The Department of Veterans Affairs intends to award a sole-source firm-fixed-price contract for radiopharmaceuticals and associated supplies to Sierra Radiopharmacy LLC due to urgent delivery requirements. The period of performance is September 1, 2026, through August 31, 2027. Only one source can meet the need for four-hour and same-day delivery for urgent diagnostic imaging and therapeutic procedures, even during winter months when weather impacts road conditions between California and Nevada. Services require delivery to VA facilities in that region. Any responsible source that believes it can meet these requirements may submit supporting documentation for consideration.
