The NIH, through OLAO/OALM, intends to award a sole-source firm-fixed-price purchase order to Protective Industrial Products, Inc. for multiple models of Honeywell BSL-4 positive pressure suits. The total estimated value is $3,075,975 inclusive of all options, with award projected no later than August 17, 2026, and a period of performance from that date through August 16, 2029 (base plus two option years). The suits are for use by NIH and CDC personnel and researchers in high-containment BSL-4 laboratories, including NIH’s NIAID and CDC facilities. The procurement supports mission-critical functions, with an estimated demand of ~200 suits per year, and the Honeywell brand is required because no functional equivalent integrates with existing infrastructure. The suits must meet comprehensive safety and performance criteria, including size options, airflow, HEPA filtration, temperature limits, visibility, weight, and durability requirements.
