The Department of Veterans Affairs intends to negotiate and award a firm-fixed-price, sole-source Requirements contract to a Large Business for brand-name Fresenius 5008XTM CAREsystem Hemodiafiltration Units and associated accessories. This is a Notice of Intent to Sole Source, not a request for competitive quotes, and no solicitation is available; interested parties may respond with sufficient detail to demonstrate their capability. The applicable NAICS code is 334510 with a 1,250-employee small business size standard. The equipment is used for extracorporeal renal replacement therapy, combining diffusion and convection to remove toxins and fluid from blood. Responses will be considered, but the Government is not obligated to compete the requirement and will not reimburse any response costs.
