JSK Diego Services LLC

JSK Diego Services LLC, operating through its J&J Worldwide Services Division, is a construction and facilities maintenance contractor that delivers repair, renovation, alteration, and installation services for U.S. military infrastructure as a prime contractor (100% of recent awards) competing in full and open competition without set-aside designation. Headquartered in Fort Worth, Texas, JSK Diego is a subsidiary of J & J Maintenance Inc., a for-profit Subchapter S corporation, and competes exclusively on competitively awarded delivery orders under a single parent indefinite-delivery/indefinite-quantity contract with no reliance on small business set-asides or reserve vehicles.

JSK Diego's federal footprint is concentrated almost entirely on facilities maintenance and repair at Naval Support Facility Diego Garcia in the British Indian Ocean Territory. The vendor holds 45 prime delivery orders under the Diego Garcia and British Indian Ocean Territory Multiple Award Construction Contract 2021-2026, a $448 million IDIQ awarded by Naval Facilities Engineering Command, structured as a U.S.-U.K. joint venture requiring minimum participation of 60% U.S. and 20% U.K. entities. The IDIQ provides general building construction, repair, renovation, alteration, and design services for shore facilities in the region. JSK Diego's work is predominantly HVAC system replacements, electrical upgrades, runway repairs, fire protection installations, fuel and water system work, facility renovations, and building-specific infrastructure projects. Representative recent delivery orders include a $17.1 million repair to the air cargo terminal (facility F-352) awarded March 2024, a $6.24 million water wells and piping repair project awarded April 2022, and a $4.57 million Thunder Cove Support Facility repair contract awarded April 2025.

Customer concentration is stark: the Department of the Navy Installations Command accounts for 26 awards (94% of the combined potential value of $514.3 million) and dominates both count and dollar share. The remaining four customers — Defense Logistics Agency Energy (5 awards, $15 million), Department of the Air Force Pacific Air Forces (8 awards, $13.6 million), Naval Facilities Engineering Command (4 awards, $3.7 million), and the Office of Naval Research (1 award, $2.1 million) — together represent only 6% of potential value. All 44 task orders flow through the single Diego Garcia IDIQ parent vehicle with $101.3 million in combined potential value. JSK Diego operates as a pure prime contractor with no subcontract exposure in the source data.

Activity grew substantially from 2022 through 2025 (14 awards in 2022 to a peak of 13 in 2025), though the source captures only one award in 2026 as of the snapshot date. Within the next twenty-four months, eight awards carrying combined potential value of $32.1 million face ultimate completion and recompete risk. Work is performed entirely at Diego Garcia and subordinate facilities in the British Indian Ocean Territory. The vendor's primary NAICS coding is Commercial and Institutional Building Construction; PSC category concentration clusters on HVAC maintenance and repair (7 awards), fuel supply facility repair (4 awards), and water supply facility repair (4 awards). The contract vehicle is reserved for U.S.-U.K. joint ventures and is competed under full and open procurement — JSK Diego does not participate in 8(a), HUBZone, SDVOSB, or other set-aside categories in its federal posture. All task orders carry firm fixed-price terms with no set-aside designations, reflecting the vendor's positioning as a prime-tier competitor on this strategically important forward-deployed military construction vehicle.
