order and work recommenced. Presently the project is up and running well ahead of schedule. If the team maintains this pace the project will be completed in 75% of the allotted time.
Corman Marine has begun work on a challenging pile driving project – driving pile for the foundation of the new Academic Building for Cyber Security Studies at the US Naval Academy, Annapolis, MD. The project not only has a very fast track, but also has very significant challenges due to the extremely close proximity to the US Naval Academy’s Nimitz Library and Rickover Hall. Limited space in and around the project site required that the piling delivery be supported by the marine group’s tugs and barges, which required the installation of spud wells to protect the Naval Academy waterfront promenade.
