By engaging Cerami, the project team was able to leverage Cerami’s extensive experience in acoustics as well as the team’s collective experience working together to hone in on the issues that would have the greatest impact on the River Point tower. A key focus was on the glass used for the building’s façade; due to the proximity of the L, the project teams wanted to ensure that the glass used would deliver the appropriate level of reduction in sound desired. Cerami helped the project team select the right glass, of the appropriate thickness, to preserve the panoramic views they wanted while reducing noise from the trains.

Cerami also helped ensure that the noise from the building’s mechanical equipment had no negative impact on the acoustical environment of the top floors of the building. In addition to the mechanical equipment, River Point had a building maintenance unit (BMU) with a boom and piston that was designed to operate faster than what was typical of BMUs. The fast-moving piston, however, created acoustical problems 15 floors below—another unique challenge Cerami helped the project team solve. The end result was a comprehensive acoustical solution for the building that mitigated the impact of the nearby train and elevated rail lines, for an acoustical performance that would satisfy even the most demanding of future tenants.
