Grose Construction, LLC

Grose Construction, LLC, a tribally-owned, Native American-owned, and SBA 8(a)-certified limited liability partnership headquartered in Aberdeen, Maryland, provides minor construction, facility renovation, demolition, secure facility upgrades, and site preparation services to the Department of the Army as a prime contractor (88% of recent awards), with ancillary work as a subcontractor under defense primes. The firm competes across both set-aside and full-and-open vehicles, with recent work split between 8(a) Sole Source and non-set-aside designations.

Grose's customer base is heavily concentrated in Army installations and commands. The top two funding entities — the Department of the Army Materiel Command Research Development and Engineering Command (RDECOM) and the Department of the Army Test and Evaluation Command (ATEC) — account for 88% of recent awards and 100% of combined potential value. RDECOM anchors the dollars ($51.6 million across five awards), while ATEC dominates award count (10 awards, $15.6 million). Secondary customers include the Department of the Interior US Geological Survey (one $4 million award for a Bureau of Indian Affairs office relocation and renovation in Herndon, Virginia), the Maryland Army National Guard, and the Army Corps of Engineers. Most work is performed at Aberdeen Proving Ground, Maryland, with the exception of the BIA project.

Grose holds a $49.99 million single-award 8(a) sole-source indefinite-delivery contract (W911QX-24-D-0025) with RDECOM running through September 2027, under which two delivery orders have been issued: a $882.78 thousand firm-fixed-price order (September 2024) for secure facility upgrades to Building 403, and a $553.85 thousand 8(a) sole-source delivery order (May 2026) for Edgewood Skippers Point planning and design. Representative prime work also includes a $122.67 thousand firm-fixed-price definitive contract awarded by ATEC in September 2026 for site preparation, foundation construction, utility connections, and site restoration for a government-furnished SCIF, and the BIA renovation contract from 2022. Grose also sits on a second IDIQs with task-order activity under other Army IDVs.

Recent activity has been episodic: one award in 2017, one in 2022, two in 2024, three in 2025, and two in 2026. Only two awards (combined potential value $677 thousand) face ultimate completion within the next twenty-four months, indicating modest recompete pressure. In its subcontractor role, Grose delivers construction and security renovation services to KBR Wyle Services (maintenance services at Aberdeen Proving Ground, September 2025) and Johnson Controls Building Automation Systems (chillers and DDC installation and building renovations at Aberdeen Proving Ground, January and June 2025). Work is categorized primarily under remediation services (8 awards) and commercial and institutional building construction (5 awards), with secondary PSC concentration in earth moving and excavating equipment and repair or alteration of office buildings.
