Sustainment & Restoration Services, LLC

Sustainment & Restoration Services, LLC, a tribally owned 8(a) certified small disadvantaged business subsidiary of the Oneida Nation, delivers environmental remediation, facility support, instructional services, and technical consulting to federal defense and civilian agencies as a prime contractor on 98% of its recent awards. The firm operates from Wauwatosa, Wisconsin, and carries Native American owned, Indian Economic Enterprise, and Indian Small Business Economic Enterprise designations across its primary entity and ten subsidiary joint ventures structured to compete under specific vehicle and set-aside categories.

The vendor's customer base spans 43 distinct federal agencies, with concentration heavily weighted toward Department of Defense environmental remediation work. The top five agencies by award count—Naval Education and Training Command (67 awards, $12.7 million potential value), Army Corps of Engineers Engineering District Los Angeles (26 awards, $43.1 million), Army Corps of Engineers Engineering District Sacramento (19 awards, $239.2 million), Naval Facilities Engineering Command (17 awards, $34.9 million), and Air Force Civil Engineer Center (13 awards, $65.6 million)—account for 55% of all awards. By potential value, however, Navy Sea Systems Command dominates at $10 billion across only two awards, reflecting the weight of two massive OASIS+ indefinite-delivery contracts awarded in late 2024. Army Corps of Engineers Environmental Remediation work at Edwards Air Force Base and other installations anchors recurring multi-million-dollar delivery-order streams; a single $61.876 billion Edwards AFB IDIQ ceiling (8(a) sole source, September 2023) has generated $40 million plus in task orders. This concentration creates both stability and recompete exposure: 20 awards valued at $75.2 million reach ultimate completion within the next twenty-four months.

Capability framing reflects the award pattern. The vendor competes predominantly on environmental remediation—hazardous, toxic, and radioactive waste management, per- and polyfluoroalkyl substances investigation and remediation, groundwater monitoring, five-year Defense Environmental Restoration Program reviews, and site assessments. Instructional support services and technical consulting represent secondary but sustained revenue streams. A $19.614 billion definitive contract for the Arnold Air Force Base Optimized Remediation Contract (8(a) sole source, June 2023, through June 2033) exemplifies the scale of environmental-remediation work. A $4.127 million Air Force Civil Engineer Center definitive contract for conceptual site modeling across eight Air Force installations including McConnell AFB, Creech AFB, and multiple LRRS locations (September 2023, 8(a) sole source) demonstrates multi-installation scope. Instructional support shows granular delivery orders—a $250 thousand Naval Postgraduate School writing center maintenance contract (July 2024, 8(a) sole source under GSA Multiple Award Schedule), and dozens of $20,000–$100,000 course delivery and instructor support orders through Naval Education and Training Command and Defense Media Activity.

Vehicle position spans both set-aside and unrestricted platforms. The vendor holds three OASIS+ IDIQs awarded December 2024—8(a) Competitive ($999.999 billion ceiling), Total Small Business ($999.999 billion ceiling), and Unrestricted ($999.999 billion ceiling)—all running through December 2029 and representing entry points for government-wide task-order competition. A $61.876 million single-award Army Corps of Engineers Edwards AFB Environmental Remediation IDIQ (September 2023, 8(a) sole source, through September 2028) and a $49.9 million Army Corps single-award environmental remediation IDIQ with emphasis on HTRW and PFAS (September 2023, 8(a) sole source, through September 2028) anchor the largest recurring delivery streams. A $14.5 million Naval Facilities Engineering Command operational range clearance single-award IDIQ (February 2024, 8(a) sole source, through February 2029) and a $5.366 million Navy instructional support IDIQ (September 2023, 8(a) sole source, through December 2026) serve smaller but stable task-order pipelines. The vendor maintains 36 active task orders on GSA Multiple Award Schedule vehicles valued at $103.7 million combined, split across instructional services, technical writing, facility maintenance, and research support. An Army Training and Doctrine Command IDIQ for instructor and multimedia support services ($41.441 million ceiling, competitive 8(a), March 2023–February 2028) places the vendor on JBSA Fort Sam Houston–based delivery-order stream.

