Soil Engineering Testing Inc.

Soil Engineering Testing Inc. provides geotechnical laboratory testing services to the U.S. Army Corps of Engineers as a prime contractor under full-and-open delivery orders and single-award indefinite delivery contracts, competing without set-aside designation despite self-certification as a small disadvantaged business. The Minneapolis-based firm specializes in soil sample analysis using ASTM standards—including water content analysis, particle size distribution, Atterberg limits testing, soil classification, consolidation testing, and hydraulic conductivity measurements—in direct support of the Corps' civil works, infrastructure development, environmental protection, and construction planning programs across the Midwest region.

Soil Engineering Testing Inc. operates entirely as a prime contractor (100% of awards) with no subcontract footprint. The vendor holds two active single-award indefinite delivery contracts with the U.S. Army Corps of Engineers, St. Paul District: a $416,790 ceiling contract awarded August 8, 2024, running through July 31, 2027, and a $250,000 ceiling contract awarded May 23, 2023, running through May 31, 2027. The $416,790 IDC anchors the vendor's current work and funds delivery orders across Minnesota, Wisconsin, North Dakota, South Dakota, Iowa, and Michigan. Recent representative task orders include a $15,000 firm fixed-price delivery order for year-one laboratory testing of soil samples (April 17, 2025, ultimate completion January 31, 2026), a $15,365 delivery order for unconsolidated-undrained triaxial compression testing and embankment evaluation (March 3, 2025, completion August 19, 2025), and a $9,630 delivery order for laboratory testing of soil samples at the Red River Structure cofferdam in Fargo, North Dakota (April 21, 2025, completion January 31, 2026). The vendor also holds task orders under two predecessor IDCs: W912ES23D0008 (14 task orders, $61 thousand combined value) and W912ES21D0007 (10 task orders, $42 thousand combined value).

Customer concentration is extreme: the Department of the Army Corps of Engineers accounts for 100% of the vendor's recorded federal award footprint, with 41 awards totaling $1.2 million in combined potential value. The Corps' St. Paul District Engineering office concentrates 24 awards and $437 thousand of that value, making it the vendor's sole operational customer. The vendor's federal footprint spans 66 total awards with combined potential value of $1.6 million and combined dollars obligated of $791 thousand (48% of potential value). Activity has tracked at six to ten delivery orders annually from 2022 through 2025, with only one award appearing in 2026 (the February 27, 2026 soil testing delivery order at Grand Encampment valued at $6,143). The primary service categorization falls under NAICS 541512 (Testing Laboratories and Services), with 65 of 66 awards coded to that category; PSC coding splits predominantly between Equipment and Materials Testing for Nonmetallic Crude Materials (37 awards) and Special Studies/Analysis—Soil (18 awards).
