The Department of Health and Human Services, specifically the National Institutes of Health (NIH), is seeking to negotiate a sole source contract with Advanced Cleanroom Microclean for cleaning services at its Clinical Center in Bethesda, Maryland. The requirement is for cleaning services to maintain compliance with Good Manufacturing Practice (cGMP) regulations, ensuring a sterile environment crucial for patient safety and healthcare during clinical research. This contract serves as a temporary "bridge" to provide continuity of service while a new main cleaning services contract is being finalized, with an estimated performance period of approximately two months from July to August 2025. Interested parties may submit capability statements by June 30, 2025, to Lu Chang at lu-chang.lu@nih.gov for consideration.
