About the company
Clym Environmental Services LLC, a Maryland-based limited liability partnership, provides radiation safety compliance, radioactive materials management, and environmental health and safety services to the National Institutes of Health as a prime contractor, operating predominantly under small business and competitive set-asides across multiple NIH indefinite delivery vehicles.
Clym's customer footprint is heavily concentrated with NIH. The top five customer offices account for 84% of awards, with NIH's Office of Logistics and Acquisition Operations anchoring the largest potential-value share at 57 awards worth $44.6 million combined, followed by NIH's core operations at 25 awards worth $28.8 million and the Office of the Director at 61 awards worth $24.9 million. This concentration reflects Clym's deep operational relationship with NIH's radiation safety and compliance infrastructure across Bethesda facilities and satellite locations. The second ranking by potential value tracks the first closely — the three largest customer offices drive both volume and dollars — with Veterans Affairs and NIH construction programs comprising minimal additional exposure. Recent representative work includes a $509 thousand firm fixed-price delivery order for radiation safety support covering NIH clinical, animal, and laboratory research with radioactive materials (awarded August 2026, extending through February 2027 under total small business set-aside); a $586 thousand compliance services delivery order covering NIH facilities and satellite locations (May–December 2023, no set-aside); and a $239 thousand compliance services delivery order spanning January–April 2023 (also no set-aside). All three orders were issued against indefinite delivery vehicles established in July 2020.
Clym holds task orders on five primary parent vehicles. The Indefinite Delivery Contract HHSN263200500002I carries the largest footprint, with 31 task orders worth $35.1 million combined potential value, followed by HHSN263201500032I (30 task orders, $7.2 million), HHSN263200700001I (28 task orders, $3.9 million), 75N98020D00088 (27 task orders, $6.6 million), and HHSN263201200066I (21 task orders, $4.8 million). Award volume has contracted sharply from five awards in 2021 to one award each in 2025 and 2026; only one award worth $509 thousand faces completion within the next twenty-four months, presenting minimal recompete cliff exposure in the near term. Clym operates almost entirely as a prime (193 of 194 awards, 99%), with one sub-award as a sterilized lab waste disposal and site services subcontractor to Battelle National Biodefense Institute (May 2025). The vendor's primary NAICS concentration sits in Testing Laboratories and Services (115 awards) and All Other Support Services (54 awards), with environmental consulting and hazardous waste collection representing smaller activity streams. SCI-reported service-contract invoicing shows $624 thousand in FY2022 across 3.5 FTEs; no further invoicing appears in the SCI dataset for FY2023–FY2025, reflecting either non-reporting or sub-threshold contract performance during those years. Government-paid hourly rates on SCI prime contracts ran at a consistent $85.73/hour across all percentiles.
