USACE scheduled Morrish-Wallace's 109,000-cubic-yard campaign to start on 6 October 2026 and finish by 1 November; actual mobilisation remains unverified

Project sources

Buffalo District scheduled Morrish-Wallace Construction Co. to start Sandusky Harbor maintenance dredging on 6 October 2026 under a USD 628,000 contract. The mechanical campaign covers approximately 109,000 cubic yards from the Moseley and Straight federal channels. USACE expects 100,000 cubic yards to go to a nearshore placement site, where currents can redistribute sediment along the coast, and 9,000 cubic yards to a designated open-lake site. The public release schedules completion by 1 November but does not verify actual mobilisation or report measured production, post-dredge depths or acceptance.

Contract scope and delivery roles

Client / authority
U.S. Army Corps of Engineers, Buffalo District
Delivery parties
Morrish-Wallace Construction Co.
Contract route
USACE reports a USD 628,000 contract awarded to Morrish-Wallace Construction Co. in July 2026. The reviewed release does not disclose the contract number, competition method, bid count, obligation history, options, modifications or final account.
Execution window
USACE scheduled the operation to start on 6 October 2026 and finish by 1 November. Those dates define the planned field window, not verified start logs, uninterrupted production, demobilisation or owner acceptance.
Works package
Mechanical dredging of approximately 109,000 cubic yards from the Moseley and Straight federal navigation channels. The planned material route assigns 100,000 cubic yards to nearshore placement for littoral redistribution and 9,000 cubic yards to a designated open-lake site.
Marine interfaces
The campaign links channel access, mechanical excavation, scow or barge handling, open-lake placement and nearshore nourishment. Plant movements must coexist with commercial and recreational navigation. Sediment suitability, placement coordinates, weather, currents and post-dredge hydrography control whether the announced quantity becomes accepted channel and coastal performance.
Commercial evidence boundary
The USD 628,000 figure is the reported current contract value. It should not be combined with Sandusky's separate 2025 campaign or earlier hydraulic dredging and wetland-placement contracts. The 109,000-cubic-yard figure is planned scope, not a certified pay quantity or unit-rate basis.

Evidence gap

What remains unverified

Outstanding evidence

  • Named mechanical dredge, scows, tugs and operating sequence
  • Daily and cumulative production from the Moseley and Straight channels
  • Nearshore and open-lake placement receipts against the 100,000 and 9,000-cubic-yard plan
  • Post-dredge hydrography against authorized channel depths
  • Completion, acceptance and final contract value after the 1 November target
