Sabine-Neches Contract 6 is a separately traceable federal hopper-dredging package, not shorthand for the full waterway programme. Great Lakes holds USD 219.108 million in current obligations against a USD 235.423 million potential total with all options. USACE measured the bid baseline at approximately 41 miles and 35.8 million cubic yards, while the public federal record names no subaward recipient despite an individual subcontracting plan.

Current surveys extend the delivery evidence chain

USAspending controls award structure, competition, values, dates, the individual subcontracting-plan field and zero reported subaward actions. USACE controls the measurable 41-mile and 35.8-million-cubic-yard scope and current survey register. Great Lakes controls its rounded value and original forecast, while SNND controls the later package sequence and April 2027 owner schedule. Lower-tier firms, Contract 6 fleet assignments, accepted production and final value remain unpublished.

The contract has four commercial snapshots

A single rounded contract value hides the difference between obligated work, exercised options, open options and later agency snapshots. The same boundary matters for supplier intelligence: an individual subcontracting plan signals a managed lower-tier route, but a zero subaward count reveals only what USAspending currently reports. Dredge operators, surveyors, disposal providers and support firms cannot be named without stronger records.

Evidence conclusion

Production and acceptance remain the next gates

The defensible commercial ledger is USD 219,108,350 in current obligations and base plus exercised options, USD 235,422,810 including all options, USD 235,245,750 in the August 2025 USACE briefing and approximately USD 235 million in Great Lakes reporting. Those figures are close but not interchangeable. Contract 6 also remains distinct from the USD 239 million Callan package and later Contracts 7 through 9. The next step is contract-specific field evidence: assigned hopper plant, dated production, modifications, accepted quantities, disposal records, subaward reporting and hydrographic acceptance by reach.

Outstanding evidence

  • Current obligation and option-exercise changes
  • Contract-specific hopper-dredge and support-fleet assignments
  • Reported subawards and named lower-tier work packages
  • Production against the 6.9-million-cubic-yard shoal and 28.9-million-cubic-yard new-work split
  • Placement-area or ocean-disposal records
  • Reach-level post-dredge surveys and accepted geometry
  • April 2027 completion and navigation release
  • Certified final account
