Capitol Fire Sprinkler completes fire protection project in FiDi at 90 John St.

Manhattan, NY Capitol Fire Sprinkler completed a fire sprinkler system installation of 971 heads on floors three through eight at 90 John St., a rental property developed, owned and managed by The Moinian Group.

Also known as the Aria, 90 John St. features 114 studio and one-bedroom apartments. The office to residential conversion of the six floors Capitol Fire Sprinkler worked on was completed in late 2024.

“This is a meticulous conversion by one of the city’s preeminent owners and developers, so the work was carefully implemented in sections,” said Adam Levine, president, Capitol Fire Sprinkler. “Working in exceptionally large floor plates, featuring approximately 23 units per floor, our job was to ensure the project perfectly conformed to the design drawings.”

“We are committed to delivering high-quality living spaces that combine luxury, functionality, and safety,” said Robert Vahhabaghai, vice president of development at The Moinian Group. “Capitol Fire Sprinkler’s expertise was invaluable in ensuring that this critical infrastructure met the highest standards while seamlessly integrating into our conversion project. Their ability to execute with precision in a complex retrofit environment was key to maintaining our project timelines and delivering a top-tier residential experience.”

The Capitol Fire Sprinkler installation team was led by senior project manager Alfonso Cozzo, with a system designed in-house by Michael Ward, design engineer manager.
