Strategic Phasing and Minimal Disruption

Recognizing the critical nature of continuous operation within a functioning hospital, the project was executed in three phased construction stages. To minimize disruption to patient care, temporary air handling units were strategically installed in the neonatal Intensive Care Unit (NICU) and the Post-Intervention Recovery and Radiology (PIRR)/MRI units during each replacement phase. Construction staging was carefully coordinated to navigate the constraints of the urban location.

“Our primary goal was to enhance the hospital’s capabilities without interrupting its essential services,” stated Rich Heim, Project Manager at RMF. “Careful planning and seamless coordination were paramount to ensuring a smooth transition during the upgrade process.”

Future-Proofing for Growth and Safety

The new AHUs were designed to exceed current code requirements,incorporating increased airflow capacity to accommodate future expansion plans for the hospital’s Remote Terminal Units. Moreover, the upgraded systems feature high-efficiency filtration and ultraviolet (UV) lighting to significantly improve indoor air quality. According to the Environmental Protection Agency, enhanced filtration and UV light can dramatically reduce airborne pathogens.

Heim also emphasized the project’s proactive approach to preparedness, stating that the upgrades were partially driven by lessons learned during the Covid-19 pandemic. The enhanced air handling systems will help the hospital better manage potential future health crises.

Project Team Collaboration

The successful completion of this project relied on a collaborative effort from several firms, including architecture firm Azar design Co., structural engineering firm Siracuse Engineers PC, hazardous material abatement firm Encorus Group, and cost estimator Trophy Point.

SUNY Downstate: A Cornerstone of Brooklyn Healthcare

SUNY Downstate Health Sciences University is Brooklyn’s sole academic medical center and a leading training institution for physicians across New York City. The institution is currently benefiting from a larger, $1.1 billion state investment aimed at preserving and enhancing its services to the community.

“This project was fundamentally designed with the hospital’s long-term flexibility in mind,” Heim added. “By providing an additional 10 percent airflow capacity to the labor and delivery, NICU, and PIRR and MRI units, we have empowered them to advance their level of care as medical practices evolve.”
