Dunkirk Harbor west breakwater rehabilitation
USACE Buffalo District is repairing Dunkirk Harbor's west breakwater with stone reinforcement and a higher crest. Official federal award data identifies Great Lakes Dock & Materials for both phases: phase one now carries USD 9.156 million of obligations, while the 450-foot phase-two delivery order was signed for USD 1.936 million. USACE reports field work through November 2026; owner acceptance and any lower-tier delivery chain remain unpublished.

Project anatomy
Contract scope and delivery roles
- Client / authority
- U.S. Army Corps of Engineers, Buffalo District
- Delivery parties
- Great Lakes Dock & Materials, LLC (phase-one delivery order W912P424F0022 and phase-two delivery order W912P426FA007)
- Contract route
- Fully federally funded phased rehabilitation ordered under USACE multiple-award IDIQ W912P423D0003. Phase two is firm-fixed-price delivery order W912P426FA007, signed 5 March 2026 after a competitive small-business fair-opportunity process that USAspending records with one offer. The database reports no subcontracting plan requirement and zero reported subawards, which is not evidence that no lower-tier suppliers are involved.
- Execution window
- The phase-one award record runs from 13 June 2024 and carries a potential end date of 31 July 2026; USACE reported it nearing completion on 30 June. Phase two runs from 20 March to 14 October 2026 in USAspending, while USACE's public field target extends through November 2026.
- Works package
- USACE reports approximately 1,850 feet repaired in phase one and another 450 feet in phase two, using stone reinforcement and a raised crest. Its attached map labels the outer breakwater as 2,812 linear feet and marks a separate reach outside the current scope. The 2024 announcement described approximately 1,450 feet of lake-side overlay plus an east-head wrap; the award summary does not itemize the later scope and obligation changes.
- Marine interfaces
- Armourstone handling and placement on an exposed Lake Erie breakwater beside an operating federal harbor entrance, with work-platform access, crest elevation changes and navigation separation around the marine plant
- Commercial evidence boundary
- The federal award record resolves the second-phase contractor and amount: Great Lakes Dock & Materials, USD 1,936,019.80, signed 5 March 2026. That supports USACE's rounded USD 1.9 million narrative and leaves the USD 4.5 million bullet unsupported. Phase-one obligations now total USD 9,155,616.59 versus the USD 7.56 million initial announcement; the award summary does not identify which scope, quantity or time modifications produced the difference.

The district says approximately 1,850 feet are nearing completion and the last 450 feet will run through November 2026. Its USD 1.9 million narrative aligns with the signed federal award; the USD 4.5 million bullet remains unsupported.

Buffalo District video shows marine plant and a long-reach material handler working on the Dunkirk breakwater. It confirms construction activity in August 2025 but does not establish production quantities, accepted length or the later second-phase start.
SourceUSACE awarded the original repair contract
The initial USD 7.56 million Great Lakes Dock & Materials award covered approximately 1,450 feet of lake-side stone overlay and an east-head wrap. USAspending now records USD 9,155,616.59 of obligations on W912P424F0022, but the reviewed summary does not itemize the increase.
SourceEvidence gap
What remains unverified
Outstanding evidence
- Inspection and acceptance of the approximately 1,850-foot first phase
- Owner correction or withdrawal of the unsupported USD 4.5 million phase-two bullet
- Modification detail behind phase one's move from the USD 7.56 million initial announcement to USD 9.156 million of current obligations
- Stone delivery, placement and crest-raising progress by repair reach
- Navigation controls around marine plant and the harbor entrance
- Completion, survey and acceptance evidence against the 14 October contract date and November 2026 owner target
- Any reported subaward or major supplier; USAspending currently reports zero subawards but does not prove that no lower-tier work exists
- Treatment of the phase-map reach marked outside the current repair scope
