PROJECT OVERVIEW

The redevelopment of this amalgamation of former Superfund and Brownfield industrial sites along the shores of Hempstead Harbor in Glen Cove, New York involved a multitude of construction work scopes. The work consisted of environmental dredging of 5,000 CY of impacted sediment with onsite stabilization, and barge transportation to disposal facilities. In addition, the scope included material placement of 13,000 tons of environmental capping material, underwater demolition of the deteriorated bulkhead with divers, and barge mounted crane support. Work also included the construction of two marinas (75-slip transient marina and a 22-slip private marina), and a pile supported aluminum fixed bridge walkway.

WHAT MADE THIS JOB COMPLEX

One challenge was the coordination with Local, State, and Federal Authorities. Performing construction while balancing interwoven regulations set by multiple agencies for dredging, marina construction, environmental remediation, site work, and infrastructure improvements made this project quite complex. The completion of the dredging required a USACOE permit modification which was obtained by BWM through field trials and documented performance.

HOW POSILLICO SOLVED IT

BWM partnered with Posillico and took a very proactive approach to the challenges. Weekly meetings were held with the client and project consultants, coordinating directly with the Local, State, and Federal Agencies. We used our experience in filing permits to expedite the approvals and modifications necessary to push the project forward. The project team assisted with the redesign of certain scope items such as the bulkhead and drainage systems to better suit field conditions. Utilizing modern hydrographic survey equipment, we were able to accurately remove the targeted material during dredging to decrease disposal scheduling costs.
