Brazos Island Harbor contract W912HY24C0008 links a full federal commercial ledger to named field plant. Great Lakes received an initial USD 8.799 million firm-fixed-price award, Padre Island and two survey vessels entered the published October-November operating window, and beach-compatible material moved through 3,550 feet of submerged line to South Padre Island. The April 2025 final-quantity adjustment then deobligated USD 1.343 million, leaving USD 7.456 million currently reported.

Named plant closes the award-to-field gap

USAspending controls the award and transaction ledger, competition fields, contract period and zero reported subawards. Great Lakes controls the maintenance, beneficial-use and original fourth-quarter schedule statements. Coast Guard notices control the named field plant, 24-hour operation, submerged-line length and beach destination. The current USACE survey register is not a contract-specific acceptance record, and the support-vessel notice does not establish a subcontractor.

The deobligation is a measured commercial signal

The USD 1.343 million reduction confirms that final contract quantities materially changed the commercial account. The federal transaction description does not disclose the original or final cubic yards, unit rates, accepted beach volume or payment status. Supplier intelligence therefore has to stop at the public ledger rather than manufacture a productivity or margin explanation.

Evidence conclusion

Owner acceptance remains unpublished

The contract opened at USD 8,798,900. USACE issued notice to proceed on 21 October 2024 and changed DMPA station limits the next day. Padre Island, East River and Laguna appear in the published 20 October-16 November field window. A USD 1,342,725.65 final-quantity deobligation followed on 23 April 2025, leaving a current obligation of USD 7,456,174.35. The operating window and final-quantity modification are strong closeout indicators, but neither publishes the owner's completion certificate, final measured quantity, accepted beach profile or contract-closeout record.

Outstanding evidence
