About RSI Services LLC

Written by GovTribe AI ·

RSI Services LLC, an SBA 8(a) certified Alaskan Native Corporation-owned small disadvantaged business based in Oak Ridge, Tennessee, performs environmental remediation, site characterization, radiological cleanup, and waste management services for federal agencies, primarily as a prime contractor (85% of recent awards). The vendor operates as a division of parent company Asrc Industrial Services LLC and maintains three named joint-venture subsidiaries: RSI Cape JV LLC, RSI Alliant JV LLC, and RSI Amentum Environmental Solutions LLC. RSI's award footprint is dominated by 8(a) sole-source and competitive set-aside work, with roughly $141.8 million in combined potential value across thirteen tracked federal awards since 2021.

RSI's customer concentration is heavily skewed toward the Department of Energy's NNSA and the U.S. Army Corps of Engineers. The top five funding entities account for 85% of awards by count and 98% of combined potential value: the Army Corps of Engineers Engineering District Omaha leads in potential value at $60 million (a two-award IDC vehicle running through February 2027), followed by NNSA at $48.4 million across four awards, Air Force Civil Engineer Center at $14.5 million, and DOE's Office of Environmental Management at $13.2 million. NNSA work centers on nuclear-facility environmental restoration, including a $931,223 delivery order for CERCLA remediation at Bettis Atomic Power Laboratory (March 2026, ultimate completion May 2027) and an $8.7 million delivery order for pre-remediation characterization and remediation at Oak Ridge (September 2022, completion March 2027). Air Force work includes a $14.5 million definitive contract for excavation and disposal of radium-contaminated soil and radiological cleanup at former McClellan Air Force Base in California (June 2024, completion July 2028). Army Corps awards span a $60 million multiple-award 8(a) environmental consulting services IDC (Omaha District, through February 2027) and a $3.1 million 8(a) sole-source time-critical removal action at Staten Island's FUSRAP site (April 2023, completion April 2026).

RSI holds two parent indefinite-delivery vehicles: the $60 million Environmental Consulting Services IDC with Army Corps Engineering District Omaha (Competitive 8(a), February 2022 through February 2027) and a $47 million sole-source IDC with NNSA for environmental remediation, demolition, regulatory compliance, and waste management at nuclear-related sites. Five task orders have been issued against the NNSA vehicle with $14.6 million in combined potential value. Activity has declined in recent years—four awards in 2021 declining to one in 2026—and three awards with $9.7 million in combined potential value face ultimate completion within the next twenty-four months, creating recompete exposure. Across NAICS coding, seven awards map to Remediation Services and two to Environmental Consulting Services, while primary PSC coding centers on Environmental Systems Protection and Environmental Remediation (seven awards). RSI subcontracts to Consolidated Nuclear Security LLC on management and operating contracts for the Y-12 National Security Complex and Pantex Plant (September 2024 sub awards). The vendor's SCI-reported invoiced revenue shows $1.3 million in FY2022 against 0.9 FTEs, with zero revenue reporting in FY2023 and FY2024; government-paid rates on SCI-reportable prime contracts held steady at a median $480.42 per hour, with minimal subcontractor engagement (5% average sub-hours share across prime records). Of the vendor's $141.8 million in combined potential value, $26.8 million has been obligated to date (19% rate), reflecting the long-tail nature of environmental remediation IDCs where task orders trigger obligation increments over multi-year performance periods.
