Walla Walla Design Build MATOC 2023 - 2028

The U.S. Army Corps of Engineers established a Master IDIQ for design-build repair, maintenance, new construction, and renovation of large civil works projects with an ordering period that closes April 30, 2028, leaving approximately 21 months of remaining authority. The vehicle carries a $99.9 million shared ceiling across up to five prime contractors with no set-aside restriction, though individual task orders may be designated for small business.

The vehicle was awarded May 1, 2023, to five primes. Ordering activity peaked at nine task orders in 2023, declined to seven in 2024, and has slowed to four through September 2025, a trend suggesting either maturing demand or saturation of near-term workload. The combined potential value across 20 awarded task orders stands at $26.6 million, with $25.4 million (95% of potential) obligated, indicating the vehicle is heavily utilized relative to its current award ceiling and likely constrained by committed capacity.

Work spans the Walla Walla, Portland, Seattle, Kansas, and Omaha districts covering hydroelectric dams, flood-control facilities, navigation locks, levees, and ancillary infrastructure. Recent awards include McNary Lock Elevator No. 2 replacement ($4.117 million), DNFH electrical distribution building construction ($5.427 million), and levee and boat-ramp repairs ranging from $1.2 million to $2.2 million per order. Task orders are firm-fixed-price, typically 12 to 24 months in duration.

Northbank Civil And Marine, LLC dominates with seven orders valued at $14.4 million combined potential, representing 54% of vehicle activity. Macnak Construction LLC holds five orders worth $6.6 million (25%). Advanced American Construction, Inc., Central Environmental Inc., and LOS Alamos Technical Associates, Inc. split the remainder. Ordering is highly concentrated within the Army Corps of Engineers itself (17 orders, $21 million), with minimal secondary Army funding (2 orders, $5.3 million).

Seventy-five percent of awarded task orders carry no set-aside designation; 25% are total small business awards. The vehicle's ordering authority remains open but ordering velocity has declined sharply in the past nine months, suggesting either pipeline exhaustion or a shift toward larger, less-frequent orders under the shared ceiling constraint.

This requirement is for repair and maintenance of real property and construction services to included new construction and renovation to large civil works projects including flood control and hydroelectric dams, river navigation facilities, maintenance and office facilities, roadways and recreational facilities, and river levees. Specific work may include a combination of design, construction and/or repair within Walla Walla District (NWW), Portland (NWP) District, Seattle District (NWS), Kansas District (NWK), and Omaha District (NWO) project sites.
