Glenn Machine Works Inc.

Glenn Machine Works Inc., a small business headquartered in Columbus, Mississippi, provides mobile crane rental and rigging services to federal agencies as a prime contractor on small business set-aside purchase orders and full-and-open awards. The company operates across 97% of its recent federal footprint as a prime, with crane support work anchored to NOAA's Gulf Coast maritime operations and NASA's Stennis Space Center facility in Mississippi.

Glenn Machine Works competes across both total small business set-asides and unrestricted full-and-open solicitations. Recent awards split between total small business set-aside designations (the $50,670 NOAA Gulfport Pier crane modification in January 2026, the $31,630 NOAA Ship Nancy Foster support contract in July 2023, and the $16,080 NOAA Pascagoula crane service order in August 2022) and sole-source or competitive awards with no set-aside (the $85,650 NASA Stennis wire rope inspection crane rental in February 2025 and the $83,960 NASA Stennis B test stand crane rental in January 2024). The company's NAICS footprint emphasizes overhead traveling crane and hoist manufacturing and specialty construction contracting, with PSC codes dominated by equipment rental (Lease Or Rental Of Equipment–Miscellaneous, Winches/Hoists/Cranes/Derricks, and Cranes And Crane-Shovels).

Customer concentration skews heavily toward Gulf Coast and Mississippi-based federal operations. The National Aeronautics and Space Administration Stennis Space Center anchors the top-customer ranking by potential value at $1 million across two awards, followed by NASA's Shared Services Center ($183 thousand across five awards), NOAA ($116 thousand across five awards), and the National Park Service National Office ($90 thousand). By award count across a 43% coverage slice, the Navy's Facilities Engineering Command (seven awards, $40 thousand) and Installations Command (six awards), the Air Force Air Education and Training Command (six awards, $66 thousand), and NOAA (five awards) lead the active roster. Glenn Machine Works has served 18 distinct customer agencies across its federal footprint.

Activity has been episodic, with one award in 2022, one in 2023, four in 2024, three in 2025, and one in early 2026 — a cumulative trajectory reflecting project-based procurement cycles rather than sustained volume growth. The vendor carries $1.7 million in combined potential value across 67 total awards (prime and sub combined), with $2.5 million already obligated, indicating completed and invoiced work exceeding remaining contract ceilings. Only one award faces ultimate completion in the next twenty-four months, posing minimal near-term recompete cliff exposure.

Glenn Machine Works subcontracts minimally (3% of awards): two recent sub-awards to Huntington Ingalls Incorporated on DDG 1000/1001 modernization crane rental (October 2025) and LHA 9 design and construction support (November 2024) represent its nascent defense shipbuilding exposure. The vendor's capability footprint centers narrowly on mobile crane rental with operator and rigging support for equipment mobilization, demobilization, and on-load/off-load operations at maritime research facilities and DoD shipyard installations.
