The Grieve Corporation

The Grieve Corporation, doing business as Grieve Corp, manufactures and delivers industrial ovens, furnaces, and specialized thermal processing equipment to the federal government as a prime contractor on 98% of recent awards, competing predominantly full-and-open with occasional Total Small Business set-asides. Grieve Corp is a for-profit Subchapter S Corporation headquartered in Round Lake, Illinois, with an established SAM.gov registration since 2001. The company specializes in custom industrial heating equipment across NAICS 333994 (Industrial Process Furnace and Oven Manufacturing) and PSC 34 (Industrial Furnaces, Kilns, Lehrs, and Ovens), with 108 of 188 recent awards concentrated in that furnace-and-oven PSC.

Grieve's capability footprint centers entirely on custom and standard industrial thermal equipment — electric and gas-fired ovens, tempering furnaces, pit furnaces, box furnaces, shelf ovens, and drying ovens — sold as purchase orders to defense and civilian agencies. Representative recent prime contracts include a $530,440 Total Small Business award from the Army Materiel Command's TACOM Life Cycle Management Command (June 2025) for two pit tempering furnaces per specification, a $154,000 firm fixed-price order from the United States Mint (September 2025) for Grieve refurbishment at Round Lake with completion through September 2027, a $92,698 purchase order from the Denver Mint (December 2024) for an industrial tempering oven, and a $44,661 order from EPA Region 6 (September 2026) for a Grieve oven and accessories with place of performance in Byng, Oklahoma.

Customer concentration is defense-heavy and distributed. The top five customer organizations account for 41% of award count and 54% of combined potential value, led by the Department of the Navy (28 awards, across Naval Sea Systems Command with 13 awards and Naval Air Systems Command with 9 awards), the Department of the Army Materiel Command (20 awards split between TACOM Life Cycle Management Command with 9 awards and Contracting Command Redstone Arsenal with 11 awards), the Department of the Air Force (16 awards), and the United States Mint (2 awards, $247 thousand combined potential value). Navy dominates by count; Army TACOM dominates by dollars with $677 thousand combined potential value across 9 awards. Grieve has worked with 35 distinct customer agencies across the federal footprint.

Parent vehicle participation is minimal. Grieve places task orders under five indefinite delivery contracts (N0060085C1483 with 2 task orders, and four others with 1 task order each), reflecting primarily single-award or agency-specific delivery mechanisms rather than government-wide vehicles. Activity has been steady but modest — 3 awards in 2022, 3 in 2023, 2 in 2024, 2 in 2025, and 3 in 2026 year-to-date — with combined potential value of $3.7 million across all 188 recent awards. Notably, combined dollars obligated exceed combined potential value at 200%, indicating extensive prior performance and re-obligation. Two awards face ultimate completion within the next twenty-four months with combined potential value of $199 thousand.

Grieve's subcontractor footprint is minimal (2% of recent awards). It supplied General Dynamics OTS (Wilkes Barre) with Grieve Model HD-484848-HT gas-fired box furnaces for a 155mm capacity expansion project supporting the M795 and M1128 munitions lines (February 2026), Asrc Federal Facilities Logistics with a Grieve Model WTH566-800 electrically heated furnace under task-order performance (September 2024), and Intuitive Research and Technology Corporation with a modified Grieve Model LD-550 electrically heated top oven for the RNRE Prototype and Development II program (August 2022).
