About Shellback Construction LLC
Shellback Construction LLC, a service-disabled veteran-owned small business (SDVOSB) based in Brenham, Texas, provides commercial and institutional building construction, renovation, and infrastructure repair services to federal agencies as a prime contractor. The firm operates exclusively as a prime across its recent federal footprint (100% prime awards) and competes predominantly under SDVOSB and small-business set-asides.
Shellback is structured as a limited liability partnership and holds concurrent SBA certifications as both an SDVOSB and a Veteran-Owned Small Business, expiring January 20, 2027. The vendor qualifies as a self-certified small disadvantaged business. The concrete capability portfolio centers on building additions, renovations, HVAC upgrades, foundation repair, drainage system installation, and facility upgrades at civilian federal campuses. Representative prime work includes a $2.23 million firm-fixed-price definitive contract with the USDA Agricultural Research Service for additions and renovations to the Somerville Main Building in Somerville, Massachusetts (July 2022 through November 2023, set aside for total small businesses); an $89,001 USDA contract for office and HVAC renovation at the Somerville Pecan Station in College Station, Texas (completed January 2022); and a $44,445 USDA contract for replacement of a floor drain system in a greenhouse facility at the Southern Plains Agricultural Research Center in College Station, Texas (October 2025 through March 2026, set aside for total small businesses).
Customer concentration is heavily skewed toward the Department of Veterans Affairs National Cemetery Administration (NCA), which accounts for five awards carrying $49.3 million in combined potential value—96% of Shellback's total potential value. The USDA Agricultural Research Service accounts for three awards worth $2.4 million, and the Department of Transportation Federal Aviation Administration holds one micro-award of $15,000. The top-customer rankings by award count and potential value track identically, indicating that NCA dominates both volume and dollars. Shellback holds a $49 million multiple-award IDIQ contract with the NCA National Cemetery Administration for construction services across the NCA Continental District, running through December 3, 2034, set aside for SDVOSBs. Four task orders have been issued against this IDIQ (combined potential value $267,000). Recent NCA delivery orders include a $79,382 repair of the fire alarm system at Dallas-Fort Worth National Cemetery (awarded June 10, 2026, ultimate completion August 19, 2026), a $132,322 descoped task order to connect a storm sewer at San Antonio National Cemetery (awarded November 24, 2025, originally scheduled for completion April 21, 2026), and a $54,960 replacement of a sewage lift station at Fort Sam Houston National Cemetery (awarded May 29, 2025, completed September 6, 2025).
Activity has been episodic but growing: one award per year in 2021 and 2022, then a gap in 2023, followed by five awards in 2025. The most recent award (June 2026) is the Dallas-Fort Worth fire alarm repair. Two awards carrying combined potential value of $94,000 reach ultimate completion within the next twenty-four months, creating modest recompete exposure. Service Contract Inventory data shows $2.2 million in SCI-reportable invoiced revenue across three prime records, with $2.1 million invoiced in FY2023 supporting 2.0 FTEs and nominal activity in FY2022 and FY2024. On federal services contracts captured in SCI, government-paid rates ranged from roughly $589/hr at the tenth percentile to a median around $994/hr, with senior labor pricing reaching $1,399/hr at the ninetieth percentile. The vendor delivered no subcontracted labor on SCI-reportable primes—zero percent sub-hours share—indicating Shellback builds its own delivery teams rather than leveraging subcontractors.
