About Graham Plumbing Inc.

Graham Plumbing Inc., a small business based in Heber Springs, Arkansas, provides plumbing installation, maintenance, and repair services to the U.S. Army Corps of Engineers as a prime contractor under total small business set-aside indefinite-delivery contracts. The company operates exclusively as a prime (100% of awards) with no subcontract footprint and competes predominantly under small business set-asides on single-award IDIQs issued by USACE's Little Rock District.

Graham Plumbing's federal footprint is heavily concentrated with a single customer. The U.S. Army Corps of Engineers Engineering District Little Rock accounts for 27 awards (100% coverage across both award-count and potential-value rankings) with $5.8 million in combined potential value, while a second Army Corps line item carries an additional 14 awards valued at $2.4 million. The Defense Health Agency issued one award valued at $47 thousand. Across 42 total federal awards, combined potential value reaches $8.3 million, with only $1.7 million obligated to date (20% realization).

The company holds or has held five active single-award IDIQs with USACE. The most recent is a March 23, 2026 award — a $2,064,850 indefinite-delivery contract (W9127S26QA008) running through January 31, 2031 with a total small business set-aside designation, covering plumbing maintenance across 13 parks and facilities at Greers Ferry Lake (Greers Ferry Dam, Greers Ferry Park, Greers Ferry Project Office). The contract guarantees a $2,500 minimum for the base year (award through January 31, 2027) and includes four one-year option periods. Prior IDIQs include W9127S21D0012 ($1,795,910 ceiling through March 31, 2026, 7 task orders valued at $399 thousand), W9127S18D0002 (11 task orders, $566 thousand), W9127S12D0014 (10 task orders, $320 thousand), and W9127S15D0006 (8 task orders, $339 thousand). Representative recent delivery orders include a $61,160 firm fixed-price task order issued April 1, 2026, for plumbing services at Greers Ferry Project Office under the total small business set-aside, and a $75,320 pre-priced task order awarded September 15, 2025, also at Greers Ferry.

Activity has been modest and episodic — one to two awards per year over the past five years — with only two awards (combined potential value $136 thousand) facing completion inside the next twenty-four months. Graham Plumbing performs the full scope of work directly with no subcontractors identified across any award. Work is classified under NAICS 561210 (Facilities Support Services) and PSC codes emphasizing repair and alteration of recreation facilities and maintenance of recreational buildings. All work is performed in Heber Springs, Arkansas, and is subject to Service Contract Act prevailing wage and fringe-benefit requirements.
