The National Institutes of Health is seeking information from qualified small businesses for a contract to supply unleaded fuel, E-85, and diesel for its fleet of approximately 550 government-owned vehicles. Performance would take place at NIH facilities in Bethesda and Poolesville, Maryland, with a contract structure anticipated to include a one-year base period and four one-year option periods. The notice is for market research only and does not constitute a solicitation or obligate the government to award a contract. Respondents must be small businesses under NAICS 424710 (size standard of 225 employees) and should submit a capability statement demonstrating their ability to provide fuel delivery services. The government will use responses to help determine acquisition strategy, including whether a set-aside is feasible.
