The U.S. Army Corps of Engineers, Kansas City District, is soliciting design-build construction services for the installation of access manholes at the Fairfax-Jersey Creek Levee Unit on the Missouri River in Kansas City, Kansas. The project scope involves designing and constructing manholes, with estimated depths between 10 and 25 feet, to facilitate the video inspection of approximately 27,000 feet of existing perforated corrugated metal seepage collector pipe.

AI Contract Overview

The Willapa Harbor Maintenance Dredging project, led by the US Army Corps of Engineers Seattle District, involves dredging federally authorized navigation channels in Bay Center, Nahcotta, and Tokeland, Washington to maintain safe and navigable depths. Approximately 180,000 cubic yards of material will be removed using mechanical clamshell dredging to achieve depths ranging from -10 to -15 feet MLLW, with an additional overdepth allowance at each site. An additional dredging of up to 10,000 cubic yards may be necessary in the Bay Center/Palix River Access Lane to facilitate transit of dredging vessels, though this volume could vary due to dynamic river conditions. Dredged material will be disposed of at designated open-water sites via bottom dump scow. The operation is scheduled to commence in summer 2026, with specific in-water work windows defined seasonally for each location to minimize environmental impacts and meet regulatory requirements. Navigational challenges in Willapa Bay, including exposure to Pacific Ocean weather, shifting shoals, and removal of navigation aids by the Coast Guard, pose significant safety and operational difficulties for contractors. The project budget is estimated between $5 million and $10 million, with dredging expected to last from three to seven months. Bidders must comply with Federal Acquisition Regulation standards, with solicitation documents available through the Army Corps office in Seattle. Key contacts for the project include Geraldine Kemp and Kimberly M. Robinson, and the solicitation response deadline is set for mid-December 2025.

Full Description

Please see attached Amendment 0003 for complete details. Willapa Harbor Maintenance Dredging project in Willapa Harbor, Washington. USACE, Seattle District has been tasked to solicit for and award a construction contract to maintenance dredge the Bay Center, Nahcotta, and Tokeland Federal Navigation Channels to their authorized depths. Up to 180,000 CY is expected to be dredged across the three features via mechanical clamshell dredging. The minimum required dredging depth varies from -10 ft (Bay Center and Nahcotta) to -15 ft (Tokeland), MLLW, +2 ft overdepth at each location. In addition, dredging approximately 10,000 CY to a minimum depth of -9 ft MLLW (+1 ft overdepth) may be required in the Bay Center/Palix River Access Lane to ensure sufficient water depths for the dredge, scow, and tugboats to transit between Bay Center and the disposal sites. This amount has the potential to change due to the dynamic nature of the Palix River at its confluence with Willapa Bay. Dredged material will be disposed via bottom dump scow at the Cape Shoalwater open-water dispersive disposal site or the South Channel open-water dispersive disposal site. Work is anticipated to begin in summer 2026. The work window varies by project features. For any given calendar year, the in-water work windows are as follows:? Bay Center/Palix River: 16 Jul through 30 Sep? Nahcotta: 16 Jul through 01 Feb? Tokeland: 16 Jul through 15 FebWillapa Bay presents significant navigational hazards due to its exposed Pacific Ocean entrance, unmaintained channels, shifting shoals, and unpredictable weather. This performance window includes the worst season for storm and marine conditions. The U.S. Coast Guard has removed aids-to-navigation at Willapa Bar because of unreliable conditions, and their Waterways Analysis notes over 50 unreported groundings annually. These hazards present serious safety concerns for contractors and local users, complicating mobilization and dredging operations throughout the project area.In accordance with Federal Acquisition Regulation (FAR) Part 36 , the estimated construction price range for this project is: Between $5,000,000 and $10,000,000. Estimated duration of the dredging activities is 3-7 months. PLEASE SEE THE ATTACHED SOLICITATION, SPECIFICATIONS AND DRAWINGS FOR INSTRUCTIONS ON SUBMITTING A BID IN RESPONSE TO THE SOLICITATION.
