About the company
GKG Contractors LLC, an SBA-certified 8(a) joint venture based in Isabela, Puerto Rico, delivers facilities maintenance, base operations support, and infrastructure repair services to the Department of the Navy as a prime contractor across single-award and task-order vehicles. The vendor is minority-owned, woman-owned, HUBZone-designated, and self-certified as a small disadvantaged business; it competes predominantly under 8(a) set-asides (Competitive 8(a) and 8(a) Sole Source) and is a subsidiary of Genco General Contractors of Puerto Rico Corp., itself a woman-owned small business.
GKG's federal portfolio centers on facilities support and infrastructure repair for Naval installations. Recent work includes a $122.1 million single-award Competitive 8(a) Indefinite Delivery Contract for base operations support services at Naval Support Activity Mid-South in Millington, Tennessee (awarded October 2025, running through March 2031), a $33.4 million single-award Competitive 8(a) IDC for multi-function support services at Naval Station Mayport, Florida (awarded February 2025, running through July 2031), and a $3.1 million single-award 8(a) Sole Source IDC for storage tank inspection, testing, certification, maintenance, and repair services across Naval Facilities Engineering Command Southwest installations (awarded February 2025). Task-order work under these vehicles includes HVAC replacement ($138,950), shower pan and base replacements ($113,651), VRF unit replacement ($130,373), storage tank recurring services ($126,010), chiller rentals ($40,725), and compressor and coil replacements in the sub-$40,000 range. GKG also holds delivery orders for electrical infrastructure support (transformer replacement, crossarm insulation work, rapid-flashing beacon installation), valve and hydrant replacement, tree trimming along electrical lines, and facility repairs at multiple Navy and Naval Facilities Engineering Command installations nationwide.
Customer concentration is singular and acute: the Department of the Navy accounts for 100% of named awards. Within Navy, the split is Department of the Navy Installations Command (32 awards, $11.4 million combined potential value), Naval Facilities Engineering Command (10 awards, $4.3 million), and U.S. Pacific Fleet Forces (3 awards, $44.9 million). The two largest customers by potential value are a single Department of the Navy award (the $122.1 million NSA Mid-South BOS IDC) and Pacific Fleet Forces (which funds the Naval Station Mayport $33.4 million multi-function support services IDC). Task-order activity concentrates under the Indefinite Delivery Contract N6945025D0036 (24 task orders, $9.2 million combined value), which appears to be the NSA Mid-South BOS vehicle, and IDC N6247325D5217 (10 task orders, $1.2 million), the storage tank inspection and maintenance contract. Place of performance spans Millington, Tennessee; Jacksonville, Florida; San Diego and Lemoore, California; and Seal Beach, California.
GKG's award trajectory shows marked growth: six awards in 2024 (first in June), nineteen in 2025, and twenty-three in 2026 to date. Combined potential value across all forty-eight awards is $183.4 million, with $23 million obligated (13% realization). Only one award faces ultimate completion within the next twenty-four months ($5.8 million combined potential value), indicating minimal near-term recompete pressure. The vendor holds 98% of awards as prime contractor and 2% as subcontractor (a single sub award under RQ Construction, LLC for ground maintenance services at Naval Station Mayport, issued June 2026). Work is dominated by Facilities Support Services NAICS (40 awards), followed by building and electrical construction and repair (5 combined awards). The firm has not held positions on government-wide acquisition contracts or civilian agency vehicles; Navy alone is the customer base.
