St. Ignatius Chapel at Seattle University
Seattle, WAMacDonald-Miller: Mechanical Contractor
The system update needed on the St. Ignatius Chapel was unique as the building's mechanical room is located beneath the floor of the chapel. Every precaution was incorporated to minimize noise generation.
Project Overview
- The Fulton Pulse Combustion gas fired boiler is housed in its own room with all piping and equipment supported with spring isolators. The boiler provides heat to the Trane AHU controlled by a variable frequency drive.
- A Trane vaneaxial Q-Fan holds the responsibility of the return air. All ductwork, piping and equipment in the mechanical room are supported with spring isolation to minimize noise. From the mechanical room, the ductwork and piping travel through a crawl space until reaching each individual destination in the chapel floor above.
- The majority of penetrations are completely concealed behind walls or within a cabinet system. Exposed openings are concealed by custom cast bronze grilles.
- The baptismal font and reflecting pool systems posed a complicated but successful installation on the wet side. There were extensive modifications construed from the original design with the erection of the steel. This created complicated revamping of major duct runs, concealed within the walls. Through excellent field detailing, coordination and installation, this obstacle was overcome.
