This amendment adds VAAR 852.219-75, which requires offerors to certify compliance with limitations on subcontracting for SDVOSB/VOSB contracts. For services, the contractor cannot pay more than 50% of the government-paid amount to non-VIP-listed firms; for general construction, the limit is 85%, and for special trade construction, 75%. The signed certification must be submitted with the offer, or the response will be deemed ineligible for evaluation and award. False certifications may result in penalties, including referral for suspension or debarment, fines, and prosecution.

The amendment provides responses to questions about using proprietary equipment, clarifying that bidders may offer their own water monitoring hardware and analytics platform if they meet the requirements of VA Directive 1061. The hardware must operate above 124°F, be installed on copper plumbing in seven patient-care buildings, and monitor pH, residual biocide, turbidity, and pressure. The software must offer continuous data logging, out-of-range alerts, cloud-based real-time access, historical data storage per VA cybersecurity standards, compliance reporting, and automatic trending. The awarded contractor will be responsible for removing and disposing of the existing proprietary system. The assigned NAICS code will not be changed.
