Cerami is currently providing acoustical and audiovisual consulting services for the CUNY Hunter College School of Social Work. Located on Third Avenue between 118th and 119th Streets, the steel-framed SSW building has extensive floor-to-ceiling glass and brick cladding on the lower floors, and curtainwall and precast concrete panels on the upper levels making noise and vibration transmission an issue.
We advised on partition constructions for classrooms, computer labs, office, faculty lounge, bathrooms, mechanical risers, and primary passenger elevator shaft as well as finishes for classrooms, conference rooms, open office spaces, lobby, and library.
The 160-seat lecture hall is used by both CUNY and is also available to the public for events so it needs to be acoustically flexible to accommodate a wide variety of programs. We made recommendations for the finishes, slope angle of the ceiling, and carpet, and seat materials. Additionally, since the front of the lecture hall and full-height window is located on Third Avenue, we recommended a secondary slab-to-slab glazing separate from the curtainwall to palliate traffic noise.
We also provided recommendations to mitigate noise transmission of the emergency generator located in the basement with a remote radiator located on the sixth level roof, as well as the rooftop air handlers located on the fifth level roof.
