Cerami worked at the National Institute of Health on the Master Planning of Building 10 in Bethesda, MD to establish the design criteria for this renovation project, which included many vibration sensitive spaces such as animal facilities, operating rooms, and a linear accelerator room. We also reviewed various mechanical rooms and equipment to ensure that the equipment would not bother hospital employees or those receiving care at the hospital.

One of the greatest concerns for this project was the room with the linear accelerators. During construction, traffic was being routed along a path directly above the Radiation/Oncology Center, which is located underground. This presented two situations that needed to be addressed: the rolling loads of the loaded trucks driving through and the impulse when the trucks are loaded while on the access road. We conducted various sound level tests, and determined that even during the busiest times of the construction; the impact of the construction traffic would not compromise the integrity of the equipment.

Acoustical lining is a very important material used for controlling noise and vibration, but because of its absorptive qualities and the resulting threat of infection, it cannot be used in hospital projects. Therefore, we controlled the noise and vibration of mechanical systems through the careful selection of fan equipment with efficient operation and low noise levels. We also used packless silencers that have a plastic film between the air stream and the insulation, and are acceptable for use in hospitals.
