The National Institute on Aging requires repairs to its Mobile Research Vehicle 1 (MRV1), a customized 50-foot trailer used for a longitudinal community-based health study. The government intends to award a firm-fixed-price purchase order on a non-competitive basis to LifeLine Mobile in Columbus, Ohio, as the only source with the original blueprints and repair history. The government will transport the trailer from Baltimore, Maryland, to LifeLine Mobile in Columbus, Ohio, and back for the repairs. This requirement is set aside for small businesses under NAICS code 336212. No budget amount or submission timeline is specified in the description.
