AKRF provided full acoustical design services from Schematic Design through Construction Documents for The Touraine, a high-end luxury condominium located on Manhattan’s Upper East Side.

With construction of this 15-story condominium building adjacent to the Lexington Avenue subway—which on a typical weekday has more than 1,000 pass-bys—there was concern regarding subway-generated vibration levels entering the building structure and getting re-radiated as ground-borne noise inside the residences.

To investigate, AKRF performed a vibration survey to document existing subway-generated vibration levels, analyzed the results, and worked with the design team to develop a solution.

The result is New York City’s first “resiliently bedded” building to utilize the Getzner Sylodyn material full-surface. This state-of-the-art construction technology creates a fully isolated “floating” building that is decoupled from the ground. The entire building sits atop a specially engineered pad that acts like an enormous “spring” that reduces the amount of vibration energy that travels through it.

AKRF’s acoustical consulting services for this project also included:

  • Noise surveys to assess existing noise levels including auto, truck and bus traffic on Lexington Avenue
  • Review of glazing specifications to achieve desirable interior noise levels
  • Review of and recommendations for mechanical equipment to meet Noise and Mechanical Code requirements
  • Review of mechanical ductwork and recommendations to prevent cross-talk between units/adjacent rooms
  • Acoustical design for isolation of elevators, fitness center, and the trash chute/compactor
  • Design recommendations to control both airborne and impact sound transmission between units adjacent and above/beneath
  • ASTM E1007 impact sound testing to evaluate acoustical underlayments

In addition, AKRF provided Construction Administration Services, including submittal review and site inspections, for the project.
