PRESSURE FOR SPD AT B-472

This 8(a) set-aside forecast from Navfac Southeast involves HVAC and environmental control modifications for the SPD at B-472. The project requires strict adherence to ASHRAE Standard 170 for air change rates, temperature, and relative humidity. Specifically, the sterile storage and clean work areas must utilize direct air from the air handler to maintain positive pressure, prohibiting the use of secondhand air from corridors. The clean work room must be maintained between 68-73 degrees Fahrenheit with a maximum 60 percent relative humidity, while sterile storage is capped at 75 degrees Fahrenheit. The soiled or decontamination room requires 2 ACH OA and 6 total ACH, with all air exhausted outside and temperatures kept between 60-73 degrees Fahrenheit. The contractor is required to implement and follow a comprehensive Infection Control Risk Assessment. Necessary precautions likely include the installation of air barriers, walk-off mats, and the use of mobile negative pressure zones. Additionally, the work area must be equipped with negative pressure alarms and pressure sensors to ensure safety and compliance throughout the duration of the project.
