About Geotechnical Construction, Inc.
Geotechnical Construction, Inc. is a women-owned, economically disadvantaged small business based in Mt. Olive, Illinois that specializes in civil infrastructure construction and maintenance services for federal agencies. The company holds SBA certifications as both a Women-Owned Small Business (WOSB) and a Certified Economically Disadvantaged Women-Owned Small Business, positioning it competitively for federal procurement opportunities that prioritize diverse supplier engagement. Registered in SAM.gov since June 2001, Geotechnical Construction operates as a for-profit corporate entity focused on delivering infrastructure improvement projects across the United States Army Corps of Engineers' civil works portfolio.
Geotechnical Construction has demonstrated extensive experience delivering a diverse range of civil infrastructure services through federal contract awards totaling millions of dollars. The company's past delivery orders and task orders—spanning from 2021 through 2025—encompass road maintenance and rehabilitation, parking lot construction and repairs, facilities maintenance and upgrades, dam and spillway improvements, turf maintenance, rock placement, comfort station and fish cleaning station replacements, dump station and showerhouse installations, asphalt work, relief well drilling, and general civil works support. All of the company's federal contract awards have been issued by the U.S. Army Corps of Engineers across multiple districts and project locations, primarily in Illinois (Lake Shelbyville, Shelbyville) and Missouri (Wappapello Lake, Mark Twain Lake, and Mel Price Lock and Dam system). Contract awards have ranged from minor call orders of $5,000 to major delivery orders exceeding $2.3 million, with most delivery orders representing firm fixed-price contracts without set-aside designations, though several early awards carried total small business set-aside designations. The company has operated exclusively as a prime contractor on these awards, with no identified subcontractors listed in the contract documentation.
Geotechnical Construction currently holds five federal Indefinite Delivery Contracts with the U.S. Army Corps of Engineers, representing a total ceiling value of $73 million. The largest and most recent IDC, awarded June 17, 2025, is a $24 million single-award contract set aside for small businesses for facilities construction, maintenance, and repair services at the Mark Twain Lake Project in Missouri, with a completion date of June 16, 2030. A second $24 million single-award IDC, awarded March 1, 2024 without set-aside designation, covers infrastructure construction and maintenance at Wappapello Lake in Missouri through August 31, 2029. The company holds two additional $24 million small business set-aside IDCs awarded by the Corps of Engineers on February 1, 2024 and September 14, 2023 for infrastructure and park roads construction services at Lake Shelbyville in Illinois, both extending through 2028. Finally, Geotechnical Construction maintains a $1 million single-award Blanket Purchase Agreement with the Corps of Engineers for services supporting the Mel Price Interim Operating Plan, originally established March 16, 2023 and expiring March 21, 2025. These IDVs have supported the issuance of numerous task orders and delivery orders over multiple years, with individual orders typically ranging from $1 million to $5 million annually, providing the company with a substantial and stable contracting relationship with the Army Corps of Engineers across its civil works operations.
