About this vehicle
The Department of the Army Corps of Engineers established this Master IDIQ for stoplog slot cut conversions on the McClellan-Kerr Arkansas River Navigation System (MKARNS), with ordering authority extending through February 11, 2029—approximately 2.5 years of remaining ordering window. The vehicle carries a $200 million shared ceiling and has issued 9 task orders totaling $118.7 million in combined potential value, of which $116.2 million (98%) is obligated. All awards are unrestricted, with no set-aside designations applied.
Work consists of concrete demolition, dive work, steel fabrication, and above-and below-water concrete placement to install stoplog recesses and sill modifications at lock and dam facilities. Task orders completed to date address bulkhead conversions at Murray, Toad Suck, Ormond, Ozark Jetta-Taylor, James W. Trimble, and Dardanelle locks, with typical durations spanning 365 to 900 calendar days.
The awardee base is concentrated among three heavy construction firms. Alberici Constructors Inc. leads with two orders worth $69.8 million in combined potential value, followed by McMillen, Inc. with $34 million across two orders and Occi Inc. with $14.9 million. The remaining two awardees—Massman Construction Co. and Johnson Bros Corp., A Southland Company—hold minimum-guarantee task orders valued at $10 thousand each. These three firms capture 100% of the combined potential value.
Ordering activity shows a sharp decline: seven task orders awarded in 2024, then one in 2025 and one in 2026. The Department of the Army Corps of Engineers Engineering District Little Rock has placed 5 orders valued at $101.9 million, while the parent Department of the Army Corps of Engineers placed 4 orders valued at $16.8 million. The largest single award to date is the January 2026 delivery order to Alberici for bulkhead work at Locks 7, 8, and 9, valued at $69.8 million with a January 2027 expected completion. All task orders are firm-fixed-price deliveries with no recurring ordering pattern.
Description
in this IDIQ each conversion will be unique, but they will all have similar construction activities and typical repair activities. Each conversion will consist of concrete demolition, dive work, steel fabrication, and both above and below water concrete placement to accomplish sill modification and stoplog recess installation.
