The NIH, on behalf of the CDC, intends to award a sole-source, firm-fixed-price purchase order to Protective Industrial Products, Inc. for Honeywell brand BSL-4 positive pressure suits. The total estimated value, including all options, is $3,075,975. The projected award date is no later than August 17, 2026, with a period of performance running through August 16, 2029, if all option years are exercised. The suits will support personnel and researchers at NIH and CDC high-containment BSL-4 laboratories. The required suits must meet detailed safety and performance criteria, including specific airflow, sizing, durability, and decontamination requirements.
