McLaren Engineering Group holds an on-call contract to provide marine and geotechnical engineering along with permitting, underwater and site inspections, and emergency response services for the New York City Department of Corrections (NYCDOC) marine structures.
The northern shorelines of Rikers Island and Hart Island sustained considerable damage from Superstorm Sandy. As part of our on-call services McLaren provided damage assessment, support for FEMA applications, and prepared construction documents and construction management services for the restoration and mitigation of 11,750 feet of combined shoreline. Some of the work included riprap slope protection, marine structure repair, raising flooded roadway, and shotcreting 1,500 feet of eroding sand cliff.
The Vernon C. Bain Center (VCBC) prison barge is one of the world’s largest prison barges in operation. During Superstorm Sandy the mooring arms restraining the VCBC barge experienced their maximum range of motion. McLaren was called in to provide emergency response services inspecting the structures for damage and performing an analysis of the arms capacities to withstand future storms. Additional work at VCBC has included developing new future storm design criteria and modifications to increase the barges safe range of motion, improved design of floor resurfacing for enhanced safety and plumbing upgrades, and conducting a relocation feasibility analysis.
