- Marine interfaces
- Mechanical dredging and scow transport in Connecticut's busiest port, hard-rock removal, shallow access to local placement sites, Cross Sound Cable coordination, active terminal traffic, seasonal environmental windows and multibeam acceptance surveys
- Commercial evidence boundary
- The lowest submitted total, USD 69,469,200 from Great Lakes, is USD 5,827,149.37 or 9.2% above the USD 63,642,050.63 government estimate.

The construction phase was formally launched and the owner set a fall 2026 to spring 2028 expectation, without naming a works contractor.
SourceIndustry Day exposed the delivery and placement constraints
USACE set out the channel geometry, seasonal windows, material classes, placement routes, rock and survey requirements while retaining quantity change risk after maintenance dredging.
