Medical Science & Computing, LLC

Medical Science & Computing, LLC, a for-profit limited liability company and child entity of Guidehouse Inc., operates as a prime contractor (100% of recent awards) supplying professional, scientific, and technical staffing and operational support services to the National Institutes of Health (NIH) and its components. Headquartered in McLean, Virginia, the company competes full-and-open without set-aside designations across its federal portfolio, serving primarily civilian health research agencies through labor-hours and firm-fixed-price delivery orders and BPA calls.

Medical Science & Computing's customer base concentrates heavily on NIH. The top five customer agencies account for 95% of recent awards and 88% of combined potential value, led overwhelmingly by the National Institute of Allergy and Infectious Diseases (859 awards, $1.05 billion combined potential value). The National Heart, Lung, and Blood Institute (208 awards, $26 million), NIAID's Division of Extramural Awards Acquisitions (203 awards, $152 million), the National Institute on Drug Abuse (157 awards, $24.5 million), and the NIH Office of Logistics and Acquisition Operations (137 awards, $57.9 million) round out the active set. The concentration on NIAID and other specific NIH institutes is characteristic—Medical Science & Computing functions as a mission-critical staffing vendor for federal biomedical research operations.

The vendor anchors its work on two principal parent vehicles: the Indefinite Delivery Contract HHSN272201500015I (403 task orders, $204 million combined potential value) and the NIAID Professional, Scientific and Technical Support Services IDIQ (340 task orders, $261.3 million combined potential value), along with the Indefinite Delivery Contract HHSN272201000046I (328 task orders, $83.1 million), the GSA Multiple Award Schedule (233 task orders, $224.9 million), and The Professional Services Schedule (219 task orders, $55.3 million). These vehicles position the vendor as a recurring supplier across the NIH enterprise and federal civilian health agencies.

Concrete recent work reflects the vendor's core capability: professional, scientific, and technical staffing and operational support. Representative delivery orders include a $671.6 thousand task under the NIAID Professional, Scientific and Technical Support Services IDIQ for support to the NIAID Director's Office of Operations (awarded February 24, 2026); a $584.8 thousand labor-hour delivery order to the NIAID Division of Intramural Research (awarded March 4, 2024); multiple six-figure BPA calls under the NIH Multiple Award Schedule for specialized positions including clinical research coordinators, lab technicians, statisticians, biologists, MRI technologists, and chemists supporting the National Heart, Lung, and Blood Institute's multiple branches and centers; and a $58.5 million ten-year indefinite delivery contract with the National Institute of Diabetes and Digestive and Kidney Diseases for operating the NIDDK Central Data Repository. The vendor also supplies specialized clinical support services to the NIH Clinical Center, including supplemental clinical research and regulatory support staffing ($750 thousand BPA call, June 27, 2023). Work spans laboratory operations, clinical protocol support, data management, patient care coordination, and specialized research functions across NIH's intramural and extramural operations.

Activity has declined recently. Awards per year fell from 224 in 2022 to 158 in 2023, 74 in 2024, 17 in 2025, and 3 year-to-date in 2026. Forty awards with ultimate completion dates in the next twenty-four months carry combined potential value of $22.3 million—a recompete exposure window reflecting the vendor's reliance on renewal and task-order vehicles. The combined potential value across all awards stands at $1.8 billion, with $1.02 billion obligated (57% of potential).

On federal services contracts captured in the Service Contract Inventory (SCI) between FY2022 and FY2024, Medical Science & Computing reported $176.2 million in invoiced revenue across 680 records as a prime contractor (673 as prime, 7 as named subcontractor). SCI-reported FTE delivery scaled from 1,100 FTEs in FY2022 to 1,911 FTEs in FY2023, then declined sharply to 248 FTEs in FY2024—consistent with the declining award trajectory. On federal services contracts, the vendor's government-paid hourly rates ran a median of $88.69/hr, with rates spanning $27.82/hr at the tenth percentile to $169.76/hr at the ninety-ninth percentile. Across SCI-reportable prime contracts, subcontractors accounted for an average of 2% of total contractor hours, with 37 named subcontractors reported—indicating the vendor builds its own delivery teams rather than relying on subcontractor capacity.

The vendor competes exclusively in full-and-open procurements without set-aside designations, positioning it as a competitor in unrestricted federal health research staffing and operational support markets. Its core NAICS concentration sits in All Other Professional, Scientific, and Technical Services (1,233 awards) and Administrative Management and General Management Consulting Services (224 awards), with PSC-level work concentrated in Support—Professional: Other (1,188 awards) and Support—Management: Contract/Procurement/Acquisition Support (289 awards). Medical Science & Computing operates as a subsidiary of Guidehouse Inc., a broader federal consulting and professional services enterprise, though the source does not indicate cross-subsidiary teaming or shared capacity utilization.
