Project Portfolio

Project Overview

Replaced 140,000 CFM active built-up fan room located in the penthouse to eliminate the risk of a single fan failure at the hospital which could shut down the entire patient tower. 

Updated airside with a FANWALL array, while maintaining 140,000 CFM airflow in the building during the project.

Mechanical Highlights

• HVAC FANWALL design: two banks of FANWALL arrays, each five-wide by three-high.
• Redesign of ductwork and plenum walls.
• Relocation of piping to accommodate the new system.
• Relocation of major supply duct serving the birthing center.
• Fabricated and assembled platform in shop to keep on-site welding to a minimum.
• FANWALL arrays were assembled on each side of the existing vane axial fan before it was removed.  Each FANWALL array discharges into a common plenum that is ducted to cool or heat the building.
• FANWALL control system integrated into the existing Siemens Talon building automation system.