Set-aside posture is definitional. The vendor competes predominantly under 8(a) sole source designations on its largest IDIQs and definitive contracts. Recent awards show mixed set-aside discipline: a $13.23 million Air Force Edwards AFB operations and maintenance delivery order (September 2025) and a $6.217 million Air Force pre-ORC delivery order at Edwards AFB (April 2025) carried no set-aside, suggesting unrestricted competition on established platforms. The vendor also holds seats on Total Small Business and Unrestricted OASIS+ platforms, enabling it to compete full-and-open on government-wide solicitations. The preponderance of 8(a) sole source and competitive 8(a) awards across its footprint indicates the firm leverages tribal ownership and small business certification as core acquisition strategy.

Teaming patterns show the vendor operates as a prime contractor on nearly all work; only four subcontract awards appear in the portfolio. Across SCI-reportable service contracts (FY2022–FY2024), the vendor billed $15.5 million in prime services—$3.5 million in FY2022 (12.2 FTEs), $6.4 million in FY2023 (18.3 FTEs), and $5.6 million in FY2024 (18.0 FTEs)—with zero average sub-hours share on prime records, indicating delivery of services through its own workforce rather than subcontracted labor. Government-paid hourly rates on SCI-reportable work ranged from $68.02/hr at the 10th percentile (entry-level field labor) to $402.94/hr at the 90th percentile (senior technical and program management roles), with a median of $152.90/hr, consistent with environmental remediation technician and junior professional pricing. When appearing as a named subcontractor, the vendor supported Tetra Tech on Superfund Technical Assessment and Response Team (START) Region 4 program and administrative tasks (October 2023, February 2024) and on Alameda NAS Subsurface In-Situ Waste Characterization technical support (September 2023), as well as Leidos on Base Realignment and Closure PFAS remedial investigation/feasibility study work at six Army BRAC installations (July 2025), signaling selective sub-engagement on large federal environmental programs where it does not hold the prime relationship.

Corporate structure reveals ten subsidiary joint ventures—SRS-ERRG JV, SRS-Cape JV, SRS-RFI JV, SRS Battelle JV, SRS-Alliant JV, SRS-Cape II JV, SRS-BB&E JV, SRS-Ayuda JV, SRS Battelle II JV, and SRS-ERRG II JV—each carrying tribally owned, Indian economic enterprise, and small disadvantaged business designations. The joint-venture naming convention (specific names like Battelle, Alliant, Cape, ERRG) suggests partnerships or teaming vehicles structured to compete on specific large platform IDIQs or agency-directed work; the vendor awards portfolio does not explicitly surface which subsidiary holds which IDIQ or delivery order, but the structure permits vehicle-specific entity deployment while maintaining tribal ownership and certification credentials across the enterprise.

Recent activity shows mixed trajectory. Awards per year peaked at 44 in FY2023, declined to 27 in FY2024, and stand at 10 through October 2025, reflecting either backend loading of large IDIQs (the three OASIS+ awards in December 2024 count as two awards and skew recent volume) or seasonal timing of award notices. Combined potential value across all 258 awards stands at $10.66 billion, heavily anchored by the two Navy Sea Systems Command OASIS+ IDIQs at $999.999 billion ceiling each (placeholder ceilings carrying no real dollar signal), the Arnold AFB ORC at $19.614 billion, and the Edwards AFB remediation IDIQs totaling over $100 million in ceiling. Obligated dollars—$307.9 million across all awards, only 3% of combined potential value—indicate the vendor is early in execution on large indefinite vehicles and relies on periodic delivery-order issuance to convert ceilings into revenue. This posture creates acute recompete exposure: the $75.2 million in awards completing within twenty-four months includes the $8.087 billion Naval Postgraduate School writing coaching and thesis processing sole-source purchase order (ultimate completion July 2025, already expired), suggesting either contract extension or pipeline risk.
