• Furnishing and operating critical maritime and heavy equipment assets. The detailed list may include, but will not be limited to the following:
  
  
  
  • 250-ton floating crane with an operator
  
  
  • Material and handling work barges
  
  
  • Note: Work barges must be capable of operating within a navigational channel width of 90 feet (bathymetry data is available)
  
  
  • All-terrain 90-ton crane with an operator (to assist in swinging materials into the barrier house
  
  
  • Vacuum trucks (for debris clean out of the gate’s interior)
  
  
  • Man lifts/telehandlers
  
  
  • Underwater lifting bags
  
  
  • Dewatering pumps
  
  
  • Supplementary rental generators or compressors
  
  
  • Necessary rigging for lifting operations
  
  
  
  


• Providing, operating, and maintaining all necessary confined-space safety equipment, including forced-air pumps and atmospheric monitoring systems, to ensure safe working conditions during all interior barrier operations. Note: Sediment is assumed to be contaminated with specific metal concentrations that exceed Connecticut DEEP direct exposure criteria, including but not limited to Zinc (up to 35,900 mg/kg), Arsenic (up to 15.3 mg/kg), and Cadmium (up to 43.8 mg/kg), along with elevated Benzo(b)fluoranthene (PAHs). Additionally, the assumed presence of Hydrogen Sulfide (H2S) requires positive-pressure supplied air respirators for all entrants.


• Executing a complete debris cleanout of the hurricane barrier's interior gate (approximately 20 tons). Additional site activities include the replacement of structural anodes (approximately 225), and the installation of designated helical anchor points for the deployment of silk turbidity curtains for sediment containment in the work area.
