Geotechnical Field Exploration and Laboratory Testing

The U.S. Army Corps of Engineers established a Master IDIQ for geotechnical field exploration and laboratory testing on February 11, 2021, with a combined potential value of $20 million across four prime contractors. Ordering closed on February 10, 2026—the vehicle is no longer accepting new task orders.

Scope covers field exploration, core drilling, soil sampling, and laboratory testing to characterize subsurface material across the Southwestern Division. Work sites range from hard-surfaced dry land to soft marshlands, swamps, dredged material placement areas, partially to fully submerged areas with standing water, and densely vegetated terrain. Projects also extend to inland waterways and channels, rivers, lakes, bays, streams, and offshore waters from Texas, Louisiana, and other states as required by individual task orders.

The vehicle was structured as a multiple-award IDIQ with two unrestricted and two small-business reserve slots, though all 15 awarded task orders carry no set-aside designation. All task orders are firm-fixed-price delivery orders. Eustis Engineering, L.L.C. dominates by order count with six awards totaling $3.2 million combined potential value, followed by Professional Service Industries, Inc. (four orders, $1.3 million), Qri-Tetra TECH JV (three orders, $1.3 million), and Fugro USA Land, Inc. (two orders, $2 million).

Ordering activity concentrated in 2021 (six orders) and has declined steadily: three orders in 2022, three in 2023, two in 2025, and one in 2026. The vehicle obligated $7.7 million of the $7.8 million combined potential value across all task orders—a 98% execution rate. The most recent award issued February 25, 2026, was a $515,727 delivery order to an unnamed contractor for geotechnical services at Willow Bayou Marsh Restoration in Cameron Parish, Louisiana, due September 3, 2026.

The Department of the Army Corps of Engineers placed 12 orders ($3.3 million combined potential value), with the remaining activity split between the Department of the Army (two orders, $2.6 million) and the Galveston Engineering District (one order, $2 million). Task-order values ranged from minimum guarantees of $2,500 to a ceiling of $2.04 million, with most substantial orders targeting placement areas and navigation channels in the Houston Ship Channel, Galveston Bay, and Gulf Coast waterways.

Field exploration, core drilling, soil sampling and laboratory testing services to determine the type, nature, and characteristics of the subsurface material at existing and proposed project sites. Locations will include terrain of varying types, steepness, and consistencies ranging from hard-surfaced dry land to soft marsh lands, including swamps and dredged material placement areas, lands with excessive moisture or soft to very soft surface and subsurface conditions, partially to fully submerged areas with varying depths of ponded or standing water, and areas which may be covered by heavy vegetation or brush. Locations may include inland waterways and channels, portions of other bodies of water, and waters of and in close proximity of deep draft navigation channels including entrance channels offshore. The locations of the projects will at times be on islands that are only accessible by water. Locations will also include shallow and deep draft inland waterways and channels, rivers, lakes, bays, streams, and similar bodies of water within the Southwestern Division, as well as waters offshore from the States of Texas and Louisiana and other states and counties as required by specific task orders.
