I love good design and a thoughtful use of space. I was so excited to see this project announced. This office tower originally designed by Norman Foster will be given new life as a mixed use tower designed by KPF. The repurposed building will house entertainment spaces, workspaces, retail, and homes. Congratulations to the project team on such a transformative vision. It seems since the pandemic, everybody has had something to say about how to repurpose empty office stock but I’ve seen few tangible projects. This is likely because it is a very complex technical and economic undertaking. A lot has to happen behind the scenes to make the building “work” for its new uses. Here are a few challenges from a noise and vibration perspective: - Floor “bounce” - commercial buildings often have lightweight floors that are flexible and can have some perceptible vibration when occupants move around. This may be acceptable for an office use, but imagine feeling your apartment floor move every time your neighbor walks by. - Building sway - all buildings move in the wind. Tall commercial buildings can move a lot. I’ve spent the 100s of hours helping stop “creaks” in a residential tower that swayed more than expected. I’ve heard these same noises in commercial buildings which are fine based on the occupancy, but could become a major problem if the space is used as a residence instead of office. - The noise isolation between floors may not be high enough. What works for general office use may not work for apartments, and particularly when you have entertainment or retail above or below apartments. - Building infrastructure isn’t typically designed to the same noise standard. Elevators, mechanical shafts, etc, could all be noisy when compared to a quiet residence. What’s amazing to me is that this is a relatively “new” tower, originally completed in 2002. I’m eagerly awaiting to see what buildings will undergo a similar transformation in NYC. The engineering nerd in me would love to take a crack at modeling the dynamics of the cantilevered structure at the top of the building... #acousticdesign #officeconversion #adaptivereuse

Excellent points! Completely agree that acoustic criteria in #AdaptiveReuse has to be considered as a fundamental strategy. Beautiful examples why this is important. This is such an exciting project!
